Science
Mechanism of Action
Functions through natural saponins that act as mild surfactants to emulsify sebum and impurities, while tannins provide astringent effects for oil regulation and skin toning. Flavonoids and phenolic compounds deliver antioxidant protection and anti-inflammatory benefits, complemented by organic acids (malic, tartaric, oxalic) that help maintain optimal skin pH and create an environment unfavorable to microbial growth.
Research
Clinical Evidence
Medium confidenceN/A
Key findings
- 01 4% concentration in microemulsions demonstrated maintained antioxidant and anti-tyrosinase activity with improved stability (NIH, 2017)
- 02 Ethanolic extract showed significant wound healing activity through enhanced skin matrix synthesis and reduced inflammatory response (Journal of Pharmacognosy and Phytochemistry, 2023)
Transparency
Dusting Analysis
Limited clinical data available with only one concentration study at 4%, indicating minimal dusting potential due to traditional use patterns rather than cosmetic marketing inflation
The Formula
Formulation
Stability
Stable across pH 3.0-7.0 range but performs optimally at pH 4.5-5.5 for skin compatibility. Highly hygroscopic in powder form requiring moisture protection to prevent clumping.
Conflicts
- strong oxidizing agents
- high alcohol concentrations
Safety
Safety Profile
CIR Expert Panel noted insufficient safety data as of 2010, though extensive traditional use and low reported adverse effects suggest favorable safety profile. May cause dryness at high concentrations.
