NAD+: The Coenzyme Your Skin Cells Run On
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. Think of it as a battery terminal for your cells — it helps shuttle the energy your skin needs to repair and renew itself. The catch: NAD+ levels decline as we age, and that's why it has become one of the most talked-about molecules in longevity science.
What NAD+ actually does
Your skin is one of the most metabolically demanding organs you have. It's constantly rebuilding the barrier, replacing surface cells, and repairing daily damage from UV and pollution. All of that costs energy, and NAD+ sits at the center of how cells produce it. It's a key player in the reactions that turn nutrients into usable cellular fuel, and it's a required partner for sirtuins — a family of proteins involved in cellular repair and stress response.
In lab and early research, raising or supporting NAD+ availability has been studied in the context of cellular energy, DNA repair pathways, and how cells respond to stress (NIH / NCBI overview of NAD+ metabolism).
Why people talk about it for aging
NAD+ concentrations decline with age — research suggests levels can fall substantially by midlife. Because NAD+ is tied to energy production and repair, the logic is straightforward: as the molecule that powers cellular maintenance becomes scarcer, the systems that keep skin resilient have less to work with.
That's the appealing part of the story. Here's the honest part.
What the science does — and doesn't — prove (yet)
Most of the strongest NAD+ research is about biology and metabolism, not about finished cosmetic products improving the look of skin in controlled trials. A 2026 systematic review looking specifically at NAD+ for skin aging concluded that while NAD+ shows clear biological activity, the clinical evidence for cosmetic anti-aging benefit is still inconclusive and needs larger, better-designed studies (2026 systematic review, PubMed).
We tell you this on purpose. A brand built on "science you can actually check" doesn't get to quote the flattering studies and hide the cautious ones. NAD+ is one of the most promising directions in longevity skincare — and it's still an emerging field.
How MISOORA uses NAD+
We include NAD+ in our AM Firming Serum, used as the morning step in the routine. We don't bury it in a "proprietary complex" — it's a disclosed active. Like every MISOORA formula, the serum is built to support the look of radiance and firmness over time, as part of a consistent routine, not as a single-bottle miracle.
The takeaway
NAD+ isn't a magic switch. It's a real, well-studied coenzyme at the heart of how skin cells make energy, paired with skincare evidence that is still maturing. That combination — genuine biology plus honest expectations — is exactly why it fits a longevity philosophy instead of an anti-aging promise.
