Abstract：
Becker\'s nevus (BN) clinically presents as brown patches with hypertrichosis. The risk of pigmentary changes still remains a concern when using lasers to treat Asian patients with BN. We aimed to evaluate the outcomes on reduction of hairs and pigment of BN using the long-pulsed 1064-nm Nd:YAG (LPNY) and/or 755-nm alexandrite (LP-Alex), before treating pigment in earnest. A total of 13 subjects were treated with the LPNY (n = 8), the LP-Alex (n = 4), and both (n = 1). Improvements on hair removal and pigment reduction were assessed using a 5-point global assessment scale. Patient satisfaction was also assessed. Treatment parameters were within those commonly used for the purpose of epilation. The average follow-up period was 19.5 ± 12.3 weeks, and the mean total number of sessions was 2.0. Eleven subjects reported >50% improvement in hair removal (11/13, 86.7%), and pigment reduction of >50% improvement was observed in 9 subjects (9/13, 69.2%). Patient satisfaction showed >50% lesion clearance in 84.6%. Hair removal settings of LPNY and LP-Alex were effective in both hypertrichosis and pigment reduction in the initial strategy of treatment of BN in skin of color.
