1. Antioxidant effect: Polyphenols in grape seed extract include proanthocyanidins and phenolic hydroxyl groups of gallic acid, which provide hydrogen atoms and have specific and powerful antioxidant effects. The ability to neutralize iron ions and oxygen in attacking lipids is 15 to 25 times that of VB, and its scavenging free radical action is stronger than.
2. anti-inflammatory effect: the main component is proanthocyanidins, its antioxidant activity can inhibit the synthesis and release of inflammatory factors such as histamine, serotonin, prostaglandins and leukotrienes, inhibit the release of basophils and mast cells The granules also inhibit histamine decarboxylase activity and limit the action of hyaluronidase.


Grape seed extract is used in cosmetics to inhibit tyrosinase activity, scavenge free radicals and reduce melanin deposition and dermatitis. It has astringent effect, tightens the skin and prevents the appearance of skin wrinkles. Long-term use can make the skin smooth and rich. Elastic, with the role of beauty and beauty.
