Laser hair removal has become one of the most common cosmetic procedures performed in the United States, ranked second among cosmetic procedures behind Botox injections in frequency of procedures performed. Laser hair removal utilizes beams of highly concentrated light designed to selectively penetrate into the hair follicles, to be absorbed by the pigment in the hair follicles and to destroy the hair within that hair follicle. This fact sheet provides information about laser hair removal, including description of the procedure; what it can help/cure; what to expect before, during and after the procedure; and complications that can occur.
