SkinCeuticals Resveratrol B E. Get to know it. You’ve probably read about this latest (and greatist) antioxidant breakthrough in skincare, and I’m here to tell you why it’s a must-have. Resveratrol is a potent antioxidant found in grapes, red wine, nuts, and other plant sources, and has gained a reputation as the “longevity molecule” because of the role it has been found to play in determining longevity and health span. Researchers believe that resveratrol can positively influence the processes that cause age-related deterioration and functional decline. So what does all that mean? SkinCeuticals worked for YEARS to find the right balance for this unstable ingredient since it’s proven to be basic gold for your skin.
