Grape Seed
Vitis Vinifera
Rich in polyphenol proanthocyanidins, protects the skin from free radicals and premature aging, increases intracellular vitamin C levels, inhibits destruction of collagen

Does it contain vitamin C, then? Or just cause it to be released into the intracellular space?

Sorry,

Grape seed

It contains Proanthocyanidins which are potent antioxidants. They appear to have a unique ability to increase intracellular Vitamin C levels, as well as scavenge free radicals and delay the destruction of connective tissue. The gallic ester form of proanthocyanidins (the most potent free radical scavengers) are found only in grape seed extract. Some research suggests that this ingredient could also aid in neurological function but that has yet to be conclusive.
