Comparative Effectiveness of 755‐nm Picosecond Laser, 755‐ and 532‐nm Nanosecond Lasers for Treatment of Café‐au‐Lait Macules (CALMs): A Randomized, Split‐Lesion Clinical Trial

PS-755 nm, QS-755 nm, and QS-532 nm laser treatments were equally effective in treating and improving CALMs. PS-755 nm caused fewer adverse effects. Individuals can react differently to different types of lasers. Patch tests should be conducted before the treatment. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.
