Science
Mechanism of Action
This root extract harbors key phytochemicals including ecdysteroids (such as 20-hydroxyecdysone), flavonoids, and phenolic acids. Its antioxidant action, primarily attributed to compounds like chlorogenic acid, has been observed to neutralize free radicals. The extract also demonstrates anti-inflammatory effects. A specific component, alpha-amyrin, has shown to enhance human keratinocyte proliferation (HaCaT cells) by approximately 18%, suggesting a role in skin renewal. Furthermore, ecdysteroids are thought to stimulate protein synthesis, a crucial process for maintaining skin structure and repair. It is classified as a skin conditioning agent.
