Ellagic acid is an antioxidant found in raspberries, strawberries, cranberries, pomegranates, and an assortment of other fruits, vegetables, and nuts. The study showed that ellagic acid worked to protect against UV damage by blocking the production of MMP (matrix metalloproteinase), an enzyme that breaks down collagen in damaged skin cells and causes coarseness. Ellagic acid also reduces the expression of ICAM, a molecule involved in inflammation.
This study is consistent with the view that topical application of materials containing a variety of berries can be helpful for the skin. This is the basis of the CoffeeBerry product in Stifel’s Revale skin care line since 2006. CoffeeBerry itself is rich in antioxidants and is often recommended over green tea for anti-aging purposes.
Because of ellagic acid’s ability to inhibit skin tumors at various stages their typical life cycle, it may be valuable in cancer therapy or possible prevention in the future. Even if you are feeding your skin a good dose of berries, I wouldn’t skip out on the sunscreen just yet.
