Niacinamide, also known as vitamin B3, is a powerhouse ingredient in K-Beauty, valued for its ability to brighten the complexion while strengthening the skin barrier. It helps to even out skin tone, minimise the appearance of enlarged pores, regulate excess oil production, and reduce the look of fine lines over time. Gentle enough for most skin types, niacinamide is commonly found in serums, essences, and moisturisers, where it works alongside hydrating ingredients to promote the clear, radiant, and healthy-looking skin that K-Beauty is known for.
