Nanchang Jiamei’s laser hair removal method is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength energy pulse width, the laser can penetrate the skin surface and reach the root follicle of the hair. The light energy It is absorbed and converted into heat energy that destroys hair follicle tissue, thereby causing the hair to lose its ability to regenerate without damaging surrounding tissue and causing minimal pain.
