Niacinamide Malate

Niacinamide malate is niacinamide (vitamin B3) bonded with malic acid. This combination is intended to improve the stability and delivery of niacinamide in skincare formulations. Niacinamide itself is a water-soluble vitamin that plays a role in skin barrier function and cellular energy production.The malate component may offer additional benefits as a gentle exfoliating acid, though niacinamide malate is typically used as a skin conditioning agent rather than as an active exfoliant. The ingredient functions primarily to condition and support skin health.

Niacinamide works by supporting the skin's natural processes. It aids in the synthesis of ceramides and fatty acids that form part of the skin barrier, and plays a role in cellular energy metabolism. This helps skin maintain its structural integrity and protective function.By combining niacinamide with malic acid, the formulation may enhance penetration or stability compared to standard niacinamide, though evidence on the specific advantages of the malate form over other niacinamide derivatives is limited.

Niacinamide malate is typically used in serums, moisturisers and essences. It can be layered with other actives and is generally compatible with most skincare routines. As with any new ingredient, introduce it gradually if you have sensitive skin and observe how your skin responds over 2–4 weeks.

Niacinamide is generally well-tolerated across all skin types. Rare sensitivity or flushing can occur, particularly at higher concentrations. Malic acid is a gentle AHA, so avoid combining with stronger exfoliants if using niacinamide malate at meaningful concentrations.
