808nm laser chip application case-semiconductor laser hair removal

Oct 15, 2021

With the development of semiconductor laser technology, products using GMKJ 808nm SMD LED as the core device have shown many advantages, and at the same time, they have increasingly won the recognition and favor of global consumers in the field of laser beauty. At present, the mainstream hair removal equipment in the market uses 808nm laser as the core device.


1. The best wavelength is used for treatment: the laser can be completely absorbed by melanin, and the laser can effectively penetrate the skin to reach the position of the hair follicle. The effect of the laser is effectively reflected in the melanin in the hair follicles to generate heat for hair removal.

2. The best hair removal effect depends on the thickness of the hair. The thicker the hair, the longer the laser action time is, and the desired effect can be achieved without damaging the skin.

3. Laser hair removal is not like traditional hair removal methods, which produce pigmentation on the skin surface after hair removal. This is because the skin absorbs less laser light when laser hair removal occurs.

4. The use of the cooling system can effectively protect the skin from laser burns during the entire process.

Treatment range Laser hair removal is suitable for dark and light-colored hair on various parts of the body, and excess black hair on various parts of the body (upper and lower limbs, legs, chest, abdomen, hairline, facial beard, bikini line). Hair removal devices such as electric acupuncture, drugs, and electric forceps are all ineffective or fail.

Factors affecting the results of hair removal:

1. Different laser hair removal effects of the device are also different. In terms of equipment, different treatment equipment have different effects. The 808 semiconductor laser light source has a great influence on the hair removal effect. In other words, some instruments with higher light source intensity have better therapeutic effects than instruments with lower light source intensity.

2. Physical differences will also affect the effect of laser hair removal. Everyone's physique is different, hair density and growth ability are also different, and the effect of hair removal is also different, so different people use the same hair removal method, some sensitive people. They may be able to remove it all at once, while other insensitive people may have to remove it multiple times to achieve some results.

3. Different colors of skin and hair will cause different laser hair removal effects. The difference in skin color and hair color will vary during treatment. Because the 808 semiconductor laser treatment is very selective, it is determined according to the pigmentation in the skin, that is, the hair follicles in different parts are related to laser hair removal. In the same individual, different parts of the hair removal effect are also different.
