Science

Mechanism of Action

This ingredient is rich in anthocyanins, ellagitannins, polyphenols, and vitamins C and E, providing robust antioxidant defense by effectively neutralizing free radicals from environmental factors like UV exposure and pollution. Its anti-inflammatory action helps soothe irritation and can mitigate UVB-induced inflammation by modulating pathways such as NF-κB and COX-2. Skin brightening effects are achieved through the inhibition of tyrosinase activity, which reduces dark spots and enhances overall radiance. Furthermore, it possesses anti-aging properties by inhibiting elastase and collagenase while stimulating type 1 pro-collagen synthesis, thereby reducing the appearance of fine lines and wrinkles. It also contributes to skin hydration and barrier function by potentially influencing genes responsible for hydration and stimulating ceramide production. Astringent qualities from tannins may assist in mild exfoliation, and it also exhibits antimicrobial benefits.
