Niacinamide (nahy-uh-sin-uh-mahyd) is part of the Vitamin B group and is water-soluble. Niacinamide is functionally identical to Niacin; however, it is not as irritating to the skin. Niacinamide has several benefits including anti-inflammatory properties, it increases skin barrier function, decreases skin pigmentation, decreases redness, stimulates collagen, decreases fine lines and wrinkles, and it is non-comedogenic, meaning it won't clog your pores.
Finally we have found an ingredient that is a "hole in one." Because of the anti-inflammatory, skin barrier and anti-redness properties, Niacinamide is commonly used by acne and rosacea sufferers; however, it has also shown superior anti-aging properties and is great for anyone's skin.
