Abstract

A composition includes polydatin and at least one photoisomerization stabilizer and cosmetically acceptable carrier. The at least one photoisomerization stabilizer confers photostabilization to trans-polydatin by at least about 5%, relative to an otherwise identical composition without the at least one photoisomerization stabilizer.
