ABSTRACT:
The present invention provides a method for removing hair from a selected skin area comprising the steps of (a) applying a liposome composition comprising a photosensitizer to the selected skin area so that the composition is introduced into hair follicle ducts of the skin area, wherein the photosensitizer is present in the composition in an amount effective to undergo a reaction and damage the hair follicles upon application to the skin area of light at an appropriate wavelength, energy and duration to penetrate the skin and activate the photosensitizer; (b) removing from the skin area substantially all of the liposome composition which is not introduced into the hair follicle ducts; and (c) applying light to the skin area at an appropriate wavelength, energy and duration to penetrate the skin and cause the photosensitizer to undergo a reaction to damage the hair follicles. The present invention also provides a composition useful for hair removal.
