Abstract

Disclosed is a system and method for treatment of skin disorders. More particularly, the disclosed invention is directed toward the treatment 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 treatment method of the present invention may be futher 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.

Claims (13)

1. A skin treatment system comprising:

a 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/cm 2 ; and a topical chromophore composition, 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.

2. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a continuous wave having a wavelength of from about 400 mm to about 490 nm.

3. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a continuous wave having a wavelength of from about 560 nm to about 600 mm.

4. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a continuous wave having a wavelength of from about 600 nm to about 650 mm.

5. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a continuous wave having a wavelength of from about 790 nm to about 850 nm.

6. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a series of pulses of light having a wavelength of from about 400 nm to about 490 nm.

7. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a series of pulses of light having a wavelength of from about 560 mm to about 600 mm.

8. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a series of pulses of light having a wavelength of from about 600 nm to about 650 mm.

9. The skin treatment system of claim 1 , wherein the first light source delivers an energy fluence of less than 4 J/cm 2 via a series of pulses of light having a wavelength of from about 790 nm to about 850 nm.

10. The system of claim 1 wherein said topical composition is selected from the group consisting of chlorophyll, porphyrin, carotenoids, bacteriophyll, phycobilins, derivatives thereof, and mixtures thereof.

11. The system of claim 1 further comprising a second light source, wherein said first light source emits radiation having a wavelength between about 300 nm and about 600 nm and said second light source emits radiation having a wavelength between about 600 nm and about 1300 nm.

12. The system of claim 11 wherein said first light source emits wavelength having a dominant emission in the range between about 390 nm and 440 nm and said second light source has a dominant emission in the range between about 590 nm and about 660 nm.
