Hello? Laser hair removal is based on the principle of selective photothermal kinetics. By adjusting the laser wavelength and pulse width reasonably, the laser can pass through the skin surface and reach the hair follicle at the hair root. Light energy is absorbed and converted into heat energy that destroys hair follicle tissue, so that hair loses its regeneration ability without damaging surrounding tissues, and the pain is mild. It's ok to go to a regular unit to do Yisi plastic surgery. The local area is quite good. Many people come here.
