Niacinamide is the physiologically active amide form of vitamin B3. It is a versatile, well-tolerated compound with anti-inflammatory, sebum-regulating, and barrier-strengthening properties. [Draelos 2006]
Mechanism of Action
Inhibits sebocyte lipogenesis and reduces sebum production. Enhances synthesis of ceramides and other intercellular lipids, strengthening the epidermal barrier. Inhibits melanosome transfer to keratinocytes. Suppresses NF-κB pathway activation. [Hakozaki 2002]
