Science
Mechanism of Action
Osajin functions primarily as an antioxidant by effectively inhibiting lipid peroxidation, a crucial process in the generation of oxidative stress. Beyond its antioxidative action, it exhibits significant anti-inflammatory effects. Clinical observations from studies involving osajin-containing extracts indicate an increase in skin hydration and a reduction in irritation. As a flavonoid, Osajin may also contribute to anti-aging strategies through potential senolytic and senostatic actions.
