How to judge whether it is suitable for laser hair removal

Laser depilation can make your skin more delicate without irritability. But laser hair removal is not suitable for everyone. Let’s see if you are suitable for laser hair removal.

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 layer of the skin and reach the root hair follicle of the hair. The melanin of the hair follicle and hair stem selectively absorbs light energy. The resulting thermal effect destroys the hair follicle without damaging the surrounding tissue, and the pain is slight.

For thicker and darker hair, greater damage will occur after laser treatment, leading to the degeneration and necrosis of some hair follicle cells, so as to effectively prevent hair regeneration for a long time. For thinner and lighter hair, laser treatment can only destroy part of the hair follicle, resulting in the deformation and shrinkage of the hair follicle and accelerating its transformation from growth phase to degenerative phase and quiescent phase, resulting in the shortening and thinning of the hair Lighter colors and significantly slower hair growth. Laser hair removal requires about 3-5 treatments, with an interval of 20-45 days. In addition, the semiconductor laser can make the melanin in the hair follicle be highly selectively absorbed, so as to destroy the hair follicle. This technology is also known as snow depilation.
