What Is Pseudozyma Antarctica Ferment Extract?
Pseudozyma Antarctica Ferment Extract comes from the fermentation of a yeast species called Pseudozyma antarctica, originally isolated from Antarctic plant environments. During controlled fermentation this microorganism produces a broth rich in proteins, sugars and lipids that are then filtered and purified to obtain a concentrated extract suitable for skin care. The ingredient entered the beauty scene in the early 2000s when formulators looked for gentle bio-derived actives that could fortify the skin without irritation. Production starts with cultivating the yeast in nutrient media, allowing it to ferment, then separating the solid cells from the liquid and refining the liquid to remove impurities while preserving the active metabolites. You will usually find this extract in lightweight moisturizers, hydrating essences, sheet masks, anti-aging serums and soothing after-sun gels because it pairs well with both water-based and hybrid formulations.

Who Can Use Pseudozyma Antarctica Ferment Extract
This ferment extract is generally well tolerated by all skin types, including dry, normal, combination, oily and sensitive skin, because it hydrates without leaving a greasy film or clogging pores.
