Science
Mechanism of Action
Operates as a potent protease inhibitor that specifically targets neutrophil elastase and collagenase, preventing the degradation of the dermal extracellular matrix. Its high concentration of catechins and procyanidins provides superoxide dismutase (SOD)-like activity, neutralizing oxidative stress while downregulating inflammatory markers.

Key findings
- 01 In vitro assays (2022) demonstrated an 80% inhibitory concentration (IC80) against elastase at a dilution of 0.022%, highlighting extreme potency in preserving skin elasticity.
- 02 Patent data (KR101143717B1) establishes that concentrations between 0.1% and 5% are effective for topical anti-inflammatory, moisturizing, and skin-soothing applications.

Dusting Analysis
Because this extract shows biochemical activity at concentrations as low as 0.022%, it is frequently 'dusted' into formulations at negligible amounts to claim anti-aging benefits. For measurable soothing and barrier support, levels above 0.1% are required.
The Formula
Formulation
Stability
Heat-sensitive; must be incorporated during the cool-down phase (below 50°C) to prevent the thermal degradation of its polyphenol content. Most stable in hydro-glycolic or purely aqueous systems.
Synergies
- Hyaluronic Acid
- L-Ascorbic Acid
- Niacinamide
Conflicts
- Strong oxidizing agents
- High-heat processing
Safety
Safety Profile
Generally regarded as safe; as a callus culture, it typically offers higher purity and fewer environmental contaminants (like pesticides) compared to traditional field-grown extracts.
