Evaluating Essential Oils in Cosmetics: Antioxidant Capacity and Functionality

The Photostability and Photostabilization of trans-Resveratrol

In this study, the effects of ultraviolet radiation (UVR) on trans-resveratrol were documented, finding that UV radiation causes it to undergo rapid and extensive photoisomerization and some photodecomposition. The antioxidant activity of trans-resveratrol is correspondingly reduced. However, in the presence of ethylhexyl methoxycrylene, a photostabilizer used in sunscreens, the effects of UV exposure on trans-resveratrol are minimized, thereby preserving its antioxidant activity and, presumably, its bioavailability.
