About GALACTOMYCES/BETULA PLATYPHYLLA JAPONICA JUICE FERMENT FILTRATE
A yeast (Galactomyces) ferment of Japanese white-birch sap. Provides amino acids and antioxidants, but birch-allergic users should beware.
Detailed Analysis
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.
