Resveratrol  is a phytoalexin (trans-3,5,4’-trihydroxystilbene), an antioxidant polyphenol from red wine and recent evidence has supported the assumption that is largely responsible for red wine’s protective effects on blood vessels, by inhibiting lipid peroxidation of low density lipoprotein (LDL). It is found in the skin of red grapes, and is synthesized by the plant in response to attack by pathogens such as bacteria or fungi (especially by the Botrytis fungus). It has been the subject of intense interest in recent years due to a range of unique antiaging properties. The role of resveratrol in prevention of photoaging was reviewed and compared with other antioxidants used in skin care products. It has been clinically proven to have a two-step anti wrinkle activity and also has antiaging activity based on Sirtuin-1 activation.
