Laser hair removal works on the principle of selective photothermolysis. The chromophore (melanin) in hair follicles can absorb laser light of a specific wavelength. By targeting melanin, the laser can precisely and selectively perform hair removal treatment, effectively and safely removing hair.
The laser penetrates the skin smoothly to reach the hair follicles. Since hair follicles contain a high concentration of melanin, they preferentially absorb a large amount of laser energy, which is then converted into heat energy. This heat increases the temperature of the hair follicle, ultimately damaging its function. During this process, the skin itself absorbs little to no laser energy, and with the aid of auxiliary facilities and protective measures, the skin remains unharmed.
After a series of treatments, the number of hair follicles decreases, hair growth slows down, and the color of the hair lightens.
