Niacinamide: The Multitasker Worth Knowing
Why this form of vitamin B3 is one of the most versatile and well-tolerated ingredients in skincare — what it does, what it does not do, and how to use it.
is vitamin B3 in a form your skin can use directly. Unlike many actives, it addresses several concerns at once without being harsh — which is why you see it in almost every skin-type category.
What niacinamide actually does
- Strengthens the by increasing ceramide and fatty-acid production.
- Reduces oil production — shown in studies at 2–4% to decrease sebum output.
- Fades hyperpigmentation by interrupting the transfer of melanin to skin cells.
- Calms redness and visible inflammation.
- Pairs well with almost everything — retinoids, acids, vitamin C — making it a versatile supporting ingredient.

Good for
- Oily and acne-prone skin

Concentrations and what to expect
Studies show effect at 2–5%. Most serums are in the 5–10% range. Higher is not always better — concentrations above 10% are more likely to cause temporary flushing in sensitive skin. The sweet spot for most people is 5%.
Myth
Niacinamide and vitamin C cancel each other out.
