Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS Apyx Medical Corporation (“Company”, “Apyx”, “it” and similar terms) was incorporated in 1982, under the laws of the State of Delaware and has its principal executive office at 5115 Ulmerton Road, Clearwater, FL 33760. The Company is an advanced energy technology company with a passion for elevating people’s lives through innovative products, including its Helium Plasma Technology products marketed and sold as Renuvion® in the cosmetic surgery market and J-Plasma® in the hospital surgical market. Renuvion and J-Plasma offer surgeons a unique ability to provide controlled heat to tissue to achieve their desired results. The Company also leverages its deep expertise and decades of experience in unique waveforms through OEM agreements with other medical device manufacturers. Recent Business Developments On March 14, 2022, the U.S. Food and Drug Administration (“FDA”) posted a Safety Communication that warned consumers and health care providers against the use of the Company’s Advanced Energy products outside of their FDA-cleared indications for general use in cutting, coagulation, and ablation of soft tissue during open and laparoscopic surgical procedures. Following the Safety Communication, the Company experienced reduced demand for the adoption of its Helium Plasma Technology. On May 26, 2022, the Company announced that it had received 510(k) clearance from the FDA for the use of the Renuvion Dermal handpiece for specific dermal resurfacing procedures. On July 18, 2022, the Company announced that it had received 510(k) clearance from the FDA for the use of the Renuvion APR handpiece for certain skin contraction procedures. On June 2, 2022, and July 21, 2022, the FDA updated the Medical Device Safety Communication to recognize the new 510(k) clearances for the Renuvion Dermal handpiece, and the expanded indications for the Renuvion® APR handpiece. The 510(k) clearance for the Renuvion Dermal handpiece allows surgeons to perform dermal resurfacing procedures for the treatment of moderate to severe wrinkles and rhytides, limited to patients with Fitzpatrick Skin Types I, II or III. The 510(k) clearance for the Renuvion APR handpieces now addresses improving the appearance of lax (loose) skin in the neck and submental region. On February 27, 2023, the Company announced that it received 510(k) clearance from the FDA for the use of the Renuvion APR handpiece for the delivery of radiofrequency energy and/or helium plasma where coagulation/contraction of soft tissue is needed. Soft tissue includes subcutaneous tissue. On April 28, 2023, the Company announced it had received 510(k) clearance from the FDA for the use of the Renuvion APR handpiece for coagulation of subcutaneous soft tissues following liposuction for aesthetic body contouring. On May 10, 2023, the FDA updated the Safety Communication to inform consumers and healthcare providers about the clearance for the Renuvion APR handpiece for coagulation of subcutaneous soft tissues following liposuction. On June 14, 2023, the Company announced that we received 510(k) clearance from the FDA for the Renuvion Micro handpiece, a new addition to the Renuvion production family. The Renuvion Micro handpiece was cleared with an indication for the delivery of radiofrequency energy and/or helium plasma where coagulation/contraction of soft tissue is needed. Soft tissue includes subcutaneous tissue. Liquidity The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company has incurred recurring net losses and cash outflows from operations and it anticipates that losses will continue in the near term. For the year ended December 31, 2023, the Company incurred a loss from operations of $17.3 million and used $5.2 million of cash in operations, which is inclusive of the receipt of its tax refund of approximately $8.1 million. As of December 31, 2023, cash and cash equivalents on-hand were $43.7 million. The Company plans to continue to fund its operations and capital funding needs through existing cash, sales of our products and if necessary additional equity and/or debt financing. However, it cannot be certain that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to the Company or its existing stockholders. The sale of additional equity would result in dilution to the Company’s stockholders. Incurring additional debt financing would result in further debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict the Company’s operations. If the Company is unable to raise additional capital in sufficient amounts or on acceptable terms, it may be required to delay, limit, reduce, or terminate its sales, marketing and product development. Any of these actions could harm the business, results of operations and prospects. On November 22, 2022, the Company filed a shelf registration statement providing it the ability to register and sell securities in the aggregate amount up to $100 million. The shelf registration included an embedded ATM facility for up to $40 million. To date the Company has not utilized this facility. On February 17, 2023, the Company entered into a Credit, Security and Guaranty Agreement (the “MidCap Credit Agreement”) with MidCap Funding IV Trust (as agent), and MidCap Financial Trust (as term loan servicer), and the lenders party thereto from time to time. The MidCap Credit Agreement provided for an up to $35 million facility, consisting of senior secured term loans and a secured revolving facility. The MidCap Credit Agreement provided for senior secured term loans of up to $25 million, comprised of (i) an initial tranche of $10 million, (ii) a second tranche of $5 million, and (iii) a third tranche of $10 million. The secured revolving facility provided for loans in an aggregate principal amount of up to $10 million, subject to a borrowing base equal to certain percentages of the Company’s eligible accounts receivable and inventory, as determined in accordance with the terms of the MidCap Credit Agreement. The MidCap Credit Agreement was extinguished when, on November 8, 2023, when we entered into a Credit and Guaranty Agreement (the “Perceptive Credit Agreement”), by and among Apyx Medical (as borrower), Apyx China Holding Corp. and Apyx Bulgaria EOOD, our wholly-owned subsidiaries (as subsidiary guarantors), and Perceptive Credit Holdings IV, LP (as initial lender and administrative agent)(“Perceptive”), and the lenders from time to time party thereto. The Perceptive Credit Agreement provides for a facility of up to $45 million, consisting of senior secured term loans. The Perceptive Credit Agreement provides for (i) an initial loan of $37.5 million and (ii) a delayed draw loan of $7.5 million. For a more in-depth description of the terms of the MidCap Credit Agreement and the Perceptive Credit Agreement, see Note 11. On February 27, 2023, the Company’s Board of Directors approved a plan to sell and leaseback the Company’s real property located in Clearwater, FL. On March 14, 2023, the Company entered into a Purchase and Sale Agreement (the “Purchase Agreement”) with VK Acquisitions VI, LLC (the “Purchaser”), for the sale of the Company’s facility located at 5115 Ulmerton Road, Clearwater, Florida, as more fully described in the Purchase Agreement (collectively, the “Property”) for a purchase price of $7,650,000. On May 8, 2023, the Company closed on the Purchase Agreement and concurrently executed a 10-year agreement to leaseback the underlying Property from the Purchaser. For a more in-depth description of the terms of the Purchase Agreement, see Notes 6 and 7. During January 2023, the Company was notified that the IRS examination process of our 2018, 2019 and 2020 tax returns was complete and that the Company’s tax refunds were approved for approximately $0.2 million more than the amount recorded in the Company’s Consolidated Balance Sheet at December 31, 2022. On August 10, 2023, the Company received $8.1 million from the IRS, which included approximately $0.4 million of interest on the $7.7 million income tax refunds. Management believes that the actions already taken, including replacing the MidCap Credit Agreement with the Perceptive Credit Agreement, alleviated the conditions that previously raised substantial doubt about the Company’s ability to continue as a going concern for a period of at least one year from the date of issuance of its Consolidated Financial Statements.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Consolidated Financial Statements The accompanying consolidated financial statements include the accounts of Apyx, its wholly owned subsidiary, Apyx Bulgaria, EOOD, and its 51% owned subsidiary, Apyx SY Medical Devices (Ningbo) Co., Ltd. (collectively, “Apyx,” or the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation. Use of Estimates in the Preparation of Financial Statements The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. The reported amounts of revenues and expenses during the reporting period may be affected by the estimates and assumptions the Company is required to make. Cash and Cash Equivalents Holdings of highly liquid investments with original maturities of three months or less from the date of purchase are considered to be cash equivalents. As of December 31, 2023 and 2022, all of the Company’s investments are in money market funds or in Treasury Bills with original maturities of three months or less and are included in cash and cash equivalents. Concentration of Credit Risk Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of trade accounts receivable. With respect to cash, the Company frequently maintains cash and cash equivalent balances in excess of federally insured limits. However, it has not experienced any losses in such accounts. Trade Accounts Receivable and Allowance for Credit Losses The Company’s standard credit terms for billings range from net 30 days to net 120 days, depending on the customer agreement. However, management is able to use discretion in actual terms granted to customers. Accounts receivable are determined to be past due if payments are not made in accordance with such agreements. When evaluating the adequacy of the allowance for credit losses, we analyze historical bad debt experience, the composition of outstanding receivables by customer class, and the age of outstanding balances, and we make estimates in connection with establishing the allowance for credit losses, including the expected impacts of changes in the operating environment and other trends. Changes in estimates are reflected in the period they are made. If the financial condition of our customers deteriorates, resulting in an inability to make payments, additional allowances may be required. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. Management believes that the allowances for credit losses of approximately $0.6 million and $0.7 million at December 31, 2023 and 2022, respectively, are adequate to provide for probable credit losses. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first in, first out basis. Finished goods and work-in-process inventories include material, labor and overhead costs. Factory overhead costs are allocated to manufactured inventory based upon labor hours. The Company monitors inventory usage to determine if the carrying value of any items should be adjusted due to lack of demand for the item and adjusts inventory for estimated obsolescence or unusable inventory equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. Property and Equipment Property and equipment are recorded at cost. Depreciation and amortization are provided for using the straight-line method over the estimated useful lives of the assets. The amortization of leasehold improvements is based on the shorter of the lease term or the life of the improvement. Betterments and major improvements, which extend the life of the asset, are capitalized, whereas maintenance and repairs and routine improvements are expensed as incurred. The estimated useful lives are: buildings and improvements, 39 years; machinery and equipment, 3-10 years; furniture and fixtures, 5-10 years; computer equipment and software, 3-5 years; and molds, 7-15 years. Valuation of Long-Lived Assets The Company reviews long-lived assets for recoverability if events or changes in circumstances indicate that the assets may have been impaired. This circumstance exists when the carrying amount of the asset exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. In those cases, an impairment loss is recognized to the extent that the assets’ carrying amount exceeds its fair value. Any impairment losses are not restored in the future if the fair value increases. At December 31, 2023 and 2022, the Company believes the remaining carrying values of its long-lived assets are recoverable. Leases The Company does not recognize leases with terms less than twelve months in duration, or that have variable only payments, in its Consolidated Balance Sheets as right-of-use assets and lease liabilities. The Company has adopted the practical expedient which allows for the Company to not separate lease and non-lease components of contracts. Accordingly, non-lease components are included in the measurement of the Company’s lease liabilities and right-of-use assets. If the Company is aware of the implicit rate in leases, the Company determines the operating lease liability using the implicit rate. For those leases where the Company is not aware of the implicit rate in the lease, the Company utilizes an incremental borrowing rate, which is indicative of its collateralized borrowing rate. Rates utilized were 1.83% to 9.09% for our outstanding leases at December 31, 2023. Product Warranties The Company provides a four-year limited warranty on end-user sales of its Renuvion and J-Plasma generators, a two year warranty on mounting fixtures, and a one-year warranty on certain accessories. The Company estimates and provides for future costs for product warranties in cost of sales at the time revenue is recognized. The Company bases its product warranty costs on related material costs, repair labor costs and shipping costs. The Company estimates the future cost of product warranties by considering historical material, repair labor, and shipping costs, and applying the experience rates to the outstanding warranty period for products sold. It is reasonably possible that actual results could differ from those estimates. Debt and Debt Issuance Costs Proceeds allocated to debt instruments are recorded net of discounts, such as those resulting from other financial instruments issued in a debt transaction or bifurcated embedded derivative features within the debt agreement, and debt issuance costs. Debt issuance costs are allocated to issued and unissued financial instruments based on costs incurred and the underlying commitments in the debt agreement. At the inception of the debt instrument, the Company determined the fair value of the debt and other financial instruments, including warrants and bifurcated embedded derivatives, and allocated the proceeds to each financial instrument based upon these estimated fair values. Debt issuance costs allocated to unissued financial instruments are deferred as an asset until the financial instrument is issued. Debt discounts and issuance costs are amortized over the estimated life of issued debt using the effective interest method and are presented as reduction of the related debt. Revenue Recognition Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that the Company expects to receive for those goods or services. To recognize revenue, the Company (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when, or as, it satisfies the performance obligation(s). For sales of the Company's Advanced Energy products (Renuvion and J-Plasma), this is at a point in time when title has been transferred to the customer, which is generally at the time of shipment or receipt by customer for FOB destination terms. For sales of products under its OEM agreements, the Company recognizes revenue over time when no alternative use exists for the manufactured goods and the Company has rights to payment. Presently, the Company does not stock any significant completed goods under its OEM agreements, accordingly, the recognition of revenue under these agreements approximates point in time recognition. The following policies apply to its major categories of revenue transactions: • The majority of sales to customers are evidenced by firm purchase orders. Generally, title and the risks and rewards of ownership are transferred to the customer when the product is shipped. Payment by the customer is due under fixed payment terms. • Product returns are only accepted at the Company's discretion and in accordance with its “Returned Goods Policy”. Historically, the level of product returns has not been significant. Accruals for sales returns, rebates and allowances are made as a reduction of revenue based upon an analysis of historical customer returns and credits, rebates, discounts and current market conditions. • The terms of sale to customers generally do not include any obligations to perform future services. Limited warranties are generally provided for sales and provisions for warranty are provided at the time of product sale based upon an analysis of historical data. • In connection with the execution of OEM supply agreements, the Company may enter into an accompanying product development agreement. If the Company enters into a product development agreement, and development of the goods does not represent a performance obligation on a standalone basis, the Company defers the development fees billed to customers and the associated costs. Recognition of the deferred billings and costs occurs as the Company performs on the accompanying supply arrangements. Advertising Costs Advertising costs are expensed as incurred. The amounts of advertising costs, including trade shows, direct to consumer advertising and other related costs, were approximately $1.8 million and $2.3 million for the years ended December 31, 2023, and 2022, respectively. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, Compensation-Stock Compensation . FASB ASC 718 requires recognizing compensation expense for all share-based payment awards made to employees, directors and non-employees based upon the grant date fair value of such awards. It accounts for forfeitures as they occur. The standard covers employee stock options, restricted stock and other equity awards. The Company utilizes a Black-Scholes model to estimate the grant date fair value of stock option awards. For employee and director awards, compensation expense is recognized on a straight-line basis over the vesting periods. For non-employee awards, compensation expense is recorded for non-forfeitable, fully vested awards at the grant date. For other awards granted to non-employees, compensation cost is recognized as services are provided, which approximates a straight-line basis over the vesting period. Litigation Contingencies In accordance with authoritative guidance, the Company accrues a liability in its consolidated financial statements when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible, but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed in the notes to the consolidated financial statements. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded; actual results may differ from those estimates. Earnings (Loss) Per Share The Company computes basic (loss) earnings attributable to common stockholders per share by dividing net (loss) income attributable to common stockholders by the weighted average number of common shares outstanding for the reporting period. Diluted (loss) earnings per share attributable to common stockholders gives effect to all potential dilutive shares outstanding during the period. The number of dilutive shares is calculated using the treasury stock method which reduces the effective number of shares by the amount of shares the Company could purchase with the proceeds of assumed exercises. Anti-dilutive units are excluded from the calculation of diluted shares. In periods of loss, all potentially dilutive units are anti-dilutive and are excluded from the calculation of diluted income (loss) per share. Research and Development Costs Research and development expenses are charged to operations as incurred. The amounts of research and development costs were approximately $4.8 million and $4.5 million for the years ended December 31, 2023 and 2022, respectively. Income Taxes The Company utilizes the liability method of accounting for income taxes as set forth in FASB ASC Topic 740, Income Taxes . Under the liability method, deferred taxes are determined based on temporary differences between the financial statement and tax bases of assets and liabilities using tax rates expected to be in effect during the years in which the deferred taxes reverse. The Company accounts for interest and penalties on income taxes as income tax expense. A valuation allowance is recorded when it is more likely than not that a tax benefit will not be realized. In determining the need for valuation allowances the Company considers projected future taxable income, the timing of reversals of temporary differences, and the availability of tax planning strategies. As of December 31, 2023 and 2022, the Company recorded a valuation allowance on its net deferred tax assets. The Company assesses the realizability of deferred tax assets each reporting period and will be able to reduce the valuation allowance to the extent the financial results of continuing operations improve, and it becomes more likely than not that the deferred tax assets will be realized. As Management has not fully determined the timing of when it will generate taxable income in the U.S., the Company will continue to record a full valuation allowance on the net deferred tax assets as of December 31, 2023. The Company assesses the financial statement impact of an uncertain tax position taken or expected to be taken on an income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized in the financial statements unless it is more likely than not of being sustained. Foreign Currency Transactions The functional currency of Apyx Bulgaria is the U.S. dollar. The monetary assets and liabilities that are denominated in a currency other than U.S. dollar are remeasured into U.S. dollars at the exchange rate on the balance sheet date, while non-monetary items are remeasured at historical rates. Revenue and expenses are remeasured at weighted average exchange rates during the period. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in selling, general and administrative expenses in the Consolidated Statements of Operations and were not material for the years ended December 31, 2023 and 2022. Reclassifications The Company has reclassified certain amounts presented in the prior year to conform to the current year presentation. These reclassifications had no impact on previously reported net income, retained earnings or operating cash flows for the periods presented.

Accounting Standards Update and Change in Accounting Principle [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). The update changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, contract assets, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update, as originally issued, was effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) Effective Dates , which deferred the effective dates of these standards for Smaller Reporting Companies until fiscal years beginning after December 15, 2022. The Company adopted ASU 2016-13 on January 1, 2023, and its impact was not material to the Company. No other new accounting pronouncement issued or effective during the fiscal year had or is expected to have a material impact on the Company's consolidated financial statements or disclosures.

The MidCap Credit Agreement provided for an up to $35 million facility, consisting of senior secured term loans and a secured revolving facility. The MidCap Credit Agreement provided for senior secured term loans of up to $25 million, comprised of (i) an initial tranche of $10 million, (ii) a second tranche of $5 million, and (iii) a third tranche of $10 million. The secured revolving facility provided for loans in an aggregate principal amount of up to $10 million, subject to a borrowing base equal to percentages of eligible accounts receivable and inventory determined in accordance with the MidCap Credit Agreement. The MidCap Credit Agreement was to mature on February 1, 2028. The outstanding borrowings under the MidCap Credit Agreement were repaid in full using proceeds from the execution of the Perceptive Credit Agreement. Issuance of MidCap Warrants In connection with the Company’s obligations under the MidCap Credit Agreement, the Company issued to a statutory trust of MidCap Financial warrants to purchase up to 250,000 shares of its common stock, par value $0.001, with an exercise price of $3.40 per share. These warrants remain outstanding as of December 31, 2023. The warrants have a 10 year term and can be exercised by issuing payment to the Company for the number of warrants exercised or exercised net by surrendering warrants with an intrinsic value equal to the cumulative exercise price of the warrants being exercised. The Company determined that these warrants meet the criteria for equity classification and included the proceeds allocated to the warrants, on a relative fair value basis, as a debt discount and additional paid-in capital in the accompanying consolidated financial statements. MidCap Debt Issuance Costs In connection with entering into the MidCap Credit Agreement, the Company incurred debt issuance costs of approximately $1.6 million, comprised primarily of commissions paid to the financial advisor. These costs were allocated to the issued and unissued term loans and the revolving facility. The costs allocated to the issued term loan were being amortized using the effective interest method over the life of the loan. The costs allocated to the unissued term loans were deferred and were being amortized over the life of the term loans starting at the issuance date. The Company recognized the deferred costs at the point that the Company’s rights to borrow on the term loans expired. The costs allocated to the revolving facility were being recognized on a straight-line basis over the term of the MidCap Credit Agreement. Together with unamortized debt discounts and prepayment penalties incurred in the extinguishment, the Company recognized all unamortized debt issuance costs in loss on extinguishment of debt in the accompanying Consolidated Statement of Operations for the year ended December 31, 2023.

The Perceptive Credit Agreement provides for a facility of up to $45 million, consisting of senior secured term loans. The Perceptive Credit Agreement provides for (i) an initial loan of $37.5 million and (ii) a delayed draw loan of $7.5 million. The Credit Agreement matures on November 8, 2028. Loans The initial loan of $37.5 million was fully funded on November 8, 2023, with approximately $11.0 million of the proceeds used to payoff the obligations under the MidCap Credit Agreement, including approximately $1.0 million of related prepayment penalties and exit fees, and $2.7 million for transaction fees and other expenses incurred in connection with the Perceptive Credit Agreement, which included a 2% fee of the total facility payable to Perceptive at closing. The delayed draw loan is available until December 31, 2024, conditioned upon, among other things, the achievement of a minimum revenue target. After repayment of the MidCap Credit Agreement and payment of transaction fees and other expenses in connection with the Perceptive Credit Agreement, the net proceeds of these loans will be used for working capital and general corporate purposes. The initial loan and delayed draw loan bear interest at a floating rate based on one-month SOFR, subject to a floor of 5.0%, plus 7.0% (12.4% at December 31, 2023). The first forty-eight (48) months of the loans constitute an interest-only period, with interest payable monthly on the last day of each month. Subsequent to the interest-only period, the outstanding principal amount of the loans is repayable in monthly payments of 3% of the outstanding balance on the payment date. All remaining outstanding principal, together with all accrued and unpaid interest, is due at maturity. The loans may be voluntarily prepaid in full, or in part, at any time, subject to terms and conditions set forth in the Perceptive Credit Agreement. Additionally, the loans are subject to mandatory prepayment obligations, pursuant to the terms of the Perceptive Credit Agreement. Prepayments of the loans are subject to fees of 10%, 9%, 6%, 4% and 2% of the prepayment amounts made during the first year, second year, third year, fourth year, and thereafter, respectively. Collateral The obligations of the Company under the Perceptive Credit Agreement are secured by first priority liens on substantially all of its assets. Covenants The Perceptive Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company and its subsidiaries, among other things, to incur debt, grant liens, make distributions, enter certain restrictive agreements, pay or modify subordinated debt, dispose of assets, make investments and acquisitions, enter into certain transactions with affiliates, and undergo certain fundamental changes, in each case, subject to limitations and exceptions set forth in the Perceptive Credit Agreement. The Perceptive Credit Agreement also requires the Company to satisfy certain financial covenants, including minimum trailing twelve month net revenue targets relating to its Advanced Energy segment (tested quarterly), with year-end targets of $41.6 million, $57.0 million, $70.2 million, and $87.8 million for 2024, 2025, 2026, and 2027, respectively. Additionally, the Company must maintain a balance of $3 million in cash and cash equivalents during the duration of the Perceptive Credit Agreement’s term. As of December 31, 2023, the Company was in compliance with the financial covenants contained within the Perceptive Credit Agreement. Events of Default The Perceptive Credit Agreement also contains customary Events of Default (as defined in the Perceptive Credit Agreement) that include, among other things, certain payment defaults, cross defaults to certain other contracts and indebtedness, covenant defaults, inaccuracy of representations and warranties, bankruptcy and insolvency defaults, judgment defaults, change of control defaults, defaults related to the failure to remain registered with the Securities and Exchange Commission and listed for trading on the Nasdaq Stock Market, and any material adverse change. Upon the occurrence and during the continuance of an Event of Default under the Perceptive Credit Agreement, the administrative agent, if requested by the respective lenders, may, among other things, (i) terminate commitments, (ii) declare all outstanding obligations under the agreement (including principal and accrued and unpaid interest) immediately due and payable, and (iii) exercise the other rights and remedies provided for under the agreement. The Perceptive Credit Agreement provides that, under certain circumstances, a default interest rate will apply on all obligations upon the occurrence and during the existence of an Event of Default, at a per annum rate equal to 3% in excess of the applicable interest rate. The Company bifurcated a derivative liability related to the potential acceleration triggered upon an event of default (contingent put option) and the supplemental interest upon an event of default features of the Perceptive Credit Agreement. The fair value of the bifurcated derivative is de minimis to the Company’s consolidated financial statements. Issuance of Warrants In connection with the Company’s initial loan under the Perceptive Credit Agreement, the Company issued Perceptive warrants to purchase up to 1,250,000 shares of its common stock, par value $0.001, with an exercise price of $2.43 per share. Upon the issuance of the delayed draw loan, if applicable, the Company will issue Perceptive warrants to purchase up to 250,000 shares of its common stock, par value $0.001, with an exercise price of equal to the 10-day volume weighted average sale price from the preceding business day. The warrants have a 10 year term and can be exercised by issuing payment to the Company for the number of warrants exercised or exercised net by surrendering warrants with an intrinsic value equal to the cumulative exercise price of the warrants being exercised. The Company determined that these warrants meet the criteria for equity classification and included the proceeds allocated to the warrants, on a relative fair value basis, as a debt discount and additional paid-in capital in the accompanying consolidated financial statements. Debt Issuance Costs In connection with entering into the Perceptive Credit Agreement, the Company incurred debt issuance costs of approximately $1.5 million, comprised primarily of commissions paid to the financial advisor. These costs were allocated to the initial term loan and the currently unissued delayed draw term loan. The costs allocated to the issued term loan are being amortized using the effective interest method over the life of the loan. The costs allocated to the unissued delayed draw term loan have been deferred and will be amortized over the life of the delayed draw term loan starting at the issuance date. If the delayed draw term loan is not issued, the Company will recognize the deferred costs at the point that the Company's rights to borrow on the term loan expires.

Investments, Debt and Equity Securities [Abstract]
CONTRACT ASSETS AND LIABILITIES	CONTRACT ASSETS AND LIABILITIES The Company’s contracts with customers may result in the Company having contract assets and liabilities. These contract assets and liabilities arise primarily from OEM development and supply agreements where the development of the goods does not represent a performance obligation on a standalone basis. The Company defers the development fees billed to customers, and the associated costs, and recognizes them as it completes performance obligations on the supply portion of the agreement. Other contract liabilities may be recognized when a customer prepays for goods or services or if the Company has an unfulfilled performance obligation that a customer has been invoiced for.

Earnings Per Share [Abstract]
EARNINGS (LOSS) PER SHARE	EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share (“basic EPS”) is computed by dividing the net income or loss by the weighted average number of common shares outstanding for the reporting period. Diluted earnings per share (“diluted EPS”) gives effect to all dilutive potential shares outstanding. As the Company is in a net loss position for all periods presented, all potential shares outstanding are anti-dilutive. The following table provides the computation of basic and diluted earnings (loss) per share.

The Company considers the earnings of Apyx Bulgaria, EOOD to be indefinitely invested outside the United States on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs and our specific plans for reinvestment of those subsidiary earnings. It has not recorded a deferred tax liability related to the U.S. Federal and State income taxes and foreign withholding taxes on the undistributed earnings of Apyx Bulgaria, EOOD indefinitely invested outside the United States. If it decides to repatriate the foreign earnings, the Company will need to adjust its income tax provision in the period it determines that the earnings will no longer be indefinitely invested outside the United States. The Company assesses the financial statement impact of an uncertain tax position taken or expected to be taken on an income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized in the financial statements unless it is more likely than not of being sustained. As of December 31, 2023, the Company has no uncertain tax positions. As of December 31, 2022, the Company had recorded a liability of approximately $1.3 million related to uncertain tax positions and accrued approximately $0.8 million and of interest and penalties on these positions.

COMMITMENTS AND CONTINGENCIES	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Litigation The medical device industry is characterized by frequent claims and litigation, and the Company may become subject to various claims, lawsuits and proceedings in the ordinary course of our business. Such claims may include claims by current or former employees, distributors and competitors, claims concerning the marketing and promotion of our products and product liability claims. The Company is involved in a number of legal actions relating to the use of our Helium Plasma technology. The outcomes of these legal actions are not within the Company’s control and may not be known for prolonged periods of time. It believes that such claims are adequately covered by insurance; however, in the case of one of the Company’s carriers, the Company is in a dispute regarding the total level of coverage available. Notwithstanding the foregoing, in the opinion of management, the Company has meritorious defenses, and such claims are not expected, individually or in the aggregate, to result in a material, adverse effect on its financial condition, results of operations and cash flows. However, in the event that damages exceed the aggregate coverage limits of the Company’s policies or if its insurance carriers disclaim coverage, management believes it is possible that costs associated with these claims could have a material adverse impact on the consolidated financial condition, results of operations and cash flows. During December 2021, the Company provided notice of contract termination to an international distributor of the Company. In March 2022, the Company received a letter from the former distributor citing improper contract termination and alleging damages. During 2022, the Company recorded an estimated loss of $250,000 in professional services in the Consolidated Statement of Operations for the year ended December 31, 2022. The Company has not experienced any movement on the matter since our response to the distributor in the fourth quarter of 2022. Accordingly, management revised its estimated loss on the matter to $0 as it is no longer probable that a loss has been incurred. The reduction in estimated loss of $250,000 is included in professional services in the accompanying Consolidated Statement of Operations for the year ended December 31, 2023. As previously disclosed with the U.S. Securities and Exchange Commission on the Company’s Current Report on Form 8-K filed June 7, 2022, on June 6, 2022, a complaint (the “Hattaway Complaint”) was filed in the United States District Court for the Middle District of Florida (the “U.S. District Court”) by plaintiff William E. Hattaway, individually and on behalf of all others similarly situated against the Company, Charles D. Goodwin (“Goodwin”), the Company’s President and Chief Executive Officer and a member of the Company’s Board of Directors, and Tara Semb (“Semb”), the Company’s Chief Financial Officer, Treasurer and Secretary, alleging violations by the Company, Goodwin and Semb of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, primarily related to certain public statements and disclosures concerning the off-label usage of certain of the Company’s Advanced Energy products and the impact such usage would have on the Company’s business, operations and prospects. The Hattaway Complaint sought an unspecified amount of damages. While the matter was in the early stages, management had determined that a loss was probable in the estimated range of $475,000 to $2,500,000. The Company recorded an estimated loss of $475,000 in professional services in the accompanying Consolidated Statement of Operations for the year ended December 31, 2022. On June 15, 2023, the U.S. District Court issued an Order dismissing the Hattaway Complaint and granting plaintiff until July 3, 2023 to file a second amended complaint, failing which the U.S. District Court would close the case. On June 27, 2023, the Plaintiff formally notified the Court that a Second Amended Complaint will not be filed and on July 17, 2023, the case was marked closed based on the Court’s June 15, 2023 dismissal order. This closed the matter for the estimated loss recorded by the Company. During 2022, the Company was notified of certain procedures alleged to have been performed by the same physician and which are currently the subject of two related products liability cases within the courts. During 2023, the Company was notified by its insurance carriers that all or most of the ten individual plaintiff’s allegations could be subject to separate deductibles notwithstanding the commonality of each underlying occurrence. During March 2024, two of the plaintiffs claims were dismissed by the courts. The Company has determined that a loss, comprised of estimated costs to defend the Company against the lawsuits, is probable and that the range of estimated losses is approximately $1,450,000 to $1,950,000. The Company recorded an estimated loss of $1,450,000 related to the matters during 2022. It is at least possible that a change in the actual amount of loss will occur in the near term, though management expects the actual amount of loss will be within the estimated range of losses. On March 1, 2023, Shiva Stein as plaintiff filed a derivative complaint in the Court of Chancery of the State of Delaware, captioned Stein v. Makrides, et al., C.A. No. 2023-0239-MTZ (the “Stein Suit”) against individual members of the Company’s board of directors and naming the Company as a nominal defendant, primarily concerning the facts at issue in a previously disclosed federal securities class action lawsuit filed in 2019 and settled in 2020, captioned Pritchard v. Apyx Medical Corporation, et al., Case No. 8:19-cv-00919 (M.D. Fla.) (the “Pritchard Case”). The Stein Suit sought unspecified damages alleged to have resulted from purported breaches of fiduciary duty, unjust enrichment and related claims based on the same set of allegedly misleading statements and material omissions described in the settled Pritchard Case, which concerned the 2018-2019 clinical study conducted by the Company to evaluate the safety and efficacy of its J-Plasma technology for dermal resurfacing. On April 3, 2023, the Company formally moved to dismiss the case as time-barred and on other legal grounds, which triggered the plaintiff’s right to file an amended complaint. On July 12, 2023, plaintiff’s counsel informed the Company’s counsel that plaintiff Stein did not intend to file an amended complaint, and on July 17, 2023 plaintiff’s counsel filed a notice of voluntary dismissal. An order of the Court dismissing the Stein Suit, with prejudice, was entered on July 20, 2023. During March 2024, the Company was named as a defendant in a number of product liability lawsuits filed under the direction of a single plaintiff’s tort firm in connection with off-label use of Renuvion products and the Company’s alleged mismarketing of the same. The suits are based predominantly in Florida and nearly all involve procedures conducted prior to 2023, which was before the Company received FDA 510k clearance for the use of Renuvion in the types of procedures at issue. The Company denies liability and intends vigorously to defend these suits, many of which appear to be stale under relevant statutes of limitations, in addition to what other substantive defenses may be determined to apply. The Company has determined that a loss, comprised of estimated costs to defend the Company against the lawsuits, is probable and currently estimates the range of losses in connection with these matters to be between $1,300,000 and $1,500,000. The Company recorded an estimated loss of $1,300,000 related to these matters in the accompanying Consolidated Statement of Operations for the year ended December 31, 2023. The Company has also determined that there is a reasonable possibility that there will be an additional loss related to the matters, but the Company is unable to provide an estimate of the range of such additional loss at this time. Purchase Commitments At December 31, 2023, the Company has purchase commitments for inventories totaling approximately $3.8 million, all of which is expected to be purchased by the end of 2024. Concentrations There were no significant sales concentrations for the years ended December 31, 2023 and 2022. Receivables from two customers and one customer within the Advanced Energy segment represented 22% and 13%, respectively, of trade accounts receivable at December 31, 2023 and 2022.

All options granted were pursuant to the plans noted above. The options ves t over a period of three years. The status of the Company’s stock options is summarized as follows: Number of options Weighted average exercise price Outstanding at December 31, 2021 5,397,691 $ 5.95 Granted 1,692,417 10.64 Exercised (316,506) 3.96 Canceled and forfeited (253,158) 9.59 Outstanding at December 31, 2022 6,520,444 $ 7.12 Granted 1,527,865 2.63 Exercised (57,000) 2.65 Canceled and forfeited (648,426) 6.18 Outstanding at December 31, 2023 7,342,883 $ 6.31 Number of options Weighted average grant date fair value Non-vested at December 31, 2022 2,227,608 $ 6.27 Granted 1,527,865 1.95 Vested (1,195,115) 5.78 Forfeited (504,577) 4.00 Non-vested at December 31, 2023 2,055,781 $ 3.90 Common shares required to be issued upon the exercise of stock options would be issued from authorized and unissued shares. Options are valued using the Black-Scholes model. For employee grants, the Company calculates expected life via the simplified method as it does not have sufficient history to determine actual expected life. For non-employee grants, the Company calculates expected life using a combination of past exercise behavior, the contractual term and expected remaining exercise behavior. Inputs used in the valuation models are as follows: 2023 Grants 2022 Grants Exercise price $2.50 - $4.21 $5.10 - $10.96 Risk-free rate 3.6% - 4.3% 1.6% - 3.9% Expected dividend yield —% —% Expected volatility 85.8% - 88.4% 69.6% - 78.5% Expected term (in years) 6 5 - 6 The Company recognized approximately $5,114,000 and $6,697,000 in stock-based compensation expense during the years ended December 31, 2023 and 2022, respectively. The intrinsic value of each option share is the difference between the fair value of our common stock and the exercise price of such option share to the extent it is “in-the-money”. Aggregate intrinsic value represents the value that would have been received by the holders of in-the-money options had they exercised their options on the last trading day of the year and sold the underlying shares at the closing stock price on such day. The intrinsic value calculation at December 31, 2023 is based on the $2.62 closing stock price of the Company's common stock on December 29, 2023, the last trading day of 2023. As of December 31, 2023, there were 6,931,726 stock options outstanding and expected to vest with an aggregate intrinsic value of approximately $140,000. These options have a weighted average exercise price of $6.33 and a weighted average remaining contractual term of approximately 6 years. As of December 31, 2023, there were 5,287,102 stock options outstanding and exercisable with an aggregate intrinsic value of approximately $140,000. These options have a weighted average exercise price of $6.43 and a weighted average remaining contractual term of approximately 6 years. The total intrinsic value of in the money options exercised during the years ended December 31, 2023 and 2022, was approximately $210,000 and $900,000, respectively. Intrinsic value of exercised shares is the fair value of such shares on the date of exercise less the exercise price of the option on the exercise date. The total fair value of options granted during the years ended December 31, 2023 and 2022, was approximately $2,980,000 and $11,350,000, respectively. The weighted average fair value of options granted during the years ended December 31, 2023 and 2022, was $1.95 and $6.71, respectively. The total fair value of options vested during the years ended December 31, 2023 and 2022, was approximately $6,900,000 and $5,260,000, respectively. The Company allows employees to exercise stock-based awards by surrendering stock-based awards with an intrinsic value equal to the cumulative exercise price of the stock-based awards being exercised, referred to as net settlements. These surrenders are included in stock options exercised in the options rollforward above. During the years ended December 31, 2023 and 2022, the Company received 10,967 and 125,596 options as payment in the exercise of 11,033 and 81,737 options, respectively. As of December 31, 2023, there was approximately $4,280,000 of total unrecognized stock-based compensation expense, related to unvested stock options granted under the plans above. This expense is expected to be recognized over a weighted-average period of approximately 1 year.

Segment Reporting [Abstract]
GEOGRAPHIC AND SEGMENT INFORMATION	GEOGRAPHIC AND SEGMENT INFORMATION Operating segments are aggregated into reportable segments only if they exhibit similar economic characteristics. In addition to similar economic characteristics, the Company also considers the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to its chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors. Asset information is not reviewed by the chief operating decision maker by segment and is not available by segment, accordingly, the Company has not presented a measure of assets by segment. The Company’s reportable segments are disclosed as principally organized and managed as two operating segments: Advanced Energy and OEM. "Corporate & Other" includes certain unallocated corporate and administrative costs which were not specifically attributed to any reportable segment. The OEM segment is primarily development and manufacturing contract and product driven, all related expenses are recorded as cost of sales, therefore no segment specific operating expenses are incurred. Summarized financial information with respect to reportable segments is as follows: Year Ended December 31, 2023 (In thousands) Advanced Energy OEM Corporate (Other) Total Sales $ 43,382 $ 8,967 $ — 52,349 (Loss) income from operations (360) 2,524 (19,423) (17,259) Interest income — — 921 921 Interest expense — — (2,478) (2,478) Other income, net — — 622 622 Loss on extinguishment of debt — — (3,088) (3,088) Income tax benefit — — (2,432) (2,432) Year ended December 31, 2022 (In thousands) Advanced Energy OEM Corporate (Other) Total Sales $ 36,803 $ 7,707 $ — $ 44,510 (Loss) income from operations (4,103) 1,641 (21,100) (23,562) Interest income — — 157 157 Interest expense — — (15) (15) Other income, net — — 509 509 Income tax expense — — 367 367 International sales in 2023 and 2022, were 26.8% and 29.9% of sales, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidated Financial Statements	Consolidated Financial Statements
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. The reported amounts of revenues and expenses during the reporting period may be affected by the estimates and assumptions the Company is required to make.
Cash and Cash Equivalents	Cash and Cash Equivalents
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of trade accounts receivable. With respect to cash, the Company frequently maintains cash and cash equivalent balances in excess of federally insured limits. However, it has not experienced any losses in such accounts.
Trade Accounts Receivable and Allowance for Credit Losses	Trade Accounts Receivable and Allowance for Credit Losses The Company’s standard credit terms for billings range from net 30 days to net 120 days, depending on the customer agreement. However, management is able to use discretion in actual terms granted to customers. Accounts receivable are determined to be past due if payments are not made in accordance with such agreements.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first in, first out basis. Finished goods and work-in-process inventories include material, labor and overhead costs. Factory overhead costs are allocated to manufactured inventory based upon labor hours. The Company monitors inventory usage to determine if the carrying value of any items should be adjusted due to lack of demand for the item and adjusts inventory for estimated obsolescence or unusable inventory equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. Depreciation and amortization are provided for using the straight-line method over the estimated useful lives of the assets. The amortization of leasehold improvements is based on the shorter of the lease term or the life of the improvement. Betterments and major improvements, which extend the life of the asset, are capitalized, whereas maintenance and repairs and routine improvements are expensed as incurred. The estimated useful lives are: buildings and improvements, 39 years; machinery and equipment, 3-10 years; furniture and fixtures, 5-10 years; computer equipment and software, 3-5 years; and molds, 7-15 years.
Valuation of Long-Lived Assets	Valuation of Long-Lived Assets The Company reviews long-lived assets for recoverability if events or changes in circumstances indicate that the assets may have been impaired. This circumstance exists when the carrying amount of the asset exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. In those cases, an impairment loss is recognized to the extent that the assets’ carrying amount exceeds its fair value. Any impairment losses are not restored in the future if the fair value increases. At December 31, 2023 and 2022, the Company believes the remaining carrying values of its long-lived assets are recoverable.
Leases	Leases The Company does not recognize leases with terms less than twelve months in duration, or that have variable only payments, in its Consolidated Balance Sheets as right-of-use assets and lease liabilities. The Company has adopted the practical expedient which allows for the Company to not separate lease and non-lease components of contracts. Accordingly, non-lease components are included in the measurement of the Company’s lease liabilities and right-of-use assets. If the Company is aware of the implicit rate in leases, the Company determines the operating lease liability using the implicit rate. For those leases where the Company is not aware of the implicit rate in the lease, the Company utilizes an incremental borrowing rate, which is indicative of its collateralized borrowing rate. Rates utilized were 1.83% to 9.09% for our outstanding leases at December 31, 2023.
Product Warranties	Product Warranties The Company provides a four-year limited warranty on end-user sales of its Renuvion and J-Plasma generators, a two year warranty on mounting fixtures, and a one-year warranty on certain accessories. The Company estimates and provides for future costs for product warranties in cost of sales at the time revenue is recognized. The Company bases its product warranty costs on related material costs, repair labor costs and shipping costs. The Company estimates the future cost of product warranties by considering historical material, repair labor, and shipping costs, and applying the experience rates to the outstanding warranty period for products sold. It is reasonably possible that actual results could differ from those estimates.
Debt and Debt Issuance Costs	Debt and Debt Issuance Costs Proceeds allocated to debt instruments are recorded net of discounts, such as those resulting from other financial instruments issued in a debt transaction or bifurcated embedded derivative features within the debt agreement, and debt issuance costs. Debt issuance costs are allocated to issued and unissued financial instruments based on costs incurred and the underlying commitments in the debt agreement. At the inception of the debt instrument, the Company determined the fair value of the debt and other financial instruments, including warrants and bifurcated embedded derivatives, and allocated the proceeds to each financial instrument based upon these estimated fair values. Debt issuance costs allocated to unissued financial instruments are deferred as an asset until the financial instrument is issued. Debt discounts and issuance costs are amortized over the estimated life of issued debt using the effective interest method and are presented as reduction of the related debt.
Revenue Recognition	Revenue Recognition Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that the Company expects to receive for those goods or services. To recognize revenue, the Company (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when, or as, it satisfies the performance obligation(s). For sales of the Company's Advanced Energy products (Renuvion and J-Plasma), this is at a point in time when title has been transferred to the customer, which is generally at the time of shipment or receipt by customer for FOB destination terms. For sales of products under its OEM agreements, the Company recognizes revenue over time when no alternative use exists for the manufactured goods and the Company has rights to payment. Presently, the Company does not stock any significant completed goods under its OEM agreements, accordingly, the recognition of revenue under these agreements approximates point in time recognition. The following policies apply to its major categories of revenue transactions: • The majority of sales to customers are evidenced by firm purchase orders. Generally, title and the risks and rewards of ownership are transferred to the customer when the product is shipped. Payment by the customer is due under fixed payment terms. • Product returns are only accepted at the Company's discretion and in accordance with its “Returned Goods Policy”. Historically, the level of product returns has not been significant. Accruals for sales returns, rebates and allowances are made as a reduction of revenue based upon an analysis of historical customer returns and credits, rebates, discounts and current market conditions. • The terms of sale to customers generally do not include any obligations to perform future services. Limited warranties are generally provided for sales and provisions for warranty are provided at the time of product sale based upon an analysis of historical data. •
Advertising Costs	Advertising Costs
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, Compensation-Stock Compensation . FASB ASC 718 requires recognizing compensation expense for all share-based payment awards made to employees, directors and non-employees based upon the grant date fair value of such awards. It accounts for forfeitures as they occur. The standard covers employee stock options, restricted stock and other equity awards. The Company utilizes a Black-Scholes model to estimate the grant date fair value of stock option awards. For employee and director awards, compensation expense is recognized on a straight-line basis over the vesting periods. For non-employee awards, compensation expense is recorded for non-forfeitable, fully vested awards at the grant date. For other awards granted to non-employees, compensation cost is recognized as services are provided, which approximates a straight-line basis over the vesting period.
Litigation Contingencies	Litigation Contingencies In accordance with authoritative guidance, the Company accrues a liability in its consolidated financial statements when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible, but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed in the notes to the consolidated financial statements. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded; actual results may differ from those estimates.
Earning s(Loss) Per Share	Earnings (Loss) Per Share The Company computes basic (loss) earnings attributable to common stockholders per share by dividing net (loss) income attributable to common stockholders by the weighted average number of common shares outstanding for the reporting period. Diluted (loss) earnings per share attributable to common stockholders gives effect to all potential dilutive shares outstanding during the period. The number of dilutive shares is calculated using the treasury stock method which reduces the effective number of shares by the amount of shares the Company could purchase with the proceeds of assumed exercises. Anti-dilutive units are excluded from the calculation of diluted shares. In periods of loss, all potentially dilutive units are anti-dilutive and are excluded from the calculation of diluted income (loss) per share.
Research and Development Costs	Research and Development Costs
Income Taxes	Income Taxes The Company utilizes the liability method of accounting for income taxes as set forth in FASB ASC Topic 740, Income Taxes . Under the liability method, deferred taxes are determined based on temporary differences between the financial statement and tax bases of assets and liabilities using tax rates expected to be in effect during the years in which the deferred taxes reverse. The Company accounts for interest and penalties on income taxes as income tax expense. A valuation allowance is recorded when it is more likely than not that a tax benefit will not be realized. In determining the need for valuation allowances the Company considers projected future taxable income, the timing of reversals of temporary differences, and the availability of tax planning strategies. As of December 31, 2023 and 2022, the Company recorded a valuation allowance on its net deferred tax assets. The Company assesses the realizability of deferred tax assets each reporting period and will be able to reduce the valuation allowance to the extent the financial results of continuing operations improve, and it becomes more likely than not that the deferred tax assets will be realized. As Management has not fully determined the timing of when it will generate taxable income in the U.S., the Company will continue to record a full valuation allowance on the net deferred tax assets as of December 31, 2023.

Reclassifications	Reclassifications The Company has reclassified certain amounts presented in the prior year to conform to the current year presentation. These reclassifications had no impact on previously reported net income, retained earnings or operating cash flows for the periods presented.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). The update changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, contract assets, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update, as originally issued, was effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) Effective Dates , which deferred the effective dates of these standards for Smaller Reporting Companies until fiscal years beginning after December 15, 2022. The Company adopted ASU 2016-13 on January 1, 2023, and its impact was not material to the Company. No other new accounting pronouncement issued or effective during the fiscal year had or is expected to have a material impact on the Company's consolidated financial statements or disclosures.
