Sulfur has been treating skin since before dermatology had a name, and it survived because it does two things at once. It’s keratolytic, meaning it softens the plug inside a pore and helps shed it, and it’s antimicrobial against the yeast and bacteria that turn a clogged pore into a red bump. That combination is unusual. Most actives pick one job.
Where it earns its place is the ground benzoyl peroxide and salicylic acid keep losing. Fungal acne, those uniform itchy papules along the hairline and chest. Rosacea-adjacent papulopustular skin that flares the moment you reach for peroxide. Our editors compared full ingredient lists, cross-referenced the dermatology literature on sulfur concentrations, and read through aggregated verified-buyer feedback looking for repeated complaints instead of single bad days. You’ll find other options in our roundup of the best cleanser for general use, but the five below earned their spots specifically on sulfur.
Quick answer: Kate Somerville EradiKate is the pick if you want the 3% sulfur sweet spot in a daily wash, with Prequel for redness-prone skin, Proactiv for sensitive daily use, AcneFree for oily budget shoppers, and Healov if you want a face-and-body bar for chest and back.

How We Evaluated These Sulfur Cleansers
Where sulfur sits in an ingredient list tells you almost everything. In a medicated wash it belongs in the Active Ingredients box at the top, with a percentage attached, because the FDA monograph requires it. If sulfur only shows up two-thirds of the way down the inactive list, next to the fragrance and the colorant, it’s decoration. That single check eliminated a surprising number of products marketed as sulfur cleansers. OTC strength runs 3% to 10%, and 3% is the sweet spot in a wash, since a rinse-off product has a minute of contact and the higher percentages mostly buy you more dryness.
After that filter, we compared surfactant systems, because a harsh cleansing base undoes whatever the sulfur accomplishes on already-compromised skin. We cross-referenced research on sulfur’s activity against malassezia and its role alongside sodium sulfacetamide 10%, the classic prescription-adjacent pairing for rosacea and acne. Verified-buyer feedback was weighted for patterns, not outliers. Everything here has to be in stock, honestly labeled, and priced reasonably per use.
Kate Somerville EradiKate 3% Sulfur Daily Foaming Cleanser — Best overall
Three percent sulfur, declared as an active, in a foaming base built for daily use. That’s the specification you want and surprisingly few brands commit to it. What makes this one work is restraint. The sulfur is high enough to be keratolytic without pushing you into the flaking that 8% and 10% products cause by week two, and the foam rinses clean rather than leaving that squeaky stripped feeling. It’s the one I’d hand someone whose dermatologist mentioned sulfur but who isn’t ready for a prescription sulfacetamide wash. The catch is cost per wash, which is real. And the fragrance used to mask the smell is noticeable, so patch it first if you flush easily.
Prequel Skin Redness Reform Sulfur Cleanser — Best for redness and rosacea-prone skin
This is the one aimed squarely at sulfur’s best use case. Papulopustular rosacea, the kind with actual bumps and not just flushing, responds to sulfur in a way it rarely does to benzoyl peroxide, which tends to inflame that skin further. Prequel built the formula around calming support rather than maximum strip, so the surfactants stay mild and the foam is loose instead of dense. Redness-prone skin usually needs a wash that leaves something behind. Worth knowing: it’s slower than a peroxide wash on a single angry pustule, so don’t expect overnight. Buy it for the six-week trajectory, not the emergency.
Proactiv Clean Mineral Acne Cleanser — Best for sensitive daily use
Proactiv is a brand most people associate with benzoyl peroxide, so a sulfur wash from them is a genuine departure, and a smart one. The mineral positioning here means a creamier, lower-foam base, which matters because the people who most need sulfur are often the people who can’t tolerate a high-foam gel every morning. Use it as your morning cleanse and keep something blander at night. That’s the routine that works. The trade-off is that a creamy base holds sulfur against skin less efficiently than a foam, so results build slowly, and the masking fragrance is present.
AcneFree Sulfur Acne Foaming Cleanser — Best budget pick for oily skin
Sulfur plus lemon oil plus oat extract reads like a compromise, and it partly is, but the sulfur is properly declared and the foaming base suits genuinely oily skin better than the cream formulas here. If your T-zone reloads by lunch and you want the sulfur mechanism without a specialty price, this is the sensible entry point. Pair it with our notes on the best cleanser for oily skin if oil control is the bigger issue. Caveat: lemon oil is a fragrance-family ingredient, and rosacea-prone or reactive skin should look at Prequel or Proactiv instead. This one’s for oily and tolerant.
Healov Sulfur Soap Face and Body Wash — Best for chest, back, and body
Fungal acne rarely stays on the face. It clusters on the chest, the upper back, the shoulders, and that’s exactly where a bar or body-scale sulfur wash makes more sense than decanting a facial cleanser. Healov leans exfoliating and oil-absorbing, which is fine on body skin and too much for most faces used daily. So treat the “face and body” label as optional on the face. Short-contact use is the trick here, and the honest downside is the smell, which is stronger in bar-style sulfur products than in the masked foaming ones. Rinse thoroughly.
What to Look For in a Sulfur Cleanser
Concentration, and where it’s declared. Look for 3% to 10% sulfur listed as an active ingredient with the percentage printed. Three percent in a wash is the sweet spot. Ten percent isn’t twice as effective in a rinse-off product, it’s just twice as drying, and dryness is what makes people quit sulfur in week three. If no percentage appears anywhere on the label, assume there isn’t enough to matter.
The masking system, and its cost. Sulfur smells like eggs. Formulators cover it with fragrance, and fragrance is one of the more common irritants for exactly the rosacea-prone people who need sulfur most. That tension is unavoidable and worth naming out loud. If you flush easily, choose the least-perfumed option you can tolerate and accept a faint sulfur note as the price of a calmer face.
What it pairs with, and what it doesn’t. Sulfur is drying, so a bland moisturiser isn’t optional. Don’t stack it with benzoyl peroxide or a retinoid on the same night while you’re starting out. Use short contact: lather, leave it 30 to 60 seconds, rinse. Most of the benefit, much less of the dryness. Our guide to a gentle cleanser for retinol covers the alternate-night approach.
Frequently Asked Questions
Does sulfur work on fungal acne when benzoyl peroxide doesn’t?
Often, yes, and that’s the main reason to reach for it. Malassezia folliculitis is a yeast overgrowth, not bacterial acne, so benzoyl peroxide and salicylic acid frequently underperform on it. Sulfur has antifungal as well as antibacterial activity, which is why dermatologists still use it for those uniform itchy bumps on the chest, back, and hairline.
Is sulfur safe to use during pregnancy?
Sulfur is one of the few acne actives generally considered pregnancy-compatible, alongside azelaic acid, which is why searches for it spike among people who’ve just stopped a retinoid. That said, this isn’t a decision to make from an article. Bring the actual product label to your obstetrician or dermatologist and let them clear it.
Will a sulfur cleanser clear blackheads?
Not really, and that’s the honest answer. Sulfur softens and sheds plugs to a degree, but comedonal acne, meaning blackheads and whiteheads without much inflammation, is a retinoid’s job. Sulfur’s strength is inflamed papules and pustules and fungal folliculitis. If your main complaint is texture and clogged pores, start with a retinoid instead.
Can I use a sulfur wash and benzoyl peroxide in the same routine?
You can eventually, but not while you’re starting out. Both are drying and both work on the same inflamed lesions, so stacking them mostly buys you a compromised barrier. Alternate mornings and evenings, or alternate days. If you’re using a retinoid too, keep the sulfur to mornings and give your skin one bland night a week.
What’s the difference between sulfur and sodium sulfacetamide washes?
Sodium sulfacetamide 10% is an antibacterial sulfonamide, and it’s usually combined with 5% sulfur in prescription or prescription-adjacent washes for rosacea and acne. That combination is the stronger version. Sulfur-only OTC cleansers like the ones here are the accessible equivalent, milder and available without a visit, and often enough on their own.
Bottom Line
Sulfur isn’t the strongest acne active on the shelf and it never was. It’s the most useful one in a specific place: fungal folliculitis, papulopustular rosacea, and anyone who needs an option that isn’t benzoyl peroxide. Kate Somerville EradiKate is the pick for most people because 3% in a daily foaming wash is the concentration that actually holds up. Prequel suits redness-prone skin, Proactiv works for sensitive morning use, AcneFree covers oily skin on a budget, and Healov handles chest and back. Start with short contact and a plain moisturiser, and give it six weeks.
