Science
Mechanism of Action
This ingredient operates through several key pathways. Its high concentration of polyphenols provides robust antioxidant defense, comparable to Vitamin C, neutralizing free radicals and mitigating oxidative stress. Polysaccharides reinforce the skin's extracellular matrix, promoting structural integrity, while fatty acids contribute anti-inflammatory effects. Crucially, it stimulates de novo collagen synthesis and simultaneously inhibits collagenase activity and MMP-1 synthesis, thereby preserving the skin's youthful firmness and elasticity. Furthermore, it fortifies the skin barrier by upregulating epidermal proteins and modulates immune responses by reducing IgE levels, offering significant anti-allergic potential and enhancing skin's overall protective capacity against environmental aggressors, including UVB-induced damage.
