United States · Facial serum · Single-product teardown
30 October 2026
EQQUALBERRY puts fourteen peptides, five ceramides, eight hyaluronates, NAD+ and NMN in one 30 ml bottle and sells it at $21.99. The formula is genuinely unusual. The reviews are not: hydration is praised, irritation and price are the two things that break it.
Everything below is drawn from four independent readings of the same SKU on the same day: the live listing, a price-tracker archive, and two ingredient databases - one of which refused to answer.

The five claims, as written
- REVITALIZING ENERGY & PEPTIDE SERUM BOOST: A delicious mix of NAD+ and an advanced peptide complex helps energize skin while signaling collagen production. This high-performance peptide serum supports firmer, smoother, and more resilient skin with every single drop!
- ANTI-AGING PEPTIDE BEAUTY BLEND: Replenishes NAD+ levels to counter skin decline linked to aging. This targeted peptide formula delivers authentic korean skincare innovation to help block wrinkle formation, restore skin vitality, and maintain long-term elasticity and youthful bounce.
- HYDRATION & RADIANCE CARE: Infused with antioxidant-rich pomegranate extract to fight free radicals, protect against dullness, and encourage collagen renewal. Leaves skin fresh, glowing, and smoothie-ready with an even-toned, radiant complexion.
- SKIN BARRIER STRENGTH WITH CERAMIDES: Five essential ceramides (NP, AP, AS, NS, EOP) plus vegan collagen deeply hydrate, restore the skin’s moisture shield, and defend against dryness and environmental stressors.
- LIGHTWEIGHT, NON-STICKY FINISH: Fast-absorbing, refreshing texture sinks into skin without residue. Ideal for daily use on the face, neck, and other body areas for a plump, radiant, glassy-glow finish.
Reading the claims against the label
Four of the five bullets are checkable against the declaration in section 03, and they hold: fourteen peptides are claimed and fourteen are declared, five ceramides named in the copy are all present, the NAD+/NMN pairing appears at positions 11 and 12, and pomegranate extract is in the botanical blend. The one claim that is not checkable is the most prominent - “Clinically Proven Firming & Glow”, painted across the third carousel frame with no study size, duration or endpoint anywhere on the listing. A reader should treat the clinical wording as unverified and the ingredient arithmetic as verified.

Product rating
A strong average built on a bimodal tail
7,183 ratings averaging 4.2 out of 5. The headline is healthy. The shape of the distribution is more interesting than the average: this is a product people either endorse or reject, with relatively little in between.

Star distribution
Why the tail matters more than the average
With 7,183 ratings, 68% five-star is a solid result and not a rounding artefact. The diagnostic detail is the relationship between the low buckets: 8% one-star against 4% two-star and 9% three-star. When the one-star bucket is larger than the two-star bucket, complaints are not gradations of dissatisfaction - they are failures. Read alongside the aspect table below, where skin irritation scores only 31% positive, the most defensible reading is that for a meaningful minority this formula does not suit their skin at all, and they say so bluntly. That is a different risk profile from a product that is merely underwhelming.
What buyers talk about, and how they split
Mentions per themed aspect, split positive and negative. Bars are ordered by volume.
| Aspect | Mentions | Positive | Negative | Positive share |
|---|---|---|---|---|
| effectiveness | 951 | 616 | 335 | 65% |
| moisturizing | 277 | 221 | 56 | 80% |
| value for money | 246 | 97 | 149 | 39% |
| glow | 164 | 140 | 24 | 85% |
| non-greasy | 107 | 65 | 42 | 61% |
| skin irritation | 106 | 33 | 73 | 31% |
| quantity | 56 | 16 | 40 | 29% |
The summary the platform itself gives
Customers report that the serum makes their skin feel hydrated and transforms its appearance, giving it a beautiful glow. The product receives mixed feedback about its effectiveness, with some finding good results while others say it didn't make a difference. Customers disagree on whether it's worth the money and its non-greasy feel, with some noting a sticky sensation. Skin reactions are also mixed, with some finding it doesn't irritate sensitive skin while others report breakouts and allergic reactions. The quantity receives criticism, with customers noting there isn't much product in the bottle.
Read this with one caveat
The listing rendered no individual review bodies on the capture date, at any of the three page variants or across three timed retries. Everything in this section therefore comes from the aggregate rating distribution, the platform's own themed aspect tallies, and its generated summary - not from quoted reviews. No reviewer can be identified here because none was read. Two interpretations are deliberately withheld: no cause is assigned to the irritation reports (niacinamide at position six is a plausible mechanism, not a proven one), and the value complaint is not converted into a per-ounce verdict, because the bottle's net content is 30 ml and buyers may be reacting to how fast a 30 ml serum runs out.

Product ingredients
Seventy declarations, forty-four of them actives
The merged ingredient reading. Both community databases failed to return anything for this SKU - one refused at the door, the other does not carry the brand - so this section rests on the manufacturer's own declaration, read in full and classified by role.
Distribution by level
Classified by the job each ingredient does, not by any safety score.
| Level | What it contains | Count | Share |
|---|---|---|---|
| L1 Base & humectant core | Water, solvents and the high-dose humectants that set texture | 6 | 9% |
| L2 Functional actives | Peptides, ceramides, hyaluronates, niacinamide, NAD+/NMN, botanicals | 44 | 63% |
| L3 Texture & stabiliser | Emollients, emulsifiers, thickeners, chelators, pH adjusters | 17 | 24% |
| L4 Preservation | Diol-based preservative boosters; no named preservative | 3 | 4% |
| Total | 70 | 100% |
Actives by family
Counted directly from the declaration, which makes two of the brand's claims testable.
Peptides
14 declared
The brand claims 14 types. The label declares 14. The claim is literally true.
Ceramides
5 declared
NP, NS, AS, AP, EOP - exactly the five the bullets name, correctly identified.
Hyaluronates
8 declared
One molecule in eight molecular forms - a marketing-led build for a hydration benefit.
What’s inside, in one paragraph
Six ingredients form the vehicle - water, butylene glycol, glycerin, an emollient ester, 1,2-hexanediol and betaine - and the other 64 do work. The active block is dense and unusually ordered: niacinamide sits at position six, which is a high dose for a serum; NAD+ and NMN follow at 11 and 12; then fourteen peptides run in an unbroken block from 13 to 26; then collagen, five ceramides and eight hyaluronates. Six berry and pomegranate extracts arrive at position 57 as a single antioxidant blend, and astaxanthin closes the list. Twenty of the seventy entries carry a peptide, ceramide or hyaluronate name - the formula is built to be read.

Fragrance, allergens, preservation
No fragrance is declared. There is no Parfum, no Fragrance and therefore no allergen list - the unscented claim is supported by the panel. Preservation is entirely diol-based, three entries and no named preservative: ethylhexylglycerin, caprylyl glycol and pentylene glycol, supported by 1,2-hexanediol in the base. That is the current Korean-market standard and it is gentler on paper than phenoxyethanol, but it also means a shopper scanning for a preservative will not find one. The ingredients most likely to provoke a reaction here are the niacinamide dose, the diols and the six-extract botanical blend - which is consistent with, though not proof of, the irritation complaints in section 02.
What the two databases would have added, and did not
COSDNA returned a browser-verification wall instead of a result page and was abandoned after the first read; it would have contributed per-ingredient acne-risk, irritant and safety scores. Skinsort carries no EQQUALBERRY product at all - two searches produced only its generic twenty-item fallback list - so its claim matrix, its concerns list and its comedogenicity ratings are all missing. Nothing was substituted from a similar product. The consequence is stated plainly: this report can tell you what each ingredient does in the formula, and cannot tell you whether any of them is comedogenic.

Product price
One channel, a fourteen-month record, and a price sitting on its own average
The tracker has never recorded an offer shipped and sold by Amazon for this ASIN. The entire price record is third-party supply, which makes the range narrow and the current position unusually typical.

The five fixed points, side by side
The dashed line is the price at capture. The high and the list price are the same number, which is what an undiscounted launch price looks like.
| Price type | Lowest ever | Highest ever | Current | Average |
|---|---|---|---|---|
| Amazon (first party) | no data | no data | no data | no data |
| 3rd Party New | $14.98 (23 Jun 2026) | $24.99 (18 Aug 2026) | $21.99 (17 Oct 2026) | $22.14 |
| 3rd Party Used | no data | no data | no data | no data |
The current value was last observed 13 days before collection and is corroborated by the identical $21.99 on the live listing at capture. It is a last-observation figure, not a live quote.
Position against its own history
| Benchmark | Reading | What it means |
|---|---|---|
| Current vs all-time low | +46.8% | $7.01 above the June floor |
| Current vs all-time high | -12.0% | $3.00 below the August ceiling |
| Current vs lifetime average | -0.7% | effectively at the mean - the least informative position possible |
| Current vs list price | -12.0% | the advertised 12% saving, confirmed |
| Average vs list price | -11.4% | the market has cleared below list for most of the record |
| Full recorded spread | $10.01 | a 66.8% swing within fourteen months |
The June-to-August swing is the whole story
A 66.8% range inside fourteen months, on a listing with only one channel, is not promotional pricing behaviour - it is supply behaviour. The August high of $24.99 is exactly the list price, so that reading is the product back at full price rather than a markup; the June low of $14.98 is 40.1% below list, which is what a restock-clearing seller does. Everything since has converged on $22, which is the lifetime average to within a rounding error. If you are buying, the actionable fact is that this SKU has cleared at $15 once in fourteen months and that a price alert set near $18 would have fired in that window.
Why there is no first-party series
The Amazon row is empty on all four columns. That does not mean the tracker failed - it means no offer shipped and sold by Amazon.com has ever been recorded for this ASIN. Every offer, including the one holding the buy box at capture, comes from third-party sellers. For a Korean indie serum imported into the US catalogue that is the normal structure, and it has a practical consequence: there is no first-party floor under the price, so the range is set entirely by competing resellers and their stock cycles.

Bottom line
What holds up, what does not
Holds up
- The ingredient arithmetic is honest: 14 peptides claimed, 14 declared; 5 ceramides claimed, 5 declared.
- Seventy declarations with 44 functional actives is a genuinely actives-led formula, not a vehicle with a token extract.
- No fragrance, no fragrance allergens - the unscented claim is supported by the panel rather than asserted.
- Glow and moisturising are the two best-scoring themes at 85% and 80% positive, and they are what the formula is built to deliver.
Does not hold up
- “Clinically Proven” appears on the packaging with no study size, duration or endpoint anywhere on the listing.
- Skin irritation is the worst-scoring theme at 31% positive, with 73 negative mentions and breakouts named explicitly.
- Value for money is the largest negative block at 149 mentions against 97 positive - a 30 ml bottle at $21.99 is being judged against what it costs per use.
- Fourteen peptides below position 12 cannot each be at study concentration; the block guarantees presence, not dose.
If you are deciding
For a buyer whose skin tolerates niacinamide and who wants a barrier-and-peptide serum in a light gel texture, the formula is stronger than its price suggests and the $15 low is achievable. For a buyer with reactive skin, the irritation theme is the single most reliable negative signal in this report and it is backed by 73 mentions, not by one bad review. For a seller studying this SKU, the lesson is structural: one channel, no first-party floor, a 66.8% annual range, and a review distribution split into endorsements and rejections rather than a smooth curve.

Method and confidence
How this was assembled, and where it is weak
| Element | Confidence | Basis |
|---|---|---|
| Specification table, claims, price at capture | High | Read directly from the live listing with a US delivery address, prices in native USD |
| Rating average and star distribution | High | Published aggregate, 7,183 ratings |
| Ingredient identity and order (70 entries) | High | Manufacturer declaration transcribed verbatim and counted |
| Level and family classification | Medium | Analyst scheme from each ingredient's role; not a source field |
| Individual review text | Not available | No review bodies rendered on the capture, at any page variant or retry |
| Comedogenic / irritancy ratings | Not available | One database blocked, the other does not carry the brand; nothing substituted |
| Price history | Medium | Five fixed points per price type, all-time only, no observation-level series |
What is a snapshot. Price, rank and rating are live values. The tracker's current price was last observed 13 days before collection; the rating total moves daily. Every figure here is dated to 30 October 2026.
What is a derivation. Every percentage, spread and position figure is computed from transcribed values and is labelled as such. No percentage is presented as a source figure.
What is an inference. Statements about why prices moved, why reviews split, or what drives irritation are labelled as inferential where they appear. Correlation in a review distribution is not causation, and the report does not claim it.
What is absent on purpose. No reviewer name, handle, profile or ID appears anywhere in this report, because no review text was obtainable. No source URLs are reproduced in the body. No ingredient concentration is estimated from label position.
