Laser hair removal is a cosmetic procedure that uses a concentrated beam of light (laser) to remove unwanted hair. During the procedure, the laser emits a light that is absorbed by the pigment (melanin) in the hair follicle, which damages the follicle and prevents future hair growth. (laser)  hair removal can be used to remove hair from various parts of the body, including the face, arms, legs, bikini area, and back.
