In Vivo Study to Evaluate Tissue Remodeling Via Fibroblast Stimulation Following a Single SofWave Treatment

In Vivo Study to Evaluate Tissue Remodeling Via Fibroblast Stimulation Following a Single SofWave Treatment

Open-label, non-randomized single-arm prospective, single-center, self-controlled clinical study.

Eligible subjects will arrive for a screening visit, and if will be found eligible and will provide signed ICF, during this visit a biopsy will be taken from the pre-auricular area.

At the second visit, a week after the screening visit, sutures from the biopsy (if present) will be removed, and subjects will receive a single treatment on the full face, neck, and submental area using the SofWave system with the Lift applicator.

Subjects will return to the clinic for a follow-up visit at one of the following timepoints (2 subjects per timepoint): 5 days, 4 weeks ± 2 days, 8 weeks ± 2 days, 12 weeks ± 4 days, or 24 weeks ± 4 days post-treatment. During this visit, an additional biopsy will be taken from the opposite pre-auricular side to that used at the screening visit.

All subjects will arrive for an additional visit, a week after the follow-up visit, for suture removal (if will exist).
