Abstract
Disclosed is a system and method for treating and preventing skin disorders. More particularly, the disclosed invention is directed toward the prevention of acne and acne scarring by treating sebaceous oil glands and the surrounding tissue with an exogenous chromophore composition and then exposing the target tissue to visible, infrared, or ultraviolet light to inhibit the activity of the oil gland and eliminate acne bacteria. The method of the present invention may be further augmented by enhancing the penetration of the topical composition into the oil gland and surrounding tissue through the use of procedures including enzyme peeling, microderm abrasion, or ultrasound.
Claims9
An acne prevention method comprising:
- exposing tissue to a first light source, the first light source comprising light emitting diodes emitting light at a wavelength of from about 300 nm to about 1300 nm and a total energy fluence of less than 4 J/cm2;
- and applying a topical chromophore composition to the tissue either before or after exposing the tissue to electromagnetic radiation, wherein the topical chromophore composition has at least one absorption maximum between 300 nm and 1300 nm and comprises an active ingredient selected from the group consisting of chlorophyll, porphyrin, and combinations thereof, wherein the active ingredient has at least one metal-ligand bond, wherein the metal in the metal-ligand bond is selected from the group consisting of Fe, Mg, Cu, Al, reactive transition metals, metal chelates, and antibody complexes.
