It uses the working principle of photothermal dynamics. The laser beam passes through the epidermis and enters the hair follicle roots. The pigments in the hair follicles absorb the light and convert it into heat, destroying the hair during the hair growth phase while leaving the surrounding skin undamaged.

The remaining hair after 808nm laser treatment will become finer and lighter in color, and will not become darker. On the other hand, methods such as shaving, plucking, depilatory creams, and waxing can cause the hair to gradually become thicker, harder, and darker if used for a long time.

There is no damage. You can rest assured. The working principle of laser hair removal is based on selective photothermal action: specifically, the 808nm wavelength targets only the melanin in the hair follicles and does not affect the normal skin tissue. (In other words, the 808nm wavelength light only absorbs melanin in the hair follicle, and there is no melanin in the surrounding skin, so there is no harm.)
