Science
Mechanism of Action
This extract operates through a dual-pathway system: first, its high concentration of phenolic compounds and flavonoids (notably rutin) scavenges free radicals to prevent cellular damage; second, it functions as an enzymatic inhibitor, specifically targeting collagenase and hyaluronidase to stop the degradation of collagen and hyaluronic acid. Additionally, its polysaccharide content enhances the skin's osmotic pressure, improving long-term moisture retention.

Key findings
- 01 In-vitro analysis (2025) demonstrated an 86.5% to 87.87% radical scavenging activity at a concentration of 100 µg/mL, performing comparably to high-grade ascorbic acid.
- 02 Research published in Molecules (2021) confirmed DPPH and ABTS radical scavenging capacity at 0.1 mg/mL, establishing its role as a preventative antioxidant.
- 03 Historical data from the NMPA (2021) validates its safety and efficacy in leave-on formulations at levels up to 2.4%.
Transparency
Dusting Analysis
Due to its botanical origin, it is frequently used at trace amounts (under 0.1%) for marketing purposes. To achieve the documented antioxidant activity and enzyme inhibition observed in clinical settings, concentrations between 1.0% and 2.4% are recommended.
The Formula
Formulation
Stability
Naturally exhibits a slightly acidic to neutral pH (6.09-6.6). While stable at room temperature, it is susceptible to photo-degradation and should be stored in UV-protective packaging.
Synergies
- Vitamin C (to stabilize the antioxidant network)
- Hyaluronic Acid (to enhance the effects of hyaluronidase inhibition)
- Tocopherol (to protect the lipid-phase from oxidation)
Conflicts
- High-heat processing (may degrade phenolic content)
- Highly oxidative environments without secondary stabilizers
Safety
Safety Profile
HET-CAM testing indicates a non-irritating profile. It is currently listed as a safe-grade cosmetic ingredient with an established FDA UNII code (0EFG08DK6K).
