Science
Mechanism of Action
This ingredient functions primarily as a physical abrasive, gently sloughing off dead skin cells and impurities to facilitate epidermal regeneration and achieve a smoother skin texture. Additionally, it contributes antioxidant and anti-inflammatory properties due to its rich composition of bioactive compounds such as polyphenols, flavonoids, tannins, fatty acids, and vitamin E.
