Does Topical NAD+ or Nicotinamide Riboside Do Anything for Skin?
The honest answer: the research on applying NAD+ or nicotinamide riboside (NR) to skin is early. Most of what we know about NR comes from oral supplements and laboratory studies, not from finished skincare tested on people. What topical NR can reasonably offer is support for skin's resilience as part of a well-built formula, not a reversal of ageing.
We use nicotinamide riboside in our formulas, so we have every reason to oversell it. We would rather explain what the science does and does not say.
What NAD+ is
NAD+ is a molecule every cell uses to turn nutrients into energy and run its daily maintenance. Research shows NAD+ levels tend to fall with age, which has made it one of the central topics of longevity science.
Why not just put NAD+ in a cream?
NAD+ itself is a relatively large, charged molecule, which makes it hard to get into skin and hard to keep stable in a formula. That is why formulators generally turn to its smaller building blocks, the precursors, which cells use to make their own NAD+.
What we know about NR
- Orally, NR has been studied in human trials and shown to raise NAD+ levels in the blood. That is the basis of its popularity as a supplement.
- In the laboratory, NR and other NAD+ precursors have been studied in skin cells for their role in energy metabolism and resilience to stress such as UV light.
- Topically, published human data on finished NR skincare is still limited. It is a promising area, not a settled one.
The precursor with the most skin evidence: niacinamide
Niacinamide is also a form of vitamin B3 and also an NAD+ precursor. Unlike NR, it has decades of topical research behind it for tone, the look of pores and the barrier. That is why our longevity formulas pair NR with niacinamide at 4%: one ingredient at the frontier of longevity research, one with a long topical track record.
How to judge a "NAD+ skincare" claim
- Be wary of promises to "boost NAD+", "activate mitochondria" or "reverse cellular ageing". These are biological claims a cosmetic cannot make.
- Look for named precursors (nicotinamide riboside, niacinamide) on the ingredient list, not just "NAD+ complex".
- Expect NR to be one part of a formula, alongside proven ingredients such as peptides and ceramides.
Why we include it
Vellura is built on the idea that the actives longevity-minded people already take as supplements belong in skincare too. Nicotinamide riboside is one of four longevity actives in our VX-8™ platform, alongside PQQ, ergothioneine and resveratrol. We describe it as what it is: an ingredient studied in longevity research, used to help skin look more resilient and radiant.
Questions
Should I take NR supplements instead?
Supplements and skincare do different things. Talk to your doctor before starting any supplement.
Is NR the same as niacinamide?
No. Both are forms of vitamin B3 and both are NAD+ precursors, but they are different molecules with different research histories.
