Efficacy and safety of a novel picosecond laser using combination of 1 064 and 595 nm on patients with melasma: A prospective, randomized, multicenter, split-face, 2% hydroquinone cream-controlled clinical trial.

A 750 picosecond laser using 1 064 and 595 nm was effective and safe for the treatment of Korean melasma patients. The picosecond laser with dual-wavelength used in this study can reduce the photothermal effect generated during the removal of pigment and total duration of the procedure, and can be expected to reduce the occurrence of adverse events.
