A Split-Face, Single-Blinded, Randomized Controlled Comparison of Alexandrite 755 nm Picosecond Laser vs. Alexandrite 755 nm Nanosecond Laser in the Treatment of Acquired Bilateral Nevus of Ota-like Macules (ABNOM)

Q-switched alexandrite lasers (QSAL) have been used for the treatment of acquired bilateral nevus of Ota-like macules (ABNOM). Currently, picosecond alexandrite laser (PSAL) pulses have become available for pigmentary disorders. However, no studies have compared PSAL and QSAL in the treatment of ABNOM.
