Science
Mechanism of Action
This extract, abundant in polyphenols, anthocyanins, and flavonoids, functions as a powerful antioxidant by scavenging reactive oxygen species (ROS) and mitigating free radical damage. Its anti-inflammatory action involves suppressing NF-κB protein expression and reducing inflammatory cytokine secretion, thereby calming irritation. As a natural humectant, it enhances skin hydration and moisture retention, while its fatty acid content nourishes and inhibits hyaluronidase, preventing hyaluronic acid degradation. The presence of vitamin C contributes to skin brightening by inhibiting melanin production, promoting a more even tone. Furthermore, it supports anti-aging by inhibiting collagenase (MMP-1) and elastase, stimulating cellular proliferation, and boosting procollagen type I synthesis via TGF-β/Smad signaling. It also offers mild antimicrobial benefits, making it suitable for blemish-prone skin, promotes regeneration, and can bolster the skin's resistance to oxidative damage from UV exposure.
