RECRUITING

PHASE4

Treatment of Perioral Wrinkles Using Topical Poly-L-lactic Acid and Microneedling Device

Sponsor: Skincare Physicians of Chestnut Hill

View on ClinicalTrials.gov

Summary

The first goal of this clinical trial is to learn if topical application of PLLA in conjunction with a microneedling treatment works to treat perioral wrinkles in adults. The second goal is to see whether the application of topical PLLA is more effective before or after a microneedling treatment. The main questions it aims to answer are: * Is PLLA present within the MN channels from in vivo biopsy samples? * Is it safe to combine topical PLLA and MN in the treatment of perioral wrinkles, as determined by the incidence and severity of adverse events in healthy subjects? * Does overall aesthetic and skin texture improve in combining microneedling with topical PLLA in the treatment of mild to moderate perioral wrinkles? * Is it the treatment of topical PLLA more effective when applied before or after a microneedling treatment. Researchers will compare the application of PLLA before a microneedling treatment to a microneedling treatment with PLLA application after to see which treatment method is more effective. Participants will: \- receive 2 treatments spaced 4-6 weeks apart of topical PLLA and microneedling
