Grape extract contains chemical constituents such as proanthocyanidins, polyphenols, flavonoids, and anthocyanins, all of which are very potent antioxidants. Grape extract has also been shown to have wound-healing properties.
When combined with other antioxidants, it reduces biomarkers in skin that are responsible for skin cancer. Red grapes contain resveratrol. Resveratrol is considered a very potent antioxidant and is believed to be the component responsible for the health benefits of red wine (and grape juice).
Topical application of grapeseed extract to a cultured human skin equivalent showed evidence of younger skin, including enhanced synthesis of healthy collagen, elastin, and improvement in many other structural components of skin.
