Niacinamide is a form of Vitamin B3 that has been used by dermatologists to treat a plethora of skin conditions. Niacin and its derivative molecules niacinamide and nicotinamide are precursors to two important biochemical molecules: nicotinamide adenine dinucleotide (NAD+/NADH) and nicotinamide adenine dinucleotide phosphate (NADP+). These beneficial molecules help skin cells repair damage and function properly.

By providing your skin the precursor niacinamide you’re providing the essential building block to create NAD+ that helps to allow your skin to fight off and correct free radical damage. Additionally, some evidence points to topical niacinamide helping to increase levels of ceramides (1). Ceramides are lipids that maintain the skin’s health and moisture barrier, helping to alleviate the appearance of fine lines and wrinkles. Topical niacinamide has also been shown to reduce inflammation in the skin, which is why it’s used by dermatologists to treat various skin conditions, such as subtle acne or mild rosacea, etc. When applied to skin niacinamide seems to inhibit oil production which is beneficial to those dealing with acne due to excess sebum build up. Further, a small scale study showed that niacinamide can help to diminish the appearance of fine lines and wrinkles (2). Another study showed niacinamide provides brightening benefits against melasma or facial discolorations (3). Topically, for general skin care, niacinamide appears to work best when combined with other beneficial ingredients.
Paula Begoun, a clean beauty and skin care advocate states on her website (4), “Using niacinamide is as easy as finding great skin care products that contain it along with other beneficial ingredients like antioxidants, skin-restoring agents, and other skin-replenishing ingredients.”
