Science
Mechanism of Action
The extract utilizes high concentrations of polyphenols to neutralize oxidative stress and inhibit the production of pro-inflammatory cytokines and nitric oxide. On the skin's surface, it acts as a natural antimicrobial agent, disrupting the proliferation of P. acnes and S. epidermidis while reinforcing the moisture barrier to prevent trans-epidermal water loss.

Key findings
- 01 Demonstrated significant inhibition of Propionibacterium acnes and Staphylococcus epidermidis at MIC levels of 0.16-10.0 microl/ml.
- 02 Identified melanin biosynthesis-inhibitory activity in melanoma cells at concentrations between 10-40 µg/mL.
- 03 Showed dose-dependent reduction in pro-inflammatory markers, indicating strong anti-inflammatory potential.

Dusting Analysis
Due to its efficacy at low MIC levels, many brands include this extract at very low 'label-claim' percentages. For targeted anti-acne or soothing benefits, concentrations should ideally align with levels that mimic clinical MIC values.
The Formula
Formulation
Stability
The extract contains volatile components and polyphenols; stable when formulated in water-based systems, though oxidation protection is recommended.
