Science
Mechanism of Action
This extract operates through a complex antioxidant network, neutralizing free radicals and inhibiting pro-inflammatory cytokines to mitigate oxidative stress. It further supports skin regeneration by stimulating the proliferation of fibroblasts and keratinocytes, while its polyphenol and amino acid content helps inhibit tyrosinase activity and protect collagen fibers from degradation.
