What is this
Saccharomyces Ferment
Saccharomyces ferment lysate filtrate is obtained by fermenting Saccharomyces yeast, then gently breaking open the cells and filtering the result. The process concentrates amino acids, minerals, vitamins and organic acids, and the filtrate is used in skincare to help revitalise the look of skin, refine texture and support natural moisture.

Questions about saccharomyces ferment
What is saccharomyces ferment?
It is a skincare ingredient born of fermentation. Saccharomyces — the same yeast family behind bread and brewing — is cultured, then its cells are gently broken open (lysed) and filtered, leaving a clear filtrate carrying the amino acids, minerals, vitamins and organic acids the yeast produced.
What does a yeast ferment do for skin?
Its blend of amino acids and minerals helps support the skin's own moisture and smoothness. Used consistently, it softens the look of uneven texture and fine lines, leaving skin with a rested, revitalised, quietly radiant quality.
Are fermented ingredients good for skin?
Fermentation is one of skincare's most enduring ideas — long central to Japanese and Korean beauty. The process breaks larger molecules into smaller, skin-compatible compounds and enriches the ingredient with by-products like amino acids, making ferments gentle and well tolerated.
Is saccharomyces ferment suitable for sensitive skin?
Generally yes. The filtrate is watery-light, free of oil and grain solids, and considered gentle across skin types. In The Nine Aurora formulas it is dosed within mists and serums designed to feel weightless on reactive skin.
