Laser hair removal device is a cosmetic instrument that uses laser technology for hair removal. Mainly utilizing the principle of selective photothermal action, laser of a specific wavelength penetrates the surface of the skin and directly acts on the root of hair follicles. Through the conversion of light energy into heat energy, the hair follicle tissue is destroyed, causing it to lose the ability to regenerate hair, thus achieving the effect of hair removal. This hair removal method belongs to permanent hair removal, but requires multiple treatments to achieve complete hair removal.
