Laser therapy for cutaneous hyperpigmentation and pigmented lesions

Abstract

: Selective treatment of pigmented lesions can be accomplished as a result of the recent technologic advancements made in cutaneous laser surgery. Melanin-specific, high-energy, pulsed lasers are being used successfully to remove most benign epidermal and dermal pigmented lesions, including lentigines, cafe-au-lait macules, melanocytic and blue nevi, drug-induced and infraorbital hyperpigmentation, Becker's nevus, and nevus spilus. These acquired and congenital cutaneous pigmented lesions can be lightened and even permanently eradicated after a series of outpatient laser treatments, with minimal risk of permanent sequelae, such as scarring, skin atrophy, or pigmentary irregularities. Because of the enhanced cosmetic effect of these lasers and their relative ease of use, they are becoming the mainstay of treatment for a variety of pigmented lesions and pigmentary disorders.
