Laser hair removal is currently the most safe, fast and lasting hair removal technology.
principle
Laser hair removal is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength, energy and pulse width, the laser can pass through the surface of the skin to reach the root hair follicle of the hair. The light energy is absorbed and converted into the heat energy that destroys the hair follicle tissue, so that the hair can lose its regeneration ability without damaging the surrounding tissues, and the pain is slight. In addition, laser hair removal makes use of the “selective photothermal effect” of laser, which uses a laser tuned to a specific wavelength to pass through the epidermis and directly irradiate the hair follicle. The melanin of hair follicle and hair shaft selectively absorbs light energy, and the resulting thermal effect causes hair follicle necrosis and hair no longer grows. As the process of heat absorption necrosis of hair follicle is irreversible, laser hair removal can achieve the effect of permanent hair removal.
advantage
1. The results of many clinical trials show that most of the patients’ feelings are just the feeling of “being bounced by the rubber band”.
2. The advantage of laser hair removal is that the hair is completely removed. The laser can penetrate into the deep dermis and subcutaneous fat tissue, and act on the deep hair follicles of different parts to effectively remove the deep hair of any part of the human body.
3. The advantage of laser hair removal is that it will not harm the epidermis, the skin, and the perspiration function. It can effectively protect the skin from being damaged by heat. [1]
4. The advantage of laser hair removal is that the pigment precipitation after hair removal is very close to our skin.
5. The advantage of laser hair removal is fast.
Features
1. The best wavelength is used for treatment: the laser can be fully absorbed selectively by melanin, and the laser can effectively penetrate the skin to reach the location of hair follicles. The role of laser is effectively reflected in the generation of heat on melanin in hair follicles to remove hair.
2. For the best hair removal effect, the required laser pulse time is related to the thickness of the hair. The thicker the hair, the longer the laser action time is required, which can achieve the ideal effect without damaging the skin.
3. Laser hair removal does not produce pigment precipitation on the skin surface after hair removal like traditional hair removal methods. This is because the skin absorbs less laser during laser hair removal.
4. The use of the cooling system can effectively protect the skin from the laser burn in the whole process.
