    Nicotinamide Adenine Dinucleotide, also known as the physiological form of Vitamin B3, NAD is involved in DNA repair and is necessary for metabolism in the living cell. As an essential vitamin, when applied topically NAD improves skin's surface structure, smooths the look of wrinkles and helps to inhibit damage caused by ultraviolet rays. NAD  will help reset the appearance of age by smoothing the appearance of wrinkles, also brightening, tightening and hydrating the look of your complexion.

    NAD cas 53-84-9, known more formally as beta-nicotinamide adenine dinucleotide hydrate, is a signaling molecule as well as a cofactor or substrate for many enzymes.It acts as an oxidizing agent, accepting electrons from other molecules while being converted to its reduced form, NADH. NAD+ is also essential for the activity of several enzymes, including poly(ADP)-ribose polymerases and cADP-ribose synthases. For example, it is used by some sirtuins to mediate protein deacetylation, producing O-acetyl-ADP-ribose and nicotinamide as well as the deacetylated protein.
