The harm of laser hair removal

Principle of hair removal

Laser hair removal is not harmful to the body, laser hair removal is based on the principle of selective photothermodynamics, through the reasonable adjustment of laser wavelength energy pulse width, laser can pass through the skin surface to the hair root hair follicle, light energy is absorbed and converted into the destruction of hair follicle tissue heat energy, so that the hair loses the ability to regenerate without damaging the surrounding tissue, so as to achieve permanent hair removal effect. Permanent hair removal destroys hair follicles so that hair no longer grows. It does not destroy sweat glands, which are two separate tissues, so it has no effect on perspiration.
