How does laser hair removal work?

    Laser hair removal is based on the theory of selective photothermal action. Hair follicles and hair shafts are rich in melanin, and lasers can precisely and selectively target melanin for hair removal. After the melanin absorbs the energy of the laser, the temperature rises sharply, which causes the destruction of the surrounding hair follicle tissue and removes the hair.

How many treatments are needed for laser hair removal?

    The growth cycle of hair is divided into anagen phase, catagen phase and telogen phase. Hair in the growth phase has the highest melanin content in the hair follicle, and the effect of laser hair removal is the best. The laser has basically no obvious effect on the hair in the degenerative and resting periods, so the laser works only when these hairs are in the anagen phase. It usually takes 3-6 treatments to achieve permanent hair removal.

Is laser hair removal safe?

    The wavelength used in laser hair removal technology is a selective wavelength. The laser targets the hair shaft and destroys the hair follicle through the instantaneous heating of the hair shaft. The skin absorbs relatively no laser energy or very little laser energy, so there is no damage to the skin itself and the sweat gland function is not affected at all. Therefore, laser hair removal is safe.
