Science
Mechanism of Action
This extract utilizes a complex profile of secondary metabolites, including hydroxycinnamic derivatives and oligomeric proanthocyanidins (OPCs), to exert an astringent effect that minimizes pore appearance. It modulates the inflammatory response by downregulating pro-inflammatory cytokines such as TNF-α and IL-8, while its high concentration of polyphenols and vitamin E neutralizes free radicals comparable to the efficacy of Camellia Sinensis (Green Tea).
