NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell. This edit offers it in several forms: as a patch with Barrière's NAD+ Youth Repair Patch, as a shot with Happy Aging's NAD+ Longevity Shots, and as face care with THE CORE's NAD+ Face Spray SPF30 Skin Longevity Mist™ and MERME Berlin's Pore & Line Refine Serum.
