Science
Mechanism of Action
This extract operates through a sophisticated blend of phytochemicals. Its high antioxidant capacity, attributed to compounds like quercetin, lutein, α-tocopherol (vitamin E), and anthocyanins (reported to be three times more potent than blueberries), effectively neutralizes environmental stressors, offering soothing and anti-aging effects. The presence of polygodial provides potent anti-inflammatory, anti-allergic, and antimicrobial benefits. Additionally, rutin strengthens capillaries, which may contribute to reducing dark undereye circles. For dermal concerns such as stretch marks, it supports skin restoration by increasing pro-collagen I and elastin concentrations and promoting TGF-β production.
