Niacinamide
Vitamin B3 — helps with brightening, oil balance, and a stronger skin barrier.
INCI name: Niacinamide
What it is
Niacinamide is a form of vitamin B3 and one of the most researched skincare ingredients. It shows up in everything from $8 drugstore serums to $60 prestige bottles — and the molecule is the same.
What it helps with
- Helps visibly brighten and even out skin tone over time
- Helps regulate the look of excess oil
- Supports the skin barrier (works well alongside ceramides)
- Gentle enough for daily use for most skin types
Good for
- Uneven tone / dullness
- Oily and combination skin
- Barrier-focused routines
- Beginners
Pairs well with
- Hyaluronic acid
- Ceramides
- Zinc (in oil-control formulas)
- Sunscreen (always)
Watch out
Very high percentages (15–20%+) can sting or flush some skin — 4–5% is the well-studied sweet spot for most people. If you are new, start a few times a week.
FAQ
Q. What percentage of niacinamide should I look for?
Around 4–5% is the range most studies use and most skin tolerates well. Higher is not automatically better — 10%+ can irritate sensitive skin without clearly better results.
Q. Can I use niacinamide with vitamin C?
Yes. The old claim that they cancel each other out comes from decades-old, non-realistic lab conditions. Modern formulations combine them safely.
Q. Is niacinamide good for acne-prone skin?
It helps with the look of oil and post-blemish marks, which is why it is popular in acne-prone routines. It is not an acne treatment — for persistent breakouts, see a board-certified dermatologist.

The honest note: ingredients help — they don't treat medical conditions. For persistent skin issues, a board-certified dermatologist beats any product swap.
