Diode laser hair removal system is accomplished when destroying the hair follicular unit by the thermal damage of laser fluency and thus inhibiting future hair regeneration from the follicle. The widely optional pulse duration (Max 1500ms) of P808 diode laser system can produce thermal damage in hair matrix stem cells and ensure follicular destruction. In order to minimize the discomfort of thermal damage to surrounding skin cells, an efficient skin-cooling system is used to chill the skin before, during and after the hair removal treatment. Therefore,P808 diode laser is more effective for hair removal in patients with all skin types.
