The hot summer days have arrived, many people began to worry about the heavy body hair: this wear a little less to reveal not only unattractive, but also embarrassing ah. To deal with thick body hair, I believe that we have a lot of weapons in hand: razor, the effect can only last 3 to 5 days, but the hair but the more coarse scraping, but also easy to damage the skin barrier, resulting in skin sensitivity, redness and even inflammation; hair removal cream, the chemical composition of the skin has a greater stimulation, allergies are also very common, the effect can only last 3 to 5 days; wax hair removal, the process is painful, and easy to cause folliculitis, the effect can last 2 weeks. These methods are all temporary hair removal because they do not permanently destroy the hair follicle. So is there a real method that can completely destroy the hair follicle and achieve permanent hair removal? The clear answer is yes, it is laser hair removal. Why laser can remove hair? Everyone has used an electric kettle, right? We fill it with water, turn on the electricity, and the resistance wire in the kettle will constantly heat up and boil the water. Laser hair removal process is similar to this process, the laser can be absorbed by the black material, hair removal is absorbed by our black hair, after absorption will emit heat, this heat spreads around, the whole hair follicles are “burned”, completely destroyed. Hair removal is generally very effective and permanent. Will the laser destroy the rest of the skin structure? With laser hair removal, there is no need to worry about damaging other skin structures besides the hair follicle, because the current laser technology uses the extended selective photothermal action principle, which can precisely control the range of heat diffusion, just to completely “burn off” the hair follicle, while the surrounding skin is completely undamaged, with a high degree of safety. Can I get rid of all the hair at once? Unfortunately, no. Because our hair has a growth cycle, divided into anagen, regression and resting phases. Only after the laser is absorbed by the hair in the anagen phase can the hair follicle be completely destroyed, while the hair in the anagen phase only accounts for 85%, the rest is in the “hibernation” state, that is, the regression phase and resting phase. After a hair removal, after a few weeks to a few months, most of the remaining hairs will also enter the anagen phase, and then they can be removed by another treatment. Therefore, laser hair removal usually requires 3 to 5 treatments to get rid of them more cleanly. Does hair removal affect sweating? Hair follicles and sweat glands are independent of each other, so laser hair removal will not affect sweating at all. Finally, I would like to remind all readers who want to remove hair that although laser hair removal is safe and effective, there may be side effects, which are related to the laser hair removal equipment and the operation of the physician. It is recommended to go to a regular hospital to choose the right hair removal laser in order to finally get a smooth and beautiful skin.
