Efficacy of 1064nm Q-switched laser with small light spot in treatment of melasma

Abstract

Objective To evaluate the efficacy and experience of Q-switched laser with small light spot in the treatment of melasma. Methods Forty-six patients with melasma were emolled in study. Subjects received total of forty-six patients treatment with 1064 nm Q switched laser at one month intervals. Light spot of 3-4 nm were used. Results Forty-six patients completed the trial. The physician evaluation showed that 50% of patients achieved 90% to 100% clearance, and 89.1% patients achieved 60% to 90% clearance. Side effects was minimal and all the patients tolerated the treatment well. Conclusions Small light-spot and low-energy 1064 nm Q Switched laser is substantially effective and highly safe for the treatment of melasma.
