The temperature is gradually rising, and it's the "dew meat" season again. For some "hairy children", they would rather wear long sleeves than short sleeves, just for fear of exposing their hair. In order to solve this embarrassment, medical beauty launched a laser hair removal project. However, while we are pursuing beauty, we should first understand its principle. So, how much do you know about laser hair removal? Does laser depilate ache? What is the principle of laser hair removal? Is it safe?

The principle of laser hair removal is to destroy the hair follicle through the heat generated by laser, so as to achieve the effect of hair shedding. The specific operation process is to first take off the hair that needs laser with a scraper, so that the laser can better aim at the hair root, so as to follow the hair down to the position of the hair follicle. The heat generated by the laser starts to play a role at this time, destroying the hair follicles, and repeating this step many times can finally achieve the hair removal effect.

Since it is a destructive medical project, will it be very painful? In fact, there will be pain, but it will not be very strong. Due to the heat generated by laser irradiation, it will be accompanied by some burning sensation. This kind of pain is more like the feeling of small acupuncture or rubber band bouncing on the skin, so some girls who are afraid of pain don't need to worry too much.

How long after laser depilation can you remove hair? Unlike surgery, laser hair removal can be completed at one time. It is a step-by-step process. Hair follows a unique growth cycle, including dormancy period, shedding period and growth period. For most people, laser hair removal requires multiple treatments within two to three months.

Is it permanent? If the necrosis of hair follicles does not grow any longer, hair removal is permanent. But there are also some hair follicles that are damaged but not necrotic. In this case, the hair will grow out again, so secondary treatment will be needed.

Laser hair removal technology has been approved by FDA in 1997. It has a clinical history of 22 years and is widely used by the public. This shows that laser hair removal is basically stable on the technical level, so there is no personal safety risk, but there are slight side effects, such as:

1. The skin may be red after laser treatment;

2. Blisters or even bullae may appear on the skin;

3. Pigmentation may appear in the skin color of the parts irradiated by laser.

These problems are what we should know before hair removal, and we should communicate with hair removal doctors according to our skin condition in the past, so as to minimize the risk of possible side effects.
