Laser hair removal works by emitting pulses of laser energy to the hair follicles. This energy is absorbed by the pigment in the follicles, and they become disabled. Up to now, treating darker skin types has been a problem because darker skin absorbs enough of the laser energy to cause adverse side effects. To overcome this obstacle, the Candela GentleYAG laser is used. This technology delivers each pulse of laser energy to the skin over a longer period of time than other hair removal lasers. This longer delivery time (pulse width) minimizes the amount of heat that builds up in the skin but still allows enough heat to reach and disable the hair follicles. The Candela GentleYAG is effective on all skin colors (types 1-6). Multiple treatments are generally required and depends on the color of your hair and skin, as well as factors such as hormone levels and hair follicle size. The laser is effective on all skin tones and ethnicities; however, gray, white/silver, blonde and some shades of red hair cannot be treated. The treated area may become slightly red and puffy; however, the reaction typically subsides within a day and you can return to normal activity immediately.
