Science
Mechanism of Action
The key active component, escin, functions as a venotonic agent that fortifies capillaries and decreases permeability by inhibiting enzymes like hyaluronidase and collagenase, thereby preventing fluid leakage and reducing redness. Additionally, it stimulates fibroblast contraction to enhance skin elasticity and provides robust antioxidant activity by scavenging active oxygen species.
