Two glycolic acid toners, one point of concentration apart: The Ordinary at 7%, Minimalist at 8%. The percentage on a glycolic acid label says how much acid is in the formula, not how much of it is in free acid form, and that depends on pH. This page compares the two on what each brand and our catalogue publish, and says where the record runs out.
The Published Specification, Side by Side
The table draws on our product catalogue (products.json), the brand product pages we read in this session, and for Pixi on a third-party review. We did no testing ourselves.
| Specification | The Ordinary | Minimalist | Pixi Glow Tonic |
|---|---|---|---|
| Labelled glycolic acid | 7% | 8% | 5% (Lab Muffin Beauty Science review of Pixi Glow Tonic) |
| Published pH | 3.5 to 3.9 (catalogue; The Ordinary product page also says approximately 3.6) | 3.4 to 4.0 (Minimalist India product page; the global page shows none) | 4 to 5, per Lab Muffin Beauty Science review of Pixi Glow Tonic; no brand page found |
| Free acid estimate (our arithmetic) | About 3.2 to 4.8% | About 3.2 to 5.8% | About 0.3 to 2.0% |
| Acid form on the label | Glycolic acid | Glycolic acid; the brand says it is in free acid form | Glycolic acid and ammonium glycolate |
| Other acids in the ingredient list | Citric acid listed, plus amino acids | None listed | None named beyond ammonium glycolate |
| Fragrance listed | No | No; the brand says fragrance free | Yes, in the list the review reproduces |
| Published size | 100 ml / 240 ml | 150 ml | 100 ml (per the review) |
Free acid estimates use label percentage ÷ (1 + 10^(pH − 3.83)), with the pKa of 3.83 listed by PubChem. They assume the label percentage is total acid, which is our assumption for all three. The ranges for The Ordinary and Minimalist overlap, so the published data cannot say which is stronger.
Why the Number on the Label Is the Wrong Number
The FDA says the extent of exfoliation from an AHA product depends on the type and concentration of the AHA, its pH, and other ingredients. Our percentage guide works through the arithmetic in full: by our calculation a 7% formula at pH 3.5 has about 4.8% free acid, while a 10% formula at pH 4.5 has about 1.8%, so the product with the smaller label number can carry more free acid.
That is why a pH range matters. A pH of 3.4 to 4.0 on an 8% label spans roughly 3.2% to 5.8% free acid, a 1.8-fold spread, and our statistics page shows the same calculation for the brands that publish a range.
The Ordinary Glycolic Acid 7% — the Documented One
The Ordinary's product page lists 7% glycolic acid, a pH of 3.5 to 3.9 (the text says approximately 3.6), a size of 100 ml or 240 ml, and no fragrance in the full ingredient list of 42 entries. By our arithmetic that pH range gives roughly 3.2% to 4.8% free acid, and about 4.4% at pH 3.6.
The brand's page says the formula includes a Tasmanian pepperberry derivative that it says helps soothe skin and reduce irritation commonly associated with exfoliation. That is the brand's claim; we found no independent study of it. The same page says it should not be used on sensitive, peeling or compromised skin, and advises sun protection because of increased sun sensitivity after use. It also says the toner can be applied to the scalp and to small areas of the body with rough and bumpy skin.
Minimalist Glycolic Acid 8% — the Higher Label Percentage

Minimalist Glycolic Acid 8% Exfoliating Toner
Glycolic acid: 8%
The Minimalist product page lists 8% glycolic acid and a ten-item ingredient list: bamboo water, glycolic acid, triethanolamine, propanediol, aminomethyl propanol, phenoxyethanol, sodium hyaluronate, ethoxydiglycol, ethylhexylglycerin and trisodium ethylenediamine disuccinate. It says the product is fragrance free, essential oil free and silicone free, with a net quantity of 150 ml. Our catalogue records a published pH of 3.4 to 4.0, which gives roughly 3.2% to 5.8% free acid by our arithmetic; the figure is listed on Minimalist's India product page, though not on its global page.
The brand states that its glycolic acid is in free acid form, which it says "represents how much acid is available in non-ionized form". That is the brand's description, and the pH range above is what lets you place it on the same scale as The Ordinary. The page describes it as a multi-purpose exfoliator for face, body, underarms and scalp.
The brand's ingredient list contains no niacinamide. If you are trying to combine the two ingredients, our glycolic acid vs niacinamide guide covers what the sources say about pairing them.
Where Pixi Glow Tonic Fits
Pixi Glow Tonic comes up in the same comparison. The only source we read for it is Lab Muffin Beauty Science review of Pixi Glow Tonic, published in 2015, which gives 5% glycolic acid, states the pH as 4 to 5, and calls it a relatively weak exfoliating product. The ingredient list the review reproduces includes both glycolic acid and ammonium glycolate, witch hazel, horse chestnut and ginseng extracts, aloe leaf juice, glycerin and fragrance. Readers in the comments note that the formulation changed over time, and we could not load a current Pixi brand page, so treat these details as dated.
On those figures its free acid by our arithmetic is roughly 0.3% to 2.0%, below The Ordinary's range. That makes it a different strength of product, not a like-for-like alternative to a 7% toner. We found no source explaining what ammonium glycolate does in the formula, so we draw no conclusion from it.
What the Formulas Contain Beyond the Acid
This table repeats the brand ingredient lists we read (Pixi's from the review).
| Formula element | The Ordinary | Minimalist | Pixi Glow Tonic |
|---|---|---|---|
| Water base | Water, rose water, cornflower water, aloe leaf water | Bamboo water | Water, aloe leaf juice |
| Glycerin, hyaluronate, amino acids | Glycerin, amino acids, PCA | Sodium hyaluronate | Glycerin, glucose, fructose and other sugars |
| Plant extracts named | Panax ginseng root, Tasmannia lanceolata | None beyond bamboo water | Witch hazel, horse chestnut, ginseng |
| Ingredient list length | 42 entries | 10 entries | 21 entries |
A shorter list means fewer candidates if something disagrees with your skin; that is our reading, and Cleveland Clinic makes a related point when it says using fewer active ingredients helps you isolate the cause of a problem.
What We Cannot Tell You
This site does not test products, and a comparison built on published specification has limits.
- We cannot tell you which one works better. No study we found compares them.
- We cannot give Pixi a current free acid value. The only pH we found is a 2015 reviewer's statement.
- Formulations change. Check the carton against the lists here before assuming a match.
- Concentration is not the only safety variable. Frequency, what else is in your routine and sun exposure matter too; see our side effects guide.
How to Choose on What Is Actually Published
On our catalogue figures, The Ordinary's free acid range (about 3.2% to 4.8%) sits inside Minimalist's (about 3.2% to 5.8%), so the published data supports no claim that either is stronger in practice. If you want the narrower range, The Ordinary's pH of 3.5 to 3.9 is narrower than Minimalist's 3.4 to 4.0, and its brand page states approximately 3.6.
If you want the shortest ingredient list, Minimalist's ten entries are the leanest here. If you want a lower free acid estimate on published figures, Pixi's is lower, with the 2015 caveat above. If you cannot tell them apart on the disclosed information, that is a correct conclusion: our pH disclosure audit found only 8 of 26 readable brand pages publish a numeric pH.
If You Are Switching Between Them
These steps are our suggestions, built on Cleveland Clinic's advice to start once or twice a week and to test a little on one area first. Treat a switch as introducing a new active.
1
Drop your frequency back. Cleveland Clinic advises once or twice a week when starting; our suggestion is to return to that range on the new product.
2
Test on one area first. Cleveland Clinic says to test a little bit on one area of skin and see how your body reacts.
3
Change one thing at a time. Cleveland Clinic says using fewer actives lets you isolate what is causing an issue.
4
Build frequency slowly. Cleveland Clinic says to work up to nightly use only if your skin is tolerating it. Our frequency guide covers the full progression.
Important: The FDA says AHAs may increase your skin's sensitivity to the sun and advises sun protection while using them and for a week afterwards. Cleveland Clinic advises broad-spectrum sunscreen of SPF 30 or higher; our house line is SPF 30+.
Common Mistakes in This Comparison
Treating 8% as 14% stronger than 7%. The ratio of the labels is 1.14, but the published pH ranges overlap, so the free acid ranges overlap too.
Reading "gentle" as "safe". A lower free acid product such as Pixi's is still an AHA, and the FDA says AHAs may increase sun sensitivity. See our sun exposure guide.
Stacking two of them. No source we read tests two glycolic toners together; Medical News Today lists using glycolic acid too frequently or at too high a concentration among the causes of irritation. Pick one and see our routine guide.
Frequently Asked Questions
Is Minimalist 8% a good alternative to The Ordinary 7%?
On published specification they are close. Both are glycolic acid toners and both list triethanolamine and aminomethyl propanol; The Ordinary also lists citric acid, which Minimalist's ten-item list does not. Our catalogue records a published pH of 3.5 to 3.9 for The Ordinary and 3.4 to 4.0 for Minimalist, which by our arithmetic gives roughly 3.2 to 4.8% and 3.2 to 5.8% free acid, so the ranges overlap and the data cannot say which is stronger. Whether one suits you better depends on tolerance and format, not on the one-point label difference.
Which glycolic acid brand is best?
We do not name a best brand. The FDA says the extent of exfoliation from an AHA product depends on the type and concentration of the AHA, its pH and its other ingredients, so concentration and pH together are the useful specification. our pH disclosure audit found only 8 of the 26 brand product pages we could read publish a numeric pH, so for most brands the free acid cannot be estimated.
Is 8% glycolic acid safer than 10% for sensitive skin?
Not reliably, because the percentage alone does not determine strength. By our arithmetic an 8% product at pH 4.0 has about 3.2% free acid while a 10% product at pH 4.5 has about 1.8%. Cleveland Clinic lists sensitive skin, dry skin, rosacea, eczema and active skin infections as reasons for caution with glycolic acid, and the FDA says AHAs may increase sun sensitivity. A low frequency to start and a patch test on one area (Cleveland Clinic) are the safeguards the sources give. See our sensitive skin guide.
Which brands make a 7% glycolic acid toner?
The Ordinary lists 7%. Other toners we track sit at other concentrations: Minimalist at 8%, Good Molecules at 3.5% and The INKEY List at 10%, and Lab Muffin Beauty Science review of Pixi Glow Tonic gives Pixi Glow Tonic as 5%. Our glycolic acid toner roundup lists the full set.
Can I use Minimalist 8% glycolic toner on underarms?
The Minimalist product page describes it as a multi-purpose exfoliator for face, body, underarms and scalp, and its directions say to apply it to face, body or neck, so body use is within its published intended use. Healthline says to check with a doctor first about freshly shaved skin, and Medical News Today says to wait until broken or sunburned skin has healed. See our body and underarm guide.
Is a higher glycolic acid percentage always stronger?
No. The percentage tells you how much acid is in the formula; pH governs how much of it is in free acid form. By our arithmetic (Henderson–Hasselbalch, using the pKa of 3.83 listed by PubChem), 7% at pH 3.5 has about 4.8% free acid while 10% at pH 4.5 has about 1.8%. Our percentage guide has a calculator for any product where you know both numbers.
Do these toners publish their pH?
Our catalogue records 3.5 to 3.9 for The Ordinary and 3.4 to 4.0 for Minimalist. The Ordinary's product page we read lists pH 3.5 to 3.9 and the text says approximately 3.6; Minimalist's India product page lists pH 3.4 to 4.0; its global page shows none. Lab Muffin Beauty Science review of Pixi Glow Tonic states Pixi Glow Tonic's pH as 4 to 5, and we did not find a Pixi brand page that gives one. Across our catalogue, our pH disclosure audit found 8 of 26 readable brand pages publish a numeric pH.
Does the Minimalist glycolic toner contain niacinamide?
No. The Minimalist product page lists bamboo water, glycolic acid, triethanolamine, propanediol, aminomethyl propanol, phenoxyethanol, sodium hyaluronate, ethoxydiglycol, ethylhexylglycerin and trisodium ethylenediamine disuccinate, with no niacinamide. If you are planning to pair the two ingredients, see our glycolic acid vs niacinamide guide.
Can I switch from The Ordinary straight to Minimalist?
Treat it as a new product. Cleveland Clinic says to start glycolic acid once or twice a week, to test a little on one area of skin first, and that using fewer actives helps you isolate what is causing an issue. Dropping back to a low frequency when you switch is our suggestion. Our frequency guide covers rebuilding tolerance.
How long before I see results from a glycolic acid toner?
Cleveland Clinic says over-the-counter glycolic acid products may take several months of consistent use before skin looks brighter or pigmentation is more even. A 2015 manufacturer-run study of a four-product regimen found 87% of 52 volunteers self-reported improved texture over 21 days. Our before and after timeline sets out the caveats.
Is there a cheaper alternative to The Ordinary glycolic toner?
We do not give prices on this site, so we cannot rank by cost. Other toners at nearby strengths are Minimalist at 8% and Good Molecules at 3.5%; Good Molecules publishes no pH in our catalogue, so its free acid cannot be estimated. Compare on what is disclosed rather than on the label percentage.
Pixi Glow Tonic vs The Ordinary — which is stronger?
On the published figures The Ordinary is stronger. Lab Muffin Beauty Science review of Pixi Glow Tonic gives Pixi Glow Tonic as 5% glycolic acid at pH 4 to 5 and calls it a relatively weak exfoliating product. By our arithmetic that is roughly 0.3 to 2.0% free acid, against roughly 3.2 to 4.8% for The Ordinary's 7% at pH 3.5 to 3.9. The review is from 2015 and the formula may have changed since; we did not find a current Pixi page to check.
