Science
Mechanism of Action
It functions through a dual-action pathway: first, by upregulating key hydration genes like Aquaporin-3 (AQP3) and Occludin (OCLN) to seal the epidermal barrier; and second, by inhibiting inflammatory enzymes (COX-2) and tyrosinase to promote a calmer, more even-toned complexion.

Key findings
- 01 In vivo testing demonstrated a 48.6% increase in skin hydration within one hour of application, maintaining a 34.2% increase after 24 hours.
- 02 A 4-week clinical trial confirmed significant reductions in skin roughness and desquamation when applied twice daily.

Dusting Analysis
While often included in botanical blends for marketing purposes at trace amounts, clinical benefits for barrier repair and hydration require a minimum concentration of 1-2%.
The Formula
Formulation
Stability
Highly robust across a wide pH range; its lipophilic nature requires integration into the oil phase or high-quality solubilizers in water-based serums.
