Overview

Grape Seed Extract is derived from the seeds of red wine grapes. It is a rich source of Oligomeric Proanthocyanidin Complexes (OPCs), which are powerful antioxidants. OPCs are known for their ability to protect collagen and elastin from degradation by free radicals and enzymes. This helps to maintain the structural integrity of the skin, improving firmness, elasticity, and reducing the signs of aging. OPCs also have strong anti-inflammatory properties and can improve blood circulation to the skin.
