I Tested 4 NAD+ Firming Serums: Here's What Actually Held Up
If loose skin or new fine lines have you reading ingredient lists at midnight, one serum keeps getting name-dropped in every skincare thread. I spent months putting the most talked-about NAD+ firming serums on my own face to see which ones actually tighten and smooth, and which are just pretty bottles of nothing.

Why NAD+
What to Look For
Top 4
Why Most Firming Serums Never Do Your Skin Any Good
You've probably heard that NAD+ is the molecule your skin cells run low on as you age, and that feeding it back can help skin behave younger. That part holds up. Pair NAD+ with EGF and collagen and you're giving tired skin the actives it needs to firm up and bounce back.
So you bought a bottle. Used it for a few weeks. Kept checking your jaw and your under-eyes in the mirror. And nothing really changed.
Here's what I figured out: the actives work. The problem is that most serums on the shelf are padded with cheap fillers or dose the good stuff so low it barely does anything, so nothing real ever reaches your skin.
Once I understood what a real NAD+ serum actually contains, three things decide whether a bottle firms your skin or just sits there doing nothing.
The 3 Things Every Real NAD+ Serum Must Have
1.
Real Actives: EGF, NAD+ and Collagen You Can Point To
A firming serum lives or dies on its actives. The ones that move the needle name EGF, NAD+ and collagen right on the label, not buried behind a wall of water and glycerin. A lot of cheaper bottles lean on fragrance and slip agents so they feel nice going on but do almost nothing underneath. If you can't find the actual firming actives near the top of the ingredient list, you're paying for the padding.
2.
Honesty: A Full Ingredient List, No Hiding
A brand that trusts its formula shows you the whole thing. You want the full INCI list printed where you can read it, with the firming actives sitting high enough to matter. The market is flooded with serums that shout "NAD+" on the front and then hide a thin, watered-down formula on the back. Read the full list, not just what the front of the bottle promises.
3.
Proof: Real Reviews and Clinical Results
A good serum should have receipts. That means a real base of customer reviews, not a handful of stock testimonials, plus actual numbers on firmness, hydration and fine lines. The bottles I trusted could point to thousands of ratings and measured results after a couple of weeks. The ones I skipped had two reviews and a vague promise. If nobody can show you it works, assume it doesn't.
Top 4 NAD+ Serums Of 2026
I put the four most talked-about serums to the test and scored each one on what actually decides results: real actives, an honest formula, proof it works, and value.
1. meimei EGF NAD Firming Serum
by meimei
A+
Overall Grade
Pros
Honest one-list formula: EGF, NAD+ and Collagen up front, no filler actives, nothing padded
Real firming actives: EGF plus NAD+ and Collagen work on fine lines and slack skin at the source
Deep hydration that lasts: sinks in fast, softens wrinkles, and leaves skin plump without any greasy film
Firmer, bouncier skin: testers logged +33.1% elasticity and +29.4% fewer fine lines in two weeks
Instant moisture boost: +36.8% hydration measured after the very first application
Lightweight and gentle: non-greasy, dermatologist-friendly, easy to use morning and night
60-Day Money Back Guarantee: don't see firmer skin and you get your money back
Loved by thousands: a 4.9 out of 5 rating pulled from 25,320 verified reviews
Best value: buy one get one free, a 2-pack for $35 instead of $90
Cons
You can only buy it on the official meimei site
The buy-one-get-one bundles sell out fast during big drops
The Verdict:
meimei was the one serum that never made me second-guess it. If you want firmer, smoother skin without wading through a wishlist of buzzy actives, everything that matters is right here.
You get a straight, honest ingredient list built around EGF, NAD+ and Collagen, not a bloated formula stacked to look impressive on the box.
The proof sealed it for me. Testers saw +29.4% fewer fine lines and +33.1% more firmness in two weeks, plus a +36.8% hydration jump after the first use.
And the reception backs it up. A 4.9 out of 5 rating across 25,320 reviews. A little goes a long way, and you get 60 days to decide if it's for you.
The Bottom Line:
Plenty of serums lean on vague peptide blends or padded ingredient lists. meimei is built for people who want their skin to actually change, not a pretty label full of promises.
You get real EGF, NAD+ and Collagen actives that absorb fast and go to work, with buy one get one free, a 2-pack for $35 instead of $90.
Nothing on the label is filler, so every drop earns its place. And the 60-Day Money Back Guarantee means if you don't see firmer skin, you get your money back. That's plenty of time to judge whether it works for you.

2. numbuzin No.9 NAD+ Bio Lifting-sil Essence
by numbuzin
A-
Overall Grade
Pros
NAD+ & Peptides: NAD+ plus a 50-peptide complex
Loved by Reviewers: 4.9/5 across 2,505 reviews
Proven Hydrators: Niacinamide, sodium hyaluronate, beta-glucan
Clean Formula: Cruelty-free and gluten-free
Bundle Value: Multi-packs drop the per-bottle cost
Cons
Brand Study: Its "11 wrinkle types in 4 weeks" claim may not hold for everyone
Mid-Premium: One 50 mL bottle runs $33
Texture Is Personal: The silky thread "sil" feel won't suit everyone
Value Needs a Bundle: One bottle costs more per use than our winner
The Verdict:
numbuzin gets a lot right. It leans on NAD+ and a 50-peptide complex, then backs it up with K-beauty hydrators people already trust like niacinamide, sodium hyaluronate and beta-glucan. It also has the deepest review base in this lineup, 4.9 out of 5 from 2,505 buyers, and that kind of social proof is hard to wave away.
It slips behind meimei on a few things. The EGF firming punch is not in this formula, and at $33 a bottle the cost per use climbs higher. The brand's own wrinkle claim reads a touch optimistic too, so I'd treat it as a starting point rather than a promise.
The Bottom Line:
If meimei ever sells out, numbuzin is the one I'd grab next. The silky essence texture comes down to taste and you do pay a bit more per use, but the actives are legit and thousands of buyers stand behind it. A genuinely strong second place.

3. Medicube EGF NAD+ Firming Serum
by Medicube
B+
Overall Grade
Pros
Same Active Trio: EGF, NAD+ and collagen, like the winner
Easy On The Wallet: A full 30 ml bottle for $26
Skin Tested: Non-comedogenic and irritation checked
Face + Neck: Made for both, no artificial colorants
Cons
Just 2 Reviews: On-site social proof is nearly empty
Unproven At Scale: Too few users to judge consistency
In-House Study: Clinical claims come from its own institute
New-Wave Actives: EGF and NAD+ lack long-term independent data
No Outside Testing: Efficacy not confirmed by third parties
The Verdict:
Medicube is the nearest thing on this list to the meimei formula. It runs the same headline actives, EGF (SH-Oligopeptide-1), NAD+ and Collagen Extract, in a 30 ml bottle that costs $26. On paper it matches my top pick almost active-for-active, and it's non-comedogenic and irritation-tested, so it's a sensible fit for face and neck.
Where it wobbles is proof. There are only 2 reviews on the site right now, so I have next to nothing that tells me how it wears over weeks. The "clinically proven" line points back to an institute the brand itself references, and EGF and NAD+ still don't have much long-term independent research behind them.
The Bottom Line:
If you want the meimei active story for less, Medicube gets you close, and $26 for a 30 ml face-and-neck serum is a fair deal. I'd wait for a real review base to build before I called it, though. For now the near-empty ratings and brand-only clinical claims are what keep it below the top spots.

4. Eqqualberry NAD+ Peptide Boosting Serum
by EQQUALBERRY
B
Overall Grade
Pros
Densest Active Stack · NAD+, NMN, a 14-peptide complex and a 5-ceramide complex
Lowest Price Here · All those actives for $24.99
Barrier-Supportive · Multiple hyaluronic acids, vegan-formulated
Cons
Thin social proof so far, only 25 reviews to go on
Vegan-formulated, but the vegan claim isn't actually certified
A very long ingredient list that can be a lot for one routine
Concentrations are never stated, so the real strength of the NAD+ and peptides is a guess
Small 30 ml Bottle · not much to work through that whole active list
The Verdict:
Eqqualberry is the budget pick, and on paper it looks stacked. You get NAD+, NMN, a 14-peptide complex, a 5-ceramide complex and a few hyaluronic acids for $24.99, which is the lowest price in this whole lineup. If you love reading an ingredient list, this one goes on forever.
The Bottom Line:
My hesitation is proof. None of those actives come with stated concentrations, so I can't tell whether the NAD+ and peptides are doing real work or just padding the label. Add 25 reviews and a vegan claim that was never certified, and you have the biggest ingredient list on this list with the least evidence it performs. Fine for a low-risk try at 30 ml, but you're mostly buying the promise.

Real clinical numbers: +33.1% elasticity and +29.4% fewer fine lines in two weeks
One honest ingredient list, nothing buried or padded out

Lightweight and non-greasy, sinks in fast for morning and night
60-Day Money Back Guarantee (real time to judge it)

That brand is meimei.
Why meimei Is Different
Most anti-aging serums are built by marketers chasing a fat margin.

That's why every box gets ticked here. Real EGF, NAD+ and Collagen at levels that do something, backed by clinical numbers and 25,320 reviews, cost more to make, and it's the only way to get you a result you can actually see in the mirror.
