What Is Saccharomyces Lysate?
Saccharomyces lysate is a probiotic yeast obtained by fermentation. Its by-products, known as postbiotics, can help normalize skin’s microbiome by curbing the proliferation of microorganisms on skin’s surface that can trigger impairment.
This lysate can also be a good source of other beneficial ingredients for skin, such as amino acids, various vitamins and minerals (the variance is due to type and method of fermentation), and elements such as nitrogen and carbon, all of which contribute to healthier-looking skin. Use levels of Saccharomyces lysate in cosmetics are typically between 1–5%; however, blends with this ingredient may contain lesser amounts since its role in this case is more about supporting the other ingredients.
