Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A yeast (Galactomyces) ferment of Japanese white-birch sap. Provides amino acids and antioxidants, but birch-allergic users should beware.
This ingredient is the filtrate of Galactomyces yeast fermentation using the juice (sap) of Japanese white birch (Betula platyphylla japonica) as the substrate. It provides a mix of amino acids, organic acids, B-vitamins, polysaccharides, and birch-derived polyphenols and minerals. Galactomyces filtrates are best known from K-beauty essences with a moderate evidence base for skin smoothing and barrier-conditioning effects. The birch component carries allergen risk for users sensitized to birch pollen (Bet v 1 cross-reactivity). No CIR-specific review; safety is generally inferred from related ferments. Limited standardization between suppliers.
