Mature Skin & Menopause · Ingredient Guide
You use good products, but after 50 your skin still looks tired, thinner and less firm. Part of the reason is energy: skin cells run lower on NAD+ as we age. Here is why most NAD+ serums still disappoint, and how to tell one that is built to work.
The short answer
NAD+ is a coenzyme your cells need to produce energy and repair themselves, and levels in skin fall with age.1,2 Most NAD+ serums disappoint for three reasons: the molecule breaks down in the bottle, it is too large to pass the skin barrier easily, or the dose is too small and hidden in a “complex.” Look for a disclosed concentration, protective packaging, smaller helper molecules such as NMN, and a barrier-friendly base. Then use it every morning, alongside retinal at night.
01Why skin looks tired after 50
Two things happen at once. First, menopause speeds up collagen loss: the American Academy of Dermatology estimates skin loses about 30% of its collagen in the first five years after menopause.3 Second, the cells that are supposed to rebuild it are running on less fuel.
In a study of 49 human skin samples from people aged 15 to 77, NAD+ levels showed a strong negative correlation with age, in both women and men.1 Less NAD+ means less energy for the daily maintenance work that keeps skin looking firm, even and rested.
02What NAD+ actually does in skin
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It is central to how cells turn nutrients into usable energy, and it is also consumed by the enzymes that repair DNA and manage cellular stress. Reviews in the field describe a decline in NAD+ with age across many tissues and link it to several hallmarks of aging.2
That is why NAD+ has become one of the most talked-about ingredients in longevity science. For skin, the logic is simple: support the cells' energy supply, and you support the work they do to keep skin looking firm and even. The catch is getting it to the cells.
daltons is the molecular weight of NAD+. Ingredients that pass the skin barrier easily tend to be under about 500 daltons, which makes NAD+ a hard molecule to deliver on its own.4
033 reasons NAD+ serums do nothing
- It breaks down before it reaches your face.NAD+ is sensitive to air, light and water. In a dropper bottle that is opened twice a day, some of it may degrade long before the bottle is finished. Packaging is part of the formula.
- It is too big to get through on its own.At about 663 daltons, NAD+ sits above the size that usually passes the skin barrier well.4 Smaller related molecules, such as NMN (nicotinamide mononucleotide, about 334 daltons), are part of the same NAD+ pathway and are easier to deliver.
- The dose is a rounding error.Many serums list NAD+ for the label, then hide it in a “proprietary complex” with no number. If a brand will not tell you how much is inside, assume it is very little.
04How to check an NAD+ serum before you buy
| Check | Good sign | Red flag |
|---|---|---|
| Concentration | A number in ppm or %, published by the brand | “Complex,” “blend” or no figure at all |
| Packaging | Airless pump or opaque bottle | Clear dropper bottle |
| Pathway support | NAD+ plus precursors such as NMN | NAD+ alone, low in the ingredient list |
| Base formula | Barrier lipids: ceramides, cholesterol, fatty acids | Alcohol and fragrance near the top |
| Made for | Mature, sensitive skin | “All ages,” with strong acids added |
05How our NAD+ Firming Serum is built
Built to pass the checklist
- 2,500 ppm NAD+, disclosed. The number is published, not hidden in a complex.
- NMN and ATP alongside NAD+, to support the whole energy pathway rather than one molecule.
- A barrier base of ceramide NP, cholesterol and linoleic acid, the lipids mature skin makes less of.
- Fragrance-free and ethanol-free, for mature, sensitive skin.
- For face, neck and jawline, where thinning tends to show first.

NAD+ works best as the morning step, under moisturizer and SPF. At night, retinal does the collagen-focused work. They support different things, so they combine well.

07What to expect, week by week
NAD+ is not a filler and it will not change your skin overnight. Here is a realistic picture of daily use.
Cosmetic results vary from person to person. Daily SPF and a consistent routine make the biggest difference.

Shop NAD+ Firming SerumKey takeaways
- NAD+ in human skin declines with age, in women and men.1
- After menopause, that energy dip meets fast collagen loss, about 30% in five years.3
- Most NAD+ serums fail on stability, delivery or dose.
- Check for a disclosed concentration, protective packaging, NMN and a barrier base.
- Use NAD+ in the morning and retinal at night, with SPF every day.
08FAQ
Can I use NAD+ serum with retinal?
Yes. Use NAD+ in the morning and retinal at night. Our NAD+ Firming Serum is designed to layer with everything else in the routine, including retinal.
Is a topical NAD+ serum the same as NAD+ supplements or IV drips?
No. Supplements and IV drips are taken into the body, while a serum is a cosmetic applied to the skin surface. They are not interchangeable, and a serum makes cosmetic claims only: how your skin looks and feels.
Is NAD+ safe for sensitive skin?
NAD+ itself is not an exfoliant, so it does not sting the way acids or strong retinoids can. Choose a fragrance-free, alcohol-free formula and patch test first, as with any new product.
Where should I apply it?
Face, neck and jawline, where thinning and loss of firmness tend to show first.
Does skincare replace hormone therapy?
No. Hormone therapy is a medical decision to discuss with your doctor. Skincare supports how your skin looks and feels.
