Science

Mechanism of Action

Operating as a postbiotic, this ferment filtrate contributes to a balanced and healthy skin microbiome by fostering beneficial bacteria and reinforcing the skin's inherent protection against environmental stressors. It improves skin barrier function, leading to reduced moisture loss and enhanced hydration through its humectant properties. Furthermore, it possesses calming effects to soothe irritation by reducing inflammatory markers like IL-8, and acts as an antioxidant. The fermentation process yields smaller, more bioavailable molecules, which can promote skin regeneration, cell renewal, and maintain optimal skin pH.
