If you’ve ever stared at a bar of exfoliating soap on a shelf, wondering why some leave your skin feeling soft and smooth while others feel like they’re scratching at your face, you’re not alone. As a soap supplier who’s spent the last 12 years formulating and testing every batch that leaves our warehouse, I get dozens of emails a week from customers asking the same question: what’s actually in that stuff that sloughs off dead skin? It’s not just random grains mixed in with regular soap—every ingredient in exfoliating soap serves a specific purpose, and getting that balance wrong can turn a gentle treatment into something irritating. Let me break down what goes into our exfoliating bars, why we choose certain ingredients over others, and how you can spot a quality product from a mile away. Soap
First, let’s start with the base of the soap itself—because no exfoliant works if the underlying soap is harsh. A lot of cheap exfoliating soaps on the market use sodium lauryl sulfate (SLS) as their primary cleanser, a foaming agent that’s super effective at stripping dirt but also strips your skin’s natural lipid barrier. Over time, that leads to dryness, redness, and even sensitivity, especially if you’re using it on a regular basis. That’s why at our company, we use a milder soap base: a combination of saponified organic coconut oil, olive oil, and shea butter. Saponification is just the process of turning fats into soap, and when done right, it creates a gentle, conditioning base that doesn’t leave your skin tight. The coconut oil gives us a rich, creamy lather that feels satisfying in the shower, the olive oil adds antioxidants to protect your skin, and the shea butter locks in moisture so the exfoliant works with your skin, not against it. We also skip artificial fragrances in our base—instead, we use natural essential oils like lavender or tea tree for scent and extra skincare benefits, which is a big part of why our customers tell us our soap doesn’t irritate their sensitive skin.
Now, the star of the show: the exfoliants. This is where most suppliers cut corners, and it’s where we’ve spent years perfecting our blends. Exfoliants fall into two main categories: physical and chemical, and we almost always combine both for the best results. Physical exfoliants are the tiny, gritty particles you can see in the soap, and their whole job is to physically slough off dead skin cells from the surface. But not all grit is equal. We never use plastic microbeads—those are banned in the U.S. and many other countries because they don’t biodegrade and end up in oceans, harming marine life. Instead, we use natural, biodegradable exfoliants. The most common one we use is jojoba beads? No, wait—jojoba beads are actually made from jojoba oil, not plastic, and they’re super soft, which is great for gentle exfoliation. But for a deeper clean, we use ground walnut shells. Wait, but we make sure the walnut shells are finely milled—if they’re too big, they can scratch your skin. We test every batch under a microscope to make sure the particle size is between 100 and 200 microns; that’s the sweet spot where they’re abrasive enough to remove dead skin but not so sharp that they damage the skin’s surface. We also add ground oatmeal to a lot of our exfoliating bars—oatmeal has anti-inflammatory properties that soothe irritated skin, and its fine texture is perfect for areas like the face, where you want something gentler than the body exfoliants.
Then there are the chemical exfoliants, which are the unsung heroes that work below the surface to dissolve dead skin cells that are stuck to your skin, even after a physical scrub. A lot of people think exfoliation is just about scrubbing, but chemical exfoliants help unclog pores and improve skin texture over time, which is why we include them in our soap. The most common ones we use are alpha hydroxy acids (AHAs) like lactic acid, which is derived from milk, and beta hydroxy acids (BHAs) like salicylic acid, which comes from willow bark. Lactic acid is great for gentle exfoliation on the face—it’s smaller than other AHAs, so it penetrates the skin more effectively, and it also adds moisture to your skin. Salicylic acid is oil-soluble, which means it can get into your pores to dissolve excess sebum and blackheads, making it perfect for body soaps for people with acne-prone skin. We don’t use strong chemical exfoliants like glycolic acid in our regular exfoliating soap because they can be too harsh for daily use—we stick to concentrations between 1% and 2% of these acids, which is safe and effective for most skin types when used as directed.
Wait, let me clarify something: a lot of people confuse exfoliating soap with body scrubs. Body scrubs are usually a separate product you apply and rinse off, often with a lot of oil to make the grit glide, but exfoliating soap is a bar, so the exfoliants have to be evenly distributed throughout the soap base. That means we have to make sure the exfoliants don’t sink to the bottom of the mold when we pour the soap, which is why we use a technique called “salt suspending” for some of our body exfoliants. Salt is heavier than soap, but when we mix it with a small amount of glycerin, it stays suspended in the bar, so every time you lather, you get a consistent amount of exfoliant on your skin. For face exfoliating soap, we don’t use salt because it’s too abrasive—we stick to the jojoba beads and oatmeal, which are finer and gentler.
I should also mention the ingredients that we intentionally leave out. A lot of cheap exfoliating soaps add fillers like talc, parabens, and sulfates, which don’t do anything for your skin except make the bar last longer or foam more. We don’t add parabens because they’re preservatives that some studies have linked to skin irritation, and we don’t use talc because it can clog pores and is not biodegradable. We also avoid adding artificial colors—many of our bars get their natural color from the exfoliants themselves: the walnut shell gives a light brown hue, the green tea we add gives a green tint, and the turmeric we use in some of our bars gives a warm yellow color. Green tea, by the way, is another ingredient we love—its antioxidants protect your skin from free radical damage, so it’s not just a colorant, it’s an extra skincare benefit. Turmeric is great for reducing redness and brightening skin, which is why we use it in our gentle face exfoliating soap.
Let me share a little story here—early in my soap-making career, I made the mistake of using too many walnut shells in a body soap. I was testing a new batch, and I thought more exfoliant meant better exfoliation. The first time I used it, I felt like I was scrubbing my skin raw, and a customer sent an email saying it had irritated her back so bad she had to take a week off work. That taught me a valuable lesson: exfoliation is about balance, not intensity. Since then, we’ve done hundreds of skin patch tests with our bars, working with dermatologists to make sure they’re safe for all skin types, including sensitive and acne-prone skin. We even have a bar specifically for people with eczema, which uses colloidal oatmeal and shea butter as the main exfoliants, because eczema-prone skin is so delicate that even mild abrasives can cause a flare-up.
Another thing that sets our exfoliating soap apart is the glycerin content. Glycerin is a natural byproduct of saponification, and it’s a humectant, which means it draws moisture to your skin. A lot of commercial soap makers remove glycerin from their base because it’s a valuable ingredient, and they sell it to other companies for use in lotions and creams. That’s why a lot of cheap soaps leave your skin feeling dry—they have very little glycerin left. At our company, we keep all the glycerin in the soap, which is why our exfoliating bars don’t leave your skin tight. The glycerin works with the exfoliants to keep your skin hydrated while you slough off dead cells, so you get the best of both worlds: smooth, soft skin without the dryness.
Now, let’s talk about what to look for if you’re buying an exfoliating soap as a supplier (since a lot of our customers are other small businesses looking to add our products to their shelves, and they ask me this all the time). First, check the ingredients list. If it has sodium lauryl sulfate at the top, that’s a red flag. The first ingredients should be oils (coconut, olive, shea) and the exfoliants, not harsh chemicals. Second, make sure the exfoliants are natural—if it says “polyethylene beads” or “plastic microbeads,” skip it. Third, look for chemical exfoliants that are natural, like lactic acid from milk or salicylic acid from willow bark, not synthetic chemicals. And fourth, check if the soap has glycerin—if it doesn’t mention it, it’s probably been removed.
I should also address a common misconception: some people think exfoliating soap is bad for daily use, but that’s only if it’s made with harsh ingredients. Our exfoliating bars are designed for daily use, and our dermatologist tests confirm that they’re safe to use every day on both the face and body—though we recommend the face bar for your face, since it’s gentler. The key is that the exfoliants are properly milled and the base is mild, so you don’t damage your skin’s barrier.
Let me wrap this up by saying that when I formulate a soap, every ingredient has a purpose. I don’t add anything just to make it look pretty or foam more. That’s why our customers keep coming back—they can feel the difference.
