At present, the latest laser hair removal technology is to use semiconductor freezing point painless hair removal laser instrument, which is also commonly known as freezing point hair removal. Semiconductor freezing point hair removal relies on the principle of selective photothermal action, which makes hair follicles produce high heat, thus destroying hair follicle structure and achieving the purpose of hair removal. Disadvantages: The darker the skin color, the greater the risk, and it is easy to cause overheating, scarring or uneven skin color.
Laser hair removal is a safe and fast hair removal technology, 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 root of the hair, and the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue.
Laser hair removal is less painful and can be applied to deep hair follicles in different parts, which can completely remove hair. Laser can selectively act on skin tissues without damaging normal epidermis and tissues. The treatment time is short and does not affect normal work and life. The depilation site may produce slight redness, skin sensitivity and a feeling of heat or itching, and ice can be used to relieve the pain.
