Science
Mechanism of Action
This extract operates through a four-tiered approach: it protects elastin from enzymatic breakdown via anti-elastase activity, prevents glycation-induced stiffness, neutralizes reactive oxygen species through its gallic acid content, and modulates melanogenesis by inhibiting tyrosinase and the MITF pathway.

Key findings
- 01 Achieved >80% inhibition of elastase activity, indicating significant preservation of dermal elasticity and wrinkle prevention.
- 02 Isolated ethyl gallate within the extract effectively suppressed melanin production by downregulating key genetic markers without compromising cell viability.

Dusting Analysis
Because it is an exotic botanical, many brands include it at 'label-claim' levels (below 0.01%). However, clinical data suggests that concentrations near 0.1% are required to unlock its potent anti-elastase and skin-firming benefits.
The Formula
Formulation
Stability
Highly stable in water-based systems but sensitive to temperatures exceeding 40°C. Due to its tannin profile, it is prone to oxidation and discoloration if exposed to prolonged UV light.
