Laser treatment of pigmented lesions.

Several pigment-specific lasers can effectively treat epidermal and dermal pigmented lesions without complications using the basic principles of selective photothermolysis. Although such pigmented lesions as solar lentigines and nevi of Ota are relatively easy to treat using pigment-specific laser technology, café-au-lait macules and melasma show variable responses to treatment. New, long-pulsed pigment-specific lasers may prove to further enhance the clinical results obtained in resistant pigmented lesions and other conditions.
