If you are choosing between numbuzin No.9 NAD+ BIO Lifting-sil Essence and EQQUALBERRY NAD+ Peptide Boosting Serum, do not treat them as two versions of the same NAD+ product.
They are not.
Both contain direct NAD+ and substantial peptide systems, but the formulas differ in texture, size, supporting ingredients, price, and the type of routine they fit best.
Quick verdict:
Choose numbuzin if you want a cushiony essence-serum, a larger 50mL size, a broad peptide-heavy formula, and a much stronger visible consumer track record.
Choose EQQUALBERRY if you want NAD+ plus NMN in a formula built around 14 peptide ingredients, five ceramides, cholesterol, squalane, panthenol, and multiple hydrating ingredients.
Formula-first pick: EQQUALBERRY, based on its disclosed NAD+ + NMN, five-ceramide, cholesterol, squalane, panthenol, and peptide architecture.
Cushiony texture, larger size, and broader consumer-demand pick: numbuzin.
This is an editorial comparison of the finished formulas—not evidence that EQQUALBERRY has stronger NAD+ activity.
Neither product can be declared the stronger NAD+ serum because their direct NAD+ concentrations are not publicly disclosed in a standardized, comparable way.
The real question is:
Which finished formula better matches your skin goal?
numbuzin NAD+ vs EQQUALBERRY NAD+: Quick Comparison
Choose numbuzin if you want:
- 50mL instead of 30mL
- a cushiony essence-serum texture
- a broad peptide-focused formula
- stronger firming and plumping positioning
- a product with thousands of visible reviews on its U.S. store
- better regular-price value per milliliter
Choose EQQUALBERRY if you want:
- direct NAD+ plus NMN
- 14 peptide ingredients
- five ceramides
- cholesterol
- squalane
- panthenol
- multiple forms of hyaluronic acid
- a fresher, faster-absorbing serum format
My Overall Pick
Formula-first: EQQUALBERRY
Size + cushiony texture + consumer-demand: numbuzin
Neither wins on NAD+ alone.
What Are You Actually Comparing?
NAD+ skincare is still an emerging cosmetic category.
NAD+ has legitimate roles in cellular biology, but that does not automatically prove that every retail skincare product containing NAD+ produces a clinically meaningful anti-aging effect.
So this comparison does not assume:
more NAD+ = better skincare
or:
more scientific-looking ingredients = stronger results
Instead, we compare what consumers can actually evaluate:
- current ingredient lists
- supporting actives
- formula structure
- product size
- texture
- price
- finished-product testing
- current availability
- intended skin goal
If you want the science first, read our guide to what NAD+ skincare actually does.

Formula Comparison: numbuzin vs EQQUALBERRY
Both formulas contain direct Nicotinamide Adenine Dinucleotide, or NAD+.
Both also contain familiar supporting ingredients such as:
- niacinamide
- glycerin
- peptides
- cholesterol
- adenosine
- hydrating ingredients
But the complete formulas follow different strategies.
numbuzin No.9 NAD+ BIO Lifting-sil Essence: Formula Breakdown
numbuzin No.9 NAD+ BIO Lifting-sil Essence is currently sold in a 50mL size.
numbuzin markets No.9 around:
NAD+ + 50 Peptides
Its current ingredient list includes direct Nicotinamide Adenine Dinucleotide and a very large peptide system.
Other notable ingredients include:
- niacinamide
- glycerin
- dimethicone
- shea butter
- cholesterol
- sodium hyaluronate
- beta-glucan
- ATP
- tocopherol
- resveratrol
- glutathione
- fermented ingredients
- numerous peptides
This is not a minimalist NAD+ serum.
numbuzin has a more cushiony, emollient-rich essence-serum feel than a minimalist watery serum.
It may suit users who enjoy a more substantial hydrating finish, but texture perception will vary by skin type, routine, and the amount applied.
What Are You Actually Buying?
A better description is:
a peptide-heavy firming essence-serum that also contains NAD+.
That matters because visible softness, hydration, temporary plumping, and smoother skin can also come from the surrounding humectants, emollients, silicones, and peptides.
NAD+ does not need to explain every benefit of the finished product.
EQQUALBERRY NAD+ Peptide Boosting Serum: Formula Breakdown
EQQUALBERRY NAD+ Peptide Boosting Serum is currently sold in a 30mL size.
EQQUALBERRY lists direct:
Nicotinamide Adenine Dinucleotide
and additionally contains:
Nicotinamide Mononucleotide, or NMN.
Its current formula includes:
- niacinamide
- 14 peptide ingredients
- five ceramides
- cholesterol
- squalane
- panthenol
- shea butter
- soluble collagen
- allantoin
- adenosine
- multiple forms of hyaluronic acid
- astaxanthin
The five ceramides are:
- Ceramide NP
- Ceramide NS
- Ceramide AS
- Ceramide AP
- Ceramide EOP
What Are You Actually Buying?
A more useful description is:
an NAD+ + NMN peptide serum with a substantial barrier-supporting lipid system.
That gives EQQUALBERRY a clear cosmetic reason to exist even if you remain cautious about dramatic NAD+ longevity claims.
Which Has the Better Overall Formula?
For shoppers prioritizing barrier-supporting architecture, my editorial pick is:
EQQUALBERRY.
The reason is its combination of:
- NAD+
- NMN
- peptides
- five ceramides
- cholesterol
- squalane
- panthenol
- multiple humectants
But this is an editorial formula judgment, not proof of clinical superiority.
numbuzin is built around a different idea:
a cushiony, peptide-heavy firming essence-serum.
Formula-First Pick
EQQUALBERRY
Cushionier Firming Formula Pick
numbuzin
NAD+ vs NAD+ + NMN: Does EQQUALBERRY Automatically Win?
No.
EQQUALBERRY contains both NAD+ and NMN.
NMN is involved in NAD+ metabolism, but it is not simply “extra NAD+.”
You cannot create a meaningful consumer potency score by saying:
NAD+ + NMN > NAD+
The combination makes EQQUALBERRY more interesting from an ingredient-architecture perspective.
It does not establish that the product has a stronger clinically proven NAD+ effect.
NAD-Related Ingredient Variety
EQQUALBERRY
Proven NAD+ Effect
No winner
Which Has the Better Peptide Formula?
This is where marketing numbers can become misleading.
numbuzin officially markets the essence with 50 types of peptides.
EQQUALBERRY identifies 14 peptide ingredients.
It is tempting to conclude:
50 > 14, therefore numbuzin is better.
That is not scientifically useful.
A peptide count does not tell us:
- the concentration of each peptide
- stability
- delivery
- whether every peptide contributes meaningfully
- whether 50 peptides outperform 14
- which peptide contributed to a measured result
Peptide Breadth
numbuzin
Peptide + Barrier Architecture
EQQUALBERRY
Which Is Better for the Skin Barrier?
On paper:
EQQUALBERRY.
It combines five ceramides with:
- cholesterol
- squalane
- panthenol
- shea butter
- multiple humectants
That creates a clearer barrier-lipid architecture.
numbuzin is still moisturizing.
It includes:
- glycerin
- shea butter
- cholesterol
- beta-glucan
- sodium hyaluronate
- silicones and emollients
But its main identity is more clearly:
firming + peptides + cushiony essence-serum
rather than:
ceramide-focused barrier serum
Barrier Formula Pick
EQQUALBERRY
Which Has the Better Texture?
Texture is preference-driven.
numbuzin describes No.9 as a thread-like elastic essence, and its formula includes emollients, silicones, shea butter, fatty alcohols, and other ingredients consistent with a more substantial essence-serum feel.
It should not be interpreted as universally heavy.
Some users may experience it as lightweight but cushiony depending on application amount and what is layered underneath or above it.
EQQUALBERRY positions its serum as fresh and fast-absorbing without a heavy residue.
It still contains squalane, shea butter, and barrier lipids, so that does not mean completely weightless.
More Cushioning
numbuzin
Faster-Absorbing Positioning
EQQUALBERRY
Which Is Better for Dry Skin?
Both can make sense.
numbuzin gives you:
- cushionier texture
- glycerin
- shea butter
- cholesterol
- beta-glucan
- sodium hyaluronate
EQQUALBERRY gives you:
- five ceramides
- cholesterol
- squalane
- panthenol
- shea butter
- multiple hyaluronic-acid forms
For dry skin with barrier concerns, I would lean toward:
EQQUALBERRY
For dry skin that mainly wants a more substantial, cushiony firming layer, numbuzin may be more satisfying.
Which Is Better for Oily or Combination Skin?
I would lean toward:
EQQUALBERRY
mainly because of its faster-absorbing serum positioning.
But it is not an ultra-minimal gel serum.
It still contains:
- squalane
- shea butter
- lipids
- multiple humectants
numbuzin’s more cushiony essence-serum profile may simply feel like more product than some oily-skin routines want.
Which Is Better for Sensitive Skin?
There is no automatic winner.
Both products have long, complex ingredient lists.
EQQUALBERRY contains several ingredients commonly used in barrier-supporting formulas, including:
- ceramides
- panthenol
- squalane
- allantoin
That is appealing on paper.
But it also contains multiple botanical extracts and many other ingredients.
numbuzin likewise contains a very large peptide and supporting-ingredient system.
If your skin is highly reactive:
Do not assume “barrier,” “repair,” or “NAD+” automatically means gentle.
Introduce one new product at a time.
Which Is Better for Fine Lines?
numbuzin has the clearer wrinkle-focused finished-product positioning.
The official U.S. page reports a four-week finished-product test covering the appearance of 11 wrinkle areas.
That is useful product-specific information.
However, the public product page does not provide enough methodological detail to establish independent clinical superiority over EQQUALBERRY.
It also does not show that NAD+ alone caused the reported results.
EQQUALBERRY also presents lifting- and elasticity-related finished-product testing.
Again, that evaluates the complete formula rather than isolating NAD+ or NMN.
Finished-Product Wrinkle Positioning
Advantage: numbuzin
Proven NAD+ Anti-Wrinkle Effect
No winner
If fine lines are your primary concern and you want an ingredient category with substantially more established direct human evidence, retinoids remain a different evidence tier from current topical NAD+ cosmetics.
Which Has Better Finished-Product Evidence?
Both brands provide product-specific claims, which is more useful than borrowing general NAD+ research.
numbuzin
The official U.S. product page reports four-week wrinkle-focused finished-product testing.
The public description does not provide enough methodological detail to treat that claim like an independently evaluated clinical paper.
EQQUALBERRY
Brand materials present lifting- and elasticity-related finished-product testing.
That likewise does not isolate NAD+ or NMN.
Evidence Verdict
No decisive winner.
Neither product has shown that its NAD+ component is clinically superior to the other’s.
Which Is More Popular?
numbuzin, by a large margin based on the visible U.S. review base.
Its official U.S. store currently shows thousands of reviews for No.9 NAD+ BIO Lifting-sil Essence.
EQQUALBERRY currently shows a much smaller visible review base on U.S. retail listings.
Review counts are not controlled evidence of efficacy.
They do, however, indicate that numbuzin currently has:
- broader visible consumer exposure
- substantially more accumulated feedback
- stronger established demand on that platform
Consumer-Demand Pick
numbuzin
Which Is Better Value?
Using regular prices checked on August 26, 2026:
numbuzin
$33 / 50mL
Approximately:
$0.66 per mL
EQQUALBERRY
$24.99 / 30mL
Approximately:
$0.83 per mL
At regular price, numbuzin offers more product per dollar.
Current promotional pricing can change quickly. At the time of this update, both products were also showing discounted U.S. pricing, so always check the current retailer price before purchasing.
Best Regular-Price Value by Volume
numbuzin
Prices change, so a temporary sale should not become the main reason for choosing the formula.
Which Is Better If You Care About NAD+ Concentration?
Neither can honestly be declared the winner.
The current public product information does not provide a standardized direct-NAD+ concentration comparison that supports a potency ranking.
And even if both products disclosed concentration in identical units, a larger number would not automatically establish:
- better stability
- better delivery
- better skin penetration
- better wrinkle results
- better finished-product performance
So there is no legitimate:
“stronger NAD+ serum”
winner here.
Which Would I Actually Buy?
If I were choosing based on the finished formula rather than NAD+ hype, I would pick:
EQQUALBERRY NAD+ Peptide Boosting Serum.
The reason is not simply that it contains NAD+ plus NMN.
If I mentally remove those two trendy ingredients from the marketing, I am still left with:
- niacinamide
- 14 peptides
- five ceramides
- cholesterol
- squalane
- panthenol
- multiple humectants
- allantoin
- adenosine
That gives the product a coherent reason to exist as a barrier-supporting, firming-oriented serum.
But I would choose numbuzin instead if I wanted:
- 50mL
- a more cushiony essence-serum feel
- a broader peptide system
- stronger wrinkle-focused positioning
- a much larger visible consumer track record
- better regular-price value per milliliter
So the conclusion is:
EQQUALBERRY is my formula-first pick.
numbuzin is my cushiony-texture, size, and established-demand pick.
numbuzin vs EQQUALBERRY: Category Winners
Best overall formula architecture: EQQUALBERRY
Best for barrier support: EQQUALBERRY
Best for NAD+ + NMN: EQQUALBERRY
Best for cushiony texture: numbuzin
Best for peptide breadth: numbuzin
Best regular-price value per mL: numbuzin
Best consumer track record: numbuzin
Best finished-product wrinkle positioning: numbuzin
Best proven NAD+ efficacy: No winner
That last result matters most.
Neither product has established that its NAD+ component is clinically superior to the other’s.
Can You Use numbuzin and EQQUALBERRY Together?
Potentially, but most people probably do not need both in the same routine.
There is substantial overlap:
- NAD+
- niacinamide
- peptides
- moisturizing ingredients
- firming positioning
Using both may increase cost and routine complexity without providing a clearly established additional benefit.
If you already own both, alternating them may make more sense than assuming they need to be layered.
For placement, follow our Korean skincare routine order guide and consider texture from thinner to more substantial.
Which One Should You Buy?
Buy numbuzin if you want:
- 50mL
- cushiony essence-serum texture
- a broad peptide system
- a more established consumer product
- better regular-price value per milliliter
- firming-focused skincare with a more substantial finish
Buy EQQUALBERRY if you want:
- NAD+ + NMN
- 14 peptides
- five ceramides
- cholesterol
- squalane
- panthenol
- faster-absorbing serum positioning
- stronger barrier-supporting architecture on paper
Skip Both if:
Your only reason for buying is the belief that topical NAD+ has already been proven to reverse skin aging in an ordinary retail serum.
That conclusion is ahead of the evidence.
The Bottom Line
numbuzin No.9 NAD+ BIO Lifting-sil Essence and EQQUALBERRY NAD+ Peptide Boosting Serum are both interesting choices within the emerging Korean NAD+ skincare category.
But they win for different reasons.
EQQUALBERRY wins on barrier-focused formula architecture, including NAD+ + NMN, five ceramides, cholesterol, squalane, panthenol, and peptides.
numbuzin wins on size, peptide breadth, cushiony essence-serum texture, established consumer demand, and regular-price value per milliliter.
If I were choosing strictly by the finished formula, I would buy EQQUALBERRY.
If I wanted a more cushiony firming essence-serum, more product, and a substantially larger visible consumer track record, I would buy numbuzin.
Neither wins simply because of NAD+ alone.
Choose the finished formula—not the biggest scientific-sounding claim.
Frequently Asked Questions
Is EQQUALBERRY NAD+ Better Than numbuzin NAD+?
EQQUALBERRY is my formula-first pick because it combines NAD+, NMN, peptides, five ceramides, cholesterol, squalane, and panthenol.
numbuzin may be the better choice if you want a cushionier essence-serum, a larger 50mL size, broader peptide system, or much stronger visible consumer demand.
Which Has More NAD+?
The current public product information does not support a standardized direct-NAD+ concentration comparison between the two.
Do not infer potency from product names or marketing.
Does EQQUALBERRY Contain NMN?
Yes.
Its current ingredient information lists both Nicotinamide Adenine Dinucleotide and Nicotinamide Mononucleotide.
Does numbuzin No.9 Really Have 50 Peptides?
numbuzin officially markets No.9 NAD+ BIO Lifting-sil Essence as containing 50 types of peptides, and its current ingredient list contains an unusually large peptide system.
That does not prove that 50 peptides outperform a formula containing fewer peptides.
Which Is Better for Dry Skin?
Both may work.
EQQUALBERRY has the clearer barrier-lipid architecture.
numbuzin provides a more cushiony essence-serum experience.
Which Is Better for Sensitive Skin?
Neither is automatically suitable for every sensitive skin type because both formulas are complex.
Introduce either product gradually if your skin is reactive.
Which Is Better for Fine Lines?
numbuzin has the clearer wrinkle-focused brand-reported finished-product positioning.
That does not prove that NAD+ alone caused the reported results or establish independent superiority over EQQUALBERRY.
Which Is Cheaper?
EQQUALBERRY has the lower upfront regular price.
At regular price per milliliter, numbuzin is cheaper because it contains 50mL versus 30mL.
Temporary sales can change the comparison.
Can I Use Both Together?
Potentially, but their purposes overlap enough that most routines probably do not need both.
Which One Would You Buy?
EQQUALBERRY for formula architecture.
numbuzin for cushiony texture, larger size, broader peptide system, and consumer track record.
