Resveratrol offers a powerful and scientifically-backed ingredient that can help rejuvenate and energize skin. Research suggests resveratrol may help reduce the intensity of age spots, improve skin elasticity and hydration, and protect against oxidative damage. In one clinical trial resveratrol was found to reduce the expression of certain pro-inflammatory cytokine genes. These genes are thought to be of major importance in the development of psoriasis. Research suggests that resveratrol may also help skin complaints such as mild acne.
