Science
Mechanism of Action
Operates through a dual-action pathway: it serves as a biological shield by downregulating the CYP1A1 protein—a primary marker of pollution-induced stress—and functions as an antioxidant scavenger that neutralizes reactive oxygen species (ROS). Additionally, it inhibits MMP-1 enzymes to prevent collagen degradation while suppressing pro-inflammatory cytokines triggered by UV exposure.

Key findings
- 01 Demonstrated significant reduction in CYP1A1 expression and ROS production caused by PM2.5 particulate matter at concentrations of 1.0-3.0%.
- 02 Confirmed high DPPH radical scavenging capacity and inhibition of collagenase (MMP-1) at 2.0% for anti-aging and barrier support.
Transparency
Dusting Analysis
While frequently listed in botanical-heavy ingredient decks for marketing appeal, concentrations below 1% are unlikely to provide the anti-pollution and enzyme-inhibiting benefits validated in clinical trials.
The Formula
Formulation
Stability
Thermolabile ingredient; must be incorporated during the cooling phase at temperatures below 40°C. Susceptible to photo-degradation and slight discoloration if exposed to consistent light.
Synergies
