Is laser hair removal reliable?

Too much hair can sometimes affect a person's appearance. Most of the body hair on the body is not very useful, so we can remove it. At present, the mainstream hair removal method on the market is laser hair removal. Some people don't know much about laser hair removal, so they often worry about the safety and comfort of laser hair removal. Here are the principles and effects and safety of laser hair removal.

1. The principle of laser hair removal

Generally, laser hair removal is based on the principle of selective thermodynamics and uses the latest laser technology. The laser beam will pass through the surface of the skin, reach the hair follicles, and finally be absorbed by the hair follicles. By absorbing the light energy of the laser, the hair follicles will be converted into heat energy, which will damage the hair follicles and the hair cannot grow. At the same time, melanin can easily absorb the energy of a laser and will not cause damage to the surrounding skin.

2. The effect of laser hair removal

Determine how many times the hair needs to be treated according to the specific situation of the individual. Hair growth is generally divided into a growth period, retreat and rest period, and cycle back and forth in three cycles. However, laser hair removal is only effective for the hair during the growth period, and has no effect on the retreating period and the hair period. Generally, about one-third or five of the hair. Therefore, laser hair removal generally requires about five continuous treatments to achieve permanent hair removal.

3. Safety of laser hair removal

In the 1960s, it was found that ruby laser can destroy hair follicles, but it was not applied to the clinic. In the 1980s, ruby laser treatment was treated with pigment mole, and hair loss was also found, but at the time, it caused serious damage to the epidermis. In the 1990s, ruby laser and NDYAG laser were successively applied in the field of hair removal, but the parameter design was still not ideal. The subsequent semiconductor laser hair removal instrument began to be applied in the field of hair removal. The technology has basically matured and the hair removal effect is significant. The technical security index is very high and the risk factor is very low. There is basically no pain when hair removal. The laser penetrates the epidermis and is directly absorbed by the hair follicles without damaging the epidermis or leaving scars. No special care after hair removal can maintain normal daily activities. Therefore, diode laser hair removal is currently very safe and very convenient for hair removal operations.
