Rice Ferment Filtrate (Sake) – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
The scientific advantage of Rice Ferment Filtrate (Sake) lies in the transformation of dense rice proteins into low-molecular-weight peptides. During the fermentation process (often involving the Aspergillus oryzae fungus), complex nutrients are "pre-digested" into smaller, bio-available units. In skincare terms, this means the amino acids and vitamins can bypass the skin's surface tension more effectively than standard rice water. Specifically, Rice Ferment is rich in Kojic Acid precursors and Ferulic Acid, which provide a "soft-glow" effect by naturally inhibiting surface-level oxidative stress. This makes it a metabolic primer—it doesn’t just sit on the skin; it provides the building blocks the skin needs to maintain a translucent, hydrated, and "glass-like" appearance without the need for aggressive peeling.
