[Photodepilation].

Unwanted hair is a common problem for which different types of light therapy have been developed as the treatment of choice. Since 1996, when the American Food and Drug Administration approved the first laser therapy for depilation, much progress has been made in light-based technology and lasers. Lasers and intense pulsed light sources with red or near infrared wavelengths (600 to 1200 nm) are the most widely used for removing hair as they target the melanin of the hair shaft, hair follicle epithelium, and hair matrix. The aim of this review is to describe and compare the different photodepilation methods currently available.
