What this is. A Korean 30 ml serum that sells volume rather than exfoliation: hydrolysed collagen under 300 daltons, 5% Volufiline, niacinamide, and seven forms of hyaluronic acid in a cream-in-serum texture.
What the data says. 4.3 stars on 3,401 ratings, $23.00 against a $26.00 list, and a third-party price history that has ranged from $15.56 to $26.00 since early 2024. The rating is good, not exceptional, and the price today sits 6.0% above its own all-time average.
What this report does differently. It reads the claim matrix, the 50-row ingredient list and the price record against each other rather than in sequence. The order follows the buying decision: what the product is, how it is rated, what is inside it, what it costs.

1. Product Information
The listing is unusually dense for a serum at this price. Five bullets, a thirteen-row specification block, a nine-image gallery and a comparison table that positions this bottle at the top of a seven-product line. Read together, they describe a product with a clear thesis: that fine lines and a flat-looking face are a volume problem, and that volume can be addressed topically.
The thesis is worth separating from the evidence. The listing commits to low-molecular-weight collagen and 5% Volufiline by name and concentration, which is more specific than most K-beauty listings manage. It does not commit to any measured outcome, and the ingredient table shows why: the collagen family occupies sixteen rows but most of it sits in the masking and conditioning blocks rather than acting as an active.

Three listing images are published for this ASIN and all three are shown. No buyer photographs exist in the gallery for this product, so there is no user-generated imagery to set beside the brand renders.
1.3 The claims on the listing
| Claim as written | What it commits to |
|---|---|
| Ultra-low molecular weight collagen under 300 daltons | A specific molecular-weight claim. Small enough to be described as penetrating, though the listing gives no assay to support the 300-dalton figure. |
| 5% Volufiline | A named concentration for the hydrogenated polyisobutene and Anemarrhena root extract blend. Verifiable against the ingredient list: both components appear, at positions 4 and 20. |
| Niacinamide-enriched | Niacinamide is present at position 9, which is early enough to be meaningful at typical use levels. |
| Safe for sensitive skin | A tolerance claim, not a test result. The formula is fragrance-free and alcohol-free, which supports it without proving it. |
| Korean skincare gift positioning | Commercial framing rather than a product claim; noted because it explains the packaging emphasis in the gallery. |
2. Product Rating
The headline is 4.3 out of 5 across 3,401 ratings. That is a good score for a serum in a crowded category and a slightly soft one for a product with a viral reputation, where the expectation set by the marketing is closer to 4.6.
The distribution explains the average better than the average explains the product: 70% five-star is a strong core, but a 7% one-star tail is roughly double what a well-tolerated moisturiser carries. A serum that either visibly works or visibly fails, with little middle ground, produces exactly this shape.
2.1 How the ratings are distributed
| Stars | Share | Approximate ratings |
|---|---|---|
| 5 stars | 70% | 2,381 |
| 4 stars | 11% | 374 |
| 3 stars | 8% | 272 |
| 2 stars | 4% | 136 |
| 1 stars | 7% | 238 |
Read the two tails rather than the peak. The 70% five-star block is the product working as advertised for a large share of buyers, and the 11% four-star block is the near-miss group who liked it without being converted. Together they are 81%, which is the honest measure of satisfaction.
The 18% sitting at three stars or below is the number that matters for a first purchase. On 3,401 ratings that is roughly 600 people who were not convinced, split almost evenly between a 4% two-star band and a 7% one-star band. The one-star band alone is larger than the two- and three-star bands combined.
2.2 What buyers say, in the platform's own summary
Customers find the serum effective and deeply moisturizing, with one noting that a little goes a long way. The product makes skin look smooth and glowy, with many receiving compliments about their appearance, and one customer specifically mentioning improved eye and forehead fine lines. While some customers say it doesn't irritate their skin, others report breakouts, and opinions about value for money are mixed, with some finding it excellent while others say it's not worth the price. The product's durability receives mixed feedback, with some saying it lasts well while others report it doesn't last.
The platform summary is more useful than usual here because it names the conflict rather than smoothing it: effectiveness and glow are praised, while irritation and value are contested. Note the phrase about breakouts. It is the only place in the aggregated text where a negative outcome is attributed to the product rather than to expectations.
2.3 Which themes drive the score
| Aspect | Mentions | Positive | Negative | Positive share |
|---|---|---|---|---|
| effectiveness | 505 | 373 | 132 | 74% |
| moisturizing | 250 | 199 | 51 | 80% |
| skin feel | 151 | 139 | 12 | 92% |
| value for money | 130 | 85 | 45 | 65% |
| glow | 116 | 108 | 8 | 93% |
| skin irritation | 94 | 49 | 45 | 52% |
| plumping | 77 | 65 | 12 | 84% |
| duration | 54 | 31 | 23 | 57% |
Eight aspects with real mention counts, so the ranking can be read as a ranking. Effectiveness leads at 505 mentions and 74% positive, which is a solid but not emphatic result for the single largest theme.
The interesting column is the last one. Skin feel scores 92% positive on 151 mentions and glow scores 93% on 116, while skin irritation sits at 52% on 94 mentions. A product can be pleasant and still provoke reactions, and that is precisely what these two rows say together: the texture is not the problem, the tolerance is.
Value for money at 65% on 130 mentions is the second-weakest row and the one most likely to move with price. At $23.00 for 30 ml, the product is being judged as a premium serum, and roughly a third of the people who mention value do not accept the premise.
2.4 A second, much smaller reading
One further number sits outside Amazon: a community ingredient database scores the same product 3.8 out of 5 from three ratings. Three ratings is not a sample, and it is included only so the two readings are not confused. The Amazon figure of 4.3 from 3,401 carries the weight; the 3.8 does not.
2.5 What the rating cannot tell you
- A rating is an average of expectations as much as of results. This product arrived with a viral reputation, which raises what counts as a five.
- No review text was captured, so no theme in this report is attributed to a named reviewer. The aspect counts are the platform's own aggregation.
- 3,401 ratings span a product that launched in 2024, so the score mixes early-adopter enthusiasm with later, more routine purchases.
- The 7% one-star tail is the most decision-relevant number on the page and the least explained by the platform summary, which mentions breakouts but does not quantify them.
3. Product Ingredients
Coverage: 50 of 50 ingredients. The full ingredient table was captured in one pass, so the list below is the complete formula in INCI order rather than an excerpt. The secondary channel was unavailable, so no cross-check was possible; no row has been invented to fill the gap.
3.1 The ingredients, in order
Fifty rows. Read them as four movements: a water-and-humectant opening, an emollient and emulsifier middle that gives the product its cream-in-serum body, a long collagen and amino-acid block, and a hyaluronic tail. Position is the only concentration signal a published INCI list carries, so the ordering is the analysis.

| 48 | Hydrolyzed Sodium Hyaluronate | Skin Conditioning | — | — |
| 49 | Sodium Hyaluronate Crosspolymer | Humectant | — | — |
| 50 | Potassium Hyaluronate | Skin Conditioning | — | — |
Only 6 of 50 rows carry any published comedogenic or irritancy rating, and the coverage is skewed towards the humectants. A blank cell means the source publishes no rating, not that the ingredient is clean. 3 rows carry a comedogenic value above zero: Hydrogenated Polyisobutene at 1 with an irritancy of 2, Butylene Glycol at 1 with an irritancy of 0, and Tocopherol at a 0-3 range. The product's own concern flag, Chondrus Crispus Extract, carries no numeric rating at all, only a precautionary note.
3.2 What the formula is actually built around
Hydrogenated Polyisobutene at position 4 and Anemarrhena Asphodeloides Root Extract at position 20 are the two halves of the Volufiline blend the listing names at 5%. Position 4 is early enough that the concentration claim is credible; position 20 is late enough that the botanical half is a supporting player rather than a lead.
Sixteen rows belong to the collagen and amino-acid family: hydrolysed collagen, soluble collagen, atelocollagen, hydrolysed elastin and a run of single amino acids from glycine to isoleucine. This is a humectant and film-forming block, not a rebuilding one. Soluble collagen cannot cross the stratum corneum at its molecular size.
Seven hyaluronic forms plus glycerin, glycereth-26, butylene glycol and glutamic acid make hydration the most heavily staffed function in the formula, with 25 ingredients credited for it. That is also why skin feel scores 92% positive while effectiveness scores 74%.
Two things stand out when the list is read against the marketing. First, the product is fragrance-free by omission rather than by declaration: there is no fragrance row and no essential oil, which is a stronger guarantee than a label claim. Second, the texture is carried by Hydrogenated Polyisobutene, Neopentyl Glycol Diheptanoate and Dicaprylyl Carbonate even though the claim matrix says oil-free and silicone-free. Those claims are technically true, but they do not mean the product is light.
Adenosine at position 15 is the one wrinkle-directed active with a recognised mechanism, and it sits in the middle of the list rather than at the top. At the concentrations used in Korean anti-wrinkle products, that is normal; adenosine is effective at 0.04% and does not need to lead the formula.
3.3 Function groups: where the ingredients go
| Group | Count | Ingredients |
|---|---|---|
| Humectants | 11 | Glycerin, Glycereth-26, Butylene Glycol, Glutamic Acid, Sodium Hyaluronate, Soluble Collagen et al. |
| Emollients | 5 | Hydrogenated Polyisobutene, Neopentyl Glycol Diheptanoate, Dicaprylyl Carbonate, Hydrolyzed Collagen, Hydrolyzed Elastin |
| Solvents and texture | 3 | Propanediol, Hydroxyethylcellulose, Cellulose |
| Emulsifiers | 1 | Trilaureth-4 Phosphate |
| Skin conditioning and protecting | 16 | Water, 1,2-Hexanediol, Niacinamide, Hydrolyzed Collagen Extract, Ethylhexylglycerin, Adenosine et al. |
| Antioxidants | 2 | Tocopherol, Cysteine |
| pH, buffering and chelating | 3 | Disodium EDTA, Sodium Acetate, Glycine |
| Masking and amino acids | 7 | Serine, Aspartic Acid, Alanine, Arginine, Tyrosine, Phenylalanine et al. |
| Other | 2 | Threonine, Hydroxypropyltrimonium Hyaluronate |
Skin conditioning and protecting is the largest group at 11 rows, but that is an artefact of how the source labels collagen and amino acids rather than evidence of a conditioning-led formula. Merge it with the humectant block and the real shape appears: this is a hydration and film-forming product with a small active core.
3.4 Classification by position: the concentration ladder
Because INCI order is a concentration ranking, the most defensible level classification is positional. The four bands below split the 50 rows into a lead block, a core support block, a trace block and a tail, and the tail is where the marketing claims live.
| Band | Positions | Count | What sits there |
|---|---|---|---|
| Lead actives | Positions 1-10, the top of the INCI order | 10 | Water, Glycerin, Propanediol, Hydrogenated Polyisobutene, Neopentyl Glycol Diheptanoate, Glycereth-26, 1,2-Hexanediol, Dicaprylyl Carbonate et al. |
| Core support | Positions 11-25 | 15 | Hydrolyzed Collagen Extract, Trilaureth-4 Phosphate, Hydroxyethylcellulose, Ethylhexylglycerin, Adenosine, Disodium EDTA, Sodium Acetate, Cellulose et al. |
| Trace and buffer | Positions 26-40 | 15 | Hydrolyzed Collagen, Soluble Collagen, Alanine, Lysine, Arginine, Tyrosine, Phenylalanine, Proline et al. |
| Tail | Positions 41-50 | 10 | Methionine, Hydrolyzed Elastin, Hydroxypropyltrimonium Hyaluronate, Atelocollagen, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate et al. |
The lead block is ten rows and it is almost entirely the vehicle: water, glycerin, propanediol, two emollient esters, glycereth-26, 1,2-hexanediol, dicaprylyl carbonate, niacinamide and butylene glycol. Niacinamide at position 9 is the only functional active in the top ten, and it is doing real work there.
The tail is where the story gets thin. Positions 41 to 50 include hydrolysed elastin, atelocollagen and six hyaluronic forms, which sounds impressive and is present at concentrations that the position ordering itself tells you are low. That does not make them useless, but it does mean the collagen rebuild narrative rests on rows that cannot carry it.
3.5 What the product claims, and how the claims hold up
Twelve claim badges are published. Ten hold and two fail, and both failures are the kind that matter to a specific buyer rather than to everyone.
| Claim | Status | Note |
|---|---|---|
| Alcohol-free | Holds | No denatured alcohol or drying alcohol in the list |
| EU-allergen-free | Holds | No EU-listed fragrance allergen present |
| Fragrance-free | Holds | No fragrance or essential oil row; the Amazon listing also states Fragrance Free |
| Oil-free | Holds | No triglyceride or plant oil; the emollients are synthetic esters |
| Paraben-free | Holds | No paraben in the preservative system, which runs on 1,2-hexanediol and ethylhexylglycerin |
| Silicone-free | Holds | No silicone row despite the creamy texture |
| Sulfate-free | Holds | No sulfate surfactant |
| Cruelty-free | Holds | Brand self-declaration only, with no third-party certification on the page |
| Fungal-acne-safe | Holds | No malassezia-feeding ester or polysorbate flagged |
| Reef-safe | Holds | No UV filter or ingredient banned under reef legislation |
| Pore-clogger-free | Not met | One precautionary flag: Chondrus Crispus Extract |
| Vegan | Not met | Animal-derived collagen and elastin are present, so the claim cannot hold |
The two failures are Vegan and Pore-clogger-free. Vegan fails for a structural reason: the formula is built on animal collagen and elastin, so no reformulation short of abandoning the product's thesis would fix it. Pore-clogger-free fails on a single precautionary flag, and the source is careful to say that a flag is not a prediction.
Two passes deserve a caveat. Cruelty-free is a brand self-declaration with no third-party certification visible, so it is marked as holding on the brand's word rather than on evidence. Fungal-acne-safe is a negative finding: nothing in the list is flagged as malassezia-feeding, which is a weaker statement than a positive test.
3.6 Concerns worth knowing before you buy
One flagged ingredient, Chondrus Crispus Extract, carrying a precautionary comedogenic note rather than a tested rating. The source itself states a flag does not mean the finished product will clog pores.
One concern, and it is the acne flag on Chondrus Crispus Extract. The mechanism claimed is precautionary, based on related ingredients and user reports rather than a test on this extract, and the same source notes that the widely circulated 5-out-of-5 comedogenic rating for carrageenan has no traceable experimental basis. Treat this as a watch item for anyone who already reacts to algae-derived ingredients, not as a warning for everyone else.
3.7 The benefits, ranked by how many ingredients carry them
| Benefit | Description | Ingredients | Weight |
|---|---|---|---|
| Hydrating | Raises water content and relieves tightness | 25 | |
| Anti-aging | Softens the look of lines and supports firmness | 12 | |
| Scar healing | Improves the look of marks and texture | 7 | |
| Barrier repair | Reinforces the skin's own barrier and limits water loss | 7 | |
| Reduces irritation | Calms discomfort and improves tolerance | 5 | |
| Redness reducing | Eases visible flushing | 4 | |
| Brightening | Restores light to dull skin | 2 | |
| Good for oily skin | Balances oil without stripping | 2 | |
| Dark spots | Evens tone and fades the look of marks | 2 | |
| Acne fighting | Works on congestion and oil | 1 | |
| Reduces large pores | Improves the visible size of pores | 1 | |
| Skin texture | Smooths rough patches | 1 |
Twelve benefits and the ranking is informative. Hydration at 25 supporting ingredients is more than double the next entry, which matches the formula: the humectant and hyaluronic blocks are the product's centre of gravity. Anti-aging at 12 is the claim the marketing leads with and the second-largest group, while the single-ingredient benefits at the bottom of the table are supporting notes rather than reasons to buy.
3.8 Key ingredient groups
| Group | Mechanism as published | Ingredients |
|---|---|---|
| Hyaluronic acid | Draws and holds water across several molecular weights | 5: Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer |
| Antioxidants | Neutralises free radicals and limits oxidative stress | 2: Tocopherol, Cysteine |
| Vitamin E | Fat-soluble antioxidant that also stabilises the formula | 1: Tocopherol |
| Niacinamide | Supports the barrier, balances oil and improves tone | 1: Niacinamide |
Four key groups, and the imbalance is the point. Hyaluronic acid is carried by five ingredients and niacinamide by one, yet niacinamide sits at position 9 and the hyaluronic forms cluster from position 23 onwards. The group with the most members is not the group with the most concentration.
4. Product Price
Two prices matter and they are not the same price. The listing sells at $23.00 with a $26.00 list reference and a 16% Subscribe & Save tier at $21.85. The third-party tracker records a current market observation of $22.28 from 30 October 2026, one day before this capture, and no current Amazon offer at all.
The gap between those numbers is small enough to ignore for a single purchase and large enough to matter for the read: at $23.00 the product is at the top of its own recent band, and the $22.28 tracker value suggests the buy box has recently been held by a marketplace seller rather than by Amazon.
4.1 Today's price
The $26.00 list price is a manufacturer reference, not a price anyone has paid recently. The tracker's own list-price field reads $18.18, which is $7.82 below the Amazon reference and closer to what the product has actually transacted at. Two list prices for one SKU is a red flag on the discount badge: the 12% saving is measured against the higher of the two.
4.2 The full price record
| Price type | Lowest ever | Highest ever | Current | Average |
|---|---|---|---|---|
| Amazon | $18.70 | $26.00 | — | $23.22 |
| 3rd Party New | $15.56 | $26.00 | $22.28 | $21.01 |
| 3rd Party Used | — | — | — | — |
Two of the three rows are incomplete, and that is the finding rather than a gap. Amazon has no current offer recorded, so the Amazon row carries historical values only, and the used market has never been tracked for this ASIN. Any comparison across channels here is a comparison across different time windows.
Four bars per channel: all-time low, all-time average, current and all-time high. The Amazon series has no current bar because Amazon is not currently selling, which is why it stops at three.
The third-party series is the one to read. Current sits between the average and the high, closer to the average, which is the signature of a product that is neither discounted nor at its ceiling.
4.3 Where the current price actually sits
| Benchmark | Amazon | 3rd Party New |
|---|---|---|
| Current versus all-time low | +43.2% | $15.56 |
| Current versus all-time average | +6.0% | $21.01 |
| Current versus all-time high | -14.3% | $26.00 |
| Current versus list price | +22.6% | $18.18 |
Position against four benchmarks, expressed as the percentage difference between the current $22.28 observation and each reference. Negative means the current price is below the benchmark.
The spread from -14.3% to +43.2% is the whole decision range. Buying today costs 43.2% more than the best price the product has ever traded at, and the all-time low is only ten months old, so it is not a stale artefact from a launch promotion.
4.4 Volatility and the averages
| Price type | All-time spread | Spread as % of low | Average vs list |
|---|---|---|---|
| Amazon | $7.30 | 39.0% | 27.7% |
| 3rd Party New | $10.44 | 67.1% | 15.6% |
Volatility is high on both channels, and the third-party spread of 67.1% is the more meaningful figure because that channel has been active continuously.
The Amazon average of $23.22 sits 27.7% above the tracker's list price, which tells you the Amazon-held periods were the expensive ones. That is consistent with the buy box having moved to third-party sellers at a lower price.
4.5 The channel comparison
The channel picture is a handover rather than a competition. Amazon held the buy box through 2025 at an average of $23.22, with a high of $26.00 in early August 2025 and a low of $18.70 three weeks later. From 2026 the third-party channel took over and immediately traded lower, hitting $15.56 in January 2026 before climbing back to $26.00 in March.
Today's page price of $23.00 is $0.72 above the third-party current observation of $22.28 and close to the Amazon historical average. In practice that means the price on the page is being set by a marketplace seller at a level near what Amazon used to charge, not at the competitive level the third-party channel reached in January.
4.6 Timeline of the dated extremes
| Date | Event | Price | Channel |
|---|---|---|---|
| 2025-08-04 | Amazon all-time high | $26.00 | Amazon |
| 2025-08-28 | Amazon all-time low | $18.70 | Amazon |
| 2026-01-12 | 3rd Party New all-time low | $15.56 | 3rd Party New |
| 2026-03-19 | 3rd Party New all-time high | $26.00 | 3rd Party New |
Four dated extremes in twenty months. The tightest pair is the two Amazon events in August 2025, a $26.00 high on the 4th and an $18.70 low on the 28th, three weeks apart. A 28% move inside one month on the same channel is a promotion pattern, not a market repricing, and it should not be read as evidence that $26.00 was ever a sustained price.
The 2026 extremes tell a different story. The third-party low of $15.56 in January and the high of $26.00 in March are two months apart and bracket the range the channel has traded in since. That is a genuinely competitive seller field.
4.7 What this means for the purchase decision
- The all-time low of $15.56 was reached ten months ago on the third-party channel, not by Amazon, so it is a repeatable event rather than a one-off launch price.
- Today's $23.00 is 6.0% above the all-time average and 43.2% above the low. That is a normal price, not a good one.
- The 12% discount badge is measured against a $26.00 reference that the tracker contradicts with an $18.18 list price. Treat the badge as marketing.
- Subscribe & Save at $21.85 is within 4.0% of the all-time average and is the cheapest route to the product without waiting for a dip.
- $22.77 per fluid ounce is premium for 30 ml. On a per-millilitre basis, this is priced like a treatment, so judge it against treatments rather than against essences.
5. Who It Is For
| A good fit if you… | Look elsewhere if you… |
|---|---|
| want a plumper, smoother look and are willing to pay for texture | want a proven collagen-rebuilding treatment, which no topical collagen delivers |
| have dry or dull skin and want a fragrance-free serum that layers under sunscreen | have fungal-acne-prone skin and react to ester-heavy emulsions |
| have tried watery hyaluronic serums and found them too light | want a strictly lightweight, oil-free gel |
| react badly to algae or carrageenan-family extracts | expect a 4.5-plus rating and a long record of consistent reviews |
| want a K-beauty gift with a clear, photogenic routine step | are shopping on unit economics: $22.77 per fluid ounce is premium for 30 ml |
One practical note that the listing does not make: the texture is a cream-in-serum, which means it behaves like a light lotion and can pill under a heavy sunscreen. Two pumps is the volume the listing implies, and at 30 ml that is roughly six to eight weeks of twice-daily use.
6. Method and Confidence
| Element | Confidence | Basis |
|---|---|---|

6.1 Limitations, stated plainly
- No review bodies were captured. Both the desktop page and the mobile page returned zero inline reviews across four attempts, so no quotable review text appears in this report and none was reconstructed.
- No buyer photos exist for this ASIN. The listing exposes image tiles for the brand gallery only, so the gallery below shows three listing images and no user photography.
- The ingredient ratings come from a single channel. The secondary channel was unreachable, so the acne and irritant scores that source normally supplies are absent rather than filled in.
- Comedogenic and irritancy columns are sparse: most rows carry no published rating, and a blank is not a zero.
- Position in the INCI list is a proxy for concentration, not a measurement. Two ingredients in the same band can differ by an order of magnitude.
- Price history is all-time only. A six-month or one-year low cannot be produced from this source, and the current Amazon offer is empty because Amazon is not holding the buy box.
- The 28 million bottles claim is the brand's own footnote and is not independently verified here.
- Everything in this report is a snapshot taken on 31 October 2026. Rank, price and review counts move.
Snapshot date 31 October 2026. All prices in US dollars as published for a US delivery address; no currency conversion applied. Reviewer identities are withheld throughout. Ingredient ratings are community-sourced and describe ingredient classes, not this finished formula.
