Niacinamide is one of those ingredients that seems to be in everything now — serums, moisturizers, toners — and unlike a lot of trends, it earns its spot. It is gentle, well-tolerated, and genuinely useful for a wide range of skin concerns. Here is what niacinamide actually does and how to use it, from a licensed esthetician.
What is niacinamide?
Niacinamide is a form of vitamin B3. It is a water-soluble ingredient that supports your skin barrier and regulates several processes at once, which is why it helps with so many different concerns without the irritation that stronger actives can cause.
The benefits
- Regulates oil — helps balance sebum, so it is great for oily and combination skin.
- Minimizes the look of pores — by keeping oil in check and supporting the skin around the pore.
- Calms redness and inflammation — soothing for sensitive, reactive, or rosacea-prone skin.
- Fades pigmentation — helps interrupt the transfer of pigment, gradually evening out tone and dark spots.
- Strengthens the skin barrier — boosts ceramides so skin holds moisture and is more resilient.
- Plays well with others — one of the few actives that layers happily with almost everything.
How to use it
Niacinamide is beginner-friendly. A 5% serum is plenty for most people (higher percentages can cause flushing in some and are not necessary). Apply it after cleansing and before moisturizer, and it can be used morning, night, or both. Because it is so gentle, it fits almost any routine.
Can you use niacinamide with retinol or vitamin C?
Yes to both. Niacinamide actually pairs beautifully with retinol — it helps buffer some of retinol’s irritation while you build tolerance. And despite an old myth, niacinamide and vitamin C can be used together safely; if you are sensitive, you can simply use vitamin C in the morning and niacinamide at night. This is exactly the kind of routine-building we help clients sort out so their products work together, not against each other.
