Due to evident therapeutic effects, few adverse reactions and short downtime, picosecond lasers have been widely applied to clinical practices abroad. At present, picosecond lasers mainly include 532?nm, 755?nm and 1064?nm lasers. However, picosecond lasers have been used in China for just a few years. This review summarizes principles of picosecond lasers for the treatment of skin diseases, and their application in nevus of Ota, acne scar, tattoo and photoaging.
