The dangers of laser armpit hair removal

Sweat hair is an integral part of the human body. The reason why sweat hair grows on the human body is that it can promote sweating. This phenomenon often happens in people's lives, so there needs to be a substance that can expel sweat from the body. Sweat hair can help to expel sweat and prevent people from developing other disease symptoms, but excessive, dense and heavy sweat hair will affect their image. So what are the dangers of laser armpit hair removal?

1. Damage to hair follicles

Although laser hair removal does not cause damage to the skin surface, the heat light acts on the deep layer of the skin, damaging the hair follicles and causing them to shrink. There may be slight redness or local edema in the treated area, which usually disappears within 12-24 hours. The skin keratin is very thin after surgery.

2. Laser hair removal has the risk of pigment changes

Laser hair removal is a non-ablative dynamic therapy that utilizes the selective principle of laser. Different wavelengths can be absorbed by different skin pigments, which can easily lead to darker or lighter pigments. For example, laser hair removal can easily burn the epidermis due to excessive energy, or be ineffective due to insufficient energy.

3. Affects sweating function

The human body sweats through the sweat hair on the body, so taking it off will definitely affect this function. Therefore, laser hair removal can easily affect the normal sweating function of skin pores.

4. May leave scars

Laser hair removal has certain requirements on the quality of the treatment equipment. Poor quality equipment can easily cause skin burns or leave scars.

The hazards of laser hair removal are related to the laser used in laser hair removal. Since hair removal laser only destroys hair follicle cells in the growth phase, it does not completely destroy the hair follicles in the resting phase and the degeneration phase, so some hair follicles will regenerate. Therefore, laser hair removal requires three or four treatments to achieve permanent hair removal, and each treatment must be separated by one to two months.

The so-called permanent hair removal refers to the situation where the hair cannot grow again after one growth cycle. The growth cycle of hair follicles varies depending on the location of the hair. For example, the growth cycle of beard is about four months, while the hair on the back grows to one year. The postoperative observation time can be determined according to the hair in different parts of the body. If the hair does not grow after this observation period, it can be called permanent hair removal.

An ideal hair removal method, laser hair removal has the advantages of being fast, permanent, having no side effects, and being able to remove a large area of ​​hair at one time. There is no need to worry about the dangers of laser hair removal. Laser hair removal can achieve permanent hair removal in a relatively painless way, but it also requires several treatments. Therefore, when choosing a hair removal method, you may need to consider the location and size of the hair removal area. The only method that can achieve permanent hair removal in one go is electroacupuncture, but this method can only remove a small amount of hair at a time and has the side effect of burning and injuring the skin.
