The system uses the optimal hair removal wavelength of 755 808 1064nm diode for deep penetration into the dermis where the hair follicle is located . In treatment procedure, a series of low fluence, high repetition pulses increases the temperature of both the hair follicle and the surrounding, nourishing tissue to 45 degree Celsius. This more gradual heat delivery uses the chromophores into the surround tissue as reservoirs to effectively heat up the hair follicle. This, along with the heat energy absorbed directly by the hair follicle, damages the follicle and prevents re-growth.
