    AnswerYes. You can use them in the same routine.

    The trial most often quoted for this pair did not use retinol or a plain niacinamide serum. Knowing what it did test helps you choose the order, the start and the right 2-in-1 label.

    VerdictFine to use togetherSame routine
    WhyNiacinamide is gentle and well tolerated. In a trial, a niacinamide moisturizer made starting a prescription retinoid easier, and formulas pairing retinol with niacinamide have been tested with good results.
    MorningNiacinamide serum moisturizer SPF 30+
    NightCleanser retinol niacinamide moisturizer
    StartStart retinol every other night; niacinamide can be used daily.
    Both at onceUse them in the same night routine, for example retinol followed by a niacinamide moisturizer. Some products already contain both.

    What each one does

    Retinol

    What retinol does

    A form of vitamin A (a retinoid), used at night for texture and fine lines. It can dry and irritate at first, so most people start every other night.

    Strength tested in most studies: 0.075–0.5%

    Niacinamide

    What niacinamide does

    A form of vitamin B3, studied for acne, oily skin and dark spots. Reviews describe it as extremely well tolerated.

    Usual over-the-counter strength: 2–5%

    Tretinoin and niacinamide: the trial behind the advice

    The study, published in 2006, was a double-blind, split-face trial in women with sun-damaged skin:

    • One side of each face got a moisturizer containing niacinamide, panthenol and vitamin E, twice a day for 10 weeks.
    • Tretinoin 0.025% cream went on the whole face daily from week 2, so the moisturizer had a two-week head start.
    • The authors concluded that strengthening the skin barrier before and during tretinoin eased the early weeks and boosted the result.

    Two limits: the moisturizer held three vitamins, so niacinamide’s own share isn’t known, and the retinoid was tretinoin, about ten times stronger than retinol. If you use tretinoin, MedlinePlus says to stick to non-medicated cosmetics, and a niacinamide moisturizer is a cosmetic. See the tretinoin guide.

    Niacinamide or retinol first?

    Order hasn’t been tested in any trial, so these are expert-consensus rules of thumb:

    • Niacinamide in a moisturizer: retinol goes on first, the moisturizer over it; Cleveland Clinic lists the night sequence as cleanser, retinol, moisturizer.
    • Niacinamide in a watery serum: dermatologists layer from the lightest product to the heaviest, so a watery serum can precede a retinol cream. Either order is reasonable.
    • Easily irritated skin: you can copy the trial’s head start and use the niacinamide product alone for two weeks before adding retinol.

    Retinol and niacinamide serum: reading the label

    2-in-1 serums are common. What to look for:

    • The retinol percent. Labels in the US may leave it off. The AAD’s tip is to pick the lowest concentration available; a 2022 review caps its recommendation for face creams at 0.3%.
    • Which vitamin A form. Retinyl palmitate is much weaker than retinol (0.6% is about half as active as 0.25% retinol), while retinaldehyde ranks above retinol.
    • The niacinamide percent. Cosmetic formulas mainly sit at 4 to 5%, per a 2021 review.

    One catch: a 2-in-1 ties the two together, so you lose the option of daily niacinamide with alternate-night retinol during the first weeks. Two separate products give you that control.

    Questions people ask

    Is 10% niacinamide too strong to use with retinol?

    Not necessarily. In one test, 10% niacinamide caused no stinging or flushing, but skin reactions vary from person to person. If the combination leaves you red, a lower niacinamide strength is one easy thing to change.

    SourceBoo, Antioxidants, 2021 (review of niacinamide)

    Can I add hyaluronic acid as well?

    Yes. All three can share one routine by our mixer’s ratings, and hyaluronic acid can help offset some of retinol’s irritation, according to Cleveland Clinic.

    SourceCleveland Clinic: Retinol (updated June 2022)

    Is niacinamide the same as niacin? Will it make me flush?

    No. DermNet says nicotinamide (another name for niacinamide) does not cause the flushing that its relative nicotinic acid, or niacin, can.

    SourceDermNet: Nicotinamide (updated March 2018)

    What if I’m pregnant?

    Drop the retinol: the AAD advises against retinoids in pregnancy. Your OB-GYN can go over the rest of your routine.

    SourceAmerican Academy of Dermatology: Retinoid or retinol? (updated May 2021)

    How long until I notice a difference?

    Be patient with retinol: Cleveland Clinic says wrinkles usually take several months to change. Niacinamide’s dark-spot effect was measured earlier: in a small study, a 5% moisturizer lightened spots within one to two months of twice-daily use.

    Studies and other sources

    • Draelos et al., Cutis, 2006mdedge.com

      Niacinamide moisturizer eased early tretinoin use in a split-face trial. Paired, double-blind split-face study in women with facial photodamage: a moisturizer with niacinamide, panthenol and tocopheryl acetate used twice daily for 10 weeks, tretinoin 0.025% cream daily from week 2; improving the barrier before and during tretinoin facilitated early retinization and augmented the response.

    • Boo, Antioxidants, 2021mdpi.com

      Niacinamide well tolerated; retinol plus niacinamide combinations tested. Cosmetics mostly use 4–5% nicotinamide; 10% caused no stinging or flushing; skin reactions vary by person; a 5% moisturizer used twice daily reduced hyperpigmentation after 4 or 8 weeks.

    • Adv Ther, 2022: retinoids in topical antiaging, reviewlink.springer.com

      Most retinol studies it covers tested 0.075% to 0.5%; 0.3% is the maximum it gives as recommended for face creams. Retinol is about tenfold less potent than tretinoin; 0.3% is the maximum recommended retinol in face creams; activity ranks retinyl esters << retinol < retinaldehyde < retinoic acid; 0.6% retinyl palmitate is half as active as 0.25% retinol.
