Grape Seed

Grape seed is extracted from Vitis vinifera and is rich in proanthocyanidins, which belong to the flavonoid family. Proanthocyanidins are potent antioxidants with strong free radical scavenging activities.[47] Grape seed extract has been shown to be an even stronger scavenger of free radicals than vitamins C and E.[48] A possible antioxidant mechanism of photoprotection by grape seed proanthocyanidins (GSP) was suggested by Mittal, et al.[49] GSP was shown to inhibit the depletion of antioxidant defense components induced by UVB,[50] and topical application of grape seed extract seems to enhance the sun protection factor in humans.[43] It is included in topical cosmetic formulations for antiaging purposes.
