“Niacinamide is a form of vitamin B3, a multitasking antioxidant that can help soothe, firm and hydrate the skin, reverse the signs of aging (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 hyaluronic acid 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.
