Science
Mechanism of Action
This extract functions as a potent antioxidant, neutralizing free radicals and mitigating oxidative stress, including damage induced by blue light exposure. This protective action helps preserve skin protein integrity, thereby minimizing the appearance of fine lines, wrinkles, and hyperpigmentation. Its anti-inflammatory capabilities are robust, interrupting key pathways that trigger inflammation. Studies on the root extract demonstrate its ability to inhibit mast cell infiltration and reduce inflammatory cytokine secretion (TNF-α, IL-6, IL-8, IL-31) through modulation of NF-κB, Akt, ERK1/2, p38 MAPK pathways, and upregulation of HO-1 via NRF2 nuclear translocation. Furthermore, it acts as a humectant and skin conditioning agent, drawing moisture into the skin and supporting its overall healthy state. Preliminary data also suggests potential antimicrobial properties, offering defense against certain skin infections like acne, and contributing to a brighter complexion.
