In its stable form, cyanocobalamin, also known as vitamin B12 or cobalamin, is a water-soluble vitamin essential for many bodily processes (red blood cell production, DNA synthesis, metabolism of fatty acids and amino acids, and neuron function). It has a chemical structure similar to heme, but with a cobalt atom in place of the central iron atom. Naturally found in liver, fatty fish, eggs, seaweed, and dairy products, it also offers additional benefits in the skincare and haircare sector. Topical vitamin B12 is primarily known and used as a natural colorant with its pink hue to promote a radiant complexion, but it also provides daily benefits to the skin such as increasing collagen production, regulating skin inflammatory responses, neutralizing free radicals, and reducing the proportions of pathogenic bacteria in the skin microbiome.
