The principle of laser hair removal

Abnormal hair growth or hirsutism is partly sporadic and can also be related to the use of certain medications (such as androgens) and hirsutism, which can greatly affect appearance. The hair removal areas are mainly concentrated in the armpits, upper and lower limbs, and upper lip of women, and the cheeks, neck and chest of men.

Laser hair removal is based on the principle of selective photothermal action of hair follicle tissue. Laser light tuned to a specific wavelength travels through the epidermis to the dermis. Melanin in hair follicles and hair shafts selectively absorbs light energy. When the nipple is destroyed, the hair no longer grows. Because the process of heat absorption and necrosis of hair follicles is irreversible and will not damage normal skin tissue, laser hair removal can achieve the therapeutic effect of permanent hair removal.

The hair growth cycle is divided into anagen, telogen and catagen. The hair growth cycle of different parts is not the same. Generally, satisfactory hair removal results can be obtained after 5 laser treatments.

The interval between laser hair removal treatments is generally 4-6 weeks. During this period, patients cannot shave or pull out new hairs by themselves, so as not to stimulate the activity of hair follicles. Choose winter hair removal. If new hair grows on the treatment area, it can be covered with clothes, which has good concealment.

If you choose summer hair removal, you need to strictly protect yourself from the sun within one week after hair removal, avoid high-intensity ultraviolet radiation and hot water washing, while winter hair removal does not require special post-operative care. At the same time, hair removal in winter can avoid adverse reactions such as folliculitis caused by sweating and greasy skin. Therefore, laser hair removal in winter is more convenient and timely than in summer.

In addition, remind women to avoid menstruation and pregnancy for hair removal. After treatment, hair removal creams and razors cannot be used to treat hairy parts. At the same time, avoid bathing with hot water that is too hot, and use suitable moisturizers to prevent dry skin.
