Abstract
A light based treatment method and apparatus removes unwanted hair from a target region of skin. The treatment method uses multiple wavelength bands of light or radiation. The ratio of the energies of the wavelength bands is selected according to a skin parameter, e.g., skin type, which can be differentiated by the amount of melanin in the skin. The treatment method can provide safe and effective permanent hair removal for any skin type.
