title: Lasers, light, and acne.
abstract: Acne vulgaris is a highly prevalent disease with significant potential for physical and emotional scarring. Acne lesions have long been noted to improve after exposure to sunlight. This improvement may be secondary to activation of endogenous porphyrins produced by Propionibacterium acnes. Recently, several investigators have presented studies in which light of particular wavelengths has been used to treat acne vulgaris. In this article, we review the results of these studies as we look to the future of light-based acne treatment.
