Versatile Resveratrol Part 2: The ultimate skin care ingredient?

What would the ideal anti-aging skin care product look like? To begin with, it would need to provide protection against sun damage from UV exposure . [i] Of course any sunscreen does that, so what we really want is something that can help reverse the effects of UV exposure, which include mutations in the DNA of skin cells. This is where the idea of working at a molecular level comes into play. While many products talk about “DNA repair” the evidence for a role for resveratrol is particularly strong. There are several ways that resveratrol functions in this regard, the best known of which is its powerful antioxidant effects. Healthier DNA means not only more attractive skin but a lower risk of skin cancers . The use of antioxidants such as resveratrol to lower risk of skin cancer is known as chemoprevention. There is evidence that it may help prevent many other types of cancer as well. Another measure of aging has to do with integrity of sequences on the ends of the chromosom

Versatile resveratrol: the ultimate skin care ingredient?

  Part 1 Recently I was honored to join Professors David Sinclair of Harvard and Joseph Vercauteren of the University of Montpelleir at an anti-aging symposium at the invitation of Mathilde Thomas of Caudalie in Paris. Caudalie has been using wine extracts (and specifically resveratrol) in their products for more than 15 years, after Vercauteren identified it in wine grape vines. Sinclair has become well known for his work identifying the role of sirtuin (SIRT) genes in anti-aging, and resveratrol as a natural sirtuin activator. While much remains to be proven, it is fair to say that science is finally beginning to have an impact on skin care. With an increasing understanding of what causes aging in skin cells and how botanical antioxidants such as resveratrol work at a molecular level, there is no excuse to use anti-aging skin care products that don’t multitask. Before delving into the potential benefits of resveratrol in skin care, it may help to review how resveratrol
