Diode Laser

Diode lasers use the principle of selective photothermolysis (abbreviated SPTL) to target specific chromophores in the skin, usually melanin or blood. The lasers damage the chromophores by selectively heating them while leaving surrounding tissue unharmed. When treating unwanted hair, for example, the melanin in the hair follicles is targeted and damaged which results in the disruption of hair growth and regeneration. A diode laser can be complemented by cooling technology or other pain-reducing methods which improve treatment efficacy and patient comfort. Laser energy is selectively absorbed by the melanin in the hair follicle and converted to heat, diffusing to and injuring stem cells in bulb and bulge. Most hair is permanently removed. Hair that does regrow is finer and lighter than before.
