Niacinamide: everything you need to know about this super skin ingredient

Posted by for Beauty

This super skincare ingredient is proven to treat everything from acne and dehydration to excessive oiliness and pigmentation. Here’s how to make niacinamide work for you.

If we asked you to think of a turbo-powered superstar skin ingredient, vitamin Chyaluronic acid and retinol would probably spring to mind. They’re the hero ingredients frequently lauded as complexion game-changers. But there’s another gentle giant quietly working away in some of our most-loved cleansers, serums and creams.

Forget a jack-of-all-trades, niacinamide is a master-of-everything, tackling fine lines, hyperpigmentation, acne, oily skin, dehydration and uneven skin tone.

To grasp niacinamide’s powers, it helps to understand our skin’s barrier. This is our skin’s gatekeeper and the outermost layer.

When it’s doing its job properly, aggressors such as irritants and pollution are kept away while vital substances like oil and water stay locked in. Skin with a healthy barrier tends to be less sensitive and look radiant, calm, balanced and clear. But this weakens with age, excessive use of acids and actives, over-exfoliation and too much sun. 

    By the time we’re in our 20s, 30s and beyond, it’s common to need a helping hand. This is where niacinamide comes in – strengthening that wall by boosting the production of ceramides (the bricks that make it up).

    It’s is also capable of blitzing pigmentation and is one of the few ingredients that can reduce sebum (oil) production which in turn can help minimise acne.

    “It’s straightforward to use and there’s a niacinamide product for everyone and at any price point,” says dermatologist Dr Sam Bunting.

    Sold? Here’s our guide to your skin’s secret weapon including the best niacinamide products from Paula’s Choice, The Ordinary, Olay and Garden of Wisdom – loved by dermatologists and Stylist’s beauty team alike.  

    What is niacinamide and what is it used for?

    Niacinamide is a form of vitamin B3 that can come from foods such as meat, fish, milk, eggs, green vegetables and grains. But it is easily absorbed by the skin so works brilliantly when applied topically in skincare, too.

    If you’re a fan of featherweight textures, you’re in luck – it doesn’t dissolve in oil so you’re more likely to find it in water-based serums. It features in lots of skincare products, but it’s not always hailed as a star ingredient probably because it does all kinds of jobs rather than one easily-marketed targeted effect. 

    What are the benefits of using niacinamide on skin?

    “There is plenty of research to back up the benefits of using niacinamide in skincare. Primarily, it helps to strengthen our skin’s important barrier. In turn, less vital water is able to escape. This results in a reduction of dehydration and fine lines leaving skin looking plumper, dewier and more youthful,” explains Shabir Daya, pharmacist and co-founder of

    “A stronger barrier also prevents fewer irritants getting in so it’ll work wonders if your skin’s prone to sensitivity, blotchiness and redness. Excessively oily? Niacinamide regulates oil production so your skin will feel more balanced and under control,” Daya adds.

    “Niacinamide is also an anti-inflammatory so it’s useful in unclogging pores and reducing blemishes,” explains Dr Bunting.

    In fact, in an eight-week study, in which acne patients were treated with a 4% niacinamide gel, 82% were considered improved and there were no side effects. In a similar rosacea study, 24 out of 36 patients showed an improvement. And when all the above are eased? You’ll notice smaller pores, too. 

    Can niacinamide be used on all skin types? 

    Absolutely. “Niacinamide is a brilliant all-rounder that the vast majority of people - of all ages and skin types - have no problem tolerating. I rarely see someone who doesn’t get on with it,” comments Dr Bunting.

    Different skin types will benefit from different aspects of niacinamide’s skill set. If you’re oily, you’ll love its oil reduction powers. For the acne-prone, it will help calm those angry red blemishes. If you’re sensitive, it’ll help soothe inflammation and reduce the risk of irritation going forward. 

    Dry skins will benefit from its help with ceramide production and if you’re dehydrated, it’ll strengthen your barrier which in turn will minimise that all important water loss. It’s safe to use when pregnant and breastfeeding, too. 

    How do I apply niacinamide?

    The beauty of niacinamide is that it’ll slot extremely easily into your existing routines. It’s found in everything from cleansers and moisturisers to serums, toners and sunscreens.

    Dr Bunting suggests using a niacinamide serum or moisturiser at night and a sunscreen spiked with it in the morning. It’s safe to use all over (including in the under-eye area) and there are no rules about how to apply it although the same ethos stands as with all skincare. Use your thinnest, most fluid products first and your thicker creams or oils after. Dr Bunting advises applying seven drops of most serums. 

    When and how often should niacinamide be applied?

    As it’s well tolerated by most people, niacinamide can be used twice a day everyday. It works at any time of the year although it comes in particularly handy in winter during cold, dry weather and frequent use of central heating.

    “It’s also a very useful tool if you’re about to start using skincare containing any new powerful active ingredients as it’ll make you less prone to irritation,” explains Dr Bunting. “This is particularly helpful with retinol products that have a tendency to be irritating. Retinol also impacts your production of ceramides so niacinamide will help build those up again. You’ll notice your skin’s less dry from the retinol as a result,” 

    Use it in the run-up before starting your retinol treatment and alongside it, too. Try using it directly before the retinol or use your retinol product at night and niacinamide during the day. 

    How long does it take for niacinamide to work?

    You’ll notice some effects immediately although most of the studies on niacinamide showed results after 8-12 weeks. Look for products containing 5% niacinamide. That’s the percentage that’s been proven to visibly make a difference without causing any irritation. Products with higher concentrations do exist, although you might find they’re best targeted onto individual areas, instead, as they can be slightly more irritating.

    Can niacinamide be used in combination with other ingredients?

    Yes. There’s a misconception that niacinamide can’t be mixed with vitamin C but it’s not true - they won’t render each other less effective and actually form a powerhouse combo. “Together, they’ll leave skin looking more radiant, smoother, more even and noticeably younger-looking,” says Paula.

    It’s also compatible with peptides, alpha hydroxy acids (AHAs) like glycolic acid, beta hydroxy acids (BHAs) like salicylic acid and antioxidants.  

    Does niacinamide lighten skin?

    Don’t worry, niacinamide won’t bleach skin however it is able to fade dark spots caused by age, spots or the sun resulting in a more luminous, even skin tone.

    “Niacinamide has a powerful hyperpigmentation-blitzing effect. It reduces the transfer of pigment called melanin from the pigment cells (melanocytes) to the skin cells. For that reason, it’s also really helpful if you’re prone to post-inflammatory marks left behind after blemishes,” comments Dr Bunting.

    “It’s so effective it’s even used to reduce melasma - a condition with marked facial hyperpigmentation that’s notoriously difficult to treat,” adds Daya.
