Science
Mechanism of Action
It actively scavenges reactive oxygen species (ROS) and inhibits inflammatory mediators like IL-6 and TNF-alpha. Its diarylheptanoids also reduce hyperpigmentation via tyrosinase inhibition and offer photoprotection against UV.

Stability
Stable in O/W emulsions for over 35 days under ambient conditions. Ethanol/ethyl acetate are optimal for extracting UV-protective compounds; water extracts yield polyphenols.
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (may degrade polyphenolic content)
Safety
Safety Profile
Generally regarded as safe for skin conditioning. However, specific dermal toxicity and sensitization studies are limited. It is not listed as a restricted substance by the FDA or EU.
