System and method for the photodynamic treatment of burns, wounds, and related skin disorders

Abstract

A method including photomodulating mammalian tissue with more than one light source of narrowband, multi chromatic electromagnetic radiation, wherein at least one light source emits radiation at a wavelength corresponding to yellow light and at least one light source emits radiation corresponding to infra-red light, wherein the ratio of the intensity of yellow light to infra-red light is about 4:1.
