LACTIC YEASTS

Safety grade: A

Lactic yeasts are beneficial microorganisms that naturally produce lactic acid through fermentation. They are the same type of beneficial bacteria used in yogurt and other fermented foods.

Lactic yeasts are used in cosmetics for their potential to gently exfoliate, brighten skin tone, and support the skin's natural microbiome through their fermentation byproducts.
