Products Description
Grape Seed Extract is a polyphenolic material derived from natural grape seeds. Its primary active ingredient is oligomeric proanthocyanidins, commonly known as OPC, a low‑molecular‑weight proanthocyanidin polymer. It ranks among the most potent plant‑sourced natural antioxidants known so far. It exhibits remarkable free‑radical scavenging capacity; both in‑vivo and in‑vitro tests demonstrate that its antioxidant activity is roughly 20 times higher than vitamin C and 50 times greater than vitamin E.

Products Application
Grape Seed Extract delivers powerful antioxidant, anti‑allergic, anti‑fatigue, immunity‑boosting and anti‑inflammatory properties. It helps improve sub‑health status, and clinical studies have revealed its potential for the prevention and adjunct treatment of high cholesterol, atherosclerosis and gastric ulcers. Well‑known in Europe as “oral skin cosmetics”, this ingredient effectively safeguards skin collagen and elastic fibers, shields skin against UV‑induced damage and lessens melanin deposition, thereby achieving anti‑aging and skin‑beautifying effects. Acting as a natural antioxidant and preservative, it is widely incorporated into cakes, cheese, beverages, health supplements and other products as an alternative to synthetic preservatives. Furthermore, it serves as an antioxidant, skin conditioning agent and UV‑absorbing component in a broad range of skincare and personal‑care formulations.
