Niacinamide

Niacinamide is a water-soluble form of vitamin B3 (nicotinamide) that is synthetically manufactured for cosmetic use. It works through multiple mechanisms: suppressing melanin transfer to skin cells to reduce hyperpigmentation, stimulating ceramide and fatty acid synthesis to strengthen the skin barrier, regulating sebum production, and exerting anti-inflammatory effects. It is one of the most well-researched and versatile active ingredients in skincare.
