Science
Mechanism of Action
This ingredient, an aqueous solution, delivers beneficial compounds isolated from the Lindera erythrocarpa plant. In in vitro studies, certain isolates like linderaspirone A and dihydropashanone have shown to mitigate inflammation by inhibiting pro-inflammatory mediators such as nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-α, and interleukin-6, alongside modulating pathways like NF-κB and Nrf2/HO-1. These actions also contribute to antioxidant effects by reducing intracellular Reactive Oxygen Species (ROS). Beyond these active properties, it additionally acts as a film-forming, humectant, and skin conditioning agent, potentially offering antimicrobial and skin protecting benefits.
