Abstract

Claims (28)

1 . A method for biophotonic treatment of a skin disorder, the method comprising:

placing a biophotonic material over a target skin tissue, wherein the biophotonic material comprises at least one chromophore and a cohesive matrix; and

applying light through the biophotonic material, wherein the light has a wavelength that overlaps with an absorption spectrum of the at least one chromophore;

wherein said biophotonic material emits fluorescence that promotes healing of said skin disorder.

2 . The method as defined in claim 1 , wherein the biophotonic material is operatively coupled to a light source.

3 . The method as defined in claim 1 , wherein the biophotonic material functions as a waveguide and transmits light.

4 . The method as defined in claim 1 , wherein the biophotonic material is elastic.

5 . The method as defined in claim 1 , wherein the biophotonic material is rigid or semi-rigid.

6 . The method as defined in claim 1 , wherein the at least one chromophore is a xanthene dye.

7 . The method as defined in claim 6 , wherein the xanthene dye is Eosin Y, Erythrosine B, Fluorescein, Rose Bengal, or Phloxin B.

8 . The method as defined in claim 1 , wherein the cohesive matrix comprises at least one polymer.

9 . The method as defined in claim 8 , wherein the at least one polymer is selected from a cross-linked polyacrylic polymer, a hyaluronate, a hydrated polymer, a hydrophilic polymer and a liposoluble polymer.

10 . The method as defined in claim 1 , wherein the biophotonic material further comprises an oxygen-rich compound.

11 . The method as defined in claim 10 , wherein the oxygen-rich compound is selected from hydrogen peroxide, carbamide peroxide and benzoyl peroxide.

12 . The method as defined in claim 1 , wherein the biophotonic material has a thickness of about 0.1 mm to about 5 mm, about 0.5 mm to about 20 mm, or about 1 mm to about 10 mm.

13 . The method as defined in claim 1 , wherein the biophotonic material comprises one or more waveguide extending at least partially through the biophotonic material.

14 . The method as defined in claim 13 , wherein the one or more waveguide is operatively connected to a light source.

15 . The method as defined in claim 1 , wherein the skin disorder is selected from acne, eczema, psoriasis or dermatitis.

16 . The method as defined in claim 1 , wherein the biophotonic material is peelable and is peeled off.

17 . A method for biophotonic treatment of acne, the method comprising:

placing a biophotonic material over a target skin tissue, wherein the biophotonic material comprises at least one chromophore and a cohesive matrix; and

applying light through the biophotonic material, wherein the light has a wavelength that overlaps with an absorption spectrum of the at least one chromophore;

wherein said biophotonic material emits fluorescence that treats the acne.

18 . A method for promoting skin rejuvenation, the method comprising:

placing a biophotonic material over a target skin tissue, wherein the biophotonic material comprises at least one chromophore and a cohesive matrix; and

applying light through the biophotonic material, wherein the light has a wavelength that overlaps with an absorption spectrum of the at least one chromophore;

wherein said biophotonic material emits fluorescence that promotes skin rejuvenation.

19 . The method as defined in claim 18 , wherein the biophotonic material is a mask.
