What Is Saccharomyces … Ferment Filtrate?
Saccharomyces-Camellia sinensis leaf-Cladosiphon okamuranus-rice ferment filtrate is a blend of three fermented filtrates (liquids passed through a filter) from green tea, a type of algae, and rice (the Saccharomyces in the name is a type of yeast used in fermentation). It is also known by the trade name Hadasei-3™. It is a proprietary blend used by the TATCHA skin care company.
Though no extensive independent research is available yet on this compound’s effect on skin health, its individual components have a long history of being used to help soothe and soften while providing antioxidant benefits. That’s great, but any claims that this blend is superior to numerous other skin-soothing antioxidants has yet to be proven.
