Commitments and Contingencies [Abstract]
Commitments and Contingencies	11. Commitments and Contingencies Legal Matters In the ordinary course of business, the Company is routinely a defendant in or party to pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings are generally based on alleged violations of employment, contract, and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Company. In the ordinary course of business, the Company is also subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations, and threatened legal actions and proceedings. In connection with formal and informal inquiries by federal, state, local and foreign agencies, the Company receives numerous requests, subpoenas and orders for documents, testimony, and information in connection with various aspects of its activities. Accrued State Sales and Use Tax Matters The Company records state sales tax collected and remitted for its customers on dermatology procedures equipment sales on a net basis, excluded from revenue. The Company’s sales tax expense that is not presently being collected and remitted for the recurring revenue business is recorded in general and administrative expenses within the consolidated statements of operations. The Company believes its state sales and use tax accruals have been properly recognized such that, if the Company’s arrangements with customers are deemed more likely than not that the Company would not be exempt from sales tax in a particular state, the basis for measurement of the state sales and use tax is calculated in accordance with ASC 405, Liabilities, as a transaction tax. If and when the Company is successful in defending itself or in settling the sales tax obligation for a lesser amount, the reversal of this liability is to be recorded in the period the settlement is reached. In the ordinary course of business, the Company is, from time to time, subject to audits performed by state taxing authorities. These actions and proceedings are generally based on the position that the arrangements entered into by the Company are subject to sales and use tax rather than exempt from tax under applicable law. The Company has outstanding assessments from the states of New York and California aggregating to $5.6 million including penalties and interest. The audits cover the period from August 2017 through February 2025. In January 2021, the Company received notification that an administrative state judge in New York issued an opinion finding in favor of the Company that the sale of XTRAC treatment codes was not taxable as sales tax with respect to that state’s first assessment. The relevant taxing authority filed an appeal of the administrative law judge’s finding and, following the submission of legal briefs by both sides and oral argument held in January 2022, on May 6, 2022, the Company received a written decision from the Tribunal overturning the favorable sales tax determination of the administrative law judge. The Company appealed the Tribunal’s decision to the New York State Appellate Division (“Appellate Division”), and posted the required appellate bond in the form of cash collateral in the amount of $1.3 million. Oral argument was held by the Appellate Division on January 18, 2024. On March 8, 2024, the Company received a decision from the Appellate Division ruling against it in the matter of its sales tax appeal, affirming the Tribunal’s ruling that the Company’s sale of XTRAC treatment codes is subject to sales tax. The Appellate Division concluded that, through the usage arrangements, the Company’s customers had possession of the laser devices and had a license and ability to use the laser devices. The Appellate Division also agreed with the Tribunal that the primary function analysis was not applicable in this matter. On April 11, 2024, the Company filed a motion for leave to appeal the Appellate Division’s decision to the New York State Court of Appeals (“Court of Appeals”). On October 22, 2024, in an unsigned one-line decision, the Court of Appeals denied the Company’s motion to appeal the Appellate Division ruling. Therefore, the adverse decision stands and New York executed on the appellate bond the Company posted for $1.3 million. As of December 31, 2025, the Company has a remaining accrual of $0.6 million including penalties and interest as a result of the Appellate Division ruling. The Company is in the administrative process of appeal with respect to the remaining $2.6 million of assessments in the state of New York. The Company believes that the Appellate Division ruling provides an avenue for challenging the pending audit periods and subsequent periods, provided the Company can show that the value of the equipment provided to customers is incidental to the overall value of the non-taxable services that are provided, or should be treated similarly to pharmaceutical treatments, which are generally exempt from sales tax. The state of California has made aggregate assessments of $2.4 million including penalties and interest. The audits cover the period from June 2018 through June 2022. The Company is in the administrative process of appeal in this jurisdiction as well. In those states where the Company did not or may not prevail with the defenses it has proposed, and in the event there is a determination that the true object of the Company’s recurring revenue model is not exempt from sales taxes and is not a prescription medicine, or the Company does not have other defenses where the Company prevails, the Company may be subject to sales taxes in those particular states for previous years and in the future, plus potential interest and penalties. The precise scope, timing and time periods at issue, as well as the final outcomes of the investigations and judicial proceedings, remain uncertain. Accordingly, the Company’s estimate may change from time to time, and actual losses could vary. Employee 401(k) Savings Plan The Company sponsors a 401(k) defined contribution retirement savings plan that covers all eligible employees who have met the minimum age and service requirements. Under the plan, eligible employees may contribute a portion of their annual compensation into the plan up to IRS annual limits. The Company has elected to make matching contributions to the plan based on a percentage of the employee’s contribution. For each of the years ended December 31, 2025 and 2024, the Company’s contributions to the plan were $0.3 million. Contingent Consideration In connection with the Company’s acquisition of certain assets related to the TheraClear devices, Theravant was eligible to receive up to $3.0 million in future earnout payments upon the achievement of certain annual net revenue milestones ($1.0 million of which was due upon the earlier of achieving a revenue target or July 2025), up to $20.0 million in future royalty payments based upon a percentage of gross profit from future domestic sales ranging from 10-20%, 25% of gross profit from international sales over the subsequent four-year period, and up to $0.5 million in future milestone payments upon the achievement of certain commercialization related targets. Pursuant to the Theravant Settlement executed in October 2025 (see Note 8), the Company was released from all obligations related to contingent consideration. Royalty Payments As additional consideration to the mutual releases contained within the Theravant Settlement, the Company will owe Theravant a royalty equal to 5% of sales of TheraClear® X devices, payable quarterly in arrears, starting on the later of January 1, 2027 or when the Company first achieves annual domestic revenue of more than $2.5 million from the sale or placement of TheraClear® X devices and ending on the first to occur of (i) the Company has paid aggregate royalties of $3.0 million to Theravant or (ii) the Company commercially launches a new TheraClear® X device and replaces the current TheraClear® X device (as defined in the Theravant Settlement). No royalties were incurred or considered probable of being incurred through December 31, 2025.

The Company believes its state sales and use tax accruals have been properly recognized such that, if the Company’s arrangements with customers are deemed more likely than not that the Company would not be exempt from sales tax in a particular state, the basis for measurement of the state sales and use tax is calculated in accordance with ASC 405, Liabilities, as a transaction tax.
