As someone who’s constantly on the lookout for skincare products that actually deliver results, especially for acne, I was immediately intrigued when I came across the 111MedCo 10% Benzoyl Peroxide Acne Soap Bar. At 10%, it has the highest concentration of benzoyl peroxide available over-the-counter, and that made me hopeful but also a little cautious. Would it be too harsh? Would it dry my skin out? I decided to give it a try and find out for myself.

Packaging

The first thing I noticed was how minimalist the packaging is. It’s a recyclable cardboard box with a clean design—white and orange with bold black text. There’s nothing flashy here, but it’s very clear that the product is positioned as a no-nonsense, medicated solution rather than a beauty soap. I appreciate the straightforwardness.

What also stood out to me is the environmental angle. The company deliberately uses recyclable cardboard packaging to avoid plastic waste, which I find thoughtful and responsible. The soap bar itself is a smooth, white oval that fits comfortably in the hand, and the simple embossing adds a functional elegance. It’s the kind of product that tells you up front: “I’m here to work.”

Ingredients

This bar is clearly designed with purpose. The main active ingredient is 10% benzoyl peroxide, a synthetic but potent antibacterial and exfoliating agent that’s known for treating acne at the source. It’s accompanied by a short list of inactive ingredients like glycerin (which helps with dryness), cetearyl alcohol, and sodium cocoyl isethionate.

What’s impressive is what it doesn’t include—no parabens, no dyes, no fragrance, no lanolin. That’s a big deal for sensitive skin like mine. Plus, it has a pH level between 6.0 and 6.5, close to the skin’s natural balance, which helps minimize irritation. It’s not marketed as hypoallergenic, but with such a clean formula, it comes pretty close.

Scent

This soap is marketed as fragrance-free, and that’s mostly accurate. There’s no added perfume, which I appreciate, but there is a faint clinical or medicinal smell. It’s subtle and not at all lingering—it just smells “clean.” To me, that’s a plus. Fragrances often irritate my skin, so this was a welcome change from other acne products that try to mask their scent with overpowering floral or citrus notes.

Lather and Application

Despite being a medicated soap, the lather is rich and creamy. It foams up almost instantly when I add a little water and rub it between my palms. The creamy lather spreads easily and offers a good amount of slip, which makes it easy to cover larger areas like the shoulders or chest without using a ton of product.

The instructions recommend starting with once-daily use, which I followed. It rinses off thoroughly, leaving behind a squeaky-clean feeling without a sticky residue. However, I learned the hard way that benzoyl peroxide can bleach fabrics—towels, pillowcases, even t-shirts. I’ve since switched to using white fabrics after application.

Effectiveness

This is where the soap really earns its reputation. Within the first two weeks, I noticed a reduction in active breakouts. Even the painful cystic acne around my chin began to calm down. It’s also been helpful on my back and shoulders, areas where I’ve always struggled with stubborn breakouts.

That said, it wasn’t all smooth sailing. I experienced a bit of an initial “purging phase”—my skin broke out slightly more as it adjusted. I later read this is common with strong actives like benzoyl peroxide because they increase cell turnover and push impurities to the surface. Thankfully, this subsided after about 3 weeks.

For those with sensitive skin, the soap can be intense. Some users recommend the “short contact therapy” method—leaving it on for 30 to 60 seconds before rinsing. I tried this on days my skin felt extra dry, and it did help ease the intensity without losing too much effectiveness.

Size and Lifespan

At 4 ounces (113 grams), the bar is fairly standard in size but lasts surprisingly long. It’s a hard-milled soap, which means it doesn’t melt away quickly in the shower. I store it in a draining dish, and even with daily use, one bar lasted me over a month.

There’s no travel-sized version currently, which would be convenient for on-the-go, but this isn’t a dealbreaker for me. What matters more is how effective and economical it is. A little truly goes a long way.

Brand Reputation

I hadn’t heard of 111MedCo before, but after some digging, I found that they’re a small, family-run business based in the USA. Their approach is rooted in creating science-backed, no-frills medicated skincare, and they focus primarily on therapeutic cleansing bars.

Their products are made in FDA-registered and GMP-compliant facilities, and they’re cruelty-free, which is something I personally look for in every skincare brand I support. They don’t have a big social media presence, but they make up for it with transparency and responsiveness. I sent them an email with a question about product storage and got a helpful reply within 24 hours.

Price and Value

At around $7 to $10 per bar, this product offers serious bang for your buck. The high concentration of active ingredient, long-lasting formula, and minimalistic but effective composition make it a solid value. Compared to pricey acne treatments and serums, this bar holds its own.

And unlike some products that feel like you’re paying for the branding more than the results, here you’re paying for performance and integrity. I’ve also seen occasional discounts on online platforms like Amazon, so it’s worth keeping an eye out.

Availability

One downside is that it’s not widely available in physical stores. You won’t find it on shelves at your local pharmacy. However, it’s consistently available online, particularly on Amazon and Walmart’s website, and most listings offer fast shipping.

Bulk purchase options are sometimes available online, which is a nice way to save a bit if you’re planning to stick with it long-term—as I now plan to.

Overall Rating

If I had to give this soap a rating, it would be a solid 8.4 out of 10. It works, plain and simple. The only reason I’m holding back on a full 5 stars is because of the initial adjustment period and the care you have to take to avoid bleaching towels.

But as far as acne products go, this is one of the most effective, no-frills solutions I’ve ever tried.

Tips & Recommendations

Honestly, this bar has become a staple in my skincare routine, and I plan to keep it that way. If you’re dealing with persistent acne and are ready for something powerful yet uncomplicated, I’d say give it a go.
