Niacinamide, also known as vitamin B3, has a variety of skin-care benefits, in addition to being effective at brightening your skin tone. "It has numerous skin-protecting and moisturising benefits that may help improve [the look of] enlarged pores, uneven skin tone, hyperpigmentation, fine lines, wrinkles, and dullness," said Dr. Nussbaum.
Thanks to this long list of benefits, niacinamide makes a great addition to any anti-ageing skin-care routine, especially if you want to calm inflammation and support collagen production, according to Dr. Imahiyerobo-Ip.
