Detailed explanation of the principle of laser hair removal technology

There are many hair removal methods, which can be roughly divided into two categories: non thermal power hair removal method and thermal power hair removal method. Non thermal dynamic hair removal methods include scraping, pulling, wax hair removal and the use of hair removal cream. These methods can only achieve temporary hair removal effect, and the hair will regenerate soon. Thermodynamic depilation includes electroacupuncture depilation and laser depilation, which belongs to permanent depilation.

Although electroacupuncture depilation can achieve permanent depilation effect, it is more painful when depilating, and it will also produce complications such as scar, which is not easy to be accepted by the public. Laser technology has made great progress in medical cosmetology. The principle of “selective photothermal effect” has been successfully applied to the removal of hair. The specific wavelength laser passes through the epidermis and directly acts on the hair follicle. The melanin of the hair follicle and hair stem selectively absorbs light energy. The resulting thermal effect makes the hair follicle coagulate and necrosis, and the hair will no longer grow.

Hair removal with the most advanced laser machine. There are many lasers used for hair removal, such as emerald laser, ruby laser, etc. To judge the effect of laser hair removal, on the one hand, it depends on the result (whether the hair is removed completely) and on the other hand, it depends on the process (pain, wound size, etc.). Nano emerald laser machine is the most advanced laser hair removal instrument in China, and the hair removal effect is very satisfactory.

The working principle of nano laser machine is roughly the same as that of general laser machine. Its main advantage is that the laser machine is equipped with cooling device. The cooling device can spray non-toxic refrigerant on the skin surface tens of milliseconds before each laser pulse, which can not only protect the epidermis from burning, but also have a certain analgesic effect. When the nano laser machine is used for treatment, there is only a slight burning sensation, the epidermis is is not damaged, and naturally there will be no scar. After treatment, you can take a bath, live and work as usual.
