The laser targets the pigment located in the hair follicle. The light from the laser is absorbed by the pigment in the hair follicle and this energy is converted to heat which results in thermal damage to the hair follicle. This thermal damage causes permanent destruction of the hair follicles. Simply stated, the darker pigmentation of the hair follicle absorbs more energy than the pigment in the surrounding skin. Therefore the laser raises the temperature of the hair follicle safely without damage to the surrounding skin. Unlike electrolysis, which kills one hair follicle at a time, the laser reaches and treats hundreds of follicles at a time
