When the ingredients of NOX are mixed together, they generate nitric oxide, an essential and important gas that the human body produces naturally to support full body wellness. The older we get, the less nitric oxide the human body produces and this is one of the primary reasons skin shows signs of aging (wrinkles, dryness, spots, etc). Our NOX skin rejuvenation serum delivers the power of this necessary molecule to the face and other areas to which you apply it, allowing users to maintain more youthful skin appearance.
