Science
Mechanism of Action
This extract effectively modulates sebum production, exhibits antiseptic qualities, and purifies the skin, addressing concerns such as acne and blemishes. It possesses anti-inflammatory capabilities by inhibiting the elevation of IL-1β, an inflammatory cytokine, and by acting through both glucocorticoid receptor-dependent and NF-κB pathways. As a rich source of minerals, vitamins, and flavonoids, it functions as a potent antioxidant, protecting skin from damage induced by free radicals, sun exposure, and pollution, thereby contributing to anti-aging benefits. Furthermore, it supports skin brightening by improving the appearance of spots and demonstrates antibacterial and antifungal actions, beneficial for acne-prone skin and scalp conditions like dandruff.
