The face at the sink, which is where every number on this shelf is finally spent, for hours or for seconds depending on the class of the bottle: the exfoliator ranking's own hero, standing at the head of a Take argued from that Card and the mask Card. The frame shows a wearer, not a bottle: the photo bank holds no exfoliant, peel or masque product photography, a gap both rankings name on their own pages and the honesty section below admits in full.
Checked and updated October 2026
The thesis, up front: the acid shelf is the shelf this column has been asking the others to become. On the exfoliator ranking, a headline active carries a printed percentage on four of eight records and a pH is printed on three, counts no earlier shelf in the run has approached. And the number still does not mean the same thing twice, because a dose is a strength multiplied by a contact time, and the shelf prints the first term across classes whose contact runs from all day to thirty seconds. The four dosed records are the three leave-ons and the one timed peel. The rinse-off acid cleansers carry the acid’s name with no number at all, salicylic acid sixteenth of 27 on one, two acids eleventh and thirteenth on the other. The shelf’s strongest bottle, a 30 percent acid total, is rationed by its own maker to ten minutes, twice a week, in print: the maker conceding, on his own label, that the number by itself is not the dose. This Take argues that a percentage is read with its clock or it is not read at all, that the rinse is not a footnote to the dose but half of it, and that the class column, not the strength column, is where this shelf’s honesty is decided. It is Take No. 8’s arithmetic carried onto the one shelf that prints enough numbers for the arithmetic to bind.
In this issue
The thesis: the rinse is not the dose
This column’s census has a usual shape: the number is missing, and the issue counts the bottles that print it. The body shelf printed one dose in eight, under legal compulsion. The cleanser shelf, two shelves further back, printed its strengths only where a drug panel compelled them and its contact times almost nowhere. The acid shelf breaks the pattern, and the break is what this issue is for. Here the numbers stand in the open: 2 percent in a winner’s name, 7 percent in a toner’s, 30 percent on a peel, a pH printed beside three of them, full lists on eight of eight. A reader who stopped at the dose column would call this shelf the run’s solved problem. The dose column is real, and this Take does not diminish it. It asks what the numbers buy, and the answer is in the column beside it, the one the Card prints in every card’s tag: the class. Three of the eight records are leave-ons. One is a timed rinse-off. Four are rinse-offs. And the numbers are not distributed across those classes the way a buyer reading a search result would assume. They are stacked, in order, at the long-contact end of the shelf, and they thin exactly as the water gets closer.
Start with the pairing the shelf itself offers, because it is cleaner than any pairing a brief could invent. The same house, The Ordinary, sells two of the three records at the shelf’s head. One is a glycolic toner at 7 percent, a leave-on, applied once a day in the evening and left: its number works for hours, and its record is graded second at 85. The other is a peeling solution at a 30 percent acid total, and its directions carry the strictest print on the shelf: no more than ten minutes, no more than twice a week, experienced users only. The strong bottle is the rationed bottle. If strength were the dose, the 30 percent record would be four times the 7 percent record and the conversation would end there. The maker’s own caps say otherwise, in the maker’s own typeface: the big number is permitted because its minutes are few, and it is graded third at 82, below the weaker leave-on it outweighs four to one on paper. The desk did not import this arithmetic into the shelf. It found the arithmetic printed on the shelf, in caps and ceilings, by the house with the most to gain from the numbers being read naively. A maker who rations his strongest number by the clock has already ruled on the question this Take exists to ask. The rinse, and its timed cousin the peel’s ten minutes, are not the dose’s packaging. They are its second term.
Now walk to the other end of the shelf, where the water is, and watch the number change its behaviour. The CeraVe Renewing SA Cleanser is the Card’s designated rinse-off record, seated in print as a class of one, and its name carries the acid the shelf is named for: SA, salicylic acid. On its 27-item list the acid stands sixteenth, behind niacinamide at fifth and gluconolactone at sixth, and it is dosed nowhere. The Neutrogena sent home at 44 carries two acids, glycolic at eleventh and lactic at thirteenth, both undosed, with Fragrance standing between them and the hyaluronic acid of its line’s name standing last of seventeen. The two physical scrubs dose by particle and pressure, pumice second of 23 on the Brickell, walnut shell second of 24 on the St. Ives, and the one duration printed anywhere in the rinse-off class is the Brickell’s thirty-second massage. So the shelf’s map, read whole, is a gradient: where the product stays, the number is printed; where the product is timed, the number is printed and capped; where the product is washed off in under a minute, the number is gone and the name does the work alone. The buyer comparing across the gradient with the numbers in front of him is comparing three different kinds of statement as if they were one: a strength with hours behind it, a strength with ten minutes behind it, and a name with nothing behind it. The typeface does not tell him which is which. The class does, and the class is printed smaller.
The mask shelf, graded a fortnight of production later on Verdict Card No. 95, supplies the proof case and its limit in the same field. Its winner, The Ordinary’s Salicylic Acid 2% Masque at 92, the highest score the grooming run has printed, is a rinse-off that carries both terms: the 2 percent in its name, its pH printed at 3.50 to 4.50, and a ceiling of no more than ten minutes on dry skin standing in its directions. A timed product can print its clock; the masque is the existence proof, and it was graded first in its field partly on that record. Beside it, the Origins mask doses both its headlines in copy, charcoal at 1 percent and clay at 18 percent, and prints no minutes at all, fully dry being the whole of its timing, charged on its fit row. Seven of the eight mask records print a wear time; one prints a dose without one. The two Cards together describe a shelf learning the lesson unevenly: the numbers arrived first, the clocks are arriving second, and the records that print both are the records at the top of both rankings. That is not a coincidence the desk is willing to read past. It is the standard, already standing on the shelf, waiting to be required of the rest of it.
Nothing on this page is scored. Every score quoted here, every row, every price and every count is the exfoliator ranking’s or the mask ranking’s, Verdict Card No. 93 and Verdict Card No. 95, reproduced exactly as those Cards published them: Paula’s Choice 2% BHA at 88, The Ordinary Glycolic 7% at 85, The Ordinary’s peeling solution at 82, the CeraVe Renewing SA Cleanser at 76, Jack Black Bump Fix at 73, the Brickell scrub at 62, the St. Ives scrub at 52, and the Neutrogena Hydro Boost Exfoliating Cleanser sent home at 44; and on the mask Card, The Ordinary’s salicylic masque at 92 and the Origins at 82. The only arithmetic of this page’s own is counting what the two records print: how many strengths stand, how many clocks stand beside them, and which classes the two columns fall in. One pairing in this issue’s own brief, a 2 percent acid left on set against a 2 percent acid rinsed off in sixty seconds, did not survive those records, and the correction is confessed in the honesty section, in words, because a column about grading numbers should print its own corrections where its readers can find them.
The record, counted
Start with the dose column, because its fullness is the argument’s foundation exactly as the body shelf’s list column was the last issue’s. A headline active with a printed percentage: four of eight records. A printed pH: three of eight, the winner’s 3.2 to 3.8, the glycolic toner’s approximately 3.6 with the maker’s pKa note beside it, the peel’s 3.5 to 3.7. Full ingredient lists published: eight of eight, the Brickell publishing two. Frequency guidance printed: seven of eight, the Brickell’s captured directions printing a massage and a rinse and no weekly count. A Fragrance entry: two of eight, the St. Ives’s nineteenth of 24 and the skip’s twelfth of 17. Against the run’s earlier censuses these are rich numbers, and they are printed here as the credit they are: this is the shelf whose makers have done most of what this column asks. The census this issue adds is not of the numbers. It is of the numbers’ addresses, class by class, and the classes are the Card’s own, drawn in its TLDR, its species paragraph and its contact column.
The leave-on class first, three records, and the dose column is complete inside it. The winner’s 2 percent stands in its name, salicylic acid fourth of nine, pH printed, directions building from every other day to once or twice daily with the rinse expressly refused. The glycolic toner’s 7 percent stands second of 42, pH printed with an explanation, once daily in the evening. The Bump Fix is a drug, its 2 percent standing on the federal panel the law provides, its lactic acid named in the maker’s key ingredients and undosed, a partial record printed as partial. Three records, three printed strengths, contact measured in hours, and the numbers mean what a buyer thinks they mean, because the products stay where they are put. Whatever else this Take argues, it does not argue with this class: the leave-on shelf is the run’s model of a printed dose, and its two leaders are graded first and second on the Card for records that include exactly this completeness.
The timed class is one record on the exfoliator Card, and it is the census’s pivot. The peeling solution prints the shelf’s largest strength, a 30 percent acid total across four acids with salicylic acid at 2 percent eighth of 24, its pH at 3.5 to 3.7, and then it prints the terms on which the strength may be used: ten minutes at most, twice a week at most, experienced users. No other record on either acid Card rations itself this completely, and no other record needs to, which is the point the record section exists to make: the rationing scales with the number. On the mask Card the timed class is the whole shelf, and its counts run the same way in miniature: a wear time printed on seven of eight, the winner printing its ceiling beside its dose, the runner-up printing its doses, 1 percent charcoal and 18 percent clay, with no minutes at all. Two Cards, and in both of them the fullest records are the ones where strength and clock stand on the same page of the same document. Where only one stands, something in the grading charges for the missing term, a fit row on the Origins, a longevity row on the peel. The desks’ rows already price the second term. The typeface has not caught up.
The rinse-off class closes the count: four records on the exfoliator Card, and its dose column is empty in a specific and instructive way. Its two acid cleansers are undosed, the CeraVe’s salicylic acid sixteenth of 27 and the skip’s two acids eleventh and thirteenth of 17, and neither prints a contact time, so the class offers the buyer neither term of the dose it advertises by name. Its two scrubs are dosed by a different physics, particle and pressure, and print the class’s only duration between them, the Brickell’s thirty seconds, with no weekly frequency captured beside it; the St. Ives prints its frequency, three to four times a week, and carries no acid at all, its walnut shell second and its named apricot extract twenty-third. Read the three classes as one table and the gradient is the finding: leave-ons, three strengths in three records; the timed peel, one strength under three printed caps; rinse-offs, no strength and one duration in four records. The numbers did not fail randomly across this shelf. They failed downhill, toward the water, in the exact order of the contact they would have had to describe. A column that has spent fourteen issues counting missing numbers is bound to notice the first shelf where the numbers are present and sorted by class, because a sorted absence is a policy, and a policy can be argued with in a way an oversight cannot.
What the unqualified number costs
The first cost is comparison, and this shelf puts a price on it to the cent. The winner and the peel stand within a quarter of each other per ounce, $9.25 for the Paula’s Choice leave-on and $9.50 for The Ordinary’s peeling solution, and a buyer reading the two records side by side, as a search result or a shelf presents them, sees two dosed acids at one price point, one at 2 percent and one at 30. The fifteen-fold strength gap is the visible fact. The invisible fact is that the 2 percent is bought for hours of daily contact and the 30 percent for ten minutes twice a week, so the weekly contact the dearer per-minute record delivers is a small fraction of the cheaper one’s, and the comparison the numbers invite is not merely imprecise but inverted. Per ounce prices volume. Nothing on either record prices time, because time is the term the typography leaves at home. A shelf where the strength column is complete and the clock column is a directions paragraph is a shelf where the most dramatic number in the field, thirty, is doing marketing work its own maker’s caps contradict three lines later on the same page.
The second cost is escalation, and the rinse-off class prints the staircase’s lower steps in their mildest form yet. The first step is the name without the number: an acid carried in a product’s name or its line’s name, Renewing SA, Hydro Boost Exfoliating, standing undosed in the list’s second half, charged on the CeraVe only as a thin active record and on the Neutrogena as a sending-home, because on the CeraVe the wash itself is honest and the acid is furniture, while on the skip the acids are the pitch. The second step is the borrowed figure: the number from the leave-on class read across the aisle, a buyer assuming the cleanser’s acid works at the toner’s strength because the shelf taught him strengths are what acids have. No maker on this shelf prints that borrowing in words. None has to. The gradient does it, by putting the dosed and the undosed in one ranked list, in one typeface, under one shelf name, and letting the completeness of the head of the list lend its authority to the tail. The third step, the asserted ingredient standing in no list, is not on this shelf at all, and this Take says so plainly: the acid shelf’s failing is not invention, it is qualification withheld, which is a smaller failing and a more instructive one, because it is committed by the run’s best-documented shelf, in the open, by makers who print pH values for pleasure.
The third cost is paid by the honest records, and the ranking order prints it. The peel’s maker prints the fullest qualification on the shelf, strength, pH and three caps, and the record stands third, below two leave-ons whose numbers need no qualification because their class supplies it. The masque’s maker prints dose and ceiling together and stands first on his Card, which proves the qualification is not a commercial handicap where the class is understood to be timed. But on the exfoliator shelf the buyer’s eye, trained by every other shelf in the bathroom to hunt the percentage, meets 30 before it meets ten minutes, and the maker who printed both is read as the maker with the stronger product and the weaker nerve. Candour about time is taxed wherever the audience has been taught that strength is the whole dose, and the tax is paid in the only currency this desk deals in, rank read quickly. The antidote stands on the same two Cards, and it is the same antidote the last issue found on the body shelf in legal form: a record where both terms are printed and the product wins anyway, the masque at 92, the run’s highest grooming score, its ceiling printed in its own directions. Qualification is not what costs a record its rank. On the fullest shelf in the run, qualification is what the top of the ranking is made of.
The other side, stated fairly
The case against this Take is a serious one, and it runs in three parts. First: rinse-off acids are formulated for their contact, and everyone in the trade knows it. A cleanser’s acid works inside a surfactant system, at a strength and a pH chosen for a short exposure, and its maker’s silence about the percentage is not a withheld qualification but a correct judgment that the figure would be read against leave-ons it was never meant to match. The CeraVe’s own card makes the point: its salicylic acid stands sixteenth, behind a niacinamide and a gluconolactone, a supporting entry in a wash whose job is cleansing, and to demand its dose is to demand a number for an ingredient that is not the product’s instrument. The Card itself polices the classes, grading by contact column and species, so the buyer this site serves is already protected, and a Take that asks the shelf’s typography to repeat the Card’s work is asking labels to become essays. Second: contact is already priced. The peel costs $9.50 an ounce against the leave-on’s $9.25 precisely because a timed concentrate is a different economy, a bottle lasting months of twice-weekly minutes, and the value rows on both Cards grade per ounce with the class in view; the buyer is not charged leave-on money for rinse-off goods, and the market, not the label, has done the qualifying. Third: the buyer cannot run a laboratory at the sink. He cannot verify a pH, time a contact to the second across a real routine, or convert a percentage and a duration into a delivered dose with any honesty; the figures this Take wants printed in every class would be spent as vibes, compared naively across classes by exactly the readers least equipped to qualify them, and a shelf that prints a strength alone at least confines the naivety to one term instead of two.
Each part is true about something, and the record answers each on its own ground. To the formulation defence: conceded that a rinse-off is built for its contact, and refused as a defence of the name. This desk has never asked a cleanser to match a leave-on, and the Card this Take argues from grades the CeraVe as the shelf’s rinse-off record at 76, a respectable grade for an honest wash. What is charged is narrower: the acid stands in the product’s name, SA, and in the shelf’s name, exfoliating, and a name is a claim about what the product is for. If the acid is furniture, the name is decoration wearing an instrument’s clothes; if it is an instrument, its dose is a fair question, and on the record it is dosed nowhere. The maker cannot have the name’s authority and the furniture’s exemption in the same bottle. And the strongest answer stands on the maker’s side of the counter: where a house judges the acid to be the instrument, in the peel and the masque, it prints the dose and its clock without being compelled, which is the trade’s own verdict that the figures are printable when the product is serious. The silence downhill is not a formulation judgment. It is the same judgment, run in reverse, about how serious the claim needs to be.
To the pricing limb: the per-ounce figures are the Card’s, printed with their doors, and they price what the counter says they price, volume, and the counter’s own example gives the game away. A concentrate lasting months of minutes is an economy of time, and time is the term this Take says the number omits; that the market has quietly priced contact into the peel’s ounce while printing nothing about contact on its label is the finding restated as a defence. The buyer is owed the term in the document, not in an inference from a price he cannot decompose. The value row, meanwhile, grades the ounce because the ounce is what is sold; it has never claimed to grade the dose, and a reader who divides $9.50 by 30 percent and $9.25 by 2 percent in his head at the shelf is doing arithmetic the records invite and nothing corrects. Print the minutes beside the strength and the arithmetic corrects itself.
To the laboratory: the buyer is not asked to measure anything, and this column has never asked him to. He is asked to read the class before the number, a literacy of one word, leave-on, timed, rinse-off, and the Cards already print that word in every card’s tag because the desk judged it the minimum a buyer needs. The pH is a maker’s figure to print or withhold, and three of eight print it, which settles whether it can be done. As for the naive comparison the counter fears, it is not a risk the printing would create; it is the shelf’s current condition. The numbers already stand in one typeface across the classes, already compared by every reader who meets them in a ranked list or a search snippet, and the qualification is the only part missing. A reader who compares 30 against 2 today does so with nothing to stop him; a reader who meets 30 beside ten minutes, twice a week, has been stopped, by the maker, in print. The counter’s reader, unequipped and hurried, is precisely the reader the caps were written for. The desk’s position is the peel’s maker’s position: print both terms and trust the hurried reader with the whole fact, rather than protecting him from the second half of it.
The Take Rule
Read the class before the number; a percentage is a strength, and it becomes a dose only when its minutes stand beside it. On this shelf strengths stand on four of eight records and pH on three, the dosed numbers cluster where the contact is long, the shelf’s strongest bottle is rationed by its maker to ten minutes, and the rinse-off acids carry the name without the number, so buy the leave-on on its printed strength, the timed record on its printed caps, the rinse-off on its list and its price, and let the first shelf that prints both terms in every class set the standard every strength is graded against.
The picks, as published on the Cards
| Item | The record | Price, as published |
|---|---|---|
| Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant | The winner, 88: leave-on, the 2 percent dose in its name, salicylic acid fourth of nine, pH 3.2 to 3.8 printed, directions building to once or twice daily and refusing the rinse; the shelf’s complete dose, both terms standing | $37.00 for 4 fl oz at the maker (about $9.25 an ounce) |
| The Ordinary Glycolic Acid 7% Exfoliating Toner | The attainable leave-on, 85: glycolic acid second of 42 at 7 percent, pH approximately 3.6 printed with the maker’s pKa note, once daily in the evening | $13.50 for 8 fl oz at Sephora (about $1.69 an ounce) |
| The Ordinary AHA 30% + BHA 2% Peeling Solution | The timed record, 82: the shelf’s largest strength, a 30 percent acid total with salicylic acid eighth of 24, pH 3.5 to 3.7, capped by its maker at ten minutes and twice a week, experienced users; the number and its ration on one page | $9.50 for 1 fl oz at Sephora ($9.50 an ounce) |
| CeraVe Renewing SA Cleanser | The rinse-off record, 76: salicylic acid sixteenth of 27 and undosed, behind niacinamide fifth and gluconolactone sixth, its fragrance-free claim cashed; the identical tube stands at 78 on the cleanser Card on the cleanser basis, disclosed in both places | $15.99 for 8 fl oz at Ulta (about $2.00 an ounce) |
| Jack Black Bump Fix | The leave-on drug, 73: salicylic acid 2 percent on its federal panel, alcohol denat. second on the captured inactive list, lactic acid named by the maker and undosed, its position unpinned and printed as unpinned; pill-less, its merchant page unpinned this pass | $28.00 for 6 fl oz at the maker (about $4.67 an ounce) |
| Brickell Renewing Face Scrub | The physical record, 62: pumice second of 23 while the copy leads with jojoba beads standing twelfth, two lists in circulation, sold scented with no Fragrance entry, a printed 30-second massage and no weekly frequency captured | $22.00 for 4 fl oz at the maker (about $5.50 an ounce) |
| St. Ives Fresh Skin Apricot Scrub | The second physical, 52: walnut shell powder second of 24, Fragrance nineteenth, the named apricot extract twenty-third, no acid of any kind, directions three to four times a week; the identical scrub stands at 46 on the cleanser Card, disclosed in both places | $4.99 for 6 oz at Target (about $0.83 an ounce) |
| Neutrogena Hydro Boost Exfoliating Cleanser | Sent home, 44: glycolic acid eleventh and lactic acid thirteenth, both undosed, Fragrance standing between them, the line’s named hyaluronic acid seventeenth and last, sold as gentle enough for daily use; neither term of the dose printed, and no buy pill | $10.49 for 5 fl oz at Meijer (about $2.10 an ounce) |
The discipline for using any of them is the Card’s, unchanged: read the contact class in the card’s tag before the score, keep one acid instrument in a routine at a time, and let the printed caps govern the timed records exactly as printed. The standing offer of this column applies to the shelf in its own terms: the first maker to print both terms, strength and minutes, on a rinse-off acid’s consumer record, the label or the product page a buyer reads, will be named here, at the top of a re-argued column, the same day its record can be read. The proof that it can be done already stands on the mask Card, where the run’s highest score prints its 2 percent with a ten-minute ceiling beside it. The documents exist in every maker’s files. On this shelf they are simply addressed to the hours, and the seconds go unread.
What this page does not claim
On the evidence. This page scores nothing and tests nothing. Every score, row, price, position and percentage is Verdict Card No. 93’s or No. 95’s, reproduced exactly as those Cards published them, and the Cards’ own evidence discipline stands behind them: the desk grades published ingredient lists in the maker’s order, makers’ claims graded as claims, reported wear labelled as reported wherever it appears, and prices per ounce with the arithmetic printed, and asserts nothing about what any acid does to any skin. The counts this Take adds, strengths on four of eight, pH on three, the class census of three leave-ons, one timed record and four rinse-offs, a wear time on seven of eight mask records, are counts of the two Cards’ printed records and are printed as counts so they can be recounted.
On the brief’s premises, and the precision this issue carries. This issue was briefed on a pairing and a distribution, and the distribution survived the record while the pairing did not. Survived: the acid shelf is the run’s fullest dose column, a dosed headline active on four of eight exfoliator records and a printed pH on three; the mask Card’s winner doses in its name with a printed ceiling; the dose is a product of strength, time and contact, and the two Cards print the first term far more completely than the second. Did not survive, and is corrected here rather than absorbed: the brief’s rinsed bottle at 2 percent in sixty seconds. No rinse-off on Card No. 93 prints 2 percent of anything; the four dosed records are the three leave-ons and the timed peel, and the two rinse-off acid cleansers carry their acids undosed, at sixteenth of 27 and at eleventh and thirteenth of 17. And no cleanser on the Card prints a sixty-second contact; the rinse-off class’s one printed duration is the Brickell scrub’s thirty seconds, and the sixty seconds in the run’s memory belongs to Card No. 67’s cleanser record and Take No. 8, the INKEY List’s printed minute. The Take is therefore argued in the form the record supports, which is the stronger form: the number clusters where the contact is long, is rationed by printed minutes where the contact is timed, and vanishes where the contact is briefest, and the makers’ own caps are the evidence that the number alone was never the dose. One more count is stated exactly: five of the eight exfoliator records leave the skin by water, the timed peel and the four rinse-offs, and three stay on it.
On what exfoliators do. Nothing on this page says any acid brightens, clears or renews any face, and nothing says any strength or any contact time is the right dose for any reader. Efficacy is graded nowhere here: where a figure like the peel’s 30 percent or the masque’s ten minutes is discussed, it is discussed as a published number and a purchasing instrument, not as a recommendation of either strength or either duration. What is graded is the document the buyer is handed: where the actives stand, what is dosed, what is timed, and which class the bottle belongs to. The desk opened no bottle and timed no wash. The argument is about what is printed for a reader to read before the rinse, and on eight labels what is printed is the strength at the long end of the shelf and the name at the short end.
On the photographs, and on the record moving. There are no photographs of ranked products on this page because there are none to print: the photo bank holds no exfoliant, peel or masque product photography, a gap both Cards name on their own pages, and the hero and figure here are frames of the subject itself, the exfoliator ranking’s own hero and a portrait at reading distance, captioned for what they show, which is a wearer, not a product. The record itself moves underneath this argument: two bottles on the exfoliator Card carry earlier grades on the cleanser Card and print both numbers (the CeraVe cleanser at 78 there and 76 here, the St. Ives scrub at 46 there and 52 here, each disclosed on its card); the glycolic toner’s price has already moved once, to $13.50 at Sephora, and its value arithmetic moved with it; one door on the shelf stands unpinned, the Bump Fix’s merchant page, owed to the November pass; and the mask Card’s rested records, a dosed drug-panel mask among them, wait for the follow-up Card whose pass will be the next reading of this shelf’s two columns. The scores and the rule stand as published until a cited record changes; when one does, the Card moves first and this Take is re-argued from it, in the open.
Questions, answered from the record
Does 2 percent salicylic acid mean the same thing in every bottle?
No, because the number is a strength and the dose is the strength multiplied by the contact, and the contact is a property of the class. On Verdict Card No. 93 the 2 percent stands in three different instruments: in the Paula’s Choice liquid it is a leave-on, applied once or twice a day and not rinsed, working for hours; in the Jack Black Bump Fix it is a leave-on drug dose on a federal panel; and in The Ordinary’s peeling solution the same 2 percent rides under a 30 percent acid total inside a printed cap of ten minutes, twice a week at most. On Verdict Card No. 95 the figure stands in a fourth: a masque with a printed ceiling of ten minutes on dry skin. Same digits, contact running from ten rationed minutes to all day. And in the class where the contact is briefest, the rinse-off cleansers, the number is not printed at all: the CeraVe’s salicylic acid stands sixteenth of 27 undosed, and the sent-home Neutrogena’s two acids stand eleventh and thirteenth undosed. The percentage is the beginning of a dose. The class is the rest of it.
What is the best exfoliator on this site’s record?
Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant, at 88 on Verdict Card No. 93: a leave-on whose dose is printed in its name, whose salicylic acid stands fourth of nine, whose pH is printed at 3.2 to 3.8, and whose directions build to once or twice daily and say do not rinse, at $37.00 for 4 fl oz at the maker. The Ordinary Glycolic Acid 7% Toner is second at 85, the attainable leave-on at $13.50 for 8 fl oz. The Ordinary’s peeling solution is third at 82, the shelf’s strongest numbers under its maker’s strictest caps. Behind them the shelf sorts by class before it sorts by quality: the rinse-off record at 76, a leave-on drug at 73, two physical scrubs at 62 and 52, and a cleanser sent home at 44 for selling two undosed acids with Fragrance standing between them.
Why does the strongest bottle on the shelf carry the strictest limits?
Because its maker is printing the second term of the dose, and the strictness is the confession this Take is built on. The Ordinary’s peeling solution carries the exfoliator shelf’s largest figures, a 30 percent acid total with 2 percent salicylic acid, its pH printed at 3.5 to 3.7, and it is the one record on the Card whose directions ration the number: no more than ten minutes on the skin, no more than twice a week, experienced users only. The same house sells a 7 percent glycolic toner with no minute cap at all, because that one stays on. Read together, the two records are the maker’s own arithmetic: strength is traded against time, openly, in print. The masque shelf repeats it, where the run’s highest score, The Ordinary’s salicylic masque at 92 on Card No. 95, prints its 2 percent with a ten-minute ceiling beside it. Where a maker prints both terms, the number can be spent. Where he prints the strength alone, the buyer is holding half a dose.
Is a rinse-off acid a fraud?
No, and nothing on this page grades it as one. The CeraVe Renewing SA Cleanser stands at 76 on Verdict Card No. 93 as the shelf’s designated rinse-off record, graded as the instrument it is: a cleanser whose salicylic acid stands sixteenth of 27, behind niacinamide fifth and gluconolactone sixth, supporting a wash rather than starring in it, its fragrance-free claim cashed. The physical scrubs dose by particle and pressure and are graded on that record, pumice second of 23 on the Brickell. What this Take charges is typography, not the class: a name that borrows the leave-on shelf’s authority, Renewing SA with the acid undosed at sixteenth, or an exfoliating cleanser whose two acids stand eleventh and thirteenth with Fragrance between them, which is the record the Neutrogena was sent home on at 44. A rinse-off is an honest instrument with a short contact. The fraud risk begins where its label is read as a leave-on’s promise.
Why was the Neutrogena sent home?
Because it is the shelf’s rinse-off problem in its completed form. The Hydro Boost Exfoliating Cleanser publishes its full 17-item list, and the list is the charge: cellulose seventh as the only positioned mechanism, citric acid ninth, glycolic acid eleventh and undosed, Fragrance twelfth, lactic acid thirteenth and undosed, and the hyaluronic acid the line is named for seventeenth and last, in a rinse-off sold as gentle enough for daily use with an acid sunburn alert on its retail packaging. The two acids that do the selling stand either side of the scent, dosed nowhere, in the class where a dose would need its minutes printed to mean anything and no minutes are printed either. It stands at 44 on Verdict Card No. 93, with no buy pill: the one record on the shelf that offers the buyer neither term of the dose, neither the strength nor the time, only the names.
What would change this Take?
Both terms, printed in every class. The column reopens the day a rinse-off acid cleanser prints its acid’s percentage and its contact time on the record the buyer reads, so its number can be compared with the leave-ons it is shelved beside; or the day the makers who already print caps on their strongest bottles extend the same honesty down the shelf, minutes on the masques that print none, a frequency on the scrub that prints a massage and no count; or the day the exfoliator Card’s next pass finds the dosed count moving off the leave-on class, four of eight with all four standing on records that stay or are timed. Until then the record stands as Cards No. 93 and No. 95 printed it in October 2026: strengths on four of eight, pH on three, the dosed numbers clustered where the contact is long, the rinse-off acids carrying the name without the number, and the shelf’s strongest bottle rationed by its own maker to ten minutes.

The records this issue argues from stand in full at the exfoliator ranking, Verdict Card No. 93, and the mask ranking, Verdict Card No. 95, where every list quoted here is printed in its maker’s order and every bottle carries its own card. The shelf above the sink continues at the toner Card, No. 94, where the exfoliating liquids graded on No. 93 are cross-referenced as the step’s other species, the cleanser Card, No. 67, where this shelf’s rinse-off record and its second scrub were first graded, the serum Card, No. 91, and the body lotion Card, No. 92, and the routine that orders them stands at the skincare Decoder. The kinship runs three ways: Take No. 7 is the parent argument, the number is not the dose, since there a complete rating stood printed on every bottle with the dose that earned it standing nowhere beside it, and here the dose’s first term is printed in full and its second term is left to the buyer’s routine, the rating’s missing half become the strength’s; Take No. 8 governs the time term, the minute is the dose, since there the cleanser shelf printed its strength only where a drug panel compelled it and its time almost nowhere, one printed minute in eight records, and here the acid shelf prints its strengths freely and rations them by minutes in its own caps, the second term arriving as a warning rather than a specification; and Take No. 14 is the nearest sibling, the number is in another country, since there the percentage existed entire and was addressed to another audience, and here the strength is addressed to everyone and is worth a different amount in each reader’s hands, because the class that decides its value is printed in smaller type than the number; and Take No. 16, the step is not a species, where the toner shelf’s own makers will not define the step they sell, one printing on its own page that its lotion is different from a toner while selling it in the toner slot, one filing its tonic at the toner step in its own routine guide, the founding botanical dosed on none of eight records, and the shelf’s one printed dose standing in a maker’s FAQ rather than on its bottle. The franchise so far: No. 1, grooming is sold by the step and works by the habit; No. 2, the number nobody prints; No. 3, one tube, two honesties; No. 4, the pair graded as one record; No. 5, the name is not the number; No. 6, the name is not in the list; No. 7, the number is not the dose; No. 8, the minute is the dose; No. 9, the ritual is not an ingredient; No. 10, the hold is an adjective; No. 11, the name is not an ingredient; No. 12, the burn is not the proof; No. 13, the copy is not the list; No. 14, the number is in another country. No. 16, the step is not a species. How every score on this site is built is set out in the methodology. The Takes continue by number; the next one starts, as this one did, from a record that already exists or a blank that is printed as one.
