Laser hair removal is based on the principle of selective photothermodynamics. By reasonably adjusting the wavelength, energy and pulse width of the laser, the laser can pass through the skin surface to reach the hair follicle at the root of the hair, and the melanin in the hair follicle and hair shaft selectively absorbs light energy.  the resulting thermal effect destroys the hair follicle without damaging the surrounding tissue, and the pain is mild.

For thicker and darker hair, after laser treatment, greater damage will occur, resulting in the degeneration and necrosis of some hair follicle cells, thereby effectively preventing hair regeneration for a long time. For finer and lighter hair, after laser treatment, only At the same time, the partial destruction of the hair follicle causes the deformation and shrinkage of the hair follicle and accelerates its transition from the anagen phase to the anagen phase and telogen phase, resulting in shorter, thinner, lighter hair and significantly slower hair growth. Laser hair removal requires about 3-5 treatments, with an interval of 20-45 days between treatments. Another semiconductor laser can make the melanin in the hair follicle be highly selectively absorbed, thereby destroying the hair follicle.

This technology is also known as snow skin hair removal.

1. People who are suitable for hair removal

Laser hair removal works on all parts of dark and light hair, but not on white hair. Laser hair removal is suitable for almost all people, and the scope of application is very wide, whether it is limb hair, hairline, eyebrows, lip hair, armpit hair, pubic hair, etc., can be used. As long as people who can do photon beauty are basically suitable for laser hair removal.

2. Those who are contraindicated in laser hair removal

1. Those with allergies or scars.

2. Those suffering from hepatitis, syphilis, and skin infections.

3. Blood diseases and coagulation disorders.

4. Menstruating women. "
