Science
Mechanism of Action
This root extract operates through multiple pathways to support skin health. Its primary mechanism involves powerful antioxidant and anti-inflammatory actions, which mitigate cellular damage and soothe irritation. Bioactive compounds, including coumarins and chromones, are believed to modulate immune responses by significantly reducing nitric oxide production in activated immune cells, thereby calming inflammatory processes. It also exhibits antimicrobial characteristics and functions as a skin conditioning agent.
