What Is Vitamin B12?
Vitamin B12 is an antioxidant renowned in skin care for its ability to address compromised skin barrier and help relieve signs of sensitivity. While naturally occurring forms of vitamin B12 exist (adenosylcobalamin and methylcobalamin), cyanocobalamin is the synthetic derivative commonly utilized in over-the-counter skin care products due to its superior stability and cost effectiveness.
