What is Niacin?

Niacin refers to nicotinic acid, a naturally occurring water-soluble B vitamin found in foods like yeast, meat, and grains, and synthesized for cosmetic use. It belongs to the vitamin B3 family and appears as a white crystalline powder. In cosmetics, it features in moisturizers, serums, shampoos, and conditioners targeting skin and hair care. Functionally, it hydrates by drawing moisture to the skin and hair surface, enhances barrier function for better protection, and modifies surface charge to minimize static and friction. This results in softer, more manageable textures. As a multifunctional ingredient, it integrates into emulsions and rinse-off products, aiding even application and residue-free finish without altering pH significantly. Its stability supports broad formulation compatibility.
