The Beneficial Effect on Pigmentation Using Laser Epilation as an Initial Treatment Approach for Becker's Nevus in Asian Skin

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.
