What Is Biotin …?
Biotin/folic acid/cyanocobalamin/niacinamide/pantothenic acid/pyridoxine/riboflavin/thiamine/yeast polypeptides is a blend of several B vitamins plus peptides derived from a strain of lab-produced yeast. The B vitamins undergo a chemical reaction with the yeast and proteins (peptides) that is said to boost the stability of the vitamins, allowing them to work better on skin.
This complex conditions and softens skin while also helping to improve the vitality of surface cells. It’s also purported to enhance penetration of ingredients into skin’s uppermost layers while the peptide portion moisturizes skin. All of the B vitamins in this blend play supporting roles in helping skin recover from damage and regain a healthy appearance.
