Core tip: summer is coming, and more and more women choose laser hair removal. Laser permanent hair removal is a very safe and fast hair removal method. The heat generated by laser goes deep into the skin to the hair follicle, destroys the activity of hair follicle and has the effect of permanent hair removal. However, laser hair removal needs enough treatment to ensure permanent hair removal.
I have met the needs of beauty loving women. Now many plastic and beauty institutions continue to launch various high-tech beauty and body projects, among which laser hair removal is deeply loved by female friends. Generally, after a course of treatment, most of the body hair will fall off permanently. Moreover, laser hair removal is simple and safe with less adverse reactions. When many women choose laser hair removal, they also hope to understand the principle of laser hair removal. Let’s have a look.
Laser hair removal is based on the principle of selective thermodynamics. Simply put, it is to destroy hair follicles by laser and play the role of depilation. Usually, when our hair follicles are in the growth period, melanin is the most and the absorption of laser is the strongest. The more melanin, the higher the hit rate of laser and the more thorough the damage to hair follicles.
Usually, a certain light wavelength is set on the laser hair removal instrument to track the melanin hair follicle. The light beam emitted by the laser penetrates the surface of the skin and goes deep into the hair follicle under the skin to heat the melanin. After absorbing light energy, the melanin is transformed into heat energy, forming an instantaneous local high temperature, which makes the hair follicle wither and lose activity, so as to achieve the purpose of permanent hair removal.
Laser hair removal is suitable for the body hair of any part of our body. Whether it is leg hair, lip hair, armpit hair, bikini hair and other excess hair, it can achieve the effect of permanent hair removal through laser hair removal.
Female friends who want to wear all kinds of short skirts at will in summer should also pay attention to several points when choosing laser hair removal: first, if you want to achieve the effect of permanent hair removal, it is suggested that you must insist on completing the treatment course. Laser permanent hair removal can not be completed twice at a time. It needs to destroy hair follicles continuously, so don’t stop after two or three times. In this way, hair follicles may grow new body hair after a period of time. It usually takes at least 3 to 5 times to achieve permanent hair removal by laser. Second, after laser hair removal, the skin is easy to be sensitive and fragile. It is very important to take good care of the skin. In addition to adding nutrition to the skin, we must do a good job in sunscreen, otherwise it will cause secondary damage to the skin. I hope women who love beauty can depilate by laser and make themselves beautiful.
