FUNCTION

Ultimate Free Radical Scavenging & Cellular Defense

Possesses an extraordinary antioxidant capacity that is scientifically verified to be 50 times more potent than Vitamin E and 20 times stronger than Vitamin C. This ultra-dense polyphenol profile dynamically neutralizes reactive oxygen species (ROS), protecting delicate cellular membranes and DNA strands from premature oxidative degradation.

Dermal Collagen Protection & Skin Brightening

Actively binds to natural collagen and elastin fibers, shielding them from enzymatic breakdown caused by UV radiation and environmental pollution. Simultaneously, its highly bioactive OPCs inhibit intra-cutaneous tyrosinase activity, effectively fading hyperpigmentation and yielding a brilliant, luminous complexion.

Endothelial Strength & Cardiovascular Optimization

Upregulates endothelial nitric oxide synthase (eNOS), which actively promotes smooth vasodilation and improves arterial elasticity. Clinical trials repeatedly confirm its ability to reduce blood viscosity, safeguard microcapillary integrity, and provide robust systemic protection against lower-extremity edema and chronic venous stress.

Anti-Inflammatory Modulation & Metabolic Balance

Helps suppress the expression of pro-inflammatory enzymes such as COX-2 and iNOS, effectively lowering systemic inflammatory markers. This multi-targeted botanical pathway assists in reducing metabolic cell stress, optimizing lipid profiles, and safeguarding overall cardiovascular and joint tissue longevity.

Application

Nutricosmetics & Ingestible Skin Brightening

The unmatched foundational active ingredient for anti-aging capsules, skin-whitening tablets, and beauty-from-within softgels. It pairs with exceptional commercial synergy alongside Glutathione, Collagen Peptides, Vitamin C, or Coenzyme Q10 to dominate the high-premium global skin-wellness retail sector.

Cardiovascular & Capillary Health Complexes

Highly utilized in heavy-duty blood pressure support formulas, anti-fatigue supplements, and senior vascular mobility pills. Its proven capacity to strengthen blood vessels makes it a top-tier choice for formulators looking to target varicose veins, microvascular fragility, and deep tissue circulation health.

Anti-Glycation Beauty Gummies & Jellies

An excellent active inclusion for premium, pectin-based functional gummies, collagen jellies, and beauty confectionery shots. Because its localized polyphenols are clinically proven to drastically inhibit advanced glycation end-products (AGEs) that cause skin sagging, it empowers functional food brands to capture younger consumer demographics looking for delicious, pill-free anti-glycation solutions.

Clean-Beauty Skincare & Topical Formulations

Extensively utilized as a core functional botanical additive in high-end anti-pollution serums, protective day creams, and reviving eye treatments. Our highly purified, water-soluble formulation dissolves instantly without grittiness or undesirable precipitation, allowing cosmetic R&D teams to deliver a pure, non-irritating skin barrier shield.
