Yeast Extract (Vitamin B)
Yeast Extract Derived from yeast (Saccharomyces cerevisiae), this extract comprised of a complex mixture of proteins, sugars and amino acids acts as an excellent humectant and may be instrumental in enhancing the rate of cell turnover in the skin. Because its properties are analogous to soluble collagen, it is often referred to as pseudocollagen. Recent studies indicate that extracts of yeast also aid in reducing hyperpigmentation by blocking melanin biosynthesis.
