We know that there is light wavelength. The longer the wavelength, the deeper the penetration depth of the material. Different materials for different wavelengths of light absorption efficiency is not the same. Therefore, the scientists have found a suitable wavelength range (600 ~ 1100 nm), so that the laser beam can penetrate into the depth of the hair follicle, and make the most of the melanin absorption of laser energy .
Thus, the laser energy to reach the vicinity of the hair follicle, hair melanin large energy absorption, rapid temperature rise, resulting in destruction of the hair follicle, hair is removed.
In this process, most of the energy absorption of melanin hair follicle, and therefore diffuse into the surrounding tissue to the energy of the skin is relatively low, in the course of treatment, almost no special skin discomfort, skin surface before and after surgery no apparent difference. Thus realize the goal of hair removal.
