1. A method of altering a physical property of a region of skin, comprising:
- applying a therapeutically effective amount of sensitizing light to the region, so that light energy is absorbed by the skin; and
applying a therapeutically effective amount of treatment light to the region, wherein the treatment light is of a wavelength or wavelengths shorter than a wavelength or wavelengths of the sensitizing light;
wherein the application of the effective amount of the sensitizing light enhances an effect of the treatment light in altering the physical property of the region of the skin.

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.

14. A method of altering the appearance of a region of skin, comprising:
-
applying a therapeutically effective amount of light energy to the region of skin wherein the light energy applied has a wavelength of about 695 nanometers to about 1200 nanometers; applying a therapeutically effective amount of intense pulsed light to the region of the skin, wherein the intense pulsed light is applied within minutes of the light energy, wherein the intense pulsed light applied has a wavelength of about 500 nanometers to about 600 nanometers; wherein the application of the light energy and the intense pulsed light results in a change in a physical property of the region of the skin; and wherein the application of light energy results in an erythema of the region of skin that enhances susceptibility of the region of skin to the therapeutically effective amount of intense pulsed light. - View Dependent Claims (15)
