Analysis of three misunderstandings in laser hair removal

Recently, many netizens asked yuemei.com editors about laser hair removal. Through their questions, yuemei.com editors found that most of them fell into three major misunderstandings. Here they sorted it out for your reference. The details are as follows:

Myth 1: is laser hair removal safe

Laser hair removal is a very safe hair removal formula, which is highly professional, has no side effects on the human body, has little impact on the skin, and even has the effects of whitening and moisturizing. Of course, the achievement of these effects requires mm to choose a dermatologist with rich clinical experience to avoid improper operation, resulting in skin scald caused by laser irradiation for too long.

Myth 2: take it off once, is it effective?

It is reported that laser hair removal generally takes three to six times to remove the hair. There are two reasons: first, most hair follicles are tied together in groups of three and open in the same pores. A hair in the pores 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, and the degenerative period is 25%, and the resting period is almost invalid. Therefore, it is necessary to select an appropriate growth stage for hair removal.

Myth 3: does hair removal affect perspiration?

It will not affect perspiration, because perspiration mainly depends on small sweat glands, and the opening of small sweat glands is not in hair follicles. At the same time, laser hair removal is to sweep hair follicles and will not damage sweat glands. Therefore, it will not affect human metabolism and perspiration.

According to the editor of yuemei.com, the principle of laser hair removal is the principle of selective Thermodynamics: that is, the selected wavelength only acts on melanin, not on normal skin tissue; The selected pulse width also only acts on the melanin in the hair follicle, not on the melanin in the basal layer of the skin. At the same time, when doing laser hair removal surgery, mm must choose experienced doctors. Only in this way can they ensure the hair removal effect and safety.
