Also known as vitamin B3 and nicotinic acid, niacinamide is a very effective skin-restoring ingredient that offers multiple benefits for aging skin. Among these benefits is the ability to visibly improve the appearance of enlarged pores, uneven skin tone, fine lines, dullness, and a weakened skin surface. Niacinamide can also mitigate the damage environmental attack can cause, and is stable in the presence of heat and light.
