Grape Seed Extract

Vitis Vinifera (Grape) Seed Extract · Vitis Vinifera Seed Extract

An extract from the wine grape, Vitis vinifera. Little research tests what it does on skin.

What it does

It’s an extract of wine grape seeds. The EU lists it as an antioxidant, which in a formula means slowing the reactions with air that spoil it, and as a skin protectant.

The EU’s ingredient database lists it as an antioxidant (slows reactions with oxygen, like going rancid) and a UV absorber (protects the product from UV light, not your skin).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗

The evidence, graded

expert consensusUS safety reviewers (2014) judged 24 grape-derived ingredients safe as used, grape seed, leaf and juice extract among them. In tests on people, products with 0.5% juice extract, and seed extract at up to 1% of a raw material, didn’t irritate or cause allergy. They treated one rabbit test of undiluted seed extract, which found moderate irritation, as an outlier. Grape ingredients don’t appear to irritate or cause allergy, they said, and makers should limit pesticides and heavy metals.Fiume 2014 · International Journal of Toxicology ↗
