KAMURAHuman studies exist for different NAD-related compounds
Oral NR and topical niacinamide studies do not establish effects of a topical NAD+ cream.
Topical NAD+
NAD+ biology is real and important inside cells. That a cream raises NAD+ in your tissues in a way that changes how you age is not established — the molecule is large and skin is built to keep things out.
Systemic benefit from topical NAD+ is not established here
Check the exact ingredients, delivery route and preparation. An ingredient study does not establish the performance of every blend.
NAD+ cream · NAD topical · NAD+ skin serum
What is it?
A pharmacy or cosmetic compounder puts nicotinamide adenine dinucleotide (NAD+), or a precursor such as nicotinamide riboside, into a cream or serum applied to skin.
Why this formulation?
There is no approved medicine here to compare against. These are made because there is consumer demand for NAD+ in every possible form, following genuine interest in NAD+ decline with age.
What can the research tell us?
NAD+ falling with age, and its role in energy metabolism and DNA repair, is well supported. Oral and intravenous routes have been studied in humans with mixed results. Topical delivery is the least studied of all: NAD+ is a comparatively large, charged molecule and the skin barrier restricts absorption. Note that plain nicotinamide (vitamin B3) in skincare does have reasonable evidence for skin barrier and pigmentation — it is a different, smaller molecule, and results from it should not be credited to NAD+.
Read the supporting sources ↓What to discuss about alternatives
If the goal is skin quality, better-evidenced topicals exist — retinoids and niacinamide among them. If the goal is systemic NAD+, a skin cream is the least supported route available, and a different formulation needs its own evidence.
Contexts to discuss with a clinician
- Cosmetic skin use, where expectations are set at skin appearance rather than systemic or anti-ageing effects
Details worth checking
- Systemic anti-ageing claims made for a topical product
- Results from niacinamide research being presented as NAD+ evidence
- High price relative to better-studied skincare actives
