Science
Mechanism of Action
Functions as a multifaceted antioxidant system by leveraging polyphenols, flavonoids (particularly quercetin derivatives), and anthocyanins to neutralize reactive oxygen species and prevent lipid peroxidation. The natural tannins provide mild astringent effects that help refine skin texture, while potential anti-alpha-glucosidase activity may support cellular metabolic processes beneficial for overall skin health.
