Abstract
Peptide-based organic sunscreens, formed by coupling a skin-binding peptide with an organic sunscreen agent, are described. The skin-binding peptide part of the peptide-based organic sunscreen binds strongly to the skin, thus keeping the organic sunscreen agent attached to the skin for long lasting protection. Sunscreen compositions comprising the peptide-based organic sunscreens are also provided.
