Laser treatment for pigmented lesions: A review

Background: Just a few decades ago, before lasers were introduced into dermatologic practice, many cutaneous lesions were untreatable. Since the introduction of lasers in dermatology in the 1960s and its revolution by Anderson and Parrish in the 1980s based on the selective photothermolysis theory, lasers have become a main component of many dermatology practices. With the advent of these selective lasers and their constant technological advancements, many lesions can now be easily removed with a low incidence of complications, creating a high demand for laser surgery. Aims: This paper will review current laser systems used for pigmented lesions. Methods: An English-language literature search and review through Medline from January 1994 to October 2004. Review of the latest techniques and lasers used in treating pigmentary disorders and possible future applications and treatment options. Conclusions: Laser technique and technology has greatly advanced producing more effacious treatment with minimal complications.
