Grape Seed Extract Proanthocyanidins
What is Grape Seed Extract?
Grape seed extract is a natural plant-based active ingredient derived from grape seeds. Its core active substances are proanthocyanidins (OPC) and flavonoids. This extract possesses significant antioxidant capabilities, effectively scavenging free radicals, reducing oxidative stress-induced cell damage, and playing a role in maintaining cardiovascular health by improving vascular elasticity and reducing the risk of lipid peroxidation. In skincare, it can reduce UV-induced skin damage, enhance skin barrier function, and inhibit collagen degradation, thereby helping to delay skin aging and improve skin elasticity and firmness. Furthermore, this ingredient exhibits multiple bioactivities, including anti-inflammatory, immunomodulatory, and potential vision protection activities, and has been widely used in health care, beauty and skincare, and adjunctive medical fields.
