The laser generated by the laser bar can penetrate the epidermis to the hair follicle. According to the principle ofselective photothermalthe energy ofthe laser is preferentially absorbed by the melanin in the haireffectively destroying the hair follicle and hair shaft and then the hair loses the ability to regenerate:The effect is confined to the hair follicles so as to prevent the heat energy from damaqing the surrounding tissues. As the wavelength increasesthe absorption rate of melanin decreasesbut the penetration of the laser is deeper(which means that the epidermis is lesslikelytobeheated);755m 808/810nm.and 1064nm can all be used for hair removal treatment.
