Science
Mechanism of Action
This extract operates through a multi-pathway antioxidant approach, utilizing flavonoids like quercetin and gallic acid to donate protons to free radicals, thereby halting the chain reaction of lipid peroxidation. Simultaneously, its phytochemical profile provides anti-inflammatory benefits by suppressing prostaglandin synthesis and offers antimicrobial protection by compromising the structural integrity of bacterial cell walls.

Dusting Analysis
While this extract shows significant antioxidant preservation at levels as low as 0.2%, it is frequently included in formulas at symbolic concentrations (below 0.1%) where its biological impact on the skin is negligible. To reach the documented antimicrobial and therapeutic thresholds, levels closer to 0.5% or higher are required.
