Science

Mechanism of Action

The efficacy of Rubus Occidentalis Fruit Extract lies in its high concentration of bioactive compounds, particularly anthocyanins and ellagitannins. Specific components such as cyanidin-3-rutinoside (C3R) and cyanidin-3-glucoside (C3G) exert anti-inflammatory effects by down-regulating NF-κB expression and inhibiting I-κB degradation, pathways central to inflammation. Beyond direct anti-inflammatory action, it bolsters the skin's natural defenses against oxidative stress by enhancing protective enzymes. This action is linked to improved synthesis of crucial structural proteins like collagen, elastin, and fibronectin, essential for maintaining skin integrity. Furthermore, it supports tissue repair through increased angiogenesis and wound contraction, while offering potential antimicrobial benefits and protective effects against UV radiation-induced damage.
