The coarse hair on the leg only increases the aesthetic feeling of the leg, which looks very indecent, especially for women, which seriously affects the aesthetic feeling of the leg. Even wearing stockings in autumn and winter can be seen vaguely. Then laser leg hair removal is a fast, safe and permanent hair removal method. It is based on the principle of selective photothermal dynamics. By reasonably adjusting the wavelength and pulse width of the laser, 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, thus making the hair lose its regeneration ability without damaging the surrounding tissues. The growth cycle of hair follicles is inconsistent, and leg hair has some potential hair growth ability, that is, incubation period, which means that laser is effective for regenerative hair follicles, but not for dormant hair follicles. Therefore, according to the hair growth characteristics of different parts, after several treatments, excess hair can be removed from all parts of the body, thus achieving the goal of permanent hair removal. Finally, Astor experts remind you that you must choose a regular plastic surgery hospital for hair removal. [Editor: Rowling]
