The night shelf. Eight retinoid records judged on the documents they publish, with the one drug panel on the shelf printed beside the cosmetics' lists as the comparison they invite.

Checked and updated October 2026
The short version: Differin Gel, the shelf's one drug record, wins at 85 on the panel the law wrote, with The Ordinary Retinal 0.2% Emulsion at 82 and Medik8 Crystal Retinal 6 at 79 behind it. The counts the whole table rests on: a strength printed by the maker, in the name or on the maker's own product page, 5 of 8. No strength printed in the maker's American materials, 3 of 8. A full ingredient list on the maker's own site, 4 of 8, with the fifth complete list on the shelf filed as a Drug Facts panel. Fragrance filed as Parfum or Fragrance, 2 of 8. Ramp-up or tolerance directions printed, 7 of 8, and a complete week-by-week ladder, 1 of 8. Kiehl's Micro-Dose is sent home at 63: $65 an ounce, and its maker's page never prints the dose.
First, the decision
The default buy: Differin Gel, 85. The only record here whose strength, identity, directions and warnings were all written to a legal standard, at $13.49 the cheapest ticket on the page. It is an acne drug and is labelled as one; read its card before you buy it for any other job.
The cosmetic winner: The Ordinary Retinal 0.2% Emulsion, 82. The strength is the name, the list is published, and the borrowed claims are disclosed by the maker itself.
The ladder and the ramp: Medik8 Crystal Retinal 6, 79. A decoded rung number, a crystal system cashed in its own list, and the only complete ramp printed by any maker here, at the shelf's dearest rate.
The strongest printed dose: Paula's Choice CLINICAL 1% Retinol Treatment, 73. One percent in the name, a controlled-release claim, a printed ramp, and the joint-dearest rate on the shelf.
The drugstore serum, with its warning: CeraVe Resurfacing Retinol Serum, 70. A fair rate and a real support cast, in a bottle that never says how much retinoid it holds.
Sent home: Kiehl's Micro-Dose Anti-Aging Retinol Serum, 63. Sixty-five dollars for a dose described by an adjective. The full case is at the foot of the cards.
This shelf, in three findings
The panel the law wrote
One record on this shelf carries a Drug Facts panel, and it is the only document here the maker did not get to write in its own words. Differin's panel names the active ingredient, adapalene USP 0.1 percent, doses it on the face of the label, prints seven inactive ingredients behind it, and carries its tolerance language as a warning with legal weight. The seven cosmetics publish what they choose. Four of the seven print a full ingredient list on the maker's own site. Three print no strength anywhere in their American materials. The panel is printed beside their lists in the table below because the comparison is the one the shelf invites: every cosmetic here sells a molecule with a dose, and exactly one record on the page is required to state both.
The number is not always the dose
Medik8's Crystal Retinal 6 is 0.06 percent retinaldehyde. The 6 is a rung on a ladder, and the maker prints the percentage beside the rung on its own product page, all six rungs dosed and priced in its store, which is the honest way to run a confusing name. The rest of the shelf's numbering is worse. La Roche-Posay prints its 0.3 percent in its overseas materials and withholds it from its American page. CeraVe prints no percentage anywhere its American buyer can read. Kiehl's prints no number at all, only the word micro-dose, at $65 an ounce. A strength in the product's name counts as printed on this page, and five of eight records manage it in the name or on the maker's own product page. The other three ask to be bought on trust.
The ramp is the instruction this shelf owes
A retinoid is the one cosmetic a buyer can get wrong on the first night, so the directions are part of the document, and they are graded. Seven of eight makers print a ramp-up or tolerance instruction. One prints the whole schedule: Medik8, twice a week for two weeks, every other night for two weeks, then nightly. The Ordinary prints a weekly start, Paula's Choice a start of one or two nights a week, Neutrogena a phase-in with a not-for-beginners warning, and Differin's panel carries its tolerance language as a drug warning. The one maker that prints no ramp is Kiehl's, whose answer is that none is needed, daily use from day 1, on a dose it does not state.
How the scores work
Each card is scored out of 100 on five rows. Specification & claim honesty (30) grades whether the maker names the molecule it sells and prints the strength it doses; a percentage in the product's name counts as printed, and a proprietary name or a dose adjective standing where a number belongs is graded as the weaker document. Ingredient & panel record (20) grades the list as published: the retinoid's seat in it, the delivery system claimed in copy and cashed or not cashed in the list, and the fragrance filed as one word or absent. Fit & format (20) grades the format the document describes and the directions the maker prints, the ramp counted as the instruction this shelf owes its buyers. Value (15) grades the checked price per ounce against the record it buys. Longevity & service (15) grades the stability of the record itself and any service term the maker prints. The shelf's one drug record is graded as the drug document it is, and the cosmetics beside it are graded on their own documents, never on the panel they do not carry. Scores grade documents, not faces. No bottle here was applied or worn, and that discipline is printed again in the honesty section below.
Differin Gel (Adapalene 0.1%)
Start with the document, because on this shelf the document is the story. Differin is an over-the-counter drug, and its label is a Drug Facts panel filed under federal rules, hosted by the maker as the FDA label itself. The active ingredient is named and dosed on the face of the panel, adapalene USP 0.1 percent, a retinoid, and the inactive ingredients are printed behind it, seven of them: carbomer 940, edetate disodium, methylparaben, poloxamer 182, propylene glycol, purified water and sodium hydroxide, with a further note that hydrochloric acid may be present to adjust pH. There is nothing else in the tube to hide behind. The directions are the most legally complete on the shelf: adults and children 12 and older, use once daily, clean the skin gently and pat dry before applying, cover the entire affected area with a thin layer, and do not use more than one time a day, because applying more will not provide faster or better results and may worsen irritation. The tolerance language is printed as a warning, not a tip: irritation is more likely in the first few weeks, the acne may appear to worsen before it improves, and the stop-use lines are printed too, stop and ask a doctor if irritation becomes severe, or if no improvement shows after three months of once-daily use. The pregnancy line is printed on the panel, ask a doctor before use if pregnant or breast-feeding, with a stop-use line for anyone who becomes pregnant while using it. The pea-sized amount stands in the maker's own routine copy rather than on the panel, and that copy allows the application morning or evening, but not both. Two honest limits frame the win. The panel's claims are acne claims; the law cleared this molecule for breakouts, the document never promises a wrinkle result, and a buyer shopping for lines is reading a document written for a different job, which is why the fit row is this card's lowest and why the record is seated and labelled as the shelf's drug entry rather than dressed as a serum. And the maker does not sell it direct, so the record stands on the filed label and the merchant shelf. Judged on the paper it publishes, nothing cosmetic here is close: the one complete document on the shelf, at the cheapest ticket on the page.

The Ordinary Retinal 0.2% Emulsion
The strongest naming on the shelf: the strength is the product's name, 0.2 percent, and the molecule is named beside it in the maker's own description, stabilized retinaldehyde, the retinoid one conversion step from the active form where retinol takes two. The list, as the maker's merchant channels carry it identically, runs 32 entries with retinal sixth, hydroxyapatite the entry directly ahead of it, and no Parfum or Fragrance entry anywhere in it. The directions print a real start with a printed ceiling: a pea-sized amount in the evening on dry skin, begin with a weekly application and gradually increase to twice a week, a few days apart, as tolerated, keep away from the eye contour, do not use with other retinoid products, and use sun protection during the day. One finding costs the honesty row its top marks, and the maker discloses it in its own materials: the claims printed for this bottle were measured on the Retinal 0.1 percent emulsion that came before it, in a study of 30 volunteers, so the claims on the 0.2 percent bottle rest on its weaker sibling's evidence. Disclosure is the honest way to carry that fact, and it is graded better than silence, but the claims are borrowed and the card says so. The format is the other limit: 15 millilitres is half the standard ounce, so the shelf's cheapest serum ticket, $14.90 at Sephora and at the maker's own store alike, runs at about $30 an ounce, mid-pack by rate. A complete, candid document in a small tube.

Medik8 Crystal Retinal 6
The number in this name is not the dose, and the maker is the one who says so. Crystal Retinal 6 carries 0.06 percent retinaldehyde; the 6 is a rung, and the maker's American page prints the percentage beside the rung and the whole ladder beside that: Crystal Retinal 1 at 0.01 percent for sensitive skin, 3 at 0.03 for new users, 6 at 0.06 for regular vitamin A users, 10 at 0.1, 20 at 0.2 and 24 at 0.24 for experts only, every rung 30 millilitres and every rung priced in the maker's store, from $56 at the first to $137 at the last. Graded here is rung 6. The American list runs 41 entries with retinal 22nd, deep in the formula's second half, and the delivery system is cashed inside it: cyclodextrin stands seventh, the carrier the maker's own science pages name for the crystal encapsulation, and carrot seed oil, the base of the maker's patented stability complex, stands 21st, directly ahead of the retinal. The maker's pages describe the system plainly, retinaldehyde encased in a crystal-shaped vehicle that time-releases it, the complex reinforcing it, and an airless, aluminium-lined tube enclosing it. Two entries temper the fragrance story: no Parfum entry is filed and the page claims no artificial fragrance, but coumarin, a fragrance allergen, stands 39th, in the company of vanilla and tonka bean extracts at the list's foot. What lifts the card is the directions, the shelf's only complete ramp, printed by the maker: two pumps in the evening after cleansing, twice a week for the first two weeks, every other night for the next two weeks, then every night, moisturizer after, sunscreen the next morning, and at least one full tube finished at a strength before climbing the ladder. What holds the score is the rate: $87 an ounce at Sephora and at the maker is the dearest document on this shelf by a wide margin.

Paula's Choice CLINICAL 1% Retinol Treatment
The highest dose anyone on this shelf prints: 1 percent retinol, in the name. The list is published by the maker in full, 53 entries with retinol 17th and no Parfum entry, and the delivery claim printed in the maker's own description is controlled-release, a claim no entry in the list cashes in a form a reader can point to. The cast is a peptide and vitamin C story: a vitamin C ester, tetrahexyldecyl ascorbate, stands ahead of the retinol at 13th, three palmitoyl peptides stand directly behind it, ceramide NG with them, and the oat extract the soothing copy leans on stands deep in the list, at about 25th, not at its head. The directions respect the dose: a pea-sized amount, no more than three evenings a week at first, then every other night, then every evening as tolerated, with the lips and the corners of the eyes kept clear. What holds the card is the price and the seat. At $65 list for one ounce it is the joint-dearest ticket here, and a buyer at the top rate is buying a retinol seated 17th in a long list, behind the silicones, the emulsifiers and the vitamin C ester, on the strength of the number in the name. That number is real, printed, and the shelf's highest, and the maker's own FAQ reaches further, comparing the 1 percent to a prescription retinoid, which is printed here as the maker's comparison and graded as copy. The document behind the number is thinner than the number suggests.

CeraVe Resurfacing Retinol Serum
The molecule is named and the dose is not, anywhere. CeraVe's page sells encapsulated retinol and prints no percentage on the product page, in the name, or anywhere else in the maker's American materials; the figure that circulates for this serum in third-party writing stands in no maker document this desk could read, and it is not printed here. What the maker does publish is the full list, 33 entries, and the list is the finding: retinol stands 19th, with no retinyl ester beside it anywhere in the formula, behind niacinamide at fifth and plain alcohol at 24th, with no Parfum entry filed and three ceramides and licorice extract seated as the copy claims. The encapsulation the copy claims is identified with no entry in that list; the maker's page names no capsule ingredient, and its one slow-release sentence, written for its MVE technology, is about its ceramides, not its retinol. A second list circulates for this serum in merchant channels, seating retinol 29th with a retinyl propionate ester 30th; the maker's own American page prints neither the ester nor that seat, and this card grades the maker's page. The directions are tolerance-gated and nothing more: apply evenly to the face daily, PM only, space the applications out until skin adjusts if discomfort occurs, and apply a sunscreen while using it; no week-by-week schedule is printed. An eight-week consumer study of 50 is cited by the maker. The rate is the friendliest on the shelf after the drug itself: $16.49 an ounce at Target, $21.99 on the maker's own page. The document is what fails: a retinoid serum that will not say how much retinoid is in it.

La Roche-Posay Retinol B3 Serum
Scored 69 on Card No. 91, where it stood in a mixed serum field; re-graded here on the retinol shelf's basis, it falls one point to 68, and both numbers stand on this card because that is the house rule for a second grading. The American document is the thinner of the maker's two records. The United States page prints no percentage and no ingredient list at all, only key ingredients: pure retinol, gradual release retinol, niacinamide. The dose exists, but the maker prints it on another continent: 0.3 percent stands in La Roche-Posay's overseas materials, beside the full coded list, F.I.L. B244835/1, where retinol stands 11th of 22, the gradual release resolves into retinyl palmitate at 19th, alcohol denat. stands fourth, and Parfum stands 22nd and last, one of only two fragranced lists on this shelf. A trial of 51 women over two months stands in the overseas materials too. The ramp is genuinely printed, on the American page itself: its own FAQ instructs the buyer to introduce retinol gradually, starting at two or three times a week and increasing the frequency as tolerance builds, toward every other night or every night, with three to four drops in the evening as the stated dose. What the re-grade weighs is the split itself: an American buyer at $44.99 an ounce meets a page that withholds the figure and the list the same maker publishes for overseas readers, and the word gradual in gradual release does the work a number does elsewhere on this shelf.

Neutrogena Rapid Wrinkle Repair Retinol Pro+ 0.5% Power Serum
The claim is strong and the paper trail is the weakest here, and both facts are printed. The name carries the dose, 0.5 percent pure retinol, the maker's highest strength concentration, and the directions are candid: four or five drops every evening, recommended for retinol users and not beginners, gradually phase into the routine and work up to nightly as tolerated, with a daytime SPF 30 instruction and a reduce-frequency warning if the effects persist. The list is 12 items and water-free, retinol seventh and Fragrance eighth, seated directly behind the active it perfumes, in a formula sold on powerful results with less irritation. The limit is provenance. The maker's own product page on neutrogena.com could not be located or opened for this card, so this record is graded on the maker's syndicated product document as carried by its merchant channels, the same copy standing at Ulta and at CVS, printed here in the open rather than tidied into a maker-page citation. Merchant copy also carries a rebranded twin for this serum, Visible Repair, described as fragrance-free, which the graded list, with Fragrance eighth, contradicts; which document is current could not be settled from maker sources. That document also contradicts itself once: an answer in its own FAQ describes a 1.7 fluid ounce jar for a product sold as a 1.0 ounce serum, left uncorrected in the maker's copy and noted here. The sibling cream on the same line sells its system under a proprietary name, Accelerated Retinol SA, the SA standing for sustained action in the maker's own explanation, which is the naming habit this shelf grades down wherever it stands. At $42.99 an ounce at the verified door below, with the document borrowed and the fragrance filed behind the retinol, a strong claim lands mid-table.

Which one to buy
Breakouts, on the record: Differin (85). The drug, bought for the job its panel describes, at the shelf's lowest ticket.
Starting a retinoid: Medik8 Crystal Retinal 6 (79) for the printed ladder, with rungs 1 and 3 below it if the document's caution persuades you to start lower; The Ordinary (82) if the budget decides, on a weekly start.
Experienced, dose stated: Paula's Choice (73) at a printed 1 percent, or Neutrogena Pro+ (66) at a printed 0.5, bought knowing its document is a syndicated one.
Post-acne marks on a drugstore budget: CeraVe (70), bought with its card read: the support cast is seated, the dose is unstated, and the retinol sits in the list's second half.
Sensitive skin, fragrance discipline: the lists that file no Parfum or Fragrance entry are Differin, The Ordinary, Paula's Choice, CeraVe and Kiehl's; of those, the first three also print their doses. Medik8 files no fragrance entry either, but its list carries coumarin, a fragrance allergen, at 39th.
La Roche-Posay Retinol B3 (68): a real dose and a real ramp, published for overseas readers. Buy it where the tube can be read, and know the American page will not show you either.
How this page was made, and what it rests on
Every score on this page rests on the maker's own published evidence, the filed FDA label record for the shelf's drug entry, and the merchant shelf, read on October 22, 2026, with every merchant door opened and priced the same day. Where a maker's document could not be read in its primary form, the card says so and grades what stands instead: Neutrogena's own product page could not be located, so its record stands on the maker's syndicated document as carried by Ulta and CVS; Kiehl's product page prints no ingredient list, so its list stands on Ulta's rendering of the maker's list, counted entry by entry; Paula's Choice's full list and ramp were read on the maker's own European page after the American page returned its FAQ and its offer without the list; La Roche-Posay's American page prints no list and no dose, so its record stands on the maker's overseas materials, cited as such wherever they are used.
Three records stand in more than one version, and the versions are printed rather than smoothed over. CeraVe's maker's page prints a 33-entry list with retinol 19th and no ester, while a second list seating retinol 29th with a retinyl propionate ester 30th circulates in merchant channels; the card grades the maker's page. Medik8's maker pages carry more than one list for the graded rung; the card grades the American product page's, 41 entries with retinal 22nd. The Ordinary's list is graded as its merchant channels carry it, identical at Sephora, Boots and Olive Young, after the maker page's ingredients section did not return in extraction. Kiehl's 0.1 percent figure stands only in merchant-carried panels and is reported as a merchant figure, never as the maker's.
No application or wear testing was done for this page. Nothing here was applied, worn or washed off. Irritation, peeling, purging and results are graded only where a document makes a claim about them, and graded as claims. The ramp schedules quoted are the makers' printed instructions, not this page's prescriptions. Prices are the checked shelf prices of October 22, 2026 and will move.
The neighbouring records stand where they were graded. Card No. 91's field was mixed serums: its winner, The Ordinary Niacinamide 10% + Zinc 1% (89), is not a retinoid and is not re-graded here, and Naturium's retinaldehyde cream serum (84) keeps its grade on that shelf. The one product graded on both shelves is La Roche-Posay Retinol B3, and its two numbers are printed wherever it appears: 69 there, and 68 here. The morning after this shelf is Card No. 109's: every maker here instructs sunscreen by day, and the SPF moisturizers graded there carry the panels this page's night records point to.
Questions, answered from the record
How is this shelf different from Card No. 91?
Card No. 91 graded a mixed serum field, and The Ordinary's niacinamide serum won it at 89. This shelf seats only retinoid records and grades one question first: does the maker name the molecule and print its strength. La Roche-Posay Retinol B3 stood on both shelves; it scored 69 there and is re-graded 68 here on this shelf's basis, with both numbers printed on its card. Naturium's retinaldehyde cream serum, 84 on Card No. 91, keeps its grade on that shelf and is not seated here.
Why does a drug win a serum ranking?
Because this page grades documents, and Differin's document is the only one on the shelf written to a legal standard. Its Drug Facts panel names the active, doses it at 0.1 percent, prints its seven inactive ingredients, and carries its directions and warnings in a fixed format the maker cannot edit for tone. The cosmetics beside it publish what they choose: four of the seven print a full list on the maker's own site, and three print no strength in their American materials at all. The win is labelled for what it is: Differin is an acne drug, its panel promises acne results, and it is seated here as the shelf's drug record, the comparison the cosmetics invite by selling a molecule with a dose.
Is 1 percent retinol stronger than 0.2 percent retinal?
The percentages are not one scale, because the molecules are not the same molecule. Retinol converts in the skin in two steps, to retinal and then to the active form; retinal is one step away, which is why a 0.2 percent retinal and a 1 percent retinol cannot be ranked by their numbers alone, and why this page grades the printing of the number rather than its size. What can be compared is the document: Paula's Choice prints its 1 percent in the name, The Ordinary prints its 0.2 in the name, and Medik8 prints its 0.06 on its own product page, under a rung number that is not the dose.
Which of these should a beginner buy, and which should an experienced user buy?
From the documents, since nothing here was worn. The beginner's document is Medik8's: the only complete printed ramp on the shelf, twice a week for two weeks, alternate nights for two more, then nightly, with rungs below the graded one at 0.01 and 0.03 percent for a slower start. The Ordinary prints a weekly start and the shelf's lowest cosmetic ticket at $14.90. The experienced user's documents are the two that say so themselves: Paula's Choice at a printed 1 percent, and Neutrogena, whose own directions read recommended for retinol users and not beginners. Differin is the acne record: buy it for breakouts, on its panel's terms.
Why was Kiehl's sent home?
Because at $65 an ounce, joint-dearest on the shelf, its maker's page prints no dose at all. The whole specification is the phrase micro-dose; the 0.1 percent figure attached to this serum stands in merchant-carried panels, not on kiehls.com. Its list, carried by retail partners, is complete and fragrance-free, and its directions print daily use from day 1 in place of a ramp. A buyer is asked to take the strength on faith at the top price, and this page does not grade faith above print.
Did you apply or wear any of these products?
No. Nothing on this page was applied, worn or washed off, and no score rests on a wear claim. Every number grades published documents: the maker's page and guide, the filed Drug Facts panel, the syndicated merchant document where a maker's own page could not be read, and the merchant shelf, all read on October 22, 2026. Where a claim exists only in copy, the card grades it as copy.
Next on the shelf: Card No. 91, Best Face Serums for Men, Card No. 109, Best SPF Moisturizers for Men, and Card No. 66, Best Moisturizers for Men. The routine these records sit inside: the skincare routine.
