Optically-activated systems and methods for reducing the appearance of dark under eye circles are provided. The systems comprise a complex of a fluorescent compound and a substrate for the fluorescent compound which are affixed to one another by covalent bonding, hydrogen bonding, Van der Waals forces, or a combination thereof. After absorption of ambient light, the fluorescent compound in the complex re-emits visible light of longer wavelength. The re-emitted light provides an illuminating radiant effect and is particularly useful in improving the appearance of skin imperfections.

1. An optically-activated system comprising a complex of riboflavin and at least one substrate for the riboflavin wherein the riboflavin is affixed to the at least one substrate for the riboflavin by covalent bonding, hydrogen bonding, Van der Waals forces, or a combination thereof, wherein the at l
1. An optically-activated system comprising a complex of riboflavin and at least one substrate for the riboflavin wherein the riboflavin is affixed to the at least one substrate for the riboflavin by covalent bonding, hydrogen bonding, Van der Waals forces, or a combination thereof, wherein the at least one substrate for the riboflavin comprises hyaluronic acid (HA), wherein the complex is in the form of a gel, and wherein the riboflavin in the complex is continually activated in the presence of ambient light and emits fluorescent light. 2. The optically-activated system of claim 1, wherein the gel thus-produced is further absorbed into pores of at least one porous substrate. 3. The optically-activated system of claim 2, wherein the porous substrate is selected from the group consisting of a polyacrylic acid or a salt thereof; an isoprene derivative; a polyamide or a derivative thereof; polyvinyl chloride (PVC); polyvinyl dichloride (PVDC); a silicone polymer; a polyester; and a polyurethane. 4. The optically-activated system of claim 3, wherein the salt of the polyacrylic acid is poly (methyl) methacrylate (PMMA) or polyhydroxyethyl methacrylate (pHEMA); the isoprene derivative is isoprene maleate polyethylene glycol (PEG); and the polyamide is nylon. 5. The optically-activated system of claim 2, wherein the complex is selected from the group consisting of riboflavin, HA and nylon; and riboflavin, HA and PMMA combination. 6. The optically-activated system of claim 1, wherein the riboflavin is present in the system in amounts in the range of from about 0.001% to about 2%, by total weight of the system. 7. The optically-activated system of claim 1, wherein the at least one substrate for the riboflavin is present in the system in amounts in the range of from about 0.05% to about 25%, by total weight of the system. 8. The optically-activated system of claim 1, wherein the complex is present in the system in amounts in the range of from about 0.1% to about 20%, by total weight of the system. 9. The optically-activated system of claim 1, wherein the optically-activated system comprises at least one further fluorescent compound which is not affixed to the substrate. 10. The optically-activated system of claim 1, further comprising at least one optically reflective or light scattering material. 11. The optically-activated system of claim 10, wherein the at least one optically reflective or light scattering material is selected from the group consisting of mica-based materials, glass-based materials or plastic-based materials, and combinations thereof. 12. The optically-activated system of claim 11, wherein the at least one optically reflective or light scattering material is selected from the group consisting of iridescent/pearlescent materials and soft focus materials, wherein the iridescent/pearlescent materials reflect light in the green region of the electromagnetic spectrum. 13. A cosmetic composition for improving the appearance of at least one skin imperfection selected from the group consisting of dark under eye circles, hyperpigmentation, rosacea, lines, wrinkles, enlarged pores and cellulite, said composition comprising the optically-activated system of claim 1 and a cosmetically acceptable vehicle. 14. A cosmetic composition for improving the appearance of at least one skin imperfection selected from the group consisting of dark under eye circles, hyperpigmentation, rosacea, lines, wrinkles, enlarged pores and cellulite, said composition comprising the optically-activated system of claim 10 and a cosmetically acceptable vehicle. 15. The optically-activated system of claim 1, wherein the optically-activated system emits green fluorescent light.
