PanOxyl Acne Foaming Wash Review

Who it is for

It is the best 10% benzoyl peroxide wash in our acne face wash guide, picked for face and body. Here is who it suits:

The version we reviewed

PanOxyl’s carton, its tube, the typed text of its official label and its website do not print the same ingredient list, and some store pages that rank for this wash still show a formula retired in 2017. This review covers the 10% wash sold in the US today and reads every fact from the newest printed list, the carton’s.

PanOxyl Acne Foaming Wash ingredients: the full list, mapped

The active ingredient: 10% benzoyl peroxide, printed in the Drug Facts box. The inactive ingredients, as the carton prints them: Aqua, Carbomer Homopolymer Type C, Carbomer Interpolymer Type A, Decyl Glucoside, Dimethicone, Dioctyl Sodium Sulfosuccinate, Glycerin, Oleic Acid, Palmitic Acid, Polyacrylate Crosspolymer-6, Polyoxyl 40 Stearate, Propanediol, Silica, Sodium Chloride, Sodium Citrate, Sodium Hydroxide, Sodium Laurylglucosides Hydroxypropylsulfonate, Sorbitan Stearate, Stearic Acid, t-Butyl Alcohol, Xanthan Gum.

Benzoyl peroxide does the work: the label’s only use is the treatment of acne. Everything else makes the foam, thickens it, softens the rinse and keeps the pH steady. Below, each inactive ingredient in the carton’s order, colored by what it does. New to reading a list? Start with our guide to reading an ingredients list.

Why the order tells you nothing

On a moisturizer or serum, the list runs from most to least, at least above 1%. On this wash it runs A to Z, as the FDA requires for a drug that is not also a cosmetic (21 CFR 201.66). So glycerin 7th and t-butyl alcohol 20th say nothing about how much of either is in the tube. Sites that rank its “top” ingredients are reading the alphabet.

What cleans, and what softens

Five ingredients make the foam and lift oil: decyl glucoside and sodium laurylglucosides hydroxypropylsulfonate, two cleansers made from sugar; dioctyl sodium sulfosuccinate, a wetting agent better known as docusate sodium (FDA substance registry); and two emulsifiers, polyoxyl 40 stearate and sorbitan stearate. The list has no sulfate. Glycerin draws water into the skin, and dimethicone with oleic, palmitic and stearic acid soften the rinse; the carton says the wash “contains moisturizers to help prevent dryness”. Silica is on the list, but PanOxyl never calls this a scrub, and neither do we.

t-Butyl alcohol: a solvent, likely from the thickener

t-Butyl alcohol, 20th on the list, is a small solvent alcohol. It is not ethanol, the drying alcohol, and the EU’s ingredient database lists it as a solvent and denaturant, not as an astringent (CosIng). It most likely comes in with the thickener: the polyacrylate crosspolymer-6 coded on PanOxyl’s label is sold as Sepimax Zen (FDA substance registry), whose safety sheet lists 1 to 5% t-butyl alcohol (Seppic). Crown has not said so, and the amount in the wash is not disclosed.

What it does not have

No fragrance, essential oil, paraben, sulfate or dye, and no exfoliating acid such as glycolic or salicylic acid. The carton says “Free from Parabens, Fragrances and Phthalates”. It also has none of the barrier ingredients CeraVe adds: no ceramide, niacinamide or hyaluronic acid, which is where CeraVe’s 4% wash differs most.

Four ingredient lists for one wash

We read every place PanOxyl prints this wash’s ingredients. They do not agree:

• The carton lists 21 inactive ingredients, including oleic acid and t-butyl alcohol. It is the newest printed list, from November 2025, and the one on this page (DailyMed, 2025).
• The tube in the same official label prints the same list without t-butyl alcohol: 20 entries. Its art dates from July 2024, when t-butyl alcohol left both tube and carton (DailyMed, 2024). Amazon’s listing prints this 20-entry list too.
• The typed Drug Facts text on DailyMed says “purified water”, leaves out oleic acid and adds sorbitol (DailyMed). No printed 10% list we found, from 2011 on, has sorbitol, and this typed list matches, word for word, the typed list the 4% wash had in April 2024, when the 10% got its own label (DailyMed, 2024), so it looks like a copy error.
• PanOxyl’s website showed no inactive list at all from at least September 2024 to June 2026 (archived page), then restored the list it showed until July 2024: 20 entries, “purified water” and no oleic acid (PanOxyl, 2019 copy).

The differences are small, and none touches the active, but they matter if you check a list for something you avoid: oleic acid, a fatty acid, is on the carton and the tube and missing from the website. We found no explanation from PanOxyl; whether the 2024 change was a new formula or a corrected label, the label does not say. Trust the carton in your hand.

Is PanOxyl good for your face?

It can be, if your skin is not sensitive. The tube says “for Face & Body” and the label’s use is acne. Four things to know before it goes on your face:

• 10% is the top of the range, not the start. The AAD suggests starting benzoyl peroxide at 2.5% to avoid dryness, irritation and burning (AAD), and PanOxyl’s FAQ says best practice is to start with the lowest percentage (PanOxyl). Its 4% Creamy Wash is the same base; see 10% vs 4%.
• The label rules out very sensitive skin: “Do not use if you have very sensitive skin” (Drug Facts).
• Keep it off your eyes and lips. The label says so, and Wirecutter’s testers found the wash too harsh and irritating, especially around the eyes (Wirecutter). A 2025 Reddit thread describes swollen eyelids after a benzoyl peroxide wash (thread).
• Dryness is the trade-off. The label’s answer is to use it less often; most people add a plain moisturizer after rinsing.

How long to leave PanOxyl on

The label says to massage it into wet skin for 1 to 2 minutes and rinse thoroughly (Drug Facts). The FDA’s rules for acne washes set no contact time, so those minutes are PanOxyl’s own direction (21 CFR 333.350). What the studies suggest:

• Too short does little on the back. On the back, an 8% wash left on about 20 seconds and rinsed did not cut acne bacteria after 2 weeks, while a leave-on foam did (Leyden, 2010). A 9.8% foam left on 2 minutes cut them about as much as a leave-on product (Leyden and Del Rosso, 2012).
• On the back, the AAD says 2 to 5 minutes before rinsing, to get through the back’s thicker skin (AAD). On the face, follow the label’s 1 to 2 minutes.
• Not overnight. It is a rinse-off wash. Leave-on benzoyl peroxide gels exist for that; this one’s label says to rinse it off, and it would bleach your pillowcase.

On Reddit, the times people report run from a 60-second wash to 10 minutes; one user who tried both strengths thinks “washing off the product barely has an effect” (thread).

PanOxyl 10% vs 4% Creamy Wash

The two tubes look like different products, but their lists are nearly the same. The 10% label uses pharmacy names and the 4% label cosmetic ones: dioctyl sodium sulfosuccinate is diethylhexyl sodium sulfosuccinate (FDA substance registry), polyoxyl 40 stearate is PEG-40 stearate, and the 4%’s single “carbomer” is coded on its label as the same two carbomers the 10% names (DailyMed). Matched up, the 4% lists the 10%’s 20 ingredients plus sorbitol, a humectant. Both lists are alphabetical, so the amounts of each can still differ.

PanOxyl 10% Foaming Wash and 4% Creamy Wash, label against label

Label fact	PanOxyl Acne Foaming Wash	PanOxyl Acne Creamy Wash

Does 10% work better? We found no trial showing it does. In the classic comparison, three double-blind studies of leave-on gels in 153 people, 2.5% matched 5% and 10% on inflammatory acne and caused less irritation than 10% (Mills, 1986). A 2020 Cochrane review of 120 trials called for more studies comparing strengths (Yang, 2020). The one point for 10% in a wash: in a lab dish, 10% and 5% killed acne bacteria within 30 seconds, while 2.5% took 15 minutes (Boonchaya, 2022), which may matter when the wash is rinsed off in minutes. That has not been tested on skin.

Which should you buy? For your face, especially if you are new to benzoyl peroxide, the 4%, as PanOxyl itself advises (PanOxyl). For the chest and back, or a face that already tolerates benzoyl peroxide, the 10%. On Reddit, 8 of the 12 commenters we read who compared strengths favored a strength below 10%, several because the 10% dried them out.

PanOxyl vs CeraVe Acne Foaming Cream Cleanser

CeraVe’s benzoyl peroxide wash is the best overall pick in our acne face wash guide. It takes the opposite approach: a lower strength with barrier ingredients added.

PanOxyl 10% and CeraVe 4% benzoyl peroxide washes, label against label

Label fact	PanOxyl Acne Foaming Wash	CeraVe Acne Foaming Cream Cleanser
Benzoyl peroxide	10% benzoyl peroxide	4% benzoyl peroxide
Inactive ingredients	21, in alphabetical order	27, not alphabetical
Ceramides, niacinamide, hyaluronic acid	None listed	Three ceramides, niacinamide, sodium hyaluronate
Glycolic acid	Not listed	Listed, 13th of 27
Contact time on the label	Massage 1 to 2 minutes, then rinse	None given: massage, then rinse
In our acne wash guide	Best 10% wash, for face and body	Best overall
Added fragrance	None listed	None listed
Where to buy	Check price at Amazon: PanOxyl Acne Foaming Wash (paid link, opens in a new tab)	Check price at Amazon: CeraVe Acne Foaming Cream Cleanser (paid link, opens in a new tab)

Both lists are read from the US Drug Facts on DailyMed (PanOxyl, CeraVe). CeraVe’s list is not alphabetical and PanOxyl’s is, so a place on one list cannot be compared with a place on the other. We found no trial that compares the two.

Which should you buy? For a face that is new to benzoyl peroxide or prone to dryness, CeraVe. For body acne or oily skin that tolerates benzoyl peroxide, PanOxyl.

Is it the same PanOxyl as before? Not since 2017

PanOxyl began at Stiefel Laboratories, which first used the name in 1972 (USPTO). GSK bought Stiefel in 2009 (GSK), and Crown Laboratories bought the North American rights in November 2018 (Crown, 2018). The label history, version by version:

• Until late 2017, a different wash. Stiefel’s 10% foaming wash listed methylparaben, imidurea, sodium lauryl sulfate, mineral oil, and glycolic and lactic acid (DailyMed, 2016). Some store pages still show that list (example).
• November 2017: “New Formula”. Under GSK, the tube gained a New Formula banner and today’s base: carbomer, decyl glucoside, t-butyl alcohol and the rest (DailyMed, 2017). A year earlier, GSK had tested two new 4% and 10% washes against the PanOxyl 10% then on sale (GSK study 206239); we could not confirm that the tested 10% is the one sold today.
• 2018: Crown’s labels. The same base, now in pharmacy names (DailyMed, 2018).
• 2024 and 2025: small list changes. In July 2024 the printed list switched to “Aqua”, gained oleic acid and dropped t-butyl alcohol; the November 2025 carton put t-butyl alcohol back (DailyMed, 2024, 2025). Crown has not said whether these were formula changes.

Does PanOxyl work? What the studies show

• Benzoyl peroxide, yes. The AAD’s 2024 guidelines make a strong recommendation for it (Reynolds, 2024; several authors report industry ties). A 2020 Cochrane review of 120 trials found it beat placebo on people’s own ratings, with low-certainty evidence; 50 of the trials were paid for by industry and 63 did not say (Yang, 2020).
• Washes, less clear. A 2018 review found too few well-done studies of washes and cleansers to make reliable recommendations (Stringer, 2018). In one small 1989 crossover, a 10% benzoyl peroxide wash did not significantly reduce blackheads and whiteheads, while a 2% salicylic acid cleanser did (Shalita, 1989). Contact time matters on the back, as above.
• PanOxyl’s washes: irritation only. The one study we found that used a PanOxyl wash was GSK’s, run in 2016 and 2017 while GSK owned PanOxyl: 133 people used two new 4% and 10% washes or the PanOxyl 10% Foaming Wash then on sale (the formula before today’s) twice a day for 21 days, massaged in for 1 to 2 minutes, and irritation scores barely changed in any group (GSK, Santos-Caetano, 2019). It did not measure acne, and we could not confirm that either new wash is the one sold today. We found no trial of this wash’s effect on acne.
• The “99% in 15 seconds” claim rests on an unpublished “Independent Laboratory Study, Data on File” (PanOxyl).

Bottom line: it delivers an acne ingredient the AAD strongly recommends, at the highest strength sold without a prescription, but we found no trial of this wash on acne and no proof that 10% beats a lower strength.

PanOxyl and benzene: what is known

Benzene, a carcinogen, is not an ingredient, but it can form as benzoyl peroxide breaks down, more so with heat. What we found about this wash:

• It was in Valisure’s heat test. In March 2024 the testing lab Valisure asked the FDA to act on benzene in benzoyl peroxide products. Its 18-day test at 50 °C (122 °F) includes a “10.0% PanOxyl Cream” with this wash’s UPC, 303160228551. Its chart shows that wash’s benzene rising past 150 parts per million within 14 days; many of the 66 products heated rose too, some far higher. Valisure printed no table of values and no lot number (Valisure); its own published study, paid for by Valisure, tested other brands (Kucera, 2024). The FDA says a drug batch should not be released with more than 2 ppm of benzene (FDA), and it has not ruled on the petition (FDA, 2024).
• It was not recalled. The FDA tested 95 benzoyl peroxide products itself, found more than 90% had undetectable or extremely low benzene, and six were voluntarily recalled at the retail level; PanOxyl was not among them, though the FDA did not publish the full list (FDA, 2025). We found no PanOxyl recall in the FDA’s recall data through September 2026 (openFDA).
• Washes ran higher than leave-ons in an analysis of 111 products that Valisure tested at room temperature (PanOxyl was not among them), while strength made no difference (Barbieri, 2025).
• No cancer signal so far in a large study of people prescribed benzoyl peroxide, though it did not capture store-bought use (Garate, 2024).
• A lawsuit is pending. A proposed consumer class action over benzene in PanOxyl products has been in federal court in California since 2024; its claims are unproven, and in August 2025 the court said it was inclined to dismiss the case but allowed an amended complaint (docket). We found no statement on benzene from PanOxyl.

What to do: the AAD advises storing benzoyl peroxide products at room temperature or cooler, replacing them every 10 to 12 weeks, and throwing out any left in heat above about 78 °F (AAD, AAD statement); a hot car counts. The label itself says to store it at 68 to 77 °F. If you would rather avoid benzoyl peroxide, our salicylic acid cleanser picks are the usual alternative.

What the label can’t tell you

• How much of any inactive ingredient there is. The list is alphabetical.
• Whether the 2024 list changes were a new formula. Crown has not said.
• How much benzene your tube holds. That depends on its age and how it was stored, which no label shows.
• How it will feel on your skin. We did not test it on skin. What people who used it say is below.

PanOxyl Acne Foaming Wash reviews on Reddit

PanOxyl is everywhere on Reddit: r/acne alone has 5,621 comments that name it, from 2012 to October 2026, and most do not say which strength. We read every comment in 8 threads about experiences with PanOxyl and scored each personal verdict: 71 of 112 said it worked, 12 were mixed and 29 said it did not work or they stopped; 7 more were in their first weeks. One thread was chosen because it asked whether to keep going. Opinions are not evidence, but they show what to expect:

• Most do not say which PanOxyl. Only 18 of the 112 named the 10% alone; 13 of those said it worked, 4 were mixed and 1 did not. Another 16 named a 4% PanOxyl, mostly the Creamy Wash, and 2 had tried both; the poster of one thread asking whether PanOxyl works was using the 4% (2025 thread).
• Body yes, face sometimes. Of 23 verdicts that mention the body, 15 said it worked; 6 of those 7 mixed verdicts said it was good on the body but too harsh, or no help, on the face. “I love it for body acne but man does it bleach the hell out of my clothes” (2024 thread).
• Dryness, and around the eyes. 18 verdicts mention dryness or peeling, and 5 users say it did not dry them out. One wrote: “It just really dries my skin out around my eyes so I have to only use it a few times a week now” (2023 thread).
• Contact time is all over the place. 19 users give a time, from “i just wash my face for 60 seconds then rinse it off” (2021 thread) to “I aim for 10 minutes before rinsing” (2025 thread).
• Allergic reactions, rare but real. 4 people stopped after what they called an allergic reaction, 3 of them describing swelling or itching: “I had an allergic reaction to this. My face became itchy and red and swollen” (2021 thread).
• Patience. Reported times to results run from days to months: “I didn’t see huge results until month 3 or 4 though” (2023 thread). And some never saw any: “I was recommended it by two different derms and was utterly disappointed” (same thread).
• The 4% for faces. 8 of the 12 who compared strengths favored a strength below 10%: “I would’ve gotten the 4% cause it doesn’t dry out your face so much” (same thread).
• Body odor. Outside the acne subreddits, r/Hygiene uses PanOxyl for underarm odor; its PanOxyl comments jumped from 28 in 2023 to 242 in the first half of 2024, and its most-upvoted PanOxyl post is about PanOxyl’s bar soap (thread).

How to use PanOxyl Acne Foaming Wash

1. Patch-test first. Use it on one or two small areas for 3 days, as the FDA suggests after rare but serious allergic reactions to OTC acne products (FDA).
2. Wet the skin, massage it in for 1 to 2 minutes, rinse thoroughly and pat dry, as the label says. On the back, the AAD suggests 2 to 5 minutes before rinsing.
3. Once a day at first, going up to 2 or 3 times a day only if needed; if dryness or peeling bothers you, cut back to once a day or every other day.
4. Moisturize after with a plain, fragrance-free moisturizer, and in the morning wear sunscreen: the label says to apply it after the wash if you go outside.
5. Keep it away from your eyes, lips, mouth and hairline, and use white towels and pillowcases: it bleaches hair and dyed fabric.
6. One acne medication at a time if your skin gets irritated, as the label says. With tretinoin, the simplest plan is the wash in the morning and tretinoin at night.
7. Store it cool: the label says 68 to 77 °F, so not in a hot car or on a sunny windowsill. Replace it every 10 to 12 weeks, as the AAD advises for benzoyl peroxide.
8. Give it 4 to 6 weeks before judging it (AAD), and see a dermatologist if your acne is deep or painful (AAD). If irritation becomes severe, stop and ask a doctor, as the label says.
