The bank holds no serum product photography, no bottle or dropper frames and no bathroom-shelf frames, a gap the honesty section admits. The frame is the subject itself: the face, in warm light, which is the only place these bottles are ever used.
Checked and updated October 2026
The short version. One basis, published in full below: the record the maker prints, because a serum is the one product in the bathroom sold purely on its actives, and its ingredient list is the only evidence there is. The Ordinary’s niacinamide serum wins at 89, both its actives dosed in its name, niacinamide second on an 11-item list, at $6.00 the ounce. The dose column, counted, is this run’s contrast: a headline active with a printed percentage stands behind 6 of 8 bottles here, against 1 of 8 on the eye shelf at Card No. 90. The exceptions carry the page: a seventh bottle prints its dose in Europe and withholds it in America, and the skip names five actives and doses none. The fragrance column: a Parfum entry on 1 of 8 lists, at the tail of the ranked-last bottle, and a scented oil on the skip’s. A second named active carries a printed dose on 1 of 8. Four of the eight bottles circulate two ingredient lists. And the arithmetic the shelf hopes goes unread: $6.00 to $88.06 the ounce.
First, the decision
One product, named before anything is scored: buy The Ordinary Niacinamide 10% + Zinc 1%. Its published list runs 11 items and is printed on its card: water, niacinamide second, pentylene glycol, zinc PCA fourth, and a short functional tail. Both of the actives in its name are dosed in its name, 10 percent and 1 percent, the only bottle in the field that measures its second ingredient as well as its first. No fragrance entry, no scented oil, no alcohol, at $6.00 for a full ounce at Ulta. On a shelf where the grooming run has spent ninety Cards reading headline actives standing undosed at the tails of lists, this bottle is the inversion: the shortest list here, the fullest disclosure here, and the cheapest ounce here, in one $6 bottle. Its deductions are printed on its card: its directions print no drop count, and no panel stands behind the SKU on the captured record, so its evidence is its document, which is the strongest document on the page.
Now the species paragraph, because the shelf hides it and the ranking depends on it. A serum shelf is four jobs graded as one ranking. Vitamin C is the morning antioxidant, brightening and tone. The retinoids, retinol and retinal, are the night shift, texture and fine lines, dosed a few nights a week. Niacinamide is the regulator, tone and oil, worn morning and night. Hyaluronic acid is the water layer, a support act that holds moisture at the surface and seals nothing. Neither species is the honest one. Each is graded on the fullness of its list and the truth of its claims against that list; a water layer is not charged for lacking a treatment active, which is not its job, and a retinoid is not credited for hydrating, which is not its own. The species is named on every card, so a reader comparing across jobs can see the seam. What no species may do on this page is sell an ingredient its list does not measure. The bottle that measures none of its five headliners is ranked eighth.
The by-need rulings, one line each, printed here so a reader can leave with his answer before the cards:
Most faces, most routines: the winner (89), the regulator, dosed at both names, worn morning and night under whatever is already on the shelf.
Lines and texture, the night brief: the Naturium retinal (84), its dose printed in its name at the middle of a three-strength ladder, 2 to 3 pumps, three nights a week at most, the cap printed by its maker.
Brightening, with a panel behind it: the Timeless (81), 20 percent with a third-party trial printed; the CeraVe tube (79) for the reader who wants his vitamin C sealed, dosed and fragrance-free from the pharmacy school.
The water layer: The Ordinary’s hyaluronic serum (79), $9.90 the ounce, under a moisturizer, because a serum of this species seals nothing and this one does not pretend to.
And the use rule, stated plainly once: serum goes on clean skin, before moisturizer, and the dose is the count the maker prints where one is printed. The retinoids here are night bottles; the vitamin C bottles here are morning bottles; sunscreen closes the morning. Where a maker prints 2 to 3 drops or 1 to 2 pumps, that count, not an instinctive squeeze, is what the bottle’s price and panel were built on.
The dose column: the shelf that measures
Count the field the way the grooming Cards count, and this shelf breaks the run’s pattern. A headline active with a printed percentage stands behind six of the eight bottles on the maker’s own record: niacinamide at 10 percent with zinc at 1 percent, retinaldehyde at 0.10 percent, vitamin C at 20, 10 and 15 percent across its three bottles, and hyaluronic acid at 2 percent, that last figure a combined total across five forms of the acid, a qualification its card prints. Set it against the shelves behind it in this run: one dosed bottle in eight on the eye shelf, a soothing active dosed on none of eight aftershaves, a name scent arriving as an ingredient on none of four beard oils that carry one. The serum shelf doses because the serum is sold on the active, and the active is the claim, and here, unusually, the claim is measured where a buyer can read it. The column’s failures are therefore specific, and this page names them rather than spreading them. One bottle, the La Roche-Posay retinol, prints its 0.3 percent in its maker’s European materials and withholds the number from its American page, a dose that exists on one continent’s document and not the other’s. One bottle, the skip, names five actives and measures none. And the column’s quieter count: a second named active carries a printed dose on one bottle in eight, the winner’s zinc. Behind every other first number, the partner ingredient rides on position alone, ferulic acid eleventh, vitamin E fourteenth, panthenol ninth, which is why the honesty row credits the first dose in full and the second only where it is printed.
The fragrance column: one Parfum, one scented oil
A Fragrance or Parfum entry, the single word behind which a scent formula hides: on one of the eight lists, at the very tail of the ranked-last bottle, the La Roche-Posay retinol, twenty-third and last of 23, in a serum sold by the sensitive-skin house of the pharmacy shelf. A second bottle scents itself openly: the skip’s grapefruit peel oil, twelfth of 25, which its maker’s texture copy calls a natural fragrance and sells as a feature. Six lists carry neither, the winner, the retinal, the Timeless, the CeraVe tube, the hyaluronic serum and the booster all publishing fragrance-free records, at prices from $6.00 the ounce up, which settles the standing excuse: fragrance-free is not a premium feature on this shelf, it is the field’s default. The column’s second count is the drying alcohol: alcohol denat. stands inside the top six on two of the eight lists, sixth on the CeraVe vitamin C’s, fourth on the La Roche-Posay’s, printed in the open on both, charged on their cards as record, not as concealment. What the column proves, read whole, is that this shelf’s makers can write a clean list when the category asks for one. The two who scent a leave-on active product are not following their shelf. They are leaving it, and the scores say so.
The two-list column: four bottles, eight documents
The grooming run’s recurring paperwork problem stands at its widest on this shelf: four of the eight bottles circulate two ingredient lists. The Paula’s Choice booster was streamlined from 25 items to 17 under the same name, the same dose and the same price, its earlier cast, ergothioneine ninth, two peptides, a hyaluronate, dropped from the current list while American retail highlights still sell the dropped antioxidant by name. The Ordinary’s hyaluronic serum grew from 17 items to 23 under its name, gaining the ceramide blend its current copy leads with, a change the maker discloses on its retail pages, tinge and all. The Timeless vitamin C’s current 11-item list drops the fragrance an older formula carried, while a 12-item rendering with glycerin and laureth-23 still circulates. And a European retailer’s rendering of the CeraVe vitamin C prints an older phosphate-salt formula where the maker’s coded list prints the pure acid second. The desk grades the maker’s current list in every case, prints the divergence on every card, and draws the column’s conclusion plainly: on this shelf, the document a reader checked last year may not be the document in this year’s bottle, and the makers who disclose the change, in their FAQs and their retail copy, are graded differently from the ones whose retail pages go on selling the old cast. The list is the evidence. When the evidence moves, the honest maker says so on the record.
How the scores work
Every bottle is scored out of 100 on its published record, under a basis settled for this shelf in the grooming run’s five-row shape: ingredient and claim honesty, 30 (the fullness of the published list, where the headline actives and any fragrance entry sit, and the maker’s claims read against that list, a dosed claim credited only where a percentage is printed); the active record, 20 (the named species’ record as printed, its dose and its position, its panel evidence at its printed size, and the packaging that doses it); fit and range, 20 (which skin and which routine the bottle actually serves, its species and its strength ladder counted as fit facts, its scent load and its sizes); value per ounce, 15 (the checked shelf price divided by the bottle, printed in the table below so the arithmetic can be checked); and longevity and service, 15 (the stability of the formula record, the maker’s published service behind the product, and the house’s standing). Nothing here is a use test. This desk opened no bottle, wore no serum, and claims no measurements: a high score means the published record is strong. Two bottles stand level, the CeraVe vitamin C and The Ordinary’s hyaluronic serum at 79, and the tie is ruled on the honesty row, 26 to 22, printed on both cards: the tube doses its active and publishes its coded list entire, the water layer’s headline figure is a combined total with its named partner undosed.
Seven ranked, and the one sent home
The Ordinary Niacinamide 10% + Zinc 1%
A niacinamide serum, and the shortest document in the field, so it is printed here entire: water, niacinamide second, pentylene glycol, zinc PCA fourth, dimethyl isosorbide, tamarind seed gum, xanthan gum, isoceteth-20, ethoxydiglycol, phenoxyethanol and chlorphenesin, 11 items in all. Read it as what it is: a formula with nowhere to hide, a named vitamin at second in a list too short for garnish, and the only label in the field that measures both of its headline actives, niacinamide at 10 percent and zinc at 1 percent, the second dose being the rarest printing on this shelf, standing on one bottle in eight. The retailer panel prints the rest of the record plainly: formulated without fragrance, directed morning and evening before heavier creams, positioned for oily skin. That is what the honesty row’s 28 buys. Two deductions are printed plainly. The directions print no drop count, whole-face application without a number, one of the three unnumbered doses in the field. And no panel stands behind this SKU on the captured record: the house publishes clinical panels for other bottles, the hyaluronic serum fifth on this Card among them, and none for this one, so the winner’s evidence is its document rather than a trial, graded as such. The house’s wider record stands as evidence and is not transferred: its caffeine serum took second on Card No. 90 at 84, and its hyaluronic bottle stands fifth here at 79, a shelf this desk has now graded three times and found printed in full every time. At $6.00 for a full ounce it is the cheapest ounce here by a factor its value row pays in full: the bottle that tells you the most charges you the least, and on this shelf that is not a slogan, it is the table.

Naturium Retinaldehyde Cream Serum 0.10%
A retinal cream serum, 37 items on the published list: water, glycerin second, propanediol, a run of emollients and emulsifiers, phenoxyethanol seventeenth, and retinal twentieth, followed by the ferment and botanical tail, guanosine, uracil, tocopherol thirtieth and the preservative close. The position is printed here because this page prints positions, and it is read fairly: a 0.10 percent dose stands behind the preservative because 0.10 percent is a small number, and the maker prints the number itself, in the product’s name, which is the transaction the honesty row exists to reward. Retinal is the retinoid one conversion step from the active form where retinol takes two, the standard account of the species, and the maker builds the bottle around the fact: a sustained-release encapsulation stated in its copy, a cream base for the dry and the sensitive, and a strength ladder, 0.05, 0.10 and 0.15 percent, every rung dosed in its name, the only ladder on this shelf. The directions print the discipline: an even layer of 2 to 3 pumps to face, neck and chest, up to three nights a week, moisturizer after. The maker’s clinical record, carried in its retail listings, is a study of 34 subjects over two and four weeks printing 100 percent improved brightness, 100 percent improved texture and 97 percent improved elasticity, graded at its size on the active row. No Parfum entry stands anywhere on the 37. At 1.7 ounces it is the biggest bottle in the field, and its pill leads to the merchant’s Naturium serum shelf, where the bottle and its price stand as printed; its exact product page is a November capture, stated here rather than tidied away.

Timeless 20% Vitamin C + E Ferulic Acid Serum
A vitamin C serum, 11 items on the maker’s current published list: water, ethoxydiglycol, L-ascorbic acid third, propylene glycol, alpha tocopherol fifth, polysorbate 80, panthenol seventh, ferulic acid eighth, sodium hyaluronate ninth, benzyl alcohol and dehydroacetic acid. The dose leads the name, 20 percent, the strongest printed vitamin C figure in the field, and its two named partners stand inside the top eight, undosed, their positions printed here as the only public trace. The maker’s banner prints NO FRAGRANCE, DYE FREE, and the current list cashes it. The divergence is printed plainly, because this shelf’s paperwork moves: a 12-item rendering with glycerin, laureth-23 and triethanolamine still circulates, and the maker’s own ecosystem records that an earlier formula carried a fragrance the current list drops; the desk grades the current 11 and names the refresh a refresh. What lifts the active row to the field’s best 18 is the evidence: a third-party trial of 21 participants over 28 days, printed with its results, 81 percent improved complexion, 76 percent less dull, 71 percent brighter and smoother, a small panel and a short one, graded at its size and credited for existing at all on a shelf of assertions. The directions print a measured dose, 1 to 2 pumps, and the maker’s own arithmetic, an ounce lasting about a month at that rate, which the value row reads both ways: honest guidance, and about $28 a month, every month, for the brightest bottle here. The maker adds the species’ discipline in print: refrigerate it, use it within three to six months of opening.

CeraVe Skin Renewing Vitamin C Serum
A vitamin C serum in a sealed opaque tube, 26 items on the maker’s coded list, F.I.L. D231277/1: water, ascorbic acid second, glycerin third, dimethicone, cetearyl ethylhexanoate, alcohol denat. sixth, sodium hydroxide, the taurate thickener, panthenol ninth, and then the barrier cast the house is known for, ceramide NP tenth, ceramide AP eleventh, ceramide EOP twelfth, with sodium hyaluronate sixteenth, cholesterol eighteenth, tocopheryl acetate twentieth and phytosphingosine twenty-fifth. The maker prints the dose itself, 10 percent pure vitamin C, L-ascorbic acid, which puts this bottle in the dosed six and its house’s documentation habit on the record again. The charges are two, both printed in the open by the maker’s own list. The drying alcohol stands sixth, ahead of the ceramides the tube is sold on, a tension the active row prices: the barrier cast works behind a solvent the barrier does not need. And a European retailer’s rendering of this tube circulates an older phosphate-salt list in place of the coded one, the two-list pattern named in the column above; the desk grades the maker’s F.I.L. list and prints the divergence. No drop count stands in the directions, apply daily to face, neck and chest, one of the field’s three unnumbered doses. It stands level with the hyaluronic serum behind it at 79 and ahead on the tie ruling printed in the basis section, the honesty row, 26 to 22: a dosed active and a coded list entire, against a combined total and an undosed partner. The house’s wider record stands as evidence: its eye cream won Card No. 90 at 87, and this tube is that documentation habit in a second category.

The Ordinary Hyaluronic Acid 2% + B5
A hyaluronic serum, 23 items on the current published list: water, sodium hyaluronate second, propanediol, pentylene glycol, hydrolysed hyaluronic acid fifth, the crosspolymer sixth, phospholipids seventh, sphingolipids eighth, panthenol ninth, and the humectant and preservative tail. The name’s figure is printed here with its qualification entire: the 2 percent is a combined total across the formula’s forms of the acid, five of them in the current version, low, medium and high molecular weights, a crosspolymer and a hydrolysed form, a sum the maker’s long copy states and the bottle’s front does not. The B5 of the name is panthenol at ninth, undosed, the field’s second-name pattern again. The ceramide blend the current copy leads with arrives on the list as its lipid carriers, phospholipids and sphingolipids at seventh and eighth; no ceramide NP, AP or EOP entry stands on this list, a precision the card prints because the sibling shelf, the CeraVe tube above it, names its ceramides outright. The reformulation is disclosed where the two-list column said it would be: the original list ran 17 items, the current 23, and the maker’s retail pages disclose the change and the slight yellow tinge the new raw material brings, which is the honest way to move a formula, and the honesty row’s 22 credits the disclosure while charging for the summed headline and the undosed partner. A clinical study of 34 subjects applying twice daily stands on its retail record, a panel at the field’s standard size. It stands level with the CeraVe tube ahead of it at 79 and behind on the honesty ruling, 22 to 26, printed on both cards. At $9.90 the ounce, $8.75 in the two-ounce size, it is the water layer at its honest price: a support act, documented like one.

Paula’s Choice C15 Brightening Super Booster
A vitamin C booster, 17 items on the maker’s current published list: water, ascorbic acid second, dipropylene glycol, propanediol, glycerin, ethoxydiglycol, sodium hydroxide, the emulsifier pair, bisabolol tenth, ferulic acid eleventh, sodium phytate, decylene glycol, tocopherol fourteenth, and the ferment and preservative close. The front of the document is the field’s most professional: 15 percent pure vitamin C printed in the name, a pH range of 3.1 to 3.5 printed in the maker’s copy, a dispensed dose of 2 to 3 drops, a use window of three months from opening with the maker’s own advice to write the date on the bottle, and independent clinical panels printed at their sizes, 30 subjects graded by experts over four weeks, 31 measured instrumentally at one week, 34 self-assessing, the strongest panel record in the field, which is what the active row’s 17 buys. The charge is the two-list column’s headline: an earlier rendering of this bottle ran 25 items, with ergothioneine ninth, two peptides and a hyaluronate aboard, and the maker’s FAQ confirms the formula was streamlined, while American retail highlights go on selling the dropped ergothioneine by name. A buyer comparing documents meets two bottles; the desk grades the current 17 and prints the divergence. The booster format is a genuine fit distinction, drops mixed into a moisturizer or worn alone, twice daily, which the fit row credits. What the value row cannot credit is the arithmetic: $59 for two-thirds of an ounce is about $88.06 the ounce, nearly double the next dearest ounce in the field and nearly fifteen times the winner’s, for a list that recently lost a third of its cast. Documentation this good should not need a small bottle to pay for it.

La Roche-Posay Retinol B3 Serum
A retinol serum, 23 items on the published list, F.I.L. B244835/1: water, glycerin second, cyclohexasiloxane, alcohol denat. fourth, pentylene glycol, niacinamide sixth, dimethicone, soybean oil, the emulsifier, sodium hyaluronate tenth, retinol eleventh, adenosine twelfth, and the tail, retinyl palmitate twentieth, tocopherol twenty-first, phenoxyethanol, and Parfum twenty-third and last. Three findings govern the score, and all three are documentary. The dose: the maker’s European key-ingredient panel prints 0.3 percent retinol, pure plus time-release, while its American page prints the words and no number, so the bottle is dosed on one continent’s document and undosed on the other’s, the only split verdict in the field, graded here on the fuller record with the American silence charged. The scent: Parfum stands on the list, last and disclosed by the list itself, in a retinol sold by the pharmacy house whose name is a byword for sensitive skin, its retail record describing an allergy tested formula with fragrance, a phrase that contains its own argument. The alcohol stands fourth, ahead of the niacinamide sixth that gives the bottle its B3. Against the charges, the credits are real: a full coded list published entire, American directions that print a measured dose, 3 to 4 drops in the evening, and a clinical record of 51 women over two months carried in its European materials, the longest trial in the field, which the active row’s 15 reflects. The house’s wider record stands as evidence and is not transferred: its Dermallergo eye cream took third on Card No. 90 at 82 with a fragrance-free, preservative-free list, which proves the house can write the clean version of this document when the category asks. Here it did not, and 69 is the price of the difference.

The value table
Price per ounce against score, the arithmetic checkable. The shelf runs from $6.00 to $88.06 the ounce, a spread of nearly fifteen times, and its dearest ounce is ranked sixth: on this shelf, price buys bottle size, brand and copy, and the documentation lives at the cheap end.
| Serum | Score | Price per ounce | The verdict in one line |
|---|---|---|---|
| The Ordinary Niacinamide 10% + Zinc 1% | 89 | $6.00 | The full dose at both names, on the shelf’s shortest list, at its lowest price. |
| The Ordinary Hyaluronic Acid 2% + B5 | 79 | $9.90 | The water layer’s ounce: five forms of the acid summed in one printed figure. |
| Naturium Retinaldehyde Cream Serum 0.10% | 84 | $18.82 | The ladder’s ounce, in the field’s biggest bottle: the night active at a fair multiple. |
| Timeless 20% Vitamin C + E Ferulic Acid Serum | 81 | $27.95 | The trial’s ounce: about a month a bottle, by the maker’s own arithmetic. |
| CeraVe Skin Renewing Vitamin C Serum | 79 | $29.99 | The sealed tube’s ounce: a dosed C and a coded list at a pharmacy price. |
| La Roche-Posay Retinol B3 Serum | 69 | $44.99 | The fragranced retinol’s ounce: its dose printed on another continent. |
| Paula’s Choice C15 Brightening Super Booster | 75 | $88.06 | The ceiling ounce: the field’s best panels, in its smallest bottle. |
The skip stands outside this table’s ranking but not outside its arithmetic: the TruSkin prints $21.99 for a full ounce at its maker, a mid-table ounce between the Naturium’s and the Timeless’s, and it is printed in the verdict box above, because price was never its problem. Six of the eight bottles are a full ounce or better; the booster’s 0.67 fl oz and the eye shelf’s fractions are where this category’s margin usually lives, and here the small bottle is also the expensive one, which the table prints rather than tidies away.
Which one to buy
Most readers: The Ordinary Niacinamide 10% + Zinc 1%, $6.00 at Ulta. Both actives dosed, the shortest and fullest record in the field, no fragrance, worn morning and night, and the caveat carried on its card: its evidence is its document, not a panel, and at this price the document is enough.
The short list behind it: the Naturium (84) for the night brief, the only ladder here; the Timeless (81) for brightening with a trial printed behind it; the CeraVe tube (79) for the reader who wants vitamin C sealed and coded by the pharmacy school.
The water-layer reader: The Ordinary’s hyaluronic serum (79), $9.90 the ounce, under a moisturizer, bought as the support act it honestly is.
The booster reader: the Paula’s Choice (75) is bought for its panels, its printed pH and its drop count, with the streamlined list and the $88.06 ounce both printed on its card; go in with both numbers read.
The pharmacy loyalist: the La Roche-Posay (69) is a real retinol with the field’s longest trial behind it, and it is bought knowing its dose is printed in Europe, its alcohol stands fourth, and its Parfum stands last.
What we could not verify, and what we rested
The lists were graded as published, and their provenance varies, printed here rather than tidied away. The Paula’s Choice current list was read on the maker’s Singapore panel; its American FAQ confirms the streamlining in the maker’s own words, and American retail highlights still name the dropped ergothioneine. The La Roche-Posay list was read on the maker’s coded record as carried by its European retail; the maker’s American page prints its price, its 3 to 4 drop directions and its key ingredients, and no percentage. The CeraVe vitamin C was graded on the maker’s F.I.L. list as carried on its CVS panel; Target shelves the same tube at $23.99, and the card’s price stands on the door the desk opened. The Timeless current list was read on the maker’s UK store; its American page prints the price, the directions, the trial and the storage discipline. The hyaluronic serum’s panel reads 34 subjects on Sephora’s rendering and 32 on another retail rendering; the card grades 34 and prints the divergence here. The Naturium’s pill leads to Ulta’s Naturium serum shelf, the category page where the bottle and its $31.99 price stand; its exact product page is a November capture. The skip’s price stands on its maker’s store, with Target’s $24.99 shelf price printed in its verdict box. Prices were checked on 22 October 2026 against merchant pages carrying the exact products: the niacinamide serum and the Naturium shelf at Ulta, the Timeless, the booster and the retinol at their makers, the CeraVe tube at CVS, the hyaluronic serum at Sephora.
Rested, and why. CeraVe’s Resurfacing Retinol Serum is rested on the dose question and on bench balance: its maker publishes a full 33-item list, niacinamide fifth, its encapsulated retinol nineteenth, and no percentage anywhere, while a 0.3 percent figure circulates in third-party retail copy with no maker source behind it, and this desk does not grade numbers nobody signs; two retinoid bottles stand ranked here and this third waits. The Ordinary’s Retinal 0.2% Emulsion is rested on bench depth: its published list runs 32 items with retinal sixth, the highest retinoid position on the wider shortlist, and it is first in line for the follow-up Card. Mad Hippie’s Vitamin C Serum is rested unopened, a derivative-form vitamin C whose record the desk did not open for this Card. And H&M is rested, as it has been across the run: no product from its shelf is scored on this page. The photograph gap is admitted plainly: the bank holds no serum product photography, no bottle, dropper or bathroom-shelf frames, the grooming run’s standing gap, so these cards run text-first and the hero is the subject itself, the face in warm light. Product and shelf frames are wanted from the merchant programmes.
Questions, answered
What is the best face serum for men?
On the published record, The Ordinary Niacinamide 10% + Zinc 1% at 89 of 100: an 11-item list with niacinamide second and zinc PCA fourth, both doses printed in the product’s own name, fragrance-free, at $6.00 for a full ounce at Ulta. Naturium’s Retinaldehyde Cream Serum 0.10% is second at 84, the night bottle, its retinal dose printed in its name at the middle of a three-strength ladder. Behind them the shelf splits by species before it splits by quality: three vitamin C bottles at 81, 79 and 75, a hyaluronic layer at 79, and a fragranced retinol at 69, ranked last of the seven.
Do face serums actually print their doses?
On this shelf, mostly yes, and it is the grooming run’s contrast case. A printed percentage stands behind six of the eight bottles on the maker’s own record: niacinamide 10 percent with zinc 1 percent, retinaldehyde 0.10 percent, vitamin C at 20, 10 and 15 percent, and hyaluronic acid at 2 percent, that last a combined total across five forms of the acid. The seventh bottle, the La Roche-Posay retinol, prints its 0.3 percent in the maker’s European materials and withholds it from its American page. The eighth, the skip, names five headline actives and doses none of them. Set the shelf beside the eye shelf on Card No. 90, where one bottle in eight printed a dose, and the difference is the category: serums are sold on actives, so actives are what their makers measure in public.
Vitamin C, retinol, niacinamide, hyaluronic acid: which serum does what?
Four jobs, and this page grades them as one shelf with the species named on every card. Vitamin C is the morning antioxidant: brightening and tone, three bottles here at 20, 15 and 10 percent. The retinoids, retinol and its faster relative retinal, are the night shift: texture and fine lines, used a few nights a week at first, both bottles here printing evening directions or a weekly cap. Niacinamide is the regulator: tone, visible pores and oil, the one species here dosed for twice-daily wear. Hyaluronic acid is the water layer, a support act that holds moisture at the surface and seals nothing, worn under a moisturizer. A serum is not charged on this page for another species’ job: the water layer is not faulted for lacking a treatment active, and the retinoid is not credited for hydration.
Can you layer a vitamin C serum and a retinol?
The makers on this shelf print the working answer themselves. Paula’s Choice’s own guidance is that vitamin C pairs well with niacinamide and the exfoliating acids, with one named exception, copper peptides, which it tells readers to keep in a different half of the day. The bottles’ directions draw the same map: every vitamin C bottle here is a morning bottle, every retinoid here is an evening bottle with a stated frequency, the Naturium capped at three nights a week. Morning C, evening retinoid, moisturizer over both, sunscreen over the morning: that is the order the printed record supports, and no bottle on this page asks for the two species in the same layer.
How much serum is a dose?
Five of the eight bottles print a number. The Paula’s Choice booster dispenses 2 to 3 drops, the La Roche-Posay dropper 3 to 4 drops, the Timeless pump 1 to 2 pumps, with the maker’s own arithmetic that an ounce lasts about a month at that rate, and the Naturium and the skip 2 to 3 pumps each. Three print none: the two Ordinary bottles direct a few drops or whole-face application without a count, and the CeraVe vitamin C tube prints no dose at all. A printed count is a small thing until it is missing: it is the difference between a bottle that lasts the month its maker describes and a bottle emptied by instinct in a fortnight.
Why does one ounce of serum cost $6 and another $88?
Because nothing on the lists scales with the price, and this page prints the arithmetic. The cheapest ounce, the winner’s, is $6.00 and carries the shelf’s shortest list with both its actives dosed. The dearest, the Paula’s Choice booster at about $88.06 the ounce, carries a 17-item list streamlined from 25 under the same name and price. Between them, the retinal ladder’s ounce is $18.82 in a 1.7-ounce bottle, the Timeless ounce $27.95 with a third-party panel behind it, and the fragranced retinol’s ounce $44.99. What the spread buys, reading down the value table, is bottle size, brand and copy. It does not buy documentation: the winner costs $6.00 the ounce, and the hyaluronic serum level with fourth place costs $9.90.
Why was TruSkin sent home?
Because it is the one bottle here whose name is a list of actives and whose formula record doses none of them. The maker’s own page sells five headline ingredients, vitamin C as its SAP salt, retinol, niacinamide, hyaluronic acid and squalane, and prints a full 25-item list on which all five stand undosed, retinol seventh and niacinamide ninth, with a sixth active, salicylic acid, eleventh, also unmeasured, and a grapefruit peel oil twelfth that the maker’s texture copy calls a natural fragrance. A serum is the one category where the dose is the product, as the six dosed bottles above it prove. A five-active bottle with zero percentages is a label wearing a formula. Scored 42 and sent home.
The shelf above the sink continues at Card No. 66, moisturizers, Card No. 67, cleansers, Card No. 68, sunscreens and Card No. 90, eye creams; the routine that orders them is in the skincare Decoder; and the argument this Card makes about the dose a maker prints is continued in the Grooming Takes, most recently Take No. 12.
