Retinol with niacinamide

Retinol and niacinamide are one of the easier pairs to combine, and many products already contain both. Niacinamide is generally well tolerated and may support the skin barrier, which could make retinol easier to live with. The direct evidence for that is limited, so here is what it does and does not show.

EvidenceSmall and indirect

The short answer

Yes, you can use retinol with niacinamide, in the same routine or at different times of day. Niacinamide is generally well tolerated and may support barrier lipids, and the authors of one study concluded a moisturizer containing niacinamide eased the irritating start of tretinoin. It will not stop retinol irritation on its own, so still build up retinol slowly.

Key takeaways

Retinol and niacinamide have no known conflict and can share a routine.
Evidence that niacinamide makes retinoids easier to tolerate comes mainly from one split-face study of a moisturizer that also contained other ingredients.
Building up retinol slowly matters far more than which supporting ingredient you pair it with.

The basics

Why do retinol and niacinamide pair well?

They do different jobs. Retinol, a vitamin A derivative, speeds skin renewal but often causes dryness and peeling at first. Niacinamide, a form of vitamin B3, is a supporting ingredient: a 2021 review describes it as well tolerated on skin and notes lab work showing it can increase production of ceramides, fats that help hold the skin barrier together.

That makes the logic simple. If retinol stresses the barrier and niacinamide helps support it, using both may be gentler. That is a reasonable idea, not a tested result. The same review also points to studies of combination products containing both that reported improvements in wrinkles.

There is no known chemical reason to keep them apart. For each ingredient on its own, see niacinamide and retinol.

What the research shows

Does niacinamide make retinol less irritating?

Study or source	What it found	Limits
Draelos and colleagues, 2006	Women with sun-damaged skin used a different moisturizer on each side of the face, starting two weeks before 0.025% tretinoin. The authors concluded the moisturizer with niacinamide, panthenol and vitamin E helped skin through the early irritating phase and improved the response.	Tretinoin, not retinol; the moisturizer had three vitamins, so niacinamide’s own effect is unclear; the abstract gives few numbers.
Boo, 2021 review	Topical niacinamide is well tolerated, and lab studies show it can raise ceramide production.	Barrier support is a reasonable reason to pair them, but not proof of less irritation.
Combination product studies	Products containing retinol and niacinamide together reported wrinkle improvement.	Hard to separate each ingredient’s contribution.
Direct trials of retinol plus niacinamide vs retinol alone	We found no strong trial measuring irritation this way.	The tolerability benefit is plausible, not proven.

Step by step

How to use retinol and niacinamide together

Pick whichever option is simplest for you. All are reasonable.

Option 1: niacinamide in the morning
Use a niacinamide serum or moisturizer in the morning and retinol at night. This is the easiest way to start.
Option 2: same evening
Cleanse, apply retinol to dry skin, then a niacinamide serum or moisturizer on top. Our guide to retinol and moisturizer order explains why retinol usually goes on bare skin. If your niacinamide is a watery serum, applying it first is also fine; no study shows one order works better.
Option 3: one combined product
Products containing both are common. Introduce them like any retinol product: a few nights a week at first.
Build up slowly either way
Niacinamide does not make it safe to start retinol nightly. Increase gradually, as in can you use retinol every day.

Worth knowing

When the pair can still cause problems

Main cause

Retinol is still retinol

Most irritation in this pair comes from the retinol. Redness, dryness and peeling are common early on, whatever you pair it with.

Check strength

High-strength niacinamide

The review describes niacinamide as well tolerated, with typical strengths below 5%. Many serums are stronger; if yours stings alongside retinol, a lower strength is worth trying. See is 10% niacinamide too much?

Keep it simple

Too many products

Adding acids or scrubs on top of both raises irritation. Keep the routine short.

Do and avoid

Getting the most from the pair

Do

Start retinol on its own, or with a niacinamide product you already use comfortably.
Moisturize on retinol nights; a moisturizer containing niacinamide is a convenient option.
Wear sunscreen daily while using retinol.
Cut back retinol frequency first if your skin gets irritated.

Avoid

Starting a new retinol and a new niacinamide serum in the same week.
Expecting niacinamide to cancel retinol side effects.
Adding exfoliating acids on retinol nights.
Layering several niacinamide products at once.

Safety and professional-help boundaries

When to check with a professional.

Avoid retinol and other retinoids during pregnancy; the AAD says retinoids should not be used during pregnancy. Ask your clinician about niacinamide and about breastfeeding.
If you use a prescription retinoid, ask the prescriber before adding other products; prescription status varies by country.
Stop and seek advice for swelling, blistering or a rash that spreads.
If you have rosacea or eczema, ask a dermatologist before starting a retinoid.

Frequently asked questions

Short answers to common questions

Can I use retinol and niacinamide together?

Yes. They have no known conflict and can be used in the same routine, at different times of day, or in one combined product.

Should niacinamide go before or after retinol?

Either order is reasonable, and no study shows one is better. A common approach is retinol on dry skin, then a niacinamide serum or moisturizer on top. Niacinamide in the morning and retinol at night also works well.

Does niacinamide reduce retinol irritation?

It may help. In one split-face study, the authors concluded a moisturizer with niacinamide and other vitamins helped people tolerate tretinoin, but it was not a test of niacinamide alone.

Can I use niacinamide and retinol every night?

Niacinamide, yes, if your skin is comfortable. Retinol should still be built up gradually.

Is it OK to use a product that contains both?

Yes. Treat it like any retinol product and start a few nights a week.

Can I add vitamin C to this routine?

Yes, usually in the morning. See our guide on retinol and vitamin C together.
