PG - 1215-1219 LID - 10.1097/DSS.0000000000003602 [doi] AB - BACKGROUND: Pigmented lesions from chronic UV photoaging are extremely common on the face and hands. OBJECTIVE: To evaluate the safety and efficacy of a 532-nm picosecond laser for these types of pigmented lesions. METHODS: This was a single-center, prospective, open-label clinical trial. Eligible subjects with pigmentation on the face and hands received 3 monthly treatments, with 1 month (1M) and 3 months (3M) follow-up. Change in investigator-graded overall facial and per lesion pigmentation and subject-graded satisfaction and pigmentation improvement was evaluated by a 5-point scale. Immediate skin response and adverse events (AEs) were evaluated post-treatment. The melanin index was measured using a mexameter. Randomized before and after photographs were graded by 3 blinded physicians for degree of pigmentation improvement. RESULTS: Twenty-five subjects (22F/3M) with Fitzpatrick skin types I-III were enrolled, with 23 subjects completing. Treatments used a 532 nm wavelength, 800 ps pulse duration, 4-6mm spot size, and 0.1 to 0.6J/cm2 fluence. Good-to-excellent clearance at 1M/3M was demonstrated in >/=95% of lesions (n = 116). Only mild treatment-related pain was reported, with transient post-treatment AEs (mean downtime of 2.1 +/- 2.0 days) and no serious treatment-related AEs. Subject satisfaction (satisfied or very satisfied) was 95% at 1M and 91% at 3M. CONCLUSION: Treatment with a 532-nm picosecond laser is safe and highly effective for the treatment of the pigmented lesions of the face and dorsal hands.
