FAQ’s
What is niacinamide?
A form of vitamin B3 commonly found in meat, fish, milk, eggs, and green vegetables, niacinamide is an essential vitamin that helps with cell health and energy metabolism. Also a popular skincare ingredient, its anti-inflammatory qualities mean it’s great for helping with acne, eczema, and rosacea — but it’s also just generally great for maintaining healthy-looking skin as a whole.
What are the benefits of niacinamide in skincare?
“Niacinamide is a form of vitamin B3, a multitasking antioxidant that can help soothe, firm and hydrate the skin, reverse the signs of ageing (including fine lines and wrinkles), lighten dark spots and redness as well as reduce inflammation and stimulate collagen production — which may benefit conditions like acne and rosacea,” shares Deanne Robinson, MD, a board-certified dermatologist in Westport, Connecticut.
Not to mention, niacinamide is known to pair well with other active ingredients. “Niacinamide is a soothing ingredient, so it can help make an exfoliating ingredient or product more tolerable to sensitive skin, allowing you to use it more frequently and see the benefits of it,” she says. “Because of these properties, it pairs well with retinols and alpha hydroxy acids, or AHAs.”
Otherwise, niacinamide can also enhance the hydrating benefits of humectants — think the best hyaluronic acid serums and glycerin — so it’s a winner in moisturisers, too. “It works by preventing evaporation of moisture from the skin into the environment,” Dr. Robinson explains. In other words, it helps support our delicate moisture barriers too.
Heads up: to maximise the benefits of niacinamide, sunscreen is essential, so make sure you follow up your serum with a product that has at least SPF 30, which is the minimum amount recommended by the American Academy of Dermatology. Simply apply a few drops to the palm of your hand morning and evening, apply after cleansing and toning, and follow with a moisturiser and your trusty face SPF. Bottom line: There’s no reason not to slot this powerhouse topical ingredient into your skincare routine.
What is the best percentage of niacinamide?
“Clinical studies suggest that niacinamide is effective at concentrations between 2-5%, with proven benefits including improved barrier function, reduced transepidermal water loss, and control of sebum production,” explains Dr Nora Jaafar — cosmetic and medical dermatology doctor at Rejuvenation Clinic. “Concentrations of 10% or more can also be really beneficial, but they come with an increased risk of irritation — particularly in individuals with sensitive skin.”
Can all skin types use niacinamide?
Niacinamide is well-tolerated across all skin types — but some will benefit from using it more than others. “It’s particularly beneficial for those with acne-prone or oily skin, as it helps regulate sebaceous gland activity, and reduce inflammatory lesions,” Dr Nora explains.
Can you use niacinamide with vitamin C?
While outdated research sometimes suggests the opposite, we can assure you that you’re totally fine to use modern formulations of niacainamide and vitamin C together. “Niacinamide has anti-inflammatory and skin barrier-enhancing properties — while vitamin C (ascorbic acid) functions as a potent antioxidant and collagen-stimulating agent,” Dr Nora explains. “When used together, they can provide complementary benefits for brightening and photoprotection.”
Can I use niacinamide every day?
In short — yes. “Studies show that consistent use — both morning and evening — can enhance barrier function, regulate oils, and reduce oxidative stress,” Dr Nora adds.
What does “built-in interest” actually look like? It can be interesting construction at the neckline (so you get the dressed-up feeling without a necklace sitting hot against your skin), decorative detail woven into the garment itself, pattern or print, colour (not just neutrals, actually wear what works for you), or fabric texture. Eyelet fabric is a perfect example; those little cutouts do double duty: they add visual interest, and they breathe. Anything with an interesting weave, texture, or pattern built into the cloth itself can make a plain silhouette feel considered and intentional.
The question to ask yourself is: can you find a dress that suits your personality AND has that built-in detail we talked about? Because if you can, you have an outfit that requires nothing else. That’s the goal.
And here’s one I’ve been using a lot this summer: brooches. Brooches are genuinely back (they never really went away, but they’re having a moment), and pinning a brooch at the neckline gives you that elevated, Classic-style feeling without anything hanging around your neck in the heat. It’s a small shift with a surprisingly big payoff.
