Saccharomyces/Zinc Ferment

What Saccharomyces/Zinc Ferment is & what it does

Saccharomyces/Xylinum/Black Tea Ferment is a fermentation product made by culturing yeast and Xylinum bacteria with black tea, similar to a kombucha ferment. In skincare it is used as a skin-conditioning ingredient that supplies a mix of organic acids, sugars, and metabolites from the fermentation process. Ferment ingredients like this are often included for their hydrating and antioxidant-associated character.

What does Saccharomyces/Zinc Ferment do in skincare?

Saccharomyces/Zinc Ferment is made by fermenting yeast (Saccharomyces) in the presence of zinc, creating a bioavailable, zinc-enriched ferment. In skincare it is used as a conditioning ingredient and as a way to deliver zinc, which is often associated with skin-soothing and balancing claims. It is a supporting ingredient rather than a sunscreen filter.

Is Saccharomyces/Zinc Ferment natural or synthetic?

It is produced by a natural fermentation process using yeast, so it is generally regarded as a naturally derived ingredient. The zinc is incorporated during fermentation rather than added as a standalone synthetic compound at the end.

Is Saccharomyces/Zinc Ferment vegan?

Yeast ferments like this do not require animal-derived materials, so the ingredient is typically suitable for vegan formulas. Confirming with the brand is still the best way to be sure about the finished product.
