| Adjustment to Non-PEO NEO Compensation Footnote [Text Block] | The dollar amounts reported in column (e) represent the average amount of “compensation actually paid” to the NEOs as a group (excluding Mr. Foley), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Mr. Foley) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total reported compensation for the NEOs as a group (excluding Mr. Foley) for each year to determine the compensation actually paid, using the same methodology described above in Note 2: Year Average Average Average Equity Award Adjustments(a) Average Compensation Actually Paid to Non-PEO NEOs 2022 $ 2,600,645 - $ 1,837,926 + $ 2,461,551 = $ 3,224,270 2021 $ 2,833,814 - $ 2,076,405 + $ (775,782) = $ (18,373) 2020 $ 2,878,149 - $ 2,548,683 + $ 4,470,631 = $ 4,800,096 (a) The amounts deducted or added in calculating the total average equity award adjustments are as follows: Year Year End Fair Value of Current Year Awards Outstanding as of Year End Fair Value as of Year End for Prior Year Awards Outstanding as of Year End Fair Value as of Vesting Date for Prior Year Awards That Vested During the Year Fair Value as of Vesting Date for Current Year Awards That Vested During the Year Fair Value as of Vesting Date for Dividend Equivalents That Vested During the Year Fair Value as of Prior Year End for Prior Year Awards Total Fair Value of Equity Adjustments (i) 2022 $ 1,682,090 + $ 1,662,709 + $ 827,587 + $ 127,072 + $ — - $ 1,837,907 = $ 2,461,551 2021 $ 667,840 + $ 1,032,726 + $ 1,118,026 + $ 101,474 + $ — - $ 3,695,848 = $ (775,782) 2020 $ 3,188,804 + $ 870,537 + $ 532,383 + $ 650,426 + $ — - $ 771,518 = $ 4,470,631 (i) Total Equity Award Adjustments value may differ from amount reported in the table under Footnote 4 above due to rounding. | | |
| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Compensation Actually Paid and Cumulative TSR As demonstrated by the following graph, the amount of compensation actually paid to Mr. Foley and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Foley) is aligned with the Company’s cumulative TSR over the three years presented in the table. The alignment of compensation actually paid with the Company’s cumulative TSR over the period presented is because a significant portion of the compensation actually paid to Mr. Foley and to the other NEOs is comprised of equity awards. As described in more detail in the section “ Executive Compensation — Compensation Discussion and Analysis ,” the Company generally structures a significant portion of target compensation granted to the NEOs to be comprised of equity awards, including time-vesting stock awards, option awards and performance-vesting stock awards. | | |
| Compensation Actually Paid vs. Net Income [Text Block] | Compensation Actually Paid and Net Income (Loss) Although we received DAXXIFY ® GL Approval, we expect to continue to incur losses for the foreseeable future. Consequently, we did not use net income (loss) as a performance measure in our executive compensation program. Moreover, as an early commercial stage company with a limited history of product revenue associated with DAXXIFY ® , the RHA ® Collection of dermal fillers and the Fintech Platform, we do not believe there is any meaningful relationship between our net loss and compensation actually paid to our NEOs during the periods presented. | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | Compensation Actually Paid and Revenue While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Product and Service Revenue is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to Company performance. The following graph demonstrates, the amount of compensation actually paid to Mr. Foley and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Foley) in comparison with the Company’s Product and Service Revenue over the three years presented in the table. | | |
| Total Shareholder Return Vs Peer Group [Text Block] | Cumulative TSR of the Company and Cumulative TSR of the Peer Group As demonstrated by the following graph, the Company’s cumulative TSR over the three year period presented in the table was 14%, while the cumulative TSR of the peer group presented for this purpose, the NASDAQ Biotechnology Index, was 11% over the three years presented in the table. For more information regarding the Company’s performance and the companies that the Compensation Committee considers when determining compensation, refer to “ Executive Compensation — Compensation Discussion and Analysis .” | | |

| Additional 402(v) Disclosure [Text Block] | Total Equity Award Adjustments value may differ from amount reported in the table under Footnote 2 above due to rounding. The fair values of stock options vested during the fiscal year or outstanding as of fiscal year end were estimated using the Black-Scholes option pricing model with the following assumptions, which are materially different from the assumptions used for estimating the grant-date fair value as reported in the “Option Awards” columns in the Summary Compensation Table: Year Ended December 31, 2022 2021 2020 Expected term (in years) 2.2 – 6.7 3.6– 6.4 3.6 – 6.1 Expected volatility 60.1 - 72.9% 54.2 – 64.1% 56.9 – 63.4% Risk-free interest rate 1.1 – 4.6% 0.3 – 1.4% 0.2 – 1.7% Expected dividend rate — % — % — % The dollar amounts reported represent the amount of net loss reflected in the Company’s audited financial statements for the applicable year. Although we received DAXXIFY ® GL Approval, we expect to continue to incur losses for the foreseeable future. Consequently, the Company did not use net income (loss) as a performance measure in its executive compensation program. Analysis of the Information Presented in the Pay Versus Performance Table As described in more detail in the section “ Executive Compensation — Compensation Discussion and Analysis ,” the Company’s executive compensation program reflects a pay-for-performance philosophy that emphasizes variable pay opportunities based on performance goals and stockholder value. The Company generally seeks to incentivize long-term performance, and has not specifically aligned Company performance measures with “compensation actually paid”, as computed in accordance with Item 402(v) of Regulation S-K, for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table. | | |
