One benefit of niacinamide is how versatile it is as a skin-care ingredient.
“When used topically, niacinamide can improve skin hydration by preventing evaporation of moisture from the skin into the environment. It’s also a natural anti-inflammatory ingredient, so it’s great for calming irritated skin, but also good for people with sensitive skin,” says Nazarian.
In addition, niacinamide helps prevent premature signs of skin aging, including boosting collagen production to smooth wrinkles and reduce discolorations, says Nazarian. She recommends the ingredient for people with dry, sensitive, aging, or acne-prone skin.
