Treatment of Melasma With Q-Switched Laser in Combination With Tranexamic Acid

Melasma, a pigmentary disorder that particularly affects Asian women, has been clinically proven to respond effectively to combination therapy of Q-switched lasers and tranexamic acid (TXA), especially with the advancements in laser aesthetics in recent years. However, treatment outcomes can be influenced by factors such as the wavelength and spot size of the Q-switched laser, the route of administration for TXA (including injectable, oral, or topical), as well as the dosage and duration of treatment. This article presents 13 different combination approaches from six randomized controlled trials, indicating that oral administration of TXA in combination with a 1064 nm Q-switched laser is currently the most widely used and effective treatment approach.
