Overview
A yeast ferment filtrate, famous from sake brewing, used in essences for hydration and a smoother-looking surface.
What it is
Galactomyces ferment filtrate originates from the observation that sake brewers' hands appeared unusually smooth. The filtrate is rich in amino acids, minerals, and organic acids produced during fermentation.
It anchors several iconic 'first essence' products in Japanese and Korean skincare.
How it works
- Fermentation produces small molecules — amino acids, peptides, organic acids — that can hydrate and condition.
- Some studies suggest antioxidant activity and support for barrier-related markers; evidence is modest.
Potential benefits
- Hydration and smoother-looking texture
- Brighter appearance with consistent use, per manufacturer studies
Potential benefits describe what research and use suggest may occur for many people — not guaranteed outcomes. Individual responses vary.
Who might consider it
