What it is
Vitis vinifera (wine) extract is obtained from grapes, the fruit of the common grapevine used in winemaking. Grapes and their byproducts are rich in polyphenols such as resveratrol and other antioxidants, which is the basis for the extract's use in cosmetics. In sunscreens it is added at low levels as a conditioning and antioxidant component supporting the formula.
