During the diode laser hair removal treatment, the laser energy light passes through the skin and is absorbed by the melanin in the hair follicle. 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.
