Picosecond lasers have shown promise in treating pigmentation disorders and may represent an improvement in both treatment efficacy and patient comfort over commonly used quality-switched lasers.1-3 Picosecond lasers have a selective photomechanical effect, causing mechanical breakdown of pigment into smaller fragments that are more easily cleared; the lasers also produce minimal thermal irritation to the surrounding tissue.2
