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.

PAULA'S CHOICE:
Also known as vitamin B3 and nicotinic acid, niacinamide is a very effective skin-restoring ingredient that offers multiple benefits for aging and blemish-prone 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 and to some extent help visibly repair damage from UV light and offset other sources of environmental attack, including the negative impact of various types of airborne pollutants. Unlike many beneficial ingredients, niacinamide is stable in the presence of heat and light.
