The system uses the optimal hair removal wavelength of 808nm 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.

The diode laser hair removal machine is particularly effective to hair follicle melanocytes without injury surrounding tissue. The laser light can be absorbed by hair shaft and hair follicles in the melanin, and converted into heat, thus increasing the hair follicle temperature. When the temperature raises high enough to irreversibly damage the hair follicle structure, it disappears after a period of natural physiological processes of hair follicles and thus achieves the purpose of permanent hair removal.
