Grape (Vitis vinifera) extracts, including seed and skin derivatives, are rich in polyphenols such as resveratrol and proanthocyanidins that provide antioxidant and free-radical scavenging benefits in topical formulations. They are used to help protect skin from oxidative stress and support overall skin condition.
