Science
Mechanism of Action
This extract utilizes a high concentration of flavonoids, specifically luteolin, and polyphenols (measured at approximately 7.18 mg GAE/g) to neutralize reactive oxygen species. It functions as a biological shield by inhibiting pro-inflammatory cytokines and suppressing tyrosinase activity, which helps to regulate melanin production and maintain even skin tone.

Key findings
- 01 In vitro analysis confirms high reducing power and potent antioxidant capacity with low hemolytic toxicity (3.8%).
- 02 Comparative ingredient data suggests a 2-5% range for significant skin-conditioning and defensive benefits.
Transparency
Dusting Analysis
Many botanical formulations include this extract at levels below 0.5% for marketing claims ('label dusting'). To achieve documented antioxidant and brightening effects, concentrations should ideally reach the 2% threshold.
The Formula
Formulation
Stability
Aqueous extracts are sensitive to thermal degradation; maintain processing temperatures below 85°C. Storage in light-protected, cool environments is essential to preserve phenolic integrity.
Synergies
- Vitamin E (Tocopherol)
- Glycols
- UV Filters
Conflicts
- Strong oxidizing agents
- Excessive heat
Safety
Safety Profile
While the leaf specifically lacks a standalone CIR monograph, it is structurally similar to the seed and flower extracts which are CIR-approved. It maintains a 'no penalty' safety profile in international regulatory databases.
