Start looking for niacinamide on labels: A derivative of vitamin B3, the ingredient has become a skincare star for enhancing radiance and evening tone. “It helps lighten hyperpigmentation by inhibiting the transfer of melanin pigment within the skin,” explains Elizabeth K. Hale, M.D., a clinical associate professor of dermatology at NYU Langone Medical Center and a Prevention advisory board member. It’s also been shown to hydrate, and it won’t cause irritation, making it a great choice for those with sensitive or reactive skin. In skincare products, niacinamide is sometimes combined with ingredients that can irritate, like retinol, to minimize side effects.
