Science
Mechanism of Action
This extract operates through multiple pathways to protect and rejuvenate the skin. It notably inhibits Cathepsin G and matrix metalloproteinases (MMPs), key enzymes responsible for collagen degradation and photoaging, offering protection from both UV and infrared rays. As a powerful antioxidant, it neutralizes reactive oxygen species (ROS) and boosts the body's natural antioxidant defenses by increasing ARE activity and HO-1 levels via Nrf2 regulation. Its anti-inflammatory action stems from polyphenols that minimize redness and irritation, and its ability to reduce COX-2 and iNOS protein levels through NF-κB inactivation. Furthermore, it exhibits anti-microbial properties, and assists in preventing hyperpigmentation, leading to brighter, more even-toned skin.
