What is niacinamide?

Niacinamide (vitamin B3) is one of the most versatile and well-researched ingredients in skincare. It works on multiple levels simultaneously: it strengthens the skin’s moisture barrier by stimulating ceramide production, visibly minimises the appearance of enlarged pores, regulates excess sebum (making it useful for both oily and combination skin), and helps fade the look of uneven tone and post-blemish discolouration over time. Unlike more aggressive actives such as retinol or alpha hydroxy acids, niacinamide is non-irritating and works gently and steadily — making it suitable for daily use by all skin types, including sensitive and redness-prone skin. It also plays well with almost every other skincare ingredient, including retinol, peptides, and vitamin C.
