Times required for laser hair removal

Laser hair removal generally takes three to six times, mainly due to two factors: first, most hair follicles are bound together in groups of three and open in the same pore. A hair in the pore is the hair growing from one of the three hair follicles in a group below it, so one treatment can only destroy one hair follicle in a group; Second, hair growth should go through the growth period, degenerative period and resting period. Laser hair removal in the growth period is 75% effective, the degenerative period is 25%, and the resting period is almost invalid.

Laser hair removal will not affect perspiration

The laser of laser stripping only affects the melanin in the hair follicle, while there is no melanin in the sweat gland, so it will not absorb the laser ability and damage the sweat gland, and has no other adverse effects on the human body.

Is laser hair removal harmful to the skin

The skin of human body is a relatively transparent structure. The clinical experiment of plastic and cosmetic experts found that in front of powerful laser, the skin is just a piece of transparent cellophane, so the laser can pass through the skin very smoothly and reach the hair follicle. Because there is a lot of melanin in the hair follicle, it can preferentially absorb a large amount of laser energy and finally convert it into heat energy to raise the temperature of the hair follicle, Achieve the purpose of destroying hair follicle function. In this process, because the skin does not absorb laser energy or absorbs a small amount of laser energy, the skin itself will not be damaged.

Is laser hair removal permanent

For the effect of laser hair removal, it can permanently remove hair. Of course, the treatment effect is the best in the growth period of hair. The more melanin secretion, the better the treatment effect. Laser depilation has little effect on hair in degenerative and resting stages.
