The temperature gradually rises, and it’s the “exposed” season again. For some “hairy kids”, they would rather wear long sleeves than shorts and short sleeves, just because they are afraid of showing their hair. In order to solve this embarrassment, medical cosmetology launched a laser hair removal project. However, we must first understand its principles while pursuing beauty. So, how much do you know about laser hair removal? Is it safe or not?
The principle of laser hair removal
The principle of laser hair removal is to destroy hair follicles by generating heat by laser, so as to achieve the effect of hair loss. The specific operation process is to first take off the hair that needs the laser with a spatula, so that the laser can better aim at the root of the hair, so as to walk down the hair to the position of the hair follicle. The heat generated by the laser starts to work at this time to destroy the hair follicles. Repeat this step several times to achieve the final hair removal effect.
Since laser irradiation emits heat, it will be accompanied by some burning sensation during use. This kind of pain is more like the sensation of small needles or rubber bands on the skin, so some girls who are afraid of pain do not need to worry too much.
Laser hair removal is not like surgery that can be done at one time. It is a gradual process. Hair follows a unique growth cycle, including dormancy, shedding, and growth periods. For most people, laser hair removal requires multiple treatments within two to three months to achieve results.
If the necrosis of the hair follicles does not grow any longer, hair removal is permanent. But there are also hair follicles that are just damaged and not necrotic. In this case, the hair will grow out again, so a second treatment is needed.
Possible side effects of laser hair removal
Laser hair removal technology has been approved by the FDA (U.S. Food and Drug Administration) in 1997. It has 22 years of clinical history and is widely used by the general public.
Laser hair removal is basically stable on the technical level, so there is no personal safety risk, but slight side effects may still occur, such as:
1. After laser treatment, the skin may be reddened;
2. Blisters may appear on the skin;
3. There may be pigmentation in the area irradiated by the laser.
Laser hair removal works well for most people. This method of hair removal is relatively less harmful and can last a long time. But we remind everyone here that when choosing laser hair removal, you must go to the formal Hospital institutions are carried out by professional personnel to avoid some adverse consequences due to improper use of equipment.
