A review of melasma treatment focusing on laser and light devices.

Melasma is a pigmentary disorder of unclear etiology with numerous treatment options and high recurrence rates. Laser and light therapies may be utilized cautiously as second- or third-line options for recalcitrant melasma, but low-energy settings are preferred due to the risk of postinflammatory hyperpigmentation and melasma stimulation. Commonly used lasers include the low-fluence 1064-nm Q-switched neodymium-doped yttrium aluminum garnet laser, nonablative fractionated lasers, and intense pulsed light. Strict sun protection, concomitant use of bleaching agents, and maintenance treatments are necessary. A variety of other treatments that may also help to improve results are now being more widely adopted, including oral tranexamic acid, pulsed dye laser, antioxidants, and laser-assisted drug delivery. ©2016 Frontline Medical Communications.
