Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A multi-mineral yeast ferment used as a skin conditioning ingredient. It supplies trace elements bound to yeast metabolites, but germanium inclusion gives it a weaker safety dossier than simpler ferments.

Skin benefits

  • Delivers trace minerals via yeast fermentation
  • Provides amino acids and beta-glucans for skin conditioning
  • Yeast ferment can support antioxidant defence
  • Bioavailable mineral chelation

Known concerns

  • Germanium content has limited cosmetic safety data
  • Mineral concentration not standardised across suppliers
  • Possible sensitisation in yeast-allergic individuals
  • Heavy metal trace impurities require monitoring
