ABOUT THIS PRODUCT
Individual results may vary.
A targeted acne treatment in the form you already know — bar soap.
DermaHarmony 10% Sulfur Bar Soap is an over-the-counter acne medication formulated with the maximum monograph-permitted concentration of sulfur (10%). Sulfur is generally recognized as safe and effective (GRASE) by the FDA for the treatment of acne.
This acne bar soap penetrates pores to reduce the number of acne blemishes, acne pimples, blackheads, and whiteheads — and allows skin to heal. With consistent daily use, it helps prevent new acne blemishes from forming. Thousands of customers use DermaHarmony sulfur soap as an affordable OTC acne treatment — with a cleaner ingredient list, no parabens, and no fragrance.
Why sulfur?
Sulfur has been used in skincare for centuries. As an acne treatment, it works by helping to dry and clear acne blemishes while being gentle enough for sensitive skin and daily use on both the face and body. Unlike some acne treatments that can be harsh or irritating, sulfur-based soaps are well-suited for people who want effective pore-level cleansing in a simple, rinse-off routine.
Many people find sulfur to be a better fit for their skin than benzoyl peroxide, which can bleach fabrics and cause more pronounced dryness or irritation. Sulfur offers a gentler approach for those with reactive or easily irritated skin.
What Makes This Bar Different?
- Maximum OTC strength. 10% sulfur — the highest concentration permitted under the FDA acne drug monograph. You will not find a stronger sulfur acne soap over the counter.
- Clean, minimal formula. No parabens, no fragrances, no dyes, no sulfates. Just seven inactive ingredients. We kept the formula as clean as possible.
- Gentle enough for sensitive skin. This bar is noncomedogenic and hypoallergenic — designed not to clog pores or provoke unnecessary irritation. Customers consistently report that it works without the harsh drying or stinging that other acne treatments can cause.
- Works everywhere acne shows up. Face, back, chest, shoulders — this body acne soap works anywhere you have acne blemishes.
- Rich, effective lather. The bar produces a creamy lather that spreads easily and rinses clean. A little goes a long way.
- Long-lasting bar. Each 4 oz bar typically lasts four to six weeks with daily use — a fraction of the cost of prescription sulfur washes.
- Safe for adults and children. Suitable for daily use by the whole household.
- Made in the USA. Every bar is manufactured domestically and individually cartoned or wrapped.
Who It's For?
This sulfur acne soap is a good fit if you:
- Have mild to moderate acne — pimples, blackheads, whiteheads, or blemishes on the face or body
- Want an OTC acne medication with maximum-strength sulfur
- Are looking for a paraben-free, fragrance-free acne soap with a short ingredient list
- Have sensitive skin that reacts poorly to benzoyl peroxide or other harsh acne treatments and medications
- Deal with back acne, chest acne, or shoulder breakouts and want a soap that does double duty
- Are switching from a prescription sulfur wash and want an OTC sulfur acne soap that doesn't require a prescription
- Prefer a straightforward cleansing routine — no multi-step regimens required
How Sulfur Compares to Other Acne Ingredients
Not sure whether sulfur is the right acne-fighting ingredient for your skin? Here's a quick comparison.
Sulfur vs. Benzoyl Peroxide
Benzoyl peroxide is widely used for moderate to severe inflammatory acne. It can be very effective but is also known for bleaching towels and clothing, and for causing significant dryness, redness, and peeling — especially in people with sensitive skin. Sulfur takes a gentler approach. It dries and clears acne blemishes without the bleaching risk, and many people with sensitive or reactive skin find it easier to tolerate.
Sulfur vs. Salicylic Acid
Salicylic acid is a popular choice for blackheads and whiteheads. It works by exfoliating inside the pore. Sulfur also helps clear pores, but with added drying action on excess oil. Some people use both — DermaHarmony also makes a Sulfur & Salicylic Acid Bar Soap for those who want both ingredients in a single bar.
Both benzoyl peroxide and salicylic acid can be effective. The right choice depends on your skin type, sensitivity, and the type of acne you're dealing with. If you've found other treatments too harsh, sulfur is often worth trying.
A Note on the Scent
Sulfur has a distinctive natural smell — there's no way around it. That said, the overwhelming majority of our customers describe this bar's scent as mild, bearable, and far less intense than prescription sulfur washes or other sulfur soaps on the market. The smell does not typically linger on skin after rinsing, especially once you apply moisturizer or your other daily products. A small number of people are more sensitive to the scent — if you're concerned, start by using the bar on a small area to see how the smell sits with you.
A Note on Dryness
Sulfur is a drying ingredient by nature — that's part of how it works to clear acne blemishes. Most customers find this bar drying but manageable, especially when followed with a good moisturizer. We recommend starting with one application per day and increasing frequency gradually. If you experience bothersome dryness, scale back to every other day. The key is to always follow up with a moisturizer that works for your skin.

DIRECTIONS
For best results, use daily — or as directed by your doctor.
- Wet your skin with warm water.
- Work the bar into a lather and gently massage onto affected areas.
- Leave the lather in contact with skin for at least 30 seconds.
- Rinse thoroughly.
Use on affected skin in place of your regular soap.
Getting started: Because some users experience dryness when beginning a sulfur acne soap, start with one application per day and gradually increase frequency. You may increase to two or three times daily if needed, or as directed by a doctor. If bothersome dryness or peeling occurs, reduce application to once a day or every other day. Follow cleansing with the moisturizer of your choosing.
Sensitivity test for new users: Apply the product sparingly to one or two small affected areas during the first 3 days. If no discomfort occurs, follow the directions above.
WARNINGS
For external use only.
Do not use on:
- Broken skin
- Large areas of the skin
When using this product:
- Apply only to areas with acne.
- Skin irritation and dryness is more likely to occur if you use another topical acne medication at the same time. If irritation occurs, only use one topical acne medication at a time.
Stop use and ask a doctor if skin irritation occurs or gets worse.
Keep out of reach of children. If swallowed, get medical help or contact a Poison Control Center right away. In case of accidental ingestion, contact a physician or Poison Control Center immediately.
Additional note: Sulfur will tarnish (blacken) silver jewelry. Remove silver rings, bracelets, and necklaces before use.

excellent
This soap is a good quality bar that suds very well and seems to have a good percentage of sulfur in it. It helps clear up my rosacea and makes it less noticeable.
The sulfur bar soap helped the problem I was having with breakouts on and around my nose after consistent use over 2 weeks. It hardly has any scent, rinses off easily and doesn’t dry my skin out. I would definitely recommend.
Works as it should
Great soap
Good purchase
It smells like sulfur however it’s not overwhelming like my old prescription sulfur wash I used to use. I switched from a pharmacy sulfur wash because it had parabens in it. This has worked well as far as I can tell. I don’t have many break outs ever. It dries out my skin if I keep the product on my face too long or wash too often so you just need to be careful with how often and how vigorously you wash your face with it. As for my chest and back the soap never dries out my skin there. The soap lasts me a little over a month which is great. It’s cheaper than my old prescription sulfur wash, just about as effective and lasts as long as my old prescription soap lasted. Although I can’t say it helps with black heads so you may have to use a separate product to address that. Otherwise it’s a great alternative to prescription strength sulfur wash and works good.
Regulatory Note: We do not sanction direct 'alternative to prescription' framing, which could be flagged by the FDA under the 'products that imply they are as effective as prescription drugs' rule. No such claims are marketed by DermaHarmony.
Smells good, great antibacterial, not drying, good price!
Good purchase.
I got this to help with rosacia, the Rx isn't covered by my insurance. This is good, it helps, and I use it as a whole body soap. It doesn't smell and had some grit to help exfoliate. Good value and I'll buy it again!
My new favorite bar soap for the face. Also works great underarms to remove BO. This bar soap is incredible. I didn't expect it. My face looks healthy and shiny (not oily). Odd little bumps I had on my forehead, nose area, and earlobes have all but gone and shrinked immensely since using this. I use it twice a day. Morning and after the gym. Lightly massage it on and then leave for 2-4 mins before rinsing - I feel like this is the most important step - draws out all the impurities. Only con is the scent definitely takes some getting used to
If you're looking for sulfur soap, this is the best option. Some stink terribly. This is odorless and has a nice, smooth texture.
Prescribed by my doctor
My land is infested with chiggers. I use the soap to wash my chigger bites when I accidentally wore shorts. Bites dries up quicker when I wash it with this sulfur bar of soap.
I didn't like th smell. It mght work for others. I just cannot use because I don't like the smell of sulfur.
Fast shipping and very happy with the soap. Works like it says.
Extremely drying but works well. Be sure to use a good moisturizer after washing. Does not smell bad.
I've been using this soap for the last two years. Love it. Works well on my sensitve skin. A bar lasts me about 6 weeks washing daily. It's a natural product and very affordable.
My skin is soft after using dermaharmony soap. It smells like sulfur but that's okay considering that my white heads are gone and my skin is 90% better.
Dermaharmony is hands down the best sulfur soap that you can get. It has helped my condition so much. Can be a little drying if your skin is not super oily. I've used a few brands of sulfur soap and this one is by far the best.
It works really well and does not stink that gad. Cleared most of my acne in about 10 days.
This is my first time trying this soap and I will say it is not over drying and I see no bad side effects. My skin looks and feels healthier.
Excellent soap if you wear tight gym clothing regularly. I noticed I was losing pigment in my skin and eventually was told I had tinea versicolor from wicking activewear I wore at the gym, despite jumping in the shower 5 minutes after every workout. Guess it can just happen. I have sensitive skin and havent had any issues with this soap, including my face which is incredibly rare.
Do you ever feel like your deodorant is failing you? Just wash your pits with this. Also works on cracks and junk. Gentle. Rinse it off and there is no odor. Better than benzoyl peroxide because it doesn’t bleach and kills bacteria and doesn’t dry out your skin. Also helps any buttne or backne you may have. Haven’t tried it on my face yet but my husband used it on his shaving irritation and asked me to buy another bar
I bought it after sulfur soap (10%) was recommended for Perioral Dermatitis. It helped to clear it up after several items I tried didn’t work. I use it once a day.
Very good soap! Would purchase again.
It’s great definitely my face isn’t as red definitely recommend!!
I’ve tried so many things and this is the only thing that has worked ! Thank you for fast shipping also.
I have gotten amazing results with this soap, ordering more...Thank you for making such an excellent soap..
Don't waste money and time ordering elsewhere. Dermaharmony is lit, dope, sick, fire, dank. Epic at eliminating ACNE.
I have super oily skin and this soap helps to control all the bad stuff that the oil brings. Use it every morning and evening. Keeps my skin dry and spot free.
Doctor told me to get this brand. Saw 100% improvement in a few days. Love it.
My Tinea Versicolor go to. My case is mild. This bar soap does the trick.
Butt acne gone. I'll repurchase when I run out.
