Niacinamide Is Skincare's Low-Key Multitasker

A well-studied ingredient that plays nicely with everything.

Skincare aisles are full of hype ingredients. Niacinamide is one of the quieter ones that actually delivers.

A do-a-bit-of-everything active

Niacinamide (a form of vitamin B3) has solid evidence for calming redness, supporting the skin barrier, softening the look of pores, and helping regulate oil. It's gentle, and unlike stronger actives, it rarely irritates — even sensitive skin usually tolerates it well.

Easy to add

It layers comfortably with most other ingredients, including moisturizers and sunscreen, so you don't have to build a complicated routine around it. Concentrations around 5% capture most of the benefit.

The move

If you want one low-risk addition to a simple routine, a niacinamide serum or a moisturizer that includes it is a safe bet. Give it a few weeks — the results are gradual, not overnight.
