Method of making an optically-activated system
First Claim
1. A method of making an optically-activated system comprising a complex of riboflavin and at least one substrate for the riboflavin, said method comprising affixing the riboflavin to the at least one substrate for the riboflavin by covalent bonding, hydrogen bonding, Van der Waals forces, or a combination thereof, wherein the riboflavin in the complex is continually activated by absorption of ambient light and re-emits fluorescent visible light of longer wavelength in the yellow-green region of the electromagnetic spectrum.

Abstract
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.
