xloma.fota13 shared this article with you from Inoreader Treatment of pigmentary disorders using picosecond laser in Asian patients: a meta‐analysis and systematic review Via Dermatologic Therapy ABSTRACT Purpose There were many studies evaluating the effect of picosecond (PS) lasers, but no meta‐analysis examined the effects of PS laser in the treatment of pigmentary disorders in Asians. The aim of this article was to review the before‐after effect of PS laser in Asians for the treatment of pigmentary disorders. Methods PubMed, Embase, and Cochrane library were searched for papers published up to May 2020. The evaluations were summarized into a 4‐point scale that ranged from <25% (poor), 25‐50% (fair), 50‐75% (good), and 75‐100% (excellent). Effect sizes (ESs) were calculated according to laser wavelengths and lesion types. Results There were two randomized controlled trials, three single‐arm trials, and three case series, with 200 patients. At 3 months after treatment, of all included patients, 3% (95%CI: 1%‐6%) were evaluated as poor or worse, 9% (95%CI: 2%‐21%) as fair, 29% (95%CI: 12%‐50%) as good, and 56% (95%CI: 28%‐83%) as excellent. The 532 & 1064 and 755 nm PS lasers had similar ESs across all four response groups. Conclusion This meta‐analysis suggested that 56% of Asian patients who underwent PS laser for the treatment of pigmentary disorders were evaluated as "excellent" about the pigment clearance by a dermatologist at least 3 months after treatment.
