Free-radical scavenging is the claim often associated with resveratrol and antioxidants in general. In topical application, the free-radical scavenging effect can prevent the signs of aging and help protect skin from environmental stressors, such as pollution and the sun.
Anti-inflammatory, skin-brightening and collagen-promotion effects have also been associated with resveratrol. Regarding skin brightening, some research has suggested that resveratrol is able to downregulate key steps in melanin production. Meanwhile, others have found that the ingredient inhibits the expression of inflammatory enzymes and promotes collagen synthesis.
"Sirtuins" have been the recent buzzword surrounding resveratrol. Sirtuins are thought to extend the life of mitochondria, thereby preventing cellular damage. If resveratrol does activate sirtuins, it may also have an anti-aging effect that extends beyond its antioxidant and collagen-promoting benefits.
