Science
Mechanism of Action
This extract operates through a dual-action pathway: it activates Rho GTPases to drive keratinocyte migration for rapid barrier repair and simultaneously inhibits key inflammatory enzymes—including Phospholipase A2 and Cyclooxygenase (COX)—to halt the production of pro-inflammatory prostaglandins. Its high betulin and lupeol content also provides potent antioxidant activity by neutralizing free radicals and preventing lipid peroxidation at the cellular level.

Key findings
- 01 Concentrations of 5 µg/mL were shown to upregulate IL-6 and IL-8, critical for the inflammatory phase of tissue regeneration.
- 02 An IC50 of 2.4 µg/mL was established for significant antioxidant activity via DPPH radical scavenging.
- 03 Clinical guidelines suggest 0.5% to 2% for localized soothing and anti-inflammatory efficacy in topical applications.
Transparency
Dusting Analysis
While the extract shows bioactivity at very low micro-dosages (µg/mL), topical cosmetic benefits like soothing and antioxidant protection are best realized at concentrations between 0.5% and 2%.
The Formula
Formulation
Stability
The extract exhibits high stability in both aqueous and emulsion systems. While its triterpene components are naturally lipophilic, commercial versions are often standardized in glycerin or butylene glycol for seamless integration.
