The weather is getting warmer, and many girls are starting to think about their excess hair, which is often annoying. Laser hair removal is a new type of hair removal method, and laser hair removal is very clean and has no side effects, so is laser hair removal dangerous?

【Is laser hair removal dangerous?】

      The human skin is a relatively light-transmitting structure. Clinical experiments of plastic and cosmetic experts have found that in front of a powerful laser, the skin is simply a piece of transparent cellophane. Therefore, as long as the laser of the appropriate wavelength is selected and the time of hair removal is strictly controlled, the effect is still very good. Not bad.

      Laser hair removal is based on the principle of selective photo thermodynamics. By reasonably adjusting the wavelength, energy, and pulse width of the laser, the laser can pass through the skin surface to reach the hair follicle at the root of the hair, and the melanin in the hair follicle and hair shaft selectively absorbs light energy. , The resulting thermal effect destroys the hair follicle without damaging the surrounding tissue, and the pain is mild. For thicker and darker hair, there will be major damage after laser treatment, resulting in degeneration and necrosis of some hair follicle cells, thereby effectively preventing hair regeneration for a long time. For finer and lighter hair, after laser treatment, only At the same time, the partial destruction of the hair follicle causes the deformation and shrinkage of the hair follicle and accelerates its transition from the anagen phase to the anagen phase and the telogen phase, resulting in shorter, thinner, lighter hair and significantly slower hair growth.

      The hair growth cycle can be divided into three phases, namely the growth phase, mature phase, and telogen phase. The laser can effectively destroy the hair follicles of the hair in the growing phase, hindering and stopping the growth of the hair. Laser hair removal is permanent hair removal. The specific intense pulsed light can penetrate the epidermis to the root of the hair follicle so that the temperature of the hair root is rapidly increased, and the hair root is heated and solidified without affecting the secretion of sweat glands, thus achieving the purpose of permanent laser hair removal. The process of laser hair removal is simple, fast, and leaves no scars after the treatment.

      It is very important for this treatment method to be treated under the guidance of a professional doctor. You don’t have to worry about whether laser hair removal is dangerous.

      Laser hair removal requires about 3-5 treatments, with an interval of 20-45 days between treatments. In addition, the semiconductor laser can make the melanin in the hair follicle be highly selectively absorbed, thereby destroying the hair follicle, and the hair can be completely removed and will never grow again. This technique is also known as snow skin hair removal.

First, Precautions before laser hair removal 

1. Before laser hair removal, clean and sterilize the area to be removed. Some women use beeswax for hair removal at home. At this time, it is best to use a small amount of talcum powder to absorb the oil on the skin surface to enhance the adhesion of the wax; in addition, because the capillaries and capillary nerves are concentrated in the hair root, it is easy to cause pain when pulling the hair.

2. Before laser hair removal, wrap ice cubes with a towel and apply cold compresses to the hair removal site to reduce pain. It is not advisable to use too much force when removing hair, otherwise, it will irritate the skin and aggravate the pain.

3. After laser hair removal, it should be disinfected with alcohol, and some anti-inflammatory ointment should be applied to the hair removal site to avoid folliculitis. Doctors do not advocate cutting armpit hair with scissors or shaving axillary hair with a razor blade, because doing so is very easy to injure and cause bacterial infection in the armpit area, which not only causes local pain and discomfort but also easily causes symptoms such as swollen lymph nodes.

Second, Precautions after laser hair removal

1. Please avoid sun exposure for 3 months to half a year after treatment, and apply sunscreen lotion as directed by your doctor to the affected area to reduce sunlight exposure.

2. After the treatment, there may be slight redness and swelling, and the skin is sensitive and hot or itchy. If you feel pain, apply an ice compress to relieve the pain.

3. Avoid hot water scalding and scrubbing of the treatment area.
