Laser hair removal is based on the principle of selective photo thermodynamics. By reasonably adjusting the pulse width of the laser wavelength energy, the laser can pass through the skin surface and reach the hair follicle at the root of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thereby making It is a technology that causes the hair to lose its ability to regenerate without damaging the surrounding tissue, with minimal pain. Laser hair removal is currently the safest, fastest and most durable hair removal technology.
Due to the abundance of melanin in hair follicles and hair shafts, specific wavelengths of lasers target melanin for precise and selective hair removal treatments. After the melanin absorbs the energy of the laser, the temperature rises sharply, which causes the destruction of the stem cells of the hair follicle tissue and removes the hair.
