Two glycolic acid toners, one point of concentration apart. The Ordinary at 7%, Minimalist at 8%. Every comparison site prints those two numbers side by side and calls it an answer.
It isn't one. The percentage on a glycolic acid label tells you how much acid is in the bottle, not how much of it is working — and on that second question, these two products are not equally documented. This page compares them on what each brand actually publishes, and is honest about where the published record runs out.
The Published Specification, Side by Side
Everything in this table comes from a brand's own product page or an independent ingredient listing, not from our own testing.
| Specification | The Ordinary | Minimalist | Pixi Glow Tonic |
|---|---|---|---|
| Labelled glycolic acid | 7% | 8% | 5% |
| pH published by brand | Yes — approx. 3.6 | No | No |
| Free acid value estimable? | Yes, approx. 4–4.8% | Not from published data | Not from published data |
| Acid form on the label | Glycolic acid | Glycolic acid, stated as free acid form | Glycolic acid + ammonium glycolate |
| Second exfoliating acid | None | None | None |
| Fragrance listed | No | No | Yes |
| Published size | 100 ml / 240 ml | 150 ml | 100 ml / 250 ml |
The row that decides this comparison is the second one, not the first.
Why the Number on the Label Is the Wrong Number
Glycolic acid only exfoliates in its un-neutralised form. In any finished formula, some proportion of the acid sits in that active state and the rest is neutralised into a salt — and the split is governed by the product's pH. The percentage of the total that remains active is called the free acid value, and it is the number that actually corresponds to how the product behaves on skin.
The practical consequence is large enough to invert a label comparison. A 7% formula at pH 3.5 delivers roughly 4.8% free acid; a 10% formula buffered up to pH 4.5 delivers about 1.8%. The product with the smaller number on the front is more than twice as strong. Our glycolic acid percentage guide works through this in full and includes a calculator that will estimate free acid value for any product where you know both figures.
Which is exactly the problem here. You can run that calculation for one of these three toners.
The Ordinary Glycolic Acid 7% — the Documented One
The Ordinary's 7% toner is the reference product in this category, and the reason is less about the formula than about the paperwork. A pH of approximately 3.6 has been published for it, and that single disclosed figure is what allows its free acid value to be estimated at roughly 4–4.8% — meaning something close to two-thirds of the labelled acid is in active form.
The supporting formula is unusually well populated for the tier: Tasmanian pepperberry, Panax ginseng root, aloe leaf water, and a substantial set of amino acids and PCA. Tasmanian pepperberry in particular is included in AHA formulas for its reported ability to reduce the sensory sting of acid exfoliation, which is a formulation choice rather than a strength claim.
The honest limitation: the brand's current US product page states the 7% concentration but does not restate a pH figure alongside it. The pH number in wide circulation is one the brand has published historically and which retailer specification listings continue to carry. It is better documented than its competitors here, but "better documented" is not the same as "documented on the box today".
Minimalist Glycolic Acid 8% — the Stronger Label, the Thinner Disclosure
✓ Glycolic acid verified
Minimalist Glycolic Acid 8% Exfoliating Toner
Glycolic acid: 8%
Minimalist's formula is a genuinely lean one: bamboo water as the base, glycolic acid second on the list, sodium hyaluronate for hydration, and the same pH-adjusting pair The Ordinary uses — triethanolamine and aminomethyl propanol. There is no second acid, no fragrance, and the ingredient list runs to ten entries.
The brand states that its glycolic acid is present in free acid form, describing it as what "permits it to work at 08% concentration". That is a meaningful claim, and it is the right claim to be making. What is missing is the number that would let anyone check it: Minimalist does not publish a pH for this formula. Without it, the 8% cannot be converted into a free acid value, and so cannot be placed on the same scale as The Ordinary's 7%.
A correction worth stating plainly: this product is frequently described — including previously on this site — as containing niacinamide. It does not. The brand's published ingredient list contains no niacinamide, and neither do the independent ingredient databases that carry it. Minimalist sells other toners that do contain niacinamide, which is the likely source of the confusion. If you are trying to combine the two ingredients, our glycolic acid vs niacinamide guide covers the pH clash and how to sequence them.
The brand's own directions describe use on face, body or neck, which makes this one of the few toners in the category whose published intended use explicitly includes body application.
Where Pixi Glow Tonic Fits
Pixi Glow Tonic comes up constantly in the same comparison, usually positioned as the gentler option, and on published specification that positioning holds — but for a reason the 5% label only half explains.
Its ingredient list carries both glycolic acid and ammonium glycolate. Ammonium glycolate is the neutralised salt of glycolic acid, and its presence on a label is a direct signal that the formula has been buffered upward rather than left at the low pH where glycolic acid is mostly active. Independent testing by Lab Muffin Beauty Science reports the product's pH at 4–5, which is consistent with that reading and well above The Ordinary's approximately 3.6.
So the gap between Pixi and The Ordinary is wider than 5% against 7% implies. That is not a criticism of the product — a buffered, lower-free-acid formula is a reasonable design for daily use and for skin that reacts badly to stronger exfoliation. It is simply not the like-for-like alternative that the two percentages suggest. Pixi's formula also lists witch hazel, horse chestnut and fragrance, none of which appear in the other two.
Important: Fragrance is one of the more common contact irritants in leave-on skincare. If your skin reacts unpredictably to toners, the fragrance in Pixi's formula is a variable the other two products do not introduce.
What the Formulas Contain Beyond the Acid
Once concentration and pH are set aside, the three formulas diverge in what they surround the acid with — and this is where a genuine preference can be formed on published information alone.
| Formula element | The Ordinary | Minimalist | Pixi Glow Tonic |
|---|---|---|---|
| Base | Water, rose and cornflower waters | Bamboo water | Water, aloe leaf juice |
| Humectant / hydrator | Glycerin, PCA, amino acids | Sodium hyaluronate | Glycerin |
| Soothing or anti-sting additions | Tasmanian pepperberry, ginseng, aloe | None listed | Aloe, ginseng, horse chestnut |
| Astringent | None | None | Witch hazel |
| Ingredient list length | Long (30+) | Short (10) | Medium (20+) |
A short ingredient list is not automatically the safer choice, but it is the more predictable one: fewer entries means fewer candidates when something disagrees with your skin. A longer list like The Ordinary's buys soothing and hydrating support at the cost of that predictability. Neither approach is wrong, and the trade-off is visible on the label, which is the point.
What We Cannot Tell You
This site does not test products, and a comparison built on published specification has hard limits that are worth naming rather than papering over.
- We cannot tell you which one works better. That would require controlled use on comparable skin, which no one in this comparison — including the sites that rank for it — has actually done.
- We cannot give Minimalist or Pixi a free acid value. Neither publishes a pH. Estimating one from the ingredient order would be inventing a number, and an invented number is worse than an absent one.
- We cannot confirm current formulations. Ingredient lists are revised without announcement, and we found more than one version of Minimalist's list in circulation. Check the carton against the list here before assuming a match.
- Concentration is not the only safety variable. Frequency, what else is in your routine, and sun exposure all matter at least as much — see our side effects guide.
How to Choose on What Is Actually Published
If you want the formula whose real strength you can verify, The Ordinary is the only one of the three where that is currently possible. That is a genuine advantage and it is independent of any opinion about the product.
If you want the shortest, most predictable ingredient list, Minimalist's ten-entry formula is the leanest here, and its stated free acid form is the right claim for a brand to make — you are simply taking it on trust rather than checking it.
If you want the gentlest of the three on published evidence, Pixi's buffered formula is it, with the caveat that it is meaningfully milder than its 5% label implies, and that it introduces fragrance and witch hazel.
And if the honest answer is that you cannot tell them apart on the disclosed information — that is a correct conclusion, not a failure to research. Across our catalogue, 91% of glycolic acid products disclose a concentration and almost none disclose a pH. The category's transparency problem is not something a comparison table can solve.
If You Are Switching Between Them
Moving between these products is not a like-for-like swap, because you are moving between formulas whose active strength you can and cannot verify. Treat any switch as introducing a new active.
1
Drop your frequency back. Return to two applications per week for the first fortnight on the new product, whatever you had built up to on the old one.
2
Patch test first. Apply to a small area on the inner forearm or jawline for three consecutive uses before applying to the full face.
3
Change one thing at a time. Do not introduce a new toner in the same week as a new retinoid, vitamin C or second acid — if something reacts, you will not know which product caused it.
4
Rebuild frequency slowly. Add one application per week only once two weeks have passed without stinging, tightness or flaking. Our frequency guide covers the full progression.
Important: Glycolic acid increases UV sensitivity during use and for about a week after stopping, at every concentration discussed on this page. Daily broad-spectrum SPF 30 or higher is not optional while any of these products is in your routine.
Common Mistakes in This Comparison
Treating 8% as 14% stronger than 7%. Without both pH figures, the one-point difference is not a strength difference at all. It is a labelling difference.
Assuming the pricier product is the stronger one. Tier position in this category tracks brand positioning and packaging far more than it tracks free acid value. The best-documented formula here is also one of the least expensive.
Reading "gentle" as "weak" or "weak" as "safe". A buffered, lower-free-acid product like Pixi's is easier to tolerate, but it is still an AHA and still raises sun sensitivity. Gentleness changes the irritation risk, not the sunscreen requirement.
Stacking two of them. Using more than one glycolic toner in a routine is over-exfoliation with extra steps. Pick one and see our routine guide for where it belongs in the sequence.
Frequently Asked Questions
Is Minimalist 8% a good alternative to The Ordinary 7%?
On published specification they are closer than the 8% versus 7% gap suggests. Both are pure glycolic acid toners with no second exfoliating acid, and both use the same pH-adjusting chemistry (triethanolamine and aminomethyl propanol). The meaningful difference is disclosure: The Ordinary's pH has been published at roughly 3.5–3.7, so you can estimate its free acid value, while Minimalist does not publish a pH — so its 8% cannot be converted into a comparable strength number. Whether one suits you better depends on tolerance and format preference, not on the one-point concentration difference.
Which glycolic acid brand is best?
There is no single best brand, and any page that names one without telling you the pH is ranking on marketing rather than chemistry. What separates glycolic acid products on published specification is the combination of concentration and pH — which together determine free acid value, the portion of the acid that is actually active. Brands that publish both let you verify what you are buying. Most publish neither, or only the percentage. That disclosure gap is the most useful thing to sort brands by.
Is 8% glycolic acid safer than 10% for sensitive skin?
Not reliably, because the percentage alone does not determine strength. An 8% formula at a low pH can deliver more free acid than a 10% formula buffered to a higher pH. The FDA notes AHAs increase sun sensitivity at any concentration. If you have sensitive skin, the more useful safeguards are starting at a low frequency, patch testing, and choosing a product whose pH you can actually find out — see our sensitive skin guide.
Which brands make a 7% glycolic acid toner?
The Ordinary's Glycolic Acid 7% Exfoliating Toner is the best-known 7% formula and the reference point most other brands are compared against. Around it sit products at nearby concentrations rather than exactly 7% — Minimalist at 8%, Pixi Glow Tonic at 5%, Good Molecules at 3.5% and The INKEY List at 10%. Our glycolic acid toner roundup lists the full set with concentrations.
Can I use Minimalist 8% glycolic toner on underarms?
The brand's own directions describe applying it to face, body or neck, so body use is within its published intended use rather than an off-label workaround. Underarm skin is thin and frequently shaved, which raises the irritation risk considerably. Leave at least 24 hours between shaving and applying any glycolic acid, and see our body and underarm guide for the full approach.
Is a higher glycolic acid percentage always stronger?
No. The percentage tells you how much acid is in the bottle; the formula's pH determines how much of it is in active, un-neutralised form. A 7% product at pH 3.5 delivers roughly 4.8% free acid, while a 10% product buffered to pH 4.5 delivers only about 1.8% — the lower label can be more than twice as strong in practice. Our percentage guide has a calculator that estimates this for any product where you know both numbers.
Do these toners publish their pH?
Only partly, and this is the central problem with comparing them. A pH figure of approximately 3.5–3.7 has been published for The Ordinary's 7% toner, which is what makes its free acid value estimable. Minimalist does not publish a pH for its 8% formula. Pixi does not publish one either, though independent testing has reported it in the 4–5 range. Across our full catalogue, 91% of glycolic acid products disclose a percentage and almost none disclose pH.
Does the Minimalist glycolic toner contain niacinamide?
No. The brand's published ingredient list for the Glycolic Acid 08% Exfoliating Liquid is bamboo water, glycolic acid, triethanolamine, propanediol, aminomethyl propanol, phenoxyethanol, sodium hyaluronate, ethoxydiglycol, ethylhexylglycerin and trisodium ethylenediamine disuccinate — no niacinamide. Minimalist does sell other toners that contain niacinamide, which is a common source of the confusion. 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 rather than a like-for-like swap, because you are moving from a formula whose free acid value you can estimate to one where you cannot. Drop back to two applications a week for the first fortnight and watch for stinging or tightness before returning to your previous frequency. Our frequency guide covers how to rebuild tolerance.
How long before I see results from a glycolic acid toner?
Surface smoothness typically changes first, over the first few weeks of consistent use, while tone and dark-spot changes take considerably longer. Our before and after timeline sets out what is reasonable to expect at each stage, and why the early changes are the most reliable ones.
Is there a cheaper alternative to The Ordinary glycolic toner?
The Ordinary sits at the budget end of the category already, which is why it is usually the benchmark rather than the expensive option in these comparisons. Products at a similar tier include Good Molecules at 3.5% and Minimalist at 8%. Because neither publishes a pH, a lower concentration at an unknown pH may deliver less free acid than the label implies — so compare on what is disclosed rather than on the number alone.
Pixi Glow Tonic vs The Ordinary — which is stronger?
On published specification The Ordinary's is the stronger formula, and by more than the 7% versus 5% labels suggest. Pixi Glow Tonic lists both glycolic acid and ammonium glycolate — the partially neutralised salt form — and independent testing by Lab Muffin Beauty Science reports its pH at 4–5, well above the range where glycolic acid is mostly in free form. The Ordinary's published pH of roughly 3.6 puts far more of its 7% into active form.
