Can laser depilation cause side effects

Many people think that too much hair affects the appearance, and it will leak out when wearing short sleeves in summer, making others uncomfortable, so they will choose depilation, and there are many methods of depilation. Some people will choose drug depilation, while others will choose laser depilation. Then some people will ask whether laser depilation has side effects?

Can laser depilation cause side effects? Laser hair removal mainly uses light and heat to remove the hair. The laser passes through the skin to reach the hair follicle and destroys its tissue to make it fall off. In this way, the hair follicle will lose its ability to grow and will not grow again. Laser hair removal is a relatively safe and long-term hair removal technology.

Hair removal characteristics

  1. The best wavelength is used for treatment: the laser can be fully and selectively absorbed by melanin, and the laser can effectively penetrate the skin to reach the position of hair follicle. The effect of laser is effectively reflected in the melanin in the hair follicle to generate heat for hair removal.

The laser can be fully and selectively absorbed by melanin. At the same time, the laser can effectively penetrate the skin and reach the position of hair follicle

  1. For the best hair removal effect, the laser pulse time required is related to the thickness of the hair. The thicker the hair, the longer the laser action time is required, which can obtain the ideal effect without damaging the skin.
  2. Laser hair removal treatment will not produce pigment precipitation on the skin surface after hair removal like the traditional hair removal method. This is because the skin absorbs less laser during laser hair removal treatment.
  3. The use of cooling system can effectively protect the skin from laser burning in the whole process.

Hair effect

  1. Hair can be divided into three periods: growth period, degenerative period and quiescent period. The energy emitted by the laser instrument can only destroy the hair follicles in the growth period and has no obvious effect on the hair in the degenerative and quiescent period. Only after these hair turn into the growth period can the laser work. Therefore, laser hair removal needs many times of treatment and the effect can be obvious.
  2. If the proportion of a certain part of hair in the growth period is small, the number of treatments should be increased. On the contrary, the number of treatment can be reduced.
  3. Based on different parts of hair, there are different growth cycles, and the interval of each treatment is also different. If the head hair has a relatively short rest period, the interval can be as short as 1 month; The hair rest period of trunk and limbs is relatively long, so the treatment interval should be about 2 months, so you can easily enjoy the confidence brought by silky skin.
  4. If the hair follicle density of a certain part is too high, the laser energy should be appropriately reduced during treatment.

Adaptive object

Laser hair removal is applicable to dark and light hair in all parts, but it is not effective for white hair and excess black hair in all parts of the body. Electroacupuncture, medicine, electric tweezers and other instruments are ineffective or unsuccessful in hair removal.

matters needing attention

  1. Go to the plastic surgery hospital and see an experienced doctor. First of all, determine the location and scope of depilation, because depilation is long-term, and depilation according to a certain range can have cosmetic effect.
  2. When the laser passes through the skin, it has a certain sense of warmth, which is a normal phenomenon. For people who are particularly sensitive, doctors will selectively use a little surface anesthetic, and those who seek beauty can complete hair removal in pleasure.
  3. After each depilation for 20 days, go to the plastic surgery hospital for review in time. The doctor will determine the depilation effect and arrange the next depilation time and range according to the specific situation.

The skin of human body is a relatively transparent structure. The clinical experiment of plastic and cosmetic experts found that in front of powerful laser, the skin is simply a piece of transparent cellophane, so the laser can pass through the skin very smoothly and reach the hair follicle. Because there is a lot of melanin in the hair follicle, it can preferentially absorb a large amount of laser energy and finally convert it into heat energy, so as to increase the temperature of hair follicle and destroy the function of hair follicle.
