Niacinamide
Definition
Niacinamide (also known as nicotinamide) is a form of vitamin B3 that has become one of the most versatile and popular active ingredients in skincare. It is water-soluble and works well at concentrations of 2-5%, though some products contain up to 10%. Niacinamide offers a remarkable range of benefits: it strengthens the skin barrier by boosting ceramide production, reduces inflammation and redness, minimizes the appearance of pores, regulates oil production, fades hyperpigmentation by inhibiting melanosome transfer, improves skin texture, and provides antioxidant protection. It is exceptionally well-tolerated by nearly all skin types, including sensitive skin, and plays well with most other active ingredients. Niacinamide is stable, effective at a wide pH range, and can be incorporated into almost any step of a skincare routine. It is found in serums, moisturizers, toners, and sunscreens.
