How does laser hair removal work?
Laser hair removal is actually based on the use of extended selective photothermolysis. Because in order to achieve permanent hair removal, the hair follicle stem cells must be destroyed, and the hair follicle stem cells are located in the bulb of the hair follicle, which is relatively deep, deeper than the hair shaft of our epidermal hair, and there is no melanin there. And our hair removal laser is mainly based on melanin, so the hair removal laser actually acts on the melanin in the hair shaft to generate enough stem cells to diffuse from the hair shaft on the skin surface to the hair papilla, thereby destroying the hair follicle stem cells to achieve The purpose of permanent hair removal.
Laser hair removal is currently the most effective and safe hair removal method. It uses the principle of selective photothermal action. During hair removal, the laser can act on the target tissue with high selectivity, penetrating the epidermis directly to the dermis, and using melanin as the target to destroy hair follicle stem cells. , perform precise and selective hair removal treatment to achieve short-term or permanent hair removal effects. The treatment process will not cause damage to the sweat glands and sebaceous glands around the hair follicles, nor will it affect sweating and oil secretion. The treatment effect depends on hair color, skin color, adjustment of laser equipment parameters, etc. Generally speaking, the lighter the skin color and the darker the hair color, the better the effect.
Laser hair removal requires a course of treatment to achieve permanent hair removal. This is because hair growth has a cycle, including the growth phase (about 3 years), the regression phase (about 3 weeks), and the resting phase (about 3 months). Laser hair removal mainly targets hair in the growth phase. Laser treatment is not effective on hair in the catagen and resting phases. Therefore, laser treatment is only effective when the hair in the treatment area enters the growth phase. Since the hair growth cycle is slightly different in different parts of the body, the interval between hair removal treatments is generally 4 to 8 weeks, and the treatment course is 4 times. People with excessive hair can achieve good cosmetic results after hair removal treatment. For people with hirsutism, laser hair removal treatment can still have good results on the basis of removing the cause and treating the primary disease.
Will perspiration be affected after laser hair removal?
The laser will only work on the melanin in the hair follicles. Hair follicles and sweat glands are not the same tissue. There is no melanin in the sweat glands, so it will not affect perspiration. The laser can make the hair in the hair follicle fall off automatically, without the hair, not only the skin is smoother, it is easier to keep dry and it also helps to reduce body odor.
1. After laser hair removal, the pores are easy to open. It is recommended to avoid bathing and swimming within the first day after hair removal to prevent inflammation.

3. Pay attention to sun protection after laser hair removal, because laser treatment achieves the purpose of permanent hair removal by destroying hair follicles at high temperature. After laser treatment, the skin on the part irradiated by laser will be relatively fragile, and it is easy to cause pigmentation after sun exposure, although It will disappear in the future, but it will take some time.
4. Eat more fruits containing vitamin C after laser hair removal, or take vitamin C tablets directly. Vitamin C can improve skin resistance, reduce pigmentation, do not eat irritating food.
