DESIGN: This was a prospective study. SETTING: The setting was a singapore-based clinic. PARTICIPANTS: participants included nve women, aged 25 to 38 years, three with skin Type iii and two with skin Type iV. all of them had freckles. MEASUREMENTS: photographs were taken pretreatment and one month after laser treatment. Three independent physicians evaluated the photographs using a grading system. patients were followed clinically for a total of six months post-laser treatment to monitor for post-inflammatory hyperpigmentation and recurrence. RESULTS: at one month post-laser treatment, all nve patients were evaluated. The three independent physicians agreed that all nve patients had greater than 90- percent clearance of their freckles. during the subsequent follow-up visits (up to 6 months post-laser treatment), no post-inflammatory hyperpigmentation, hypopigmentation, or recurrence was seen. CONCLUSION: The erb:Yag laser might be considered an effective and safe treatment for freckles in asian patients.

AUTHOR CORRESPONDENCE: dr. brian Tian, Freckles pephelides) are small brown macules that appear on sun-exposed areas. previously, treatments for freckles included dermabrasion, electrodessication, and chemical peeling. 1 These treatments can cause scarring, among other undesirable side effects. in the past decade, freckles have been repor ted to significantly lighten and clear with Q-switched (Qs) alexandrite (Qsal) and Qs nd:YaG lasers. 2,3 in 2000, Jang et al 2 repor ted the use of a Qsal for freckles in 197 korean patients, all of whom experienced at least 76-percent clearance after an average of 1.5 treatments. rashid et al 3 also showed that a 532nm Qs nd:YaG laser could achieve 50-percent improvement in 14 patients with freckles. while these are good results, there is still a need for a laser technique that can achieve close to 100-percent clearance in as shor t a time as possible, with minimal treatment sessions and minimal to zero complications. in this brief repor t, we present a study of five chinese patients (skin Types iii/iV) whose freckles cleared greater than 90 percent following one treatment session using a fractional 2940nm nonablative erb:YaG micropeel laser. METHODS AND MATERIALS Five chinese patients with freckles were recruited over the course of two months. all five patients were women, with ages ranging 25 to 38 years— three with skin Type iii and two with skin Type iV. These patients were other wise in good health. Those with melasma and those who had major sun exposures or other major skin conditions were excluded from the study. patients who used any topical bleaching creams (hydroquinone) and those who received laser treatment within the past one year were all excluded. This small study was in accordance with the helsinki declaration, as revised in 2013. all patients consented to participate in the study. The patient depicted in the ngures contained herein consented to the publication of her photos. The fractional nonablative 2940nm erb:YaG laser (sp spectro, Fotona, ljubljana, slovenia) was
