Safety and Efficacy of Matrix Pro for Eyebrow Lift and Lift of Submental/Neck Laxity

This is a two-arm study. Eligible participants will receive up to three treatments with the Matrix Pro Applicator for lifting the eyebrow and/or improving lax tissue in the submental and neck areas. Treatments will be spaced approximately 6 weeks apart (± 2 weeks), and all participants will undergo follow-up evaluations at 1 month (± 2 weeks) and 3 months (± 2 weeks) after the final treatment.

Each investigational site will treat two areas: In arm 1, the upper face, including the forehead and peri-orbital area, to lift the eyebrows. In arm 2, the lower face, including the submental and neck areas, to lift lax tissue. Each patient could be assigned to both arms. Treatment may occur immediately after the screening and enrollment visit or at a later date, depending on site scheduling. Additional follow-up visits may be required at the investigator's discretion.
