Science
Mechanism of Action
This extract operates by delivering a complex array of antioxidants, including gallic acid, tannic acid, flavonoids, alkaloids, glycosides, and sterols, to neutralize damaging free radicals and reactive oxygen species (ROS). It actively reduces UVB-induced apoptotic cytotoxicity in human epidermal keratinocytes by modulating ROS-eliminating pathways, decreasing mitochondrial dysfunction, and inhibiting caspase-3 activity. Concurrently, it stimulates collagen and elastin production, reinforcing skin structure, and may aid in reducing hyperpigmentation by lowering bilirubin levels, thus enhancing skin elasticity and reducing the appearance of dark spots and sallowness.
