Abstract: Objective To evaluate the elimination of melasma with nonablative Q-switched Nd : YAG1 064 nm laser. Methods 23 cases of melasma were treated with Q-switched Nd :YAG 1 064 nm laser using the following parameters: spot size, 6 mm; pulse duration, 5-7 ns; frequency, 10 Hz, and flu-ence, 1.8-2. 0 J/cm2. The procedure was repeated weekly. Results The treatment was well tolerated without the use of topical anesthetic. There was slight congestion, no blister and crust after treatment. Routine clean and make-up can be done after treatment. The melasmas were obviously lighten or fully eliminated after 8-10 treatments and 52. 17 % of patients showed excellent results. Only 5 cases experienced an episode of purpura on eyelid after treatment and disappeared spontaneously without post-inflammatory hyperpigmentation and scarring. Followed up over 6 months, there was recurrence in 7 patients who were effective by additional treatment. Conclusions Nonablative Q-switched Nd :YAG 1 064 nm laser is a more ideal method to eliminate melasma because of the credible effect, safe, simple operation, and no downtime, in despite of recurrence.
