Laser treatment of tattoos

All three Q-switched laser systems can remove most tattoos effectively, with minimal scarring or other adverse sequelae. Despite advances in laser technology, all tattoos cannot be eliminated completely, and several wavelengths remain necessary to treat multicolored tattoos optimally. The major advantage of Q-switched laser irradiation to effect tattoo removal is the low risk of scarring associated with treatment. Limitations include the need for multiple treatment sessions, minimal-to-incomplete responses in some cases, and the possibility of pigmentary and textural changes.
