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

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

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
