The temperature gradually rises, which is the season of “exposure”. For some “hairy kids”, they would rather wear long sleeves than short sleeves, just because they are afraid of showing their hair. In order to solve this embarrassment, medical beauty launched a laser hair removal project. However, while pursuing beauty, we must first understand its principles. So, how much do you know about laser hair removal? Does laser hair removal hurt? What is the principle of laser hair removal? is it safe?
The principle of laser hair removal is to destroy the hair follicles by generating heat from the laser to achieve the effect of hair removal. The specific operation process is to first use a scraper to remove the hair that needs laser, let the laser better aim at the hair roots, and then walk along the hair to the position of the hair follicle. At this time, the heat generated by the laser starts to destroy the hair follicles. Repeating this step several times can finally achieve the effect of hair removal.
Since it is a destructive medical project, will it be painful? In fact, there will be pain, but not very strong. Because laser irradiation will generate heat, there will be some burning sensation when using it. This kind of pain is more like a slight tingling sensation, or the sensation of a rubber band bouncing on the skin, so some girls who are afraid of pain don’t need to worry too much.
How long does it take to remove hair after laser hair removal? Unlike surgical procedures, laser hair removal can be done in one go. This is a gradual process. Hair follows a unique growth cycle, including periods of dormancy, shedding, and growth. For most people, laser hair removal requires multiple treatments within two to three months to achieve results.
Is permanent? If the necrosis of the hair follicles no longer grows, hair removal is permanent. However, there are also hair follicles that are only damaged but not necrotic. In this case, the hair will grow again, so a secondary treatment is required.
Laser hair removal technology was approved by the FDA in 1997. It has 22 years of clinical history and is widely used by the general public. This shows that laser hair removal technology is basically stable, so there is no personal safety risk, but there are still minor side effects, such as:
1. The skin may turn red after laser treatment;
2. Blisters or even large bubbles may appear on the skin;
3. The skin color may be the pigmentation of the laser-irradiated area.
These problems should be understood clearly before hair removal, and communicate with the hair removal doctor according to your past skin conditions to minimize the risk of possible side effects.
