Laser hair removal is based on the principle of selective photothermal kinetics. By reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the skin surface to reach the hair follicle at the root of the hair, and the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, so that the hair loses its regeneration ability, and may damage the surrounding tissues, resulting in light tingling.
