What is NAD+?

If the term NAD+ (short for nicotinamide adenine dinucleotide) sounds familiar, it’s likely because you’ve seen several celebrities receiving IVs infused with the ingredient. Now, the emerging ingredient has entered the skincare arena, with brands including Goop, Aramore, and now Medicube leading the charge. 

According to experts, it’s touted for cellular repair, reducing inflammation, and firming skin, among other anti-aging benefits. Like collagen, NAD+ levels decline as you age, which is why the skincare industry is exploring how it can be replenished to maintain youthful skin.
