Abstract

A method of altering the appearance of a region of skin is disclosed. The method includes applying a sensitizing wavelength of light the region, and applying a treatment wavelength of light to the skin, wherein the treatment wavelength is a shorter wavelength than the sensitizing wavelength. The application of the sensitizing wavelength of light and the treatment wavelength of light results in a change in a physical property of the skin.
