Touted for its barrier-loving and brightening powers, niacinamide is a staple in many of our skincare routines. But like with all hard-working ingredients, it's important to know how often you can actually apply them - for the best efficacy and minimal irritation.
Like the best hyaluronic acid serums, niacinamide is a very popular ingredient for boosting hydration and moisture retention, but it's also known to tackle hyperpigmentation and repair the skin's barrier. It can be found in many forms, from cleansers to targeted serums and while we know niacinamide can be good for acne, it's not always clear how often we can slather our faces in it.
