Yes, you can use retinol and niacinamide together, and for most people it's a good pairing. Niacinamide doesn't cancel retinol out. It helps your skin barrier hold on to water, so the dry, flaky, red-looking phase that comes with starting retinol tends to be milder. Apply the thinner product first, and start retinol slowly.
Does niacinamide neutralise retinol?
No. The "don't mix them" idea is mostly borrowed from an older worry about niacinamide and vitamin C, and even that one doesn't hold up well in modern formulas. Retinol and niacinamide don't react with each other in a way that makes either one stop working.
They also do different jobs. Retinol speeds up the rate your surface cells turn over, which is why skin looks smoother and more even after a couple of months. Niacinamide (vitamin B3) supports the lipids in your outer layer, so skin loses less water.
One pushes change, the other keeps the wall steady while that change happens. If you want the full picture on what niacinamide sits well with, our guide to layering niacinamide covers the other common pairs.
What happens if you use niacinamide with retinol?
The best evidence we have is small but consistent. In a 10-week study of 25 people using a night cream with 0.5% retinol and 4.4% niacinamide in the same formula, fine lines, radiance and smoothness looked better from week 2. Mild flaking and redness showed up early, and by week 10 nobody reported stinging, itching, dryness or tingling.
An older split-face study tested the barrier idea directly. People used a moisturiser with niacinamide, panthenol and vitamin E on one side of the face and a plain moisturiser on the other, starting two weeks before a retinoid. The side that got the barrier-supporting moisturiser handled the early weeks better. Neither study is huge, so read this as "helps the adjustment" rather than "removes it."
If you've already started retinol and your skin is peeling, that's normal in the first few weeks. Here's why skin peels after starting retinol and what to do about it.
Do you use retinol before or after niacinamide?
Thinnest to thickest is the simple rule. A watery niacinamide serum goes on first, then retinol, then moisturiser. Let each layer sink in for a minute or so; you don't need to wait 20 minutes between them.
A few setups that work:
- Serum then retinol: niacinamide serum, retinol, moisturiser. The standard order.
- Sandwich: moisturiser, retinol, moisturiser. Good if your skin is dry or you're in your first month.
- Alternate nights: retinol on two or three nights a week, a niacinamide cream on the others.
- One product: a retinol cream that already contains niacinamide saves a step.
If you go the alternate-nights route, a niacinamide-led night cream is an easy fit for the off nights. Just know that products with only a trace of vitamin A don't give you retinol results, whatever the name says.
How to start retinol with niacinamide
Go slower than you think you need to. Use a pea-sized amount of retinol for the whole face, two or three nights a week for the first two to four weeks. Keep niacinamide daily if your skin likes it, morning or night.
If your skin still feels tight or looks flaky, add a barrier layer on top. Ceramides pair well here, and there's a step-by-step on layering ceramide with retinol. Hyaluronic acid under retinol helps too; see how to use hyaluronic acid with retinol. Once a few weeks pass without much flaking, add a night.
What should you keep off your retinol nights?
Strong exfoliating acids and benzoyl peroxide. Putting a high-strength AHA or BHA on the same night as retinol is the most common way people end up raw and red-looking. Use them on different evenings. Niacinamide has its own short list of things to watch, which we cover in what not to mix with niacinamide.

Sunscreen matters more once you're on retinol
Retinol makes fresh surface cells come through faster, and fresh skin burns more easily. In Australia that's not a small thing. Cancer Council Australia recommends sun protection whenever the UV index is 3 or above, with an SPF50 or SPF50+ broad-spectrum sunscreen, reapplied every two hours.
For most of the country that's a daily habit for much of the year. Niacinamide in the morning sits happily under sunscreen, so it doesn't have to live only in your night routine.
Keep retinol at night, niacinamide wherever it fits, and give your skin a month before you judge the result.

FAQ
What happens if I use niacinamide with retinol?
Usually nothing bad, and often something good. Niacinamide doesn't switch retinol off. In studies where the two were used together, people still got the smoother, brighter look from retinol, and the flaky, red phase in the first weeks tended to settle as skin got used to it.
Do you use retinol before or after niacinamide?
Apply the thinner product first. For most routines that means a niacinamide serum on clean, dry skin, then retinol, then moisturiser. If your retinol is a cream, it can go on after the serum and before or instead of your moisturiser.
What shouldn't you mix with retinol?
Strong exfoliating acids (high-strength AHA or BHA) and benzoyl peroxide on the same night are the usual trouble. Keep them on alternate nights and give retinol its own evenings, especially in the first month.
What do Koreans use instead of retinol?
Many K-beauty routines reach for gentler options first: bakuchiol, adenosine, peptides, or low-strength retinol derivatives paired with niacinamide. They're easier to use every night, though a proper retinol is still the stronger choice for visible texture change.
