Probiotics and Postbiotics are trending in skincare. One skincare ingredient that is gaining traction is Saccharomyces Ferment. Find out how this ingredient can level up your skincare routine, and some of our favorite products containing this yeast ferment.
What is Saccharomyces Ferment
Saccharomyces Ferment is a probiotic yeast obtained by fermentation. It is considered a postbiotic. 
A moisturizing, skin- soothing, nutrient rich yeast ferment that stimulates cell renewal with amino acids and peptides. It is well tolerated even by sensitive skin types.
Why is Fermentation Useful?
Fermentation increases nutrient density like a skincare ingredient “power level up”.
In Saccharomyces Ferment, it adds nutrients to a formulation as it produces amino acids and peptides. Amino acids and peptides can be easily absorbed by the skin to promote collagen synthesis and nourish our skin cells.
The beta-glucan in Saccharomyces Ferment enhances its’ ability to provide a buffer for potent actives within a formulation.
It increases oxygen flow to skin cells. The better the oxygen flow and consumption, the better vital skin components such as collagen and elastin are maintained.
Saccharomyces lysate extract is believed to neutralize toxins such as trace heavy metals and pesticides.
