Science
Mechanism of Action
The extract operates through a dense concentration of condensed tannins and catechins which neutralize oxidative stress and inhibit enzymatic degradation of collagen and elastin. Additionally, its selenium and gallic acid content supports cellular DNA repair mechanisms and reduces pro-inflammatory cytokines to soothe reactive skin.

Key findings
- 01 In vitro analysis demonstrated a 33-37% inhibition of elastase and collagenase enzymes, directly preserving skin elasticity.
- 02 Cell culture studies at 1.3% concentration showed significant inhibition of degranulation, indicating strong anti-allergic potential.
- 03 Radical scavenging assays confirmed antioxidant activity levels between 46% and 82%.

Dusting Analysis
Because it is a recognizable botanical, it is often included at negligible concentrations (0.1% or less) for 'label claims.' Formulations require at least 0.5% to trigger its enzymatic inhibition benefits.
The Formula
Formulation
Stability
Highly stable up to 240°C in its raw form; however, in finished emulsions, it remains most stable in slightly acidic environments to prevent the oxidation of its polyphenol content.
Synergies
