Science

Mechanism of Action

RHIZOPUS/SACCHAROMYCES/RICE FERMENT EXTRACT FILTRATE delivers comprehensive skincare benefits through several pathways. It significantly boosts skin hydration by increasing endogenous production of hyaluronic acid (HA), natural moisturizing factors (NMFs), and aquaporin 3 (AQP3) channels. The ingredient enhances skin barrier function by promoting the expression of crucial tight junction proteins such as claudin 1 (CLDN1), involucrin (IVL), and zonula occludens-1 (ZO-1), thereby strengthening the skin's natural defenses. As a potent antioxidant, it neutralizes free radicals, mitigating environmental damage and supporting anti-aging efforts by stimulating collagen synthesis and visibly reducing wrinkle depth. Furthermore, it aids in brightening, refines skin texture, promotes cellular renewal, minimizes pore appearance, and regulates sebum production, making it beneficial for acne-prone skin. Its anti-inflammatory properties soothe irritation and reduce redness, while the fermentation process itself may reduce potential irritants, contributing to a gentler profile.
