Safety and Efficacy of a 2,910 nm Fractional Ablative Fiber Laser (UltraClear®) for Improvements of Skin Laxity and Lifting of the Lower Face, Submental, and Neck Treatment Areas (UC 29-2026)

9 agosto 2026 aggiornato da: FA Corporation
This study evaluates the safety and effectiveness of the UltraClear® 2,910 nm fractional ablative fiber laser for improving skin laxity and tissue lifting in the lower face, submental, and neck areas. Up to 50 adults ages 35-65 will receive two laser treatments approximately 7 weeks apart at two clinical sites. Outcomes will be assessed approximately 90 days after the second treatment using photographic analysis and investigator- and participant-reported improvement scales.

Intervento / Trattamento
Sperimentale: 2910 nm fiber laser treatment
Participants receive two treatments with the UltraClear® 2,910 nm fractional ablative fiber laser to the lower face, submental region, and neck, spaced approximately 7 weeks (±7 days) apart.
UltraClear® is a 2,910 nm fractional ablative erbium-doped fluoride glass fiber laser (Acclaro), FDA 510(k) cleared (K210847, K233803) for dermatological procedures requiring coagulation, resurfacing, and ablation of soft tissue. In this study, it is applied to the lower face, submental region, and neck using fractional ablative resurfacing, laser-coring, and full ablative resurfacing configurations, with mode and parameters selected by the investigator based on baseline anatomy and tissue laxity.

Lasso di tempo
Incidence of Treatment Emergent Adverse Events and Discomfort Scores (Safety and Tolerability)
Lasso di tempo: Through the study, an average of 1 year

Participant-rated discomfort via visual analog scale (VAS) will be completed following each 2910 nm fiber laser treatment. Range: 0-10 Directionality: lower score equates to less discomfort (ie. 0= No pain, 5= Moderate Pain, 10 = Worst Pain).
