Laser hair removal time

The time of laser hair removal depends on the treatment area. Laser hair removal is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength, the light beam will penetrate the surface of the skin and finally be absorbed by the hair follicle. Through the selective absorption of laser energy, the hair follicle will be damaged, so that the hair will lose the ability of regeneration without damaging the surrounding tissues

Hair is divided into three periods: growth period, degenerative period and quiescent period. The energy emitted by the laser instrument can only destroy the hair follicles in the growth period, and has no obvious effect on the hair in the degenerative and quiescent period. Only after these hairs turn into the growth period can the laser work. Therefore, laser hair removal requires multiple treatments, and the effect can be obvious If the proportion of a certain part of hair in the growth period is small, the number of treatments should be increased On the contrary, the number of treatment can be reduced

The time of laser hair removal needs to be determined according to its own hair growth, and the time of each hair removal depends on the area of the part. It is painless, fast, complete, safe and effective
