What Is Yeast Extract?
Yeast extract may sound like a simple ingredient but is in fact a complex source of numerous beneficial compounds for skin, including antioxidant compounds known as flavonoids, B vitamins, minerals (magnesium zinc), fatty acids, plus protein and lipid enzymes. Glycolipids known as glucosylceramides can be derived from yeast and have a role in improving skin’s barrier.
