Secondly, when it comes to security, it is the safest, fastest and most lasting technology at present.

Misunderstanding of laser hair removal
1. Is laser hair removal safe?
Laser hair removal is a very safe hair removal method: it has strong pertinence, no side effects on human body and almost no influence on skin.
2. Precautions for laser hair removal
When doing laser hair removal, it should be noted that the hair removal part should be protected from the sun one week before treatment and two weeks after treatment, and it is not advisable to do hair removal, beeswax hair removal and electrolytic hair removal two weeks before treatment.
3, the number of laser hair removal needs
Laser hair removal usually takes three to six times, mainly due to two factors: first, most hair follicles are tied together in groups of three and open in the same pore, and one hair in the pore is the hair of one of the three hair follicles below it, so one treatment can only destroy one hair follicle in a group; Second, hair growth goes through growth period, regression period and rest period. Laser hair removal is effective in the growth period of 75%, in the regression period of 25%, and almost ineffective in the rest period.
4. Laser hair removal will not affect perspiration.
The laser removed by laser only acts on melanin in hair follicles, but there is no melanin in sweat glands, so it will not absorb laser to damage sweat glands and has no other adverse effects on human body. Therefore, laser hair removal will not affect perspiration.
5. Is laser hair removal harmful to the skin?
The human skin is a relatively light-transmitting structure. Clinical experiments by plastic surgeons have found that the skin is simply a transparent cellophane in front of a powerful laser, so the laser can penetrate the skin smoothly and reach the hair follicle. Because there is more melanin in hair follicle, it can preferentially absorb a large amount of laser energy and finally convert it into heat energy, thus increasing the temperature of hair follicle and destroying the function of hair follicle. In this process, because the skin relatively does not absorb laser energy, or absorbs a small amount of laser energy, the skin itself will not be damaged.
