Science
Mechanism of Action
This botanical agent operates through four primary pathways: it inhibits the MMP-1 enzyme to prevent collagen breakdown, neutralizes reactive oxygen species (ROS) via high phenolic content, suppresses pro-inflammatory cytokines like TNF-alpha, and regulates tyrosinase activity to manage pigment distribution.

Key findings
- 01 In vitro testing at 5.0% demonstrated a 45% inhibition of MMP-1, effectively mitigating photoaging-induced collagen loss.
- 02 Studies at 1.0% concentration confirmed significant radical scavenging activity and reduction of lipoxygenase, highlighting its use as a soothing agent.
- 03 Concentrations between 2.0% and 8.0% have shown efficacy in inhibiting melanogenesis and providing antibacterial support against S. aureus.

Dusting Analysis
Because it is a botanically derived patent-linked ingredient, it is often included at negligible levels (below 0.1%) for marketing claims. A minimum of 1.0% is required for antioxidant benefits, while 5.0% is necessary for significant anti-aging collagen protection.
The Formula
