The short answer

NAD+ Firming Serum is built for skin that looks tired, thinner and less firm after 50. It tells you exactly how much NAD+ is inside (2,500 ppm), pairs it with NMN and ATP, and sits in a fragrance-free barrier base, so it firms the look of skin without the sting. In a 4-week trial, 93% of participants saw firmer-looking skin, and no irritation was reported.

01It targets the tired look at its source

If your skin looks more tired than you feel, energy is part of the story. NAD+ is the coenzyme your cells use to turn fuel into energy and to run their daily repair work. When researchers measured it in 49 human skin samples from people aged 15 to 77, NAD+ levels fell with age, in women and men alike.1 Reviews of the field link that decline to several hallmarks of aging.2

Most firming creams work on the surface. NAD+ Firming Serum is built around the cells’ energy supply, so it supports the work they do to keep skin looking firm, even and rested.

02It tells you exactly how much NAD+ is inside

Plenty of serums put NAD+ on the front of the box, then bury it in a “complex” with no number. You have no way to know if there is enough to matter.

We print it: 2,500 ppm of NAD+, right on the label. No guessing, no proprietary blend. If you like to know what you are putting on your skin, this is where trust starts.

03It feeds the whole energy pathway

NAD+ is a big molecule, about 663 daltons. Ingredients pass the skin barrier most easily when they are under roughly 500 daltons, which makes NAD+ hard to deliver on its own.3 So the serum doesn’t rely on one ingredient. It brings in smaller partners from the same pathway.

Ingredient Size Its job in the formula
NAD+ About 663 daltons The coenzyme cells use for energy and repair
NMN About 334 daltons A smaller building block of NAD+, easier to deliver
ATP About 507 daltons The energy currency cells spend every second

Together they support the whole energy chain, not just a single step, which is why tired-looking skin can look more rested and more radiant.

04The surprise: it’s gentle

Most people expect a firming serum to tingle, peel or make skin red for a while before it gets better. This one doesn’t.

Reason #4

Zero irritation reported. In our 4-week trial, participants reported no purging, no peeling and no sun sensitivity. The formula is fragrance-free and ethanol-free, made for mature, sensitive skin that reacts to everything.

No purgingNo breakout phase to push through.
No peelingIt isn’t an exfoliant, so skin stays smooth.
No sun sensitivityUse it every morning under SPF.

That gentleness is also why it layers so easily. It fits under moisturizer and makeup, and it works alongside retinal in a night routine.

05It firms without stripping your barrier

Older skin repairs its moisture barrier more slowly after it is disrupted.4 That is why harsh “firming” products often leave mature skin tight and uncomfortable. NAD+ Firming Serum sits in a barrier complex of the three lipids that hold the skin barrier together:

  1. Ceramide NPThe main structural lipid of the barrier. It helps skin hold on to water.
  2. CholesterolWorks with ceramides to keep the barrier flexible and sealed.
  3. Linoleic acidAn essential fatty acid that helps dry, mature skin feel comfortable again.

The result: skin looks firmer and feels softer and more cushioned, not stripped.

06You can see a difference in 4 weeks

FAQYour questions, answered

Can I use NAD+ serum with retinal?

Yes. Use NAD+ in the morning and retinal at night. The serum is designed to layer with everything else in the routine, including retinal.

Is it safe for sensitive skin?

It is fragrance-free and ethanol-free, and no irritation was reported in our 4-week trial. As with any new product, patch test first.

How long until I see results?

Many people notice more comfortable, hydrated skin in the first week. In our trial, 93% saw firmer-looking skin at 4 weeks. Results are cosmetic and vary from person to person.

Where should I apply it?

Face, neck and jawline, where thinning and loss of firmness tend to show first. Press it in, don’t rub.

Is a topical NAD+ serum the same as NAD+ supplements?

No. Supplements are taken into the body, while a serum is a cosmetic applied to the skin. A serum makes cosmetic claims only: how your skin looks and feels.
