Science
Mechanism of Action
This extract operates via several distinct mechanisms to enhance dermal well-being. Its antimicrobial efficacy against Gram-positive bacteria, such as Staphylococcus aureus, is achieved by compromising cellular membrane integrity, ultimately leading to cell lysis. The presence of phytochemicals like flavonoids, terpenoids, alkaloids, and phenols confers potent antioxidant properties by effectively neutralizing free radicals. Furthermore, anti-inflammatory actions are observed through the inhibition of superoxide anion generation, elastase release, and the modulation of key signaling pathways (AKT and p38 mitogen-activated protein kinase) within human neutrophils. Traditional use also suggests broader benefits for skin conditions, with some indications of potential antityrosinase activity which could contribute to skin brightening.
