Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Overview	1. Business Overview Biofrontera Inc. (the “Company” or “Biofrontera”) is a U.S.-based biopharmaceutical company commercializing a portfolio of pharmaceutical products for the treatment of dermatological conditions with a focus on photodynamic therapy (“PDT”) and topical antibiotics. The Company’s licensed products are used for the treatment of actinic keratoses, which are pre-cancerous skin lesions as well as impetigo, a bacterial skin infection. In May 2023, the Company began research and development (“R&D”) activities to support PDT growth and will continue to opportunistically invest in these activities going forward. Our research and development program currently aims to improve the capabilities of our BF-RhodoLED ® Biofrontera includes its wholly owned subsidiary Bio-FRI GmbH (“Bio-FRI”), a limited liability company organized under the laws of Germany. Our subsidiary, Bio-FRI was formed on February 9, 2022, as a German presence to facilitate our relationship with the Ameluz Licensor. Our principal licensed product is Ameluz ® ® ® Our second prescription drug licensed product is Xepi® (ozenoxacin cream, 1%), a topical non-fluorinated quinolone that inhibits bacterial growth. It is approved for use in the United States in adults and children 2 months and older. We are currently selling Xepi® for this indication in the United States under an exclusive license and supply agreement, as amended (“Xepi LSA”) with Ferrer Internacional S.A. (“Ferrer”) that was assumed by Biofrontera on March 25, 2019 through our acquisition of Cutanea Life Sciences, Inc.(“Cutanea”). There has been limited revenue during the current reporting periods and recent developments with the third-party manufacturer that was providing our supply of Xepi® have resulted in further delays of our commercialization of the product. However, Ferrer is qualifying a new Contract manufacturer, Cambrex, which is expected to begin production in 2024. Reverse Stock Split On June 28, 2023, the Company, filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation (the “Amendment”) with the Secretary of State of the State of Delaware to (i) effect a 1-for-20 0.001 300,000,000 15,000,000 Pursuant to the Amendment, the Reverse Stock Split and Authorized Share Reduction was effective at 11:59 p.m. on July 3, 2023 (the “Split Effective Time”), and the Common Stock began trading on the Nasdaq Capital Market on a post-split basis on July 5, 2023. The par value and other terms of the Common Stock were not affected. Following the Split Effective Time, every 20 shares of Biofrontera Common Stock issued and outstanding were automatically combined and reclassified into one share of Common Stock. Outstanding equity-based awards, warrants and other equity rights were proportionately adjusted pursuant to their terms and the number of shares authorized and reserved for issuance upon vesting of restricted stock units or exercise of stock options and warrants were reduced proportionately. No fractional shares were issued as a result of the Reverse Stock Split. Stockholders who would otherwise hold a fractional share as a result of the Reverse Stock Split received an additional share of Common Stock. Under the terms of the applicable warrant agreement, the number of shares of Common Stock issuable on exercise of each warrant will be proportionately decreased. Specifically, following effectiveness of the Reverse Stock Split, every 20 shares of Common Stock that may be purchased pursuant to the exercise of public warrants now represents one share of Common Stock that may be purchased pursuant to such warrants. Accordingly, for the Company’s warrants trading under the symbol “BFRIW”, every 20 warrants will be exercisable for one share of Common Stock at an exercise price of $ 100.00 The Reverse Stock Split affected all stockholders uniformly and did not alter any stockholder’s percentage interest in the Company’s equity (other than as a result of the rounding up of fractional shares). Liquidity and Going Concern The Company’s primary sources of liquidity are its existing cash balances, cash collected from the sales of its products, proceeds from the sale of our investment, related party, and cash flows from a revolving line of credit. As of September 30, 2023, we had cash and cash equivalents of $ 3.4 3.3 17.2 10.5 Since we commenced operations in 2015, we have generated significant losses. For the nine months ended September 30, 2023 and 2022, we incurred loss from operations of $ 18.8 million and $ 13.0 million, respectively. We incurred net cash outflows from operations of $ 16.0 million and $ 7.9 million, for the same periods, respectively. We had an accumulated deficit as of September 30, 2023 of $ 103.2 million. In connection with our assessment of going concern considerations under applicable accounting standards, the Company’s management has determined that substantial doubt exists about our ability to continue as a going concern for at least one year from the date the unaudited condensed consolidated financial statements were issued. The future viability of the Company is dependent on its ability to continue to execute its growth plan and raise additional capital or find alternative methods of financing to fund its operations during the first half of 2024, and until cash flow from operations is sufficient, if ever. We have implemented plans to improve our working capital position, particularly around inventory levels, and do not expect to need a delivery until sometime in Q3 2024, depending on actual sales until then. Management believes that the anticipated implementation of such plans, together with the recent net capital raise of $ 4.1 Subsequent Events The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above. There could be a material adverse effect on the Company and its financial statements if management’s plans are not achieved on a timely basis.	1.

Our principal licensed product is Ameluz ® ® ® ® Our second prescription drug licensed product is Xepi® (ozenoxacin cream, 1%), a topical non-fluorinated quinolone that inhibits bacterial growth. Currently, no antibiotic resistance against Xepi® is known and it has been specifically approved by the FDA for the treatment of impetigo, a common skin infection, due to Staphylococcus aureus or Streptococcus pyogenes. It is approved for use in the United States in adults and children 2 months and older. We are currently selling Xepi® for this indication in the United States under an exclusive license and supply agreement, as amended (“Xepi LSA”) with Ferrer Internacional S.A.

However, Ferrer is qualifying a new Contract manufacturer, Cambrex, which is expected to begin production early in 2024. Once the new third-party manufacturer is qualified, we expect the supply of Xepi® will meet our future market demand.

During the year ended December 31, 2022, we received proceeds of $ 9.4 4.6 Note 19. Stockholders’ Equity 17.2 24.5 Since we commenced operations in 2015, we have generated significant losses and have incurred net cash outflows from operations of $ 16.2 million and $ 26.7 million for the years ended December 31, 2022 and 2021. The Company had an accumulated deficit as of December 31, 2022 of $ 79.5 million. The Company’s short-term material cash requirements include working capital needs and satisfaction of contractual commitments, Maruho start-up payments of $ 7.3 million (see Note 3. Acquisition Contract Liabilities Note 24, Commitments and Contingencies Additionally, we expect to continue to incur operating losses due to significant discretionary sales and marketing, medical affairs, and dermatology community outreach efforts as we seek to expand the commercialization of our licensed products in the United States. We also expect to incur additional expenses to add and improve operational, financial and information systems and personnel, including personnel to support our product commercialization efforts. In addition, we expect to incur costs to continue to comply with corporate governance, regulatory reporting and other requirements applicable to us as a public company in the United States. In connection with our assessment of going concern considerations under applicable accounting standards, the Company’s management has determined that substantial doubt exists about our ability to continue as a going concern for at least one year from the date these financial statements were issued. The future viability of the Company is dependent on management’s plans to continue to execute its growth plan and raise additional capital or find alternative methods of financing to fund its operations until cash flow from operations is sufficient. Management believes that actions presently being taken to obtain additional funding and implement its strategic plans provide the opportunity for the Company to continue as a going concern. No assurance can be given that the Company will be successful in these efforts. Accordingly, management has concluded that substantial doubt exists about the company’s ability to continue as a going concern for a period of at least 12 months from the date of issuance of these financial statements. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above. There could be a material adverse effect on the Company and its financial statements if management’s plans are not achieved on a timely basis.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis for Preparation of the Financial Statements The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In the Company’s opinion, the unaudited condensed consolidated financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly the Company’s financial position as of September 30, 2023, the Company’s operating results for the three and nine months ended September 30, 2023 and 2022, and the Company’s cash flows for the nine months ended September 30, 2023 and 2022. The accompanying financial information as of December 31, 2022 is derived from audited financial statements. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s reaudited consolidated financial statements for the fiscal years ended December 31, 2022 and 2021 (“reaudited Consolidated Financial Statements”), and the revised Management’s Discussion and Analysis of Financial Condition and Results of Operations for the fiscal years ended December 31, 2022 and December 31, 2021 (“revised MD&A”), filed in a Current Report on From 8-K with the SEC on October 3, 2023. All amounts shown in these financial statements and tables are in thousands and amounts in the notes are in millions, except percentages and per share and share amounts. With the exception of the accounting policies below, there have been no new or material changes to the significant accounting policies discussed in the Company’s reaudited Consolidated Financial Statements.: Reverse Stock Split All information included in these consolidated financial statements has been adjusted, on a retrospective basis, to reflect the Reverse Stock Split as if it had been effective from the beginning of the earliest period presented, unless otherwise stated. All outstanding securities entitling their holders to purchase shares of Common Stock or acquire shares of Common Stock, including stock options, restricted stock units, and warrants, were adjusted as a result of the Reverse Stock Split, as required by the terms of those securities. Research and Development Costs Research and development costs are expensed as incurred. Research and development costs include external costs of outside vendors engaged to conduct research and development activities, and other operational costs related to the Company’s research and development activities. Use of Estimates The preparation of the financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions by management that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities, as reported on the balance sheet date, and the reported amounts of revenues and expenses arising during the reporting period. The main areas in which assumptions, estimates and the exercising of judgment are appropriate relate to, valuation allowances for receivables and inventory, valuation of contingent consideration and warrant liabilities, realization of intangible and other long-lived assets, product sales allowances and reserves, share-based payments and income taxes including deferred tax assets and liabilities. Estimates are based on historical experience and other assumptions that are considered appropriate in the circumstances. They are continuously reviewed but may vary from the actual values. Recently Adopted Accounting Pronouncements In September 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	2. Summary of Significant Accounting Policies Basis for Preparation of the Consolidated Financial Statements Basis for Preparation of the Financial Statements The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These consolidated financial statements include the accounts of our wholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. The information presented reflects the application of significant accounting policies described below. All amounts shown in these financial statements and tables are in thousands and amounts in the notes are in millions, except percentages and per share and share amounts. Segment Reporting Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The Company’s chief operating decision maker (determined to be the Chief Executive Officer) does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s operating results. We operate in a single reporting segment, the commercialization of pharmaceutical products for the treatment of dermatological conditions and diseases within the U.S. All business operations focus on the products Ameluz ® ® ® Reverse Stock Split On July 3, 2023 Biofrontera Inc. effected a 1-for-20 reverse stock split (the “Reverse Stock Split”) of the issued and outstanding shares of the Company’s common stock, $0.001 par value (the “Common Stock”). The Common Stock began trading on the Nasdaq Capital Market on a post-split basis on July 5, 2023. All information included in these consolidated financial statements has been adjusted, on a retrospective basis, to reflect the Reverse Stock Split as if it had been effective from the beginning of the earliest period presented, unless otherwise stated. All outstanding securities entitling their holders to purchase shares of Common Stock or acquire shares of Common Stock, including stock options, restricted stock units, and warrants, were adjusted as a result of the Reverse Stock Split, as required by the terms of those securities. Use of Estimates The preparation of the consolidated financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions by management that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities, as reported on the balance sheet date, and the reported amounts of revenues and expenses arising during the reporting period. The main areas in which assumptions, estimates and the exercising of judgment are appropriate relate to valuation allowances for receivables and inventory, valuation of contingent consideration and warrant liabilities, realization of intangible and other long-lived assets, product sales allowances and reserves, share-based payments and income taxes including deferred tax assets and liabilities. Estimates are based on historical experience and other assumptions that are considered appropriate in the circumstances. They are continuously reviewed but may vary from the actual values. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less at the time of purchase to be cash equivalents. The Company maintains its cash balances at financial institutions that are insured by the Federal Deposit Insurance Corporation (“FDIC”). The FDIC provides coverage of up to $250,000 per depositor, per financial institution. At December 31, 2022, approximately $16.8 million of the Company’s cash balances were in excess of FDIC limits. The Company has not experienced any losses on these accounts and management does not believe that the Company is exposed to any significant risks. Restricted Cash Restricted cash consists primarily of deposits of cash collateral held in accordance with the terms of our corporate credit cards, in addition to one deposit held for a sublease (see Note 13. Statement of Cash Flows Reconciliation) Investment, Related Party T he Company accounts for its investment, related party in accordance with ASC 321, Investments — Equity Securities Accounts Receivable Accounts receivables are reported at their net realizable value. Any value adjustments are booked directly against the relevant receivable. We have standard payment terms that generally require payment within approximately 30 to 90 days. Management performs ongoing credit evaluations of its customers. An allowance for potentially uncollectible accounts is provided based on history, economic conditions, and composition of the accounts receivable aging. In some cases, the Company makes allowances for specific customers based on these and other factors. Provisions for the allowance for doubtful accounts are recorded in selling, general and administrative expenses in the accompanying statements of operations. Concentration of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, accounts receivable and other receivables, related party. The Company maintains all of its cash and cash equivalents at a single accredited financial institution, in amounts that exceed federally insured limits. The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Concentrations of credit risk with respect to receivables, which are typically unsecured, are somewhat mitigated due to the wide variety of customers using our products. We monitor the financial performance and creditworthiness of our customers so that we can properly assess and respond to changes in their credit profile. We continue to monitor these conditions and assess their possible impact on our business. Other receivables, related party consists of a receivable due from Biofrontera AG for its 50% share of a legal settlement and related costs for which they are jointly and severally liable for the total settlement amount. The Company has a contractual right to repayment of its share of the settlement payment from Biofrontera AG under the Settlement Allocation Agreement entered into on December 9, 2021, which provided that the settlement payments would first be made by the Company and then reimbursed by Biofrontera AG for its share. Although this receivable has credit risk, it is mitigated by the Settlement Allocation Agreement as amended on March 31, 2022, which provides certain remedies to the Company, if Biofrontera AG fails to make timely reimbursements, which the Company may implement in its sole discretion, including the ability to charge interest at a rate of 6.0% per annum for each day that any reimbursement is past due and the ability to offset any overdue reimbursement amounts against payments owed to Biofrontera AG by the Company ® We are dependent on two suppliers, Biofrontera Pharma GmbH and Ferrer Internacional S.A., to supply drug products, including all underlying components, for our commercial efforts. These efforts could be adversely affected by a significant interruption in the supply of our finished products. Inventories Finished goods consist of pharmaceutical products purchased for resale and are stated at the lower of cost or net realizable value. Cost is calculated by applying the first-in-first-out method (FIFO). Inventory costs include the purchase price of finished goods and freight-in costs. The Company regularly reviews inventory quantities on hand and writes down to its net realizable value any inventory that it believes to be impaired. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back up if demand increases. Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Depreciation is generally applied straight-line over the estimated useful life of assets. Leasehold improvements are amortized over the shorter of the asset’s estimated useful life or the lease term. The estimated useful lives of property and equipment are: Schedule of Estimated Useful Lives of Property, Plant and Equipment Estimated Useful Life in Years Computer equipment 3 Computer software 3 Furniture and fixtures 3 5 Leasehold improvements Shorter of estimated useful lives or the term of the lease Machinery & equipment 3 4 The cost and accumulated depreciation of assets retired or sold are removed from the respective asset category, and any gain or loss is recognized in our statements of operations. Intangible Assets Intangible assets with finite lives are amortized over their estimated useful lives. Intangible assets with indefinite lives are not amortized. Leases In February 2016, the Financial Accounting Standards Board (“ 1.8 At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes its incremental borrowing rate (“IBR”), which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Given the absence of an outstanding debt agreement, a synthetic credit rating analysis was used in estimating the Company’s IBR. Based on a synthetic credit rating of Ba3 and a term of 3.33 to six years, the IBR was determined to be 6% for lease liabilities at inception and 8.5% for 2022 lease liabilities. No adjustments to the right-of-use asset were required for items such as initial direct costs paid or incentives received. The Company has elected to adopt the practical expedient provided in ASC 842 and not reassess leases that existed prior to the commencement date, 1). Whether any expired or existing contracts are or contain leases, 2). Lease classification, or 3). Initial indirect costs for any existing leases. The Company has elected to combine lease and non-lease components as a single component for certain asset classes, when applicable. Operating leases are recognized on the balance sheet as operating lease right-of-use assets, operating lease liabilities current and operating lease liabilities non-current. Impairment of Long-Lived Assets The Company considers whether events or changes in facts and circumstances, both internally and externally, may indicate that an impairment of long-lived assets held for use, including right-of-use assets, are present. To the extent indicators or impairment exist, the determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset, the assets are written down to their estimated fair values and the loss is recognized in the statements of operations. Refer to Note 12. Intangible Asset, Net. Contingent Consideration Contingent consideration in a business combination is included as part of the acquisition cost and is recognized at fair value as of the acquisition date. For contingent consideration, management is responsible for determining the appropriate valuation model and estimated fair value, and in doing so, considers a number of factors, including information provided by an outside valuation advisor. Contingent consideration liabilities are reported at their estimated fair values based on probability-adjusted present values of the consideration expected to be paid, using significant inputs and estimates. Key assumptions used in these estimates include probability assessments with respect to the likelihood of achieving certain milestones and discount rates consistent with the level of risk of achievement. The fair value of contingent consideration liabilities are remeasured each reporting period, with changes in the fair value included in current operations. The remeasured liability amount could be significantly different from the amount at the acquisition date, resulting in material charges or credits in future reporting periods. Contingencies Loss contingency provisions are recorded if the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable, and the amount can be reasonably estimated or a range of loss can be determined. These accruals represent management’s best estimate of probable loss. Disclosure also is provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded provision. On a quarterly basis, we review the status of each significant matter and assess its potential financial exposure. Significant judgment is required in both the determination of probability and as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and may change our estimates. Legal costs associated with legal proceedings are expensed when incurred. Derivative Instruments The Company accounts for common stock warrants as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants and applicable authoritative guidance in FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and Derivatives and Hedging (“ASC 815”). Warrants classified as equity are recorded at fair value as of the date of issuance on the Company’s consolidated balance sheets and no further adjustments to their valuation are made. Warrants classified as derivative liabilities that require separate accounting as liabilities are recorded on the Company’s consolidated balance sheets at their fair value on the date of issuance and are revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair value between reporting periods recorded as other income or expense. Management estimates the fair value of these liabilities using the Black-Scholes-Merton (“BSM”) model and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, as well as assumptions for future financings, expected volatility, expected life, yield, and risk-free interest rate. At their issuance date in October 2021, the IPO Warrants (see Note 19. Stockholders’ Equity) were accounted for as equity as these instruments met all of the requirements for equity classification under ASC 815-40. The Purchase Warrants issued in connection with the private placement offerings completed on December 1 , ASC 815-40. The resulting warrant liabilities are re-measured at each balance sheet date until their exercise or expiration, and any change in fair value is recognized in the Company’s consolidated statement of operations. Refer to Note 4. Fair Value Measurements. Fair Value Measurements The Company is required to disclose information on all assets and liabilities reported at fair value that enables an assessment of the inputs used in determining the reported fair values. ASC 820, Fair Value Measurements and Disclosures Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 – Unobservable inputs using estimates or assumptions developed by the Company, which reflect those that a market participant would use in pricing the asset or liability. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Fair Value of Financial Instruments The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, accounts receivable, other receivables, accounts payable and start-up cost financing included in acquisition contract liabilities approximate their fair values, due to their short-term nature. Revenue Recognition The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers To determine revenue recognition, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step model to contracts when collectability of the consideration to which we are entitled in exchange for the goods or services we transfer to the customer is determined to be probable. The Company realizes its revenue primarily through the sales of its Ameluz ® Xepi ® The payment terms for sales of our pharmaceutical products are generally short-term payment terms with the possibility of volume-based discounts, co-pay assistance discounts, or other rebates. BF RhodoLED ® Variable Consideration Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which sales reserves are established and which result from discounts, rebates and other incentives that are offered within contracts between the Company and its customers. Components of variable consideration include trade discounts and allowances, product returns, government rebates, and other incentives such as patient co-pay assistance. Variable consideration is recorded on the balance sheet as either a reduction of accounts receivable, if expected to be claimed by a customer, or as a current liability, if expected to be payable to a third party other than a customer. Where appropriate, these estimates take into consideration relevant factors such as the Company’s historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. These reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, and record any necessary adjustments in the period such variances become known. Trade Discounts and Allowances Government and Payor Rebates Other Incentives ® Royalties For arrangements that include sales-based royalties, the Company recognizes royalty expense at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Royalty expense is recognized as cost of revenues. Product Warranty The Company generally provides a 36-month warranty for sales of BF-RhodoLED ® ® Contract Costs Incremental costs of obtaining a contract with a customer may be recorded as an asset if the costs are expected to be recovered. As a practical expedient, we recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. Sales commissions earned by the Company’s sales force are considered incremental costs of obtaining a contract. To date, we have expensed sales commissions as these costs are generally attributed to periods shorter than one year. Sales commissions are included in selling, general and administrative expenses. Cost of Revenues Cost of revenues is comprised of purchase costs of our products, third party logistics and distribution costs including packaging, freight, transportation, shipping and handling costs, and inventory adjustment due to expiring products, as well as sales-based royalties. Logistics and distribution costs totaled $ 0.5 0.4 Share-Based Compensation The Company measures and recognizes share-based compensation expense for equity awards based on fair value at the grant date. The Company uses the Black-Scholes-Merton (“BSM”) option pricing model to calculate fair value of its stock option grants. The compensation cost for restricted stock awards is based on the closing price of the Company’s common stock on the date of grant. Share-based compensation expense recognized in the statements of operations is based on the period the services are performed and recognized as compensation expense on a straight-line basis over the requisite service period. The Company accounts for forfeitures as they occur. The BSM option pricing model requires the input of subjective assumptions, including the risk-free interest rate, the expected volatility of the value of the Company’s common stock, and the expected term of the option. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the share-based compensation expense could be materially different in the future. These assumptions are estimated as follows: Risk-Free Interest Rate. The risk-free rate is based on the interest rate payable on United States Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected term. Expected Volatility. The Company based the volatility assumption on a weighted average of the peer group re-levered equity volatility with 80 20 Expected Term. The expected term represents the period of time that options are expected to be outstanding. Due to the lack of historical exercise data and given the plain vanilla nature of the options granted by the Company, the expected term is determined using the “simplified” method, as prescribed in SEC Staff Accounting Bulletin (“SAB”) No. 107 (“SAB 107”), whereby the expected life equals the average of the vesting term and the original contractual term. Dividend Yield. The dividend yield is 0 Foreign Currency Transactions Transactions realized in currencies other than USD are reported using the exchange rate on the date of the transaction. Selling, General and Administrative Expense Selling, general and administrative expenses are primarily comprised of compensation and benefits associated with our sales force, commercial support personnel, personnel in executive and other administrative functions, as well as medical affairs professionals. Other selling, general and administrative expenses include marketing, advertising, and other commercial costs to support the commercial operation of our product and professional fees for legal, consulting, and other general and administrative costs. Advertising costs are expensed as incurred. For the years ended December 31, 2022 and 2021, advertising costs totaled $ 0.1 0.5 Income Taxes The Company accounts for income taxes using the asset and liability method in accordance with ASC 740, Income Taxes The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties. Net Loss per Share Basic and diluted net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding. When the effects are not anti-dilutive, diluted earnings per share is computed by dividing the Company’s net income attributable to common stockholders by the weighted average number of common shares outstanding and the impact of all dilutive potential common shares outstanding during the period, including stock options, restricted stock units, and warrants, using the treasury stock method.

Fair Value Measurements The following table presents information about the Company’s assets that are measured at fair value on a recurring basis at September 30, 2023 and December 31, 2022 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Schedule of Fair Value Hierarchy Valuation Inputs (in thousands) Level September 30, 2023 December 31, 2022 Assets: Investment, related party 1 $ 3,341 $ 10,548 Liabilities: Contingent Consideration 3 $ 2,500 $ 2,400 Warrant liability – 2022 Purchase Warrants 3 $ 366 $ 1,129 Warrant liability - 2022 Inducement Warrants 3 $ 476 $ 1,714 Warrant liability 3 $ 476 $ 1,714 Investment, related party A s of September 30, 2023 and December 31, 2022, the Company has an investment in 5,745,678 6,446,946 company traded on the Frankfurt Stock Exchange Note 6. Investment Related Party and Note 13. Related Party Transactions. Contingent Consideration Contingent consideration, which relates to the estimated profits from the sale of Cutanea products to be shared equally with Maruho, is reflected at fair value within acquisition contract liabilities, net on the consolidated balance sheets. The fair value is based on significant inputs not observable in the market, which represent a Level 3 measurement within the fair value hierarchy. The valuation of the contingent consideration utilizes a scenario-based method under which a set of payoffs are calculated using the term of the earnout, projections, and an appropriate metric risk premium. These payoffs are then discounted back from the payment date to the valuation date using a payment discount rate. The scenario-based method incorporates the following key assumptions: (i) the forecasted product profit amounts, (ii) the remaining contractual term, (iii) a metric risk premium, and (iv) a payment discount rate. The Company re-measures contingent consideration and re-assesses the underlying assumptions and estimates at each reporting period. The following table provides a roll forward of the fair value of the contingent consideration: Schedule of Fair Value of Contingent Consideration (in thousands) Balance at December 31, 2022 $ 2,400 Change in fair value of contingent consideration 100 Balance at September 30, 2023 $ 2,500 Balance at December 31, 2021 $ 6,200 Change in fair value of contingent consideration (4,100 ) Balance at September 30, 2022 $ 2,100 Warrant Liabilities The warrant liabilities are comprised of (i) currently outstanding 170,950 55.40 214,286 33.20 The Company utilizes a Black-Scholes option pricing model to estimate the fair value of the Purchase Warrants and Inducement Warrants which is considered a Level 3 fair value measurement. Certain inputs utilized in our Black-Scholes pricing model may fluctuate in future periods based upon factors which are outside of the Company’s control. A significant change in one or more of these inputs used in the calculation of fair value may cause a significant change to the fair value of our warrant liabilities which could also result in material non-cash gain or loss being reported in our consolidated statements of operations. The fair value for the Level 3 warrants at September 30, 2023 was estimated using a Black-Scholes pricing model based on the following assumptions: Schedule of Fair Value Warrant by Using Black-Scholes Pricing Model Assumptions Purchase Inducement Stock price $ 8.77 $ 8.77 Expiration term (in years) 4.13 3.17 Volatility 80.0 % 80 % Risk-free Rate 4.63 % 4.73 % Dividend yield 0.0 % 0.0 % The fair value for the Level 3 warrants at December 31, 2022 was estimated using a Black-Scholes pricing model based on the following assumptions: Purchase Inducement Stock price $ 18.40 $ 18.40 Expiration term (in years) 4.88 3.92 Volatility 70.0 % 75 % Risk-free Rate 3.96 % 4.07 % Dividend yield 0.0 % 0.0 % The following table presents the changes in the Level 3 warrant liabilities measured at fair value (in thousands): Schedule of Changes in Level 3 Warrant Liabilities 2023 2022 Nine Months Ended September 30, 2023 2022 Fair value at beginning of period $ 2,843 $ 12,854 Issuance of new warrants - 13,217 Exercise of warrants - (6,840 ) Change in fair value of warrant liabilities (2,001 ) (15,267 ) Fair value at end of period $ 842 $ 3,964	4. Fair Value Measurements The following table presents information about the Company’s assets that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Schedule of Fair Value Hierarchy Valuation Inputs (in thousands) Level December 31, 2022 December 31, 2021 Assets: Investment, related party 1 $ 10,548 $ - Liabilities: Contingent Consideration 3 $ 2,400 $ 6,200 Warrant liability – 2021 Purchase Warrants 3 $ - $ 12,854 Warrant liability - 2022 Purchase Warrants 3 $ 1,129 $ - Warrant liability - Purchase Warrants 3 $ 1,129 $ - Warrant liability – 2022 Inducement Warrants 3 $ 1,714 $ - Warrant liability 3 $ 1,714 $ - Investment, related party A s of December 31, 2022, the Company had investments in common stock of Biofrontera AG, a significant shareholder. The fair value of these investments was determined with Level 1 inputs through references to quoted market prices. Contingent Consideration Contingent consideration, which relates to the estimated profits from the sale of Cutanea products to be shared equally with Maruho, is reflected at fair value within acquisition contract liabilities, net on the consolidated balance sheets. The fair value is based on significant inputs not observable in the market, which represent a Level 3 measurement within the fair value hierarchy. The valuation of the contingent consideration utilizes a scenario-based method under which a set of payoffs are calculated using the term of the earnout, projections, and an appropriate metric risk premium. These payoffs are then discounted back from the payment date to the valuation date using a payment discount rate. Finally, the discounted payments are summed together to arrive at the value of the contingent consideration. The scenario-based method incorporates the following key assumptions: (i) the forecasted product profit amounts, (ii) the remaining contractual term, (iii) a metric risk premium, and (iv) a payment discount rate. The Company re-measures contingent consideration and re-assesses the underlying assumptions and estimates at each reporting period. The following table provides a roll forward of the fair value of the contingent consideration: Schedule of Fair Value of Contingent Consideration (in thousands) Balance at December 31, 2020 $ 7,602 Change in fair value of contingent consideration (1,402 ) Balance at December 31, 2021 $ 6,200 Change in fair value of contingent consideration (3,800 ) Balance at December 31, 2022 $ 2,400 The decrease in fair value of the contingent consideration in the amount of $ (3.8) (1.4) Warrant Liabilities The Purchase and Inducement Warrants were accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities in the accompanying consolidated balance sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within the consolidated statement of operations. Given the nominal strike price of $0.001, the fair value of the Pre-funded Warrant was deemed to be equal to the market price of the underlying common stock at issuance and at each reporting period and is considered a level 2 liability. The Pre-funded Warrant was issued and exercised within the same year and therefore is not reflected in the ending balance. The Company utilizes a Black-Scholes option pricing model to estimate the fair value of the Purchase and Inducement Warrants which is considered a Level 3 fair value measurement. Certain inputs utilized in our Black-Scholes pricing model may fluctuate in future periods based upon factors which are outside of the Company’s control. A significant change in one or more of these inputs used in the calculation of the fair value may cause a significant change to the fair value of our warrant liabilities which could also result in material non-cash gain or loss being reported in our consolidated statement of operations. The fair value at issuance was estimated using a Black-Scholes pricing model based on the following assumptions at December 1, 2021 for the 2021 Purchase Warrants, May 16, 2022 for the Purchase Warrants and July 26, 2022 for the Inducement Warrants: Schedule of Fair value Warrant by Using Black-Scholes Pricing Model Assumptions 2021 Purchase Purchase Inducement Stock price $ 86.60 $ 52.40 $ 32.80 Expiration term (in years) 5 5.50 4.34 Volatility 60.0 % 65.0 % 70.0 % Risk-free Rate 1.15 % 2.83 % 2.84 % Dividend yield 0.0 % 0.0 % 0.0 % The fair value was estimated using Black-Scholes pricing model based on the following assumptions as of December 31, 2021: 2021 Purchase Stock price $ 150.40 Expiration term (in years) 4.92 Volatility 60.0 % Risk-free Rate 1.25 % Dividend yield 0.0 % The fair value was estimated using Black-Scholes pricing model based on the following assumptions as of December 31, 2022 (outstanding warrants were all issued during 2022): Purchase Inducement Stock price $ 18.40 $ 18.40 Expiration term (in years) 4.88 3.92 Volatility 70 % 75 % Risk-free Rate 3.96 % 4.07 % Dividend yield 0.0 % 0.0 % Dividend yield 0.0 % 0.0 % The following table presents the changes in the warrant liabilities measured at fair value (in thousands): Schedule of Changes in Fair Value Warrant Liabilities December 31, 2022 December 31, 2021 Fair value at beginning of year $ 12,854 $ - Issuance of new warrants 13,217 12,261 Exercise of warrants (6,840 ) (12,208 ) Change in fair value of warrant liability (19,017 ) 12,801 Warrant inducement expense 2,629 - Fair value at end of year $ 2,843 12,854

Net Earnings (Loss) per Share	17. Net Earnings (Loss) per Share Basic net earnings (loss) per common share are calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net earnings per common share are calculated by dividing net income (loss) by the diluted weighted average number of common shares outstanding during the period. The diluted shares include the dilutive effect of stock-based awards based on the treasury stock method. In periods where a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be anti-dilutive.

On November 29, 2021, the Company entered into a settlement and release agreement with respect to a lawsuit filed March 23, 2018 in the United States District Court for the District of Massachusetts in which we were alleged to have infringed on certain patents and misappropriated certain trade secrets. In the settlement, the Company and Biofrontera AG together agreed to make an aggregate payment of $ 22.5 While Biofrontera AG has agreed to pay fifty percent of the settlement costs, we remain jointly and severally liable to DUSA Pharmaceuticals Inc. (“DUSA”) for the full cash settlement amount, meaning that in the event Biofrontera AG does not pay all or a portion of the amount it owes under the settlement agreement, DUSA could compel us to pay Biofrontera AG’s share. As of September 30, 2023, we have reflected a legal settlement liability in the amount of $ 6.0 2.8 Settlement Agreement with Biofrontera AG Pursuant to the terms of that certain Settlement Agreement, dated as of April 11, 2023, among the Company, Biofrontera AG and certain current and former directors of the Company (the “Settlement Agreement”), the Company has taken or committed, among other things, to take the following actions: ● On July 7, 2023, in connection with the Biofrontera AG settlement agreement, the board of directors of the Company appointed Heikki Lanckriet to the Board. Mr. Lanckriet will serve as a Class I Director to hold office for a term expiring at the annual meeting of the Company’s stockholders for fiscal year 2025. Mr. Lanckriet’s term as director began upon his appointment at the July 7, 2023 meeting. ● The Company will begin a search, pursuant to the conditions set forth in the Settlement Agreement including a strike right granted to the aforementioned director nominated by Biofrontera AG, for an additional director candidate, who is fully independent from Biofrontera AG, Deutsche Balaton Aktiengesellschaft (“DB”) and any of their respective affiliates, to be nominated for election as a Class II Director at the Company’s 2024 annual meeting of stockholders. ● The Board will increase its size to seven members, including the two directors appointed and elected pursuant to the Settlement Agreement as noted above. In addition, the Settlement Agreement contains provisions to maintain Biofrontera AG’s representation on the Board of Directors as long as it holds at least 20% of the Company’s outstanding common stock and to limit further increases in the size of the Board of Directors or changes to the Company’s stockholder rights plan. Under the Settlement Agreement, Biofrontera AG also agrees, subject to certain conditions, to vote in support of the directors nominated by, and the proposals recommended by, the Board of Directors. Legal Claim On September 13, 2023, Biofrontera was served with a complaint filed in United Stated District Court for the District of Massachusetts by DUSA Pharmaceuticals, Inc., Sun Pharmaceutical Industries, Inc., and Sun Pharmaceutical Industries LTD (collectively “DUSA” or “Plaintiffs”) in which DUSA alleges breach of contract, violation of the Lanham Act, and unfair trade practices. All claims stem from allegations that Biofrontera has promoted its Ameluz product in a manner that is inconsistent with its approved FDA labeling. Though this complaint was originally filed in the U.S. District Court for the District of Massachusetts, this matter has been transferred by agreement of the parties to the U.S. District Court for the District of New Jersey. The Company denies the Plaintiffs’ claims and intends to defend these matters vigorously. Based on the Company’s assessment of the facts underlying the above claims, the uncertainty of litigation and the preliminary stage of the case, the Company cannot estimate the possibility of a material loss, nor the potential range of loss that may result from this action. If the final resolution of the matter is adverse to the Company, it could have a material impact on the Company’s financial position, results of operations, or cash flows.	24. Commitments and Contingencies Facility Leases The Company leases its corporate headquarters under an operating lease that expires in August 2025. The Company has the option to extend the term of the lease for one five (5) year period 0.1 The Company has also entered into a master lease agreement for its vehicles. After an initial non-cancelable twelve-month period each vehicle is leased on a month to month basis. Based on historical retention experience of approximately three years, the vehicles have expiration dates ranging from February 2023 through September 2025. In calculating the present value of the lease payments, the Company has elected to utilize its incremental borrowing rate based on the original lease term and not the remaining lease term. Based on a synthetic credit rating of Ba3 and a term of 3.33 to six years, the IBR was determined to be 6% for leased liabilities at inception and 8.5% for 2022 leased liabilities. The components of lease expense for the year ended December 31, 2022 was as follows (in thousands except lease term and discount rate): Schedule of Components of Lease Expense and Other Information Lease expense Operating Leases Amortization of ROU assets (operating lease cost) $ 653 Interest on lease liabilities 99 Total lease expense $ 752 Other Information Operational cash flow used for operating leases $ 781 ROU assets obtained in exchange for lease liabilities 234 Weighted -average remaining lease term (in years) 2.54 Weighted -average discount rate 6.31 % Future lease payments under non-cancelable leases as of December 31, 2022 were as follows (in thousands): Schedule of Future Commitments and Sublease Income Years ending December 31, Future lease commitments 2023 565 2024 541 2025 349 Thereafter - Total future minimum lease payments $ 1,455 Less imputed interest $ (109 ) Total lease liability $ 1,346 Schedule of Operating Lease Liability Reported as: Operating lease liability, current $ 498 Operating lease liability, non-current 848 Total 1,346 Cutanea payments We have a contract in which we agreed to repay to Maruho $ 3.6 3.7 We have filed for arbitration against Maruho with the International Chamber of Commerce (“ICC”) regarding issues with Maruho’s contract manufacturer that were not disclosed at the time of the Agreement and therefore are evaluating the repayment of the $ 7.3 million of start-up costs. The arbitration notes that Maruho breached the agreement with Cutanea due to the undisclosed manufacturing issues and seeks damages as well as a declaration that we are not obligated to repay Maruho. We are also obligated to share product profits with Maruho equally from January 1, 2020 through October 30, 2030. Refer to Note 3, Acquisition Contract Liabilities Milestone payments with Ferrer Internacional S.A. Under the Xepi LSA, we are obligated to make payments to Ferrer upon the occurrence of certain milestones. Specifically, we must pay Ferrer i) $ 2,000,000 upon the first occasion when annual net sales of Xepi ® 25,000,000 , and ii) $ 4,000,000 upon the first occasion annual net sales of Xepi ® 50,000,000 . No payments were made in 2022 or 2021 related to Xepi ® Contingent liability related to shares of Biofrontera AG acquired from Maruho through subscription rights Dependent on the outcome of legal proceedings between Biofrontera AG and Maruho, the Company may be liable for an additional payout of $ 0.9 Contingencies, Note 26. Subsequent Events. Legal proceedings At each reporting date, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of FASB ASC Topic 450, Contingencies On November 29, 2021, the Company entered into a settlement and release agreement with respect to a lawsuit filed March 23, 2018 in the United States District Court for the District of Massachusetts in which we were alleged to have infringed on certain patents and misappropriated certain trade secrets. In the settlement, the Company and Biofrontera AG together agreed to make an aggregate payment of $ 22.5 While Biofrontera AG has agreed to pay fifty percent of the settlement costs, we remain jointly and severally liable to DUSA for the full cash settlement amount, meaning that in the event Biofrontera AG does not pay all or a portion of the amount it owes under the Agreement, DUSA could compel us to pay Biofrontera AG’s share. If either we or Biofrontera AG violates the terms of the settlement agreement, we or Biofrontera AG may be liable for a greater amount. If we become liable for more than our agreed share of the aggregate settlement amount, either of these events could have a material adverse effect on our business, prospects, financial condition and/or results of operations. As of December 31, 2022, the remaining legal settlement liability accrued for was $ 6.2 million, including the estimated remaining cost of the forensic expert.

Licensing Agreement with Optical Tools On December 2, 2022, the Company entered into the technology transfer agreement with Optical Tools LLC (“Optical Tools”), and Stephen Tobin and Paul Sowyrda (the “Agreement”).

Mr. Lanckriet’s term as director began upon his appointment at the July 7, 2023 meeting.

Contingent liability related to shares of Biofrontera AG acquired from Maruho through subscription rights relieved in 2023. In July 2023, AG and Maruho settled the dispute from which the contingent payment obligation of Biofrontera Inc. under the subscription rights agreement could have arisen. Legal Claim On September 13, 2023, Biofrontera was served with a complaint filed in United Stated District Court for the District of Massachusetts by DUSA Pharmaceuticals, Inc., Sun Pharmaceutical Industries, Inc., and Sun Pharmaceutical Industries LTD (collectively “DUSA” or “Plaintiffs”) in which DUSA alleges breach of contract, violation of the Lanham Act, and unfair trade practices. All claims stem from allegations that Biofrontera has promoted its Ameluz product in a manner that is inconsistent with its approved FDA labeling. Though this complaint was originally filed in the U.S. District Court for the District of Massachusetts, this matter has been transferred by agreement of the parties to the U.S. District Court for the District of New Jersey. The Company denies the Plaintiffs’ claims and intends to defend these matters vigorously. Based on the Company’s assessment of the facts underlying the above claims, the uncertainty of litigation and the preliminary stage of the case, the Company cannot estimate the possibility of a material loss, nor the potential range of loss that may result from this action. If the final resolution of the matter is adverse to the Company, it could have a material impact on the Company’s financial position, results of operations, or cash flows.

Segment Reporting		Segment Reporting Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The Company’s chief operating decision maker (determined to be the Chief Executive Officer) does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s operating results. We operate in a single reporting segment, the commercialization of pharmaceutical products for the treatment of dermatological conditions and diseases within the U.S. All business operations focus on the products Ameluz ® ® ®

The main areas in which assumptions, estimates and the exercising of judgment are appropriate relate to, valuation allowances for receivables and inventory, valuation of contingent consideration and warrant liabilities, realization of intangible and other long-lived assets, product sales allowances and reserves, share-based payments and income taxes including deferred tax assets and liabilities. Estimates are based on historical experience and other assumptions that are considered appropriate in the circumstances. They are continuously reviewed but may vary from the actual values.

Cash and Cash Equivalents		Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less at the time of purchase to be cash equivalents. The Company maintains its cash balances at financial institutions that are insured by the Federal Deposit Insurance Corporation (“FDIC”). The FDIC provides coverage of up to $250,000 per depositor, per financial institution. At December 31, 2022, approximately $16.8 million of the Company’s cash balances were in excess of FDIC limits. The Company has not experienced any losses on these accounts and management does not believe that the Company is exposed to any significant risks.
Restricted Cash		Restricted Cash Restricted cash consists primarily of deposits of cash collateral held in accordance with the terms of our corporate credit cards, in addition to one deposit held for a sublease (see Note 13. Statement of Cash Flows Reconciliation)
Investment, Related Party		Investment, Related Party T he Company accounts for its investment, related party in accordance with ASC 321, Investments — Equity Securities
Accounts Receivable		Accounts Receivable Accounts receivables are reported at their net realizable value. Any value adjustments are booked directly against the relevant receivable. We have standard payment terms that generally require payment within approximately 30 to 90 days. Management performs ongoing credit evaluations of its customers. An allowance for potentially uncollectible accounts is provided based on history, economic conditions, and composition of the accounts receivable aging. In some cases, the Company makes allowances for specific customers based on these and other factors. Provisions for the allowance for doubtful accounts are recorded in selling, general and administrative expenses in the accompanying statements of operations.
Concentration of Credit Risk and Off-Balance Sheet Risk		Concentration of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, accounts receivable and other receivables, related party. The Company maintains all of its cash and cash equivalents at a single accredited financial institution, in amounts that exceed federally insured limits. The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Concentrations of credit risk with respect to receivables, which are typically unsecured, are somewhat mitigated due to the wide variety of customers using our products. We monitor the financial performance and creditworthiness of our customers so that we can properly assess and respond to changes in their credit profile. We continue to monitor these conditions and assess their possible impact on our business. Other receivables, related party consists of a receivable due from Biofrontera AG for its 50% share of a legal settlement and related costs for which they are jointly and severally liable for the total settlement amount. The Company has a contractual right to repayment of its share of the settlement payment from Biofrontera AG under the Settlement Allocation Agreement entered into on December 9, 2021, which provided that the settlement payments would first be made by the Company and then reimbursed by Biofrontera AG for its share. Although this receivable has credit risk, it is mitigated by the Settlement Allocation Agreement as amended on March 31, 2022, which provides certain remedies to the Company, if Biofrontera AG fails to make timely reimbursements, which the Company may implement in its sole discretion, including the ability to charge interest at a rate of 6.0% per annum for each day that any reimbursement is past due and the ability to offset any overdue reimbursement amounts against payments owed to Biofrontera AG by the Company ® We are dependent on two suppliers, Biofrontera Pharma GmbH and Ferrer Internacional S.A., to supply drug products, including all underlying components, for our commercial efforts. These efforts could be adversely affected by a significant interruption in the supply of our finished products.
Inventories		Inventories Finished goods consist of pharmaceutical products purchased for resale and are stated at the lower of cost or net realizable value. Cost is calculated by applying the first-in-first-out method (FIFO). Inventory costs include the purchase price of finished goods and freight-in costs. The Company regularly reviews inventory quantities on hand and writes down to its net realizable value any inventory that it believes to be impaired. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back up if demand increases.
Property and Equipment		Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Depreciation is generally applied straight-line over the estimated useful life of assets. Leasehold improvements are amortized over the shorter of the asset’s estimated useful life or the lease term.

Intangible Assets		Intangible Assets Intangible assets with finite lives are amortized over their estimated useful lives. Intangible assets with indefinite lives are not amortized.
Leases		Leases In February 2016, the Financial Accounting Standards Board (“ 1.8 At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes its incremental borrowing rate (“IBR”), which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Given the absence of an outstanding debt agreement, a synthetic credit rating analysis was used in estimating the Company’s IBR. Based on a synthetic credit rating of Ba3 and a term of 3.33 to six years, the IBR was determined to be 6% for lease liabilities at inception and 8.5% for 2022 lease liabilities. No adjustments to the right-of-use asset were required for items such as initial direct costs paid or incentives received. The Company has elected to adopt the practical expedient provided in ASC 842 and not reassess leases that existed prior to the commencement date, 1). Whether any expired or existing contracts are or contain leases, 2). Lease classification, or 3). Initial indirect costs for any existing leases. The Company has elected to combine lease and non-lease components as a single component for certain asset classes, when applicable. Operating leases are recognized on the balance sheet as operating lease right-of-use assets, operating lease liabilities current and operating lease liabilities non-current.
Impairment of Long-Lived Assets		Impairment of Long-Lived Assets The Company considers whether events or changes in facts and circumstances, both internally and externally, may indicate that an impairment of long-lived assets held for use, including right-of-use assets, are present. To the extent indicators or impairment exist, the determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset, the assets are written down to their estimated fair values and the loss is recognized in the statements of operations. Refer to Note 12. Intangible Asset, Net.
Contingent Consideration		Contingent Consideration Contingent consideration in a business combination is included as part of the acquisition cost and is recognized at fair value as of the acquisition date. For contingent consideration, management is responsible for determining the appropriate valuation model and estimated fair value, and in doing so, considers a number of factors, including information provided by an outside valuation advisor. Contingent consideration liabilities are reported at their estimated fair values based on probability-adjusted present values of the consideration expected to be paid, using significant inputs and estimates. Key assumptions used in these estimates include probability assessments with respect to the likelihood of achieving certain milestones and discount rates consistent with the level of risk of achievement. The fair value of contingent consideration liabilities are remeasured each reporting period, with changes in the fair value included in current operations. The remeasured liability amount could be significantly different from the amount at the acquisition date, resulting in material charges or credits in future reporting periods.
Contingencies		Contingencies Loss contingency provisions are recorded if the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable, and the amount can be reasonably estimated or a range of loss can be determined. These accruals represent management’s best estimate of probable loss. Disclosure also is provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded provision. On a quarterly basis, we review the status of each significant matter and assess its potential financial exposure. Significant judgment is required in both the determination of probability and as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and may change our estimates. Legal costs associated with legal proceedings are expensed when incurred.
Derivative Instruments		Derivative Instruments The Company accounts for common stock warrants as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants and applicable authoritative guidance in FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and Derivatives and Hedging (“ASC 815”). Warrants classified as equity are recorded at fair value as of the date of issuance on the Company’s consolidated balance sheets and no further adjustments to their valuation are made. Warrants classified as derivative liabilities that require separate accounting as liabilities are recorded on the Company’s consolidated balance sheets at their fair value on the date of issuance and are revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair value between reporting periods recorded as other income or expense. Management estimates the fair value of these liabilities using the Black-Scholes-Merton (“BSM”) model and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, as well as assumptions for future financings, expected volatility, expected life, yield, and risk-free interest rate. At their issuance date in October 2021, the IPO Warrants (see Note 19. Stockholders’ Equity) were accounted for as equity as these instruments met all of the requirements for equity classification under ASC 815-40. The Purchase Warrants issued in connection with the private placement offerings completed on December 1 , ASC 815-40. The resulting warrant liabilities are re-measured at each balance sheet date until their exercise or expiration, and any change in fair value is recognized in the Company’s consolidated statement of operations. Refer to Note 4. Fair Value Measurements.
Fair Value Measurements		Fair Value Measurements The Company is required to disclose information on all assets and liabilities reported at fair value that enables an assessment of the inputs used in determining the reported fair values. ASC 820, Fair Value Measurements and Disclosures Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 – Unobservable inputs using estimates or assumptions developed by the Company, which reflect those that a market participant would use in pricing the asset or liability. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
Fair Value of Financial Instruments		Fair Value of Financial Instruments The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, accounts receivable, other receivables, accounts payable and start-up cost financing included in acquisition contract liabilities approximate their fair values, due to their short-term nature.
Revenue Recognition		Revenue Recognition The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers To determine revenue recognition, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step model to contracts when collectability of the consideration to which we are entitled in exchange for the goods or services we transfer to the customer is determined to be probable. The Company realizes its revenue primarily through the sales of its Ameluz ® Xepi ® The payment terms for sales of our pharmaceutical products are generally short-term payment terms with the possibility of volume-based discounts, co-pay assistance discounts, or other rebates. BF RhodoLED ® Variable Consideration Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which sales reserves are established and which result from discounts, rebates and other incentives that are offered within contracts between the Company and its customers. Components of variable consideration include trade discounts and allowances, product returns, government rebates, and other incentives such as patient co-pay assistance. Variable consideration is recorded on the balance sheet as either a reduction of accounts receivable, if expected to be claimed by a customer, or as a current liability, if expected to be payable to a third party other than a customer. Where appropriate, these estimates take into consideration relevant factors such as the Company’s historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. These reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, and record any necessary adjustments in the period such variances become known. Trade Discounts and Allowances Government and Payor Rebates Other Incentives ® Royalties For arrangements that include sales-based royalties, the Company recognizes royalty expense at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Royalty expense is recognized as cost of revenues. Product Warranty The Company generally provides a 36-month warranty for sales of BF-RhodoLED ® ® Contract Costs Incremental costs of obtaining a contract with a customer may be recorded as an asset if the costs are expected to be recovered. As a practical expedient, we recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. Sales commissions earned by the Company’s sales force are considered incremental costs of obtaining a contract. To date, we have expensed sales commissions as these costs are generally attributed to periods shorter than one year. Sales commissions are included in selling, general and administrative expenses.
Cost of Revenues		Cost of Revenues Cost of revenues is comprised of purchase costs of our products, third party logistics and distribution costs including packaging, freight, transportation, shipping and handling costs, and inventory adjustment due to expiring products, as well as sales-based royalties. Logistics and distribution costs totaled $ 0.5 0.4
Share-Based Compensation		Share-Based Compensation The Company measures and recognizes share-based compensation expense for equity awards based on fair value at the grant date. The Company uses the Black-Scholes-Merton (“BSM”) option pricing model to calculate fair value of its stock option grants. The compensation cost for restricted stock awards is based on the closing price of the Company’s common stock on the date of grant. Share-based compensation expense recognized in the statements of operations is based on the period the services are performed and recognized as compensation expense on a straight-line basis over the requisite service period. The Company accounts for forfeitures as they occur. The BSM option pricing model requires the input of subjective assumptions, including the risk-free interest rate, the expected volatility of the value of the Company’s common stock, and the expected term of the option. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the share-based compensation expense could be materially different in the future. These assumptions are estimated as follows: Risk-Free Interest Rate. The risk-free rate is based on the interest rate payable on United States Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected term. Expected Volatility. The Company based the volatility assumption on a weighted average of the peer group re-levered equity volatility with 80 20 Expected Term. The expected term represents the period of time that options are expected to be outstanding. Due to the lack of historical exercise data and given the plain vanilla nature of the options granted by the Company, the expected term is determined using the “simplified” method, as prescribed in SEC Staff Accounting Bulletin (“SAB”) No. 107 (“SAB 107”), whereby the expected life equals the average of the vesting term and the original contractual term. Dividend Yield. The dividend yield is 0
Foreign Currency Transactions		Foreign Currency Transactions Transactions realized in currencies other than USD are reported using the exchange rate on the date of the transaction.
Selling, General and Administrative Expense		Selling, General and Administrative Expense Selling, general and administrative expenses are primarily comprised of compensation and benefits associated with our sales force, commercial support personnel, personnel in executive and other administrative functions, as well as medical affairs professionals. Other selling, general and administrative expenses include marketing, advertising, and other commercial costs to support the commercial operation of our product and professional fees for legal, consulting, and other general and administrative costs. Advertising costs are expensed as incurred. For the years ended December 31, 2022 and 2021, advertising costs totaled $ 0.1 0.5
Income Taxes		Income Taxes The Company accounts for income taxes using the asset and liability method in accordance with ASC 740, Income Taxes The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.
Net Loss per Share		Net Loss per Share Basic and diluted net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding. When the effects are not anti-dilutive, diluted earnings per share is computed by dividing the Company’s net income attributable to common stockholders by the weighted average number of common shares outstanding and the impact of all dilutive potential common shares outstanding during the period, including stock options, restricted stock units, and warrants, using the treasury stock method.
