Nicotinamide adenine dinucleotide (NAD) is a vital molecule found in all living cells. It is associated with skin cell energy processes that may contribute to a more vibrant, youthful-looking complexion. Products formulated with NAD may visibly improve skin tone and texture, helping skin look smoother and more youthful.

Research has explored the use of NAD in cosmetics, sourced from botanicals like dill and sunflower or synthesized — with studies examining its effects on skin samples across a range of formulations.
