Yeast Ferment Extract

Yeast are microorganisms classified, along with mushrooms and molds, under fungus. Yeast ferment extract was found to help protect the skin from environmental damage and maintain proper hydration by contributing to skin barrier function. In another study, it was also found to increase skin barrier proteins, which may especially be beneficial for certain skin conditions such as eczema that display a decrease in these proteins. Researchers also observed anti-inflammatory effects and protection of skin from damage by another fermented yeast product.
