Abstract

The use of lasers in the treatment of a number of different skin disorders and diseases has become commonplace. This tremendous acceptance by both physicians and patients is a direct reflection of the high degree of precision and selectivity provided by lasers, which helps to minimize the risk of side effects and complications while simultaneously maximizing the opportunity for obtaining a satisfactory outcome. In an attempt to remove unwanted or excess hair, the principles of selective photothermolysis have been employed with several different laser and light devices that permit the effective treatment of large areas of hair-bearing skin with minimal discomfort and with low risk of scarring or other complications. It is possible using current laser technology to permanently remove some hair and induce a prolonged delay in the regrowth of many hairs. With additional experience and an improved understanding of how light can influence the rate and quality of hair growth, it is anticipated that permanent hair removal will be achieved in the near future.
