Science
Mechanism of Action
This extract operates primarily as a natural lipase inhibitor, specifically blocking P. acnes lipase to prevent the conversion of triglycerides into irritating free fatty acids, thereby reducing surface inflammation. Furthermore, it acts as a radical scavenger that inhibits MMP-1 (collagenase) enzymes and stimulates hyaluronic acid synthesis to preserve the extracellular matrix.

Key findings
- 01 Human trials confirmed significant skin-smoothing benefits and a complete absence of irritation when applied topically in a cream base.
- 02 In-vitro testing demonstrated potent anti-wrinkle and antioxidant activity comparable to leading botanical benchmarks, specifically targeting free radical scavenging.

Dusting Analysis
While significant biological activity (antioxidant) is noted at very low concentrations in-vitro, the skin-smoothing and lipase-inhibiting benefits observed in human applications typically require concentrations between 2% and 6%. Formulations containing less than 0.5% are likely using it for label claims rather than therapeutic efficacy.
The Formula
Formulation
Stability
Polyphenolic compounds are stable within a slightly acidic range; environments with a pH above 7.0 can trigger oxidation and undesirable darkening of the extract.
Synergies
- Hyaluronic Acid
- Niacinamide
- Vitamin E
Conflicts
- Strong oxidizing agents
- Iron salts
- High pH alkaline bases
Safety
Safety Profile
While not yet formally reviewed by the CIR, it has a long history of use in traditional medicine and is listed in the IECIC. Sensitization risk is low provided the extract is purified to remove residual anthraquinones.
