Science
Mechanism of Action
This extract exerts significant antioxidant effects, attributed to its rich content of phenolic compounds and flavonoids, which neutralize free radicals. Beyond its antioxidant capacity, it functions as a skin conditioning agent, enhancing skin texture and appearance. While primarily noted for hair growth stimulation via the Wnt/b-catenin pathway and VEGF production, its direct mechanisms for skin regeneration and anti-aging in skincare context are largely linked to its protective antioxidant profile.
