Why Galactomyces Is the Secret to Glass Skin
Galactomyces ferment filtrate is a yeast-derived ingredient created through the fermentation of sake (rice wine) yeast. Japanese brewery workers were historically known for having remarkably soft, youthful hands despite their age — a phenomenon attributed to constant contact with fermented yeast. Korean skincare took this observation and turned it into one of the most effective brightening ingredients in modern skincare.
Galactomyces filtrate is rich in amino acids, vitamins, minerals, and organic acids that work together to improve skin clarity and texture. It enhances the skin's natural moisture factor, accelerates cell turnover for smoother texture, and inhibits melanin production for a brighter, more even complexion. This combination of benefits is what makes it central to the coveted "glass skin" look.
Fermented Skincare: Why Fermentation Matters
Fermentation breaks down molecules into smaller, more bioavailable forms that penetrate the skin more effectively. The fermentation process also produces beneficial byproducts — like amino acids, peptides, and antioxidants — that the original ingredient does not contain. This is why galactomyces ferment filtrate is more effective than raw yeast extract: the fermentation process creates a nutrient-dense concentrate optimized for skin absorption.
