Grape Seed Extract 95% OPC Procyanidine
The main component of grape seed extract is proanthocyanidin, which is a new type of highly effective natural antioxidant that can not be synthesized from grape seeds. It is one of the most efficient antioxidants found in plants to date. In vivo and in vitro tests have shown The antioxidant effect of grape seed extract is 50 times stronger than vitamin E and 20 times stronger than vitamin C. It can effectively remove excess free radicals in the human body and has a strong anti-aging effect and enhance immunity. The main effects are anti-inflammatory, anti-histamine, anti-allergic, anti-allergic, anti-oxidation, anti-fatigue enhance physical fitness, improve sub-health state, delay aging, improve irritability, dizziness, fatigue, memory loss symptoms, beauty, promote blood Loop and so on.

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.
