Niacinamide (Nicotinamide) is a nicotinic acid amide. A powerful antioxidant. It acts as an inhibitor of melanosome transfer from melanocytes to keratinocytes, and leads to improved facial hyperpigmentation. In fibroblast culture, it increases the production of collagen, which consequently leads to an increase in skin elasticity and a reduction in fine lines. It plays a role in the biosynthesis of ceramides and other SC lipids, resulting in a reduction in transepidermal water loss (TEWL).
