Principle:
Laser hair removal based on the principle of selective photothermodynamics, through the reasonable adjustment of laser wavelength, energy, pulse width, the laser will be able to pass through the surface layer of the skin to reach the root of the hair follicle, light energy is absorbed and converted into heat energy to destroy the hair follicle tissues, so as to make the hair lose the regeneration ability, but at the same time do not damage the surrounding tissues, and the pain is slight. Laser hair removal makes use of the laser's "selective photothermal effect", using laser light of a specific wavelength to pass through the epidermis and directly irradiate the hair follicles. The melanin in the hair follicle and hair shaft selectively absorbs the light energy, and the resulting thermal effect causes the hair follicle to become necrotic and the hair to stop growing. The effect of laser hair removal is irreversible due to the process of heat-absorbing necrosis of the hair follicle, therefore, it can achieve permanent depilation effect.

The advantages:
1. It is one of the less painful depilation methods among all methods. The results of many clinical trials show that most patients feel only the feeling of mild warmth.
2. The laser hai removal is very thorough, the use of laser light can penetrate to the deep dermis and subcutaneous fat tissue, the depth of the role of different parts of the hair follicles, to effectively remove the depth of hair in any part of the human body.
3. Laser hair removal will not harm the epidermis.
4. Large spot of the handle can accelerate the speed of treatment.
5. Sapphire contact cooling patented technology safety does not damage the skin,which is the most prominent.
