What Is Charcoal Soap and Is It Worth Trying?

Charcoal soap has become one of the most popular products in the natural skin care world. But what does activated charcoal actually do in a soap, and does it live up to the hype? Here's an honest guide.

⚕️ Important Note

This article is for general information only. Charcoal soap is a cleanser, not a treatment for acne, oily skin, or any other skin condition. If you have specific skin concerns, consult your dermatologist. Individual results vary, and what works for one person may not work for another.

Quick Summary
  • Charcoal soap is a bar soap that contains activated charcoal, a fine black powder made from carbon-rich materials like coconut shells or bamboo
  • Activated charcoal is widely used in water filtration and medical settings for its ability to bind to certain substances
  • In soap, charcoal adds a deep cleansing element, many people find it effective at removing surface build-up and excess oil
  • It gives soap its distinctive black colour and a slightly different feel compared to regular bar soap
  • Scientific evidence for specific skin claims is limited, charcoal soap is best understood as a thorough cleanser, not a skin treatment

What Is Activated Charcoal?

Activated charcoal is not the same as the charcoal briquettes you'd use for a barbecue. It's a fine, black, odourless powder made by heating carbon-rich materials, typically coconut shells, bamboo, or hardwood, to very high temperatures. This process creates a highly porous structure with a massive surface area relative to its size.

This structure is what makes activated charcoal useful. The processing creates an enormous surface area relative to its size, which gives activated charcoal its ability to bind to (adsorb) certain substances. This property has made activated charcoal widely used in water filtration systems, emergency medicine (for certain types of poisoning), and air purification.

In the skin care world, activated charcoal has been incorporated into soaps, face masks, toothpaste, and cleansers based on the idea that the same binding properties that work in filtration might help draw out impurities from the skin during washing. The extent to which this actually happens during a short wash is debated, but the popularity of charcoal in skin care continues to grow.

What Does Charcoal Soap Actually Do?

Let's be honest about what charcoal soap does, and what it doesn't, based on what we actually know:

🧹

Thorough Cleansing

Charcoal soap provides a deep cleansing experience. The activated charcoal particles add a gentle texture to the soap and many people find that their skin feels particularly clean after use. Whether this is the charcoal specifically or the soap formulation overall is hard to separate, but the result is a noticeably thorough wash.

🫧

Oil Absorption

Activated charcoal is known for its ability to absorb oil. In soap form, this may help remove excess surface oil more effectively than a regular bar. Many people with oily or combination skin find charcoal soap leaves their skin feeling balanced, not stripped, but not oily either. Individual results vary.

🖤

Distinctive Appearance

There's no getting around it, charcoal soap is striking. The deep black colour comes from the activated charcoal itself and makes for an eye-catching bar. The colour rinses away cleanly and won't stain your skin, tub, or towels.

🌿

Natural Ingredient

Activated charcoal is derived from natural sources (typically coconut shell) and is chemical-free in itself. It adds function to the soap without adding synthetic compounds. In our charcoal soaps, it sits alongside the same natural goat milk soap base used across our entire range.

Charcoal soap is a thorough cleanser with a distinctive character. It's not magic, but for people who enjoy a deep-clean feel and appreciate the unique look and texture, it's a worthwhile addition to your routine.

What Charcoal Soap Doesn't Do

There are many claims made about charcoal soap online. It's important to separate what's plausible from what's exaggerated:

It Doesn't "Detoxify" Your Skin

The concept of "detoxifying" through soap is not supported by dermatological science. Your liver and kidneys handle detoxification, not your cleanser. Charcoal soap cleans your skin. It doesn't pull toxins from your body.

It Doesn't Treat Acne

While charcoal soap may help remove excess surface oil (which can contribute to breakouts), it is not a treatment for acne. Acne is a complex condition influenced by hormones, bacteria, genetics, and many other factors. If you have acne, a dermatologist can prescribe appropriate treatments. Charcoal soap can be part of a cleansing routine, but it shouldn't replace medical advice.

It Doesn't Work the Same for Everyone

Skin is complex and deeply individual. What makes one person's skin feel great may not work for another. Charcoal soap is generally well-tolerated, but some people with very dry skin may find it too drying. A patch test is always recommended when trying a new product, and consulting your dermatologist is the safest approach if you have specific skin concerns.

Who Might Enjoy Charcoal Soap?

People Who Prefer a Deep-Clean Feel

If you enjoy the sensation of your skin feeling particularly clean and fresh after washing, not just washed, but deeply cleansed, charcoal soap delivers that experience. The activated charcoal adds a dimension to the cleansing that regular soap doesn't.

People with Oily or Combination Skin

The oil-absorbing properties of activated charcoal may be particularly appreciated by people whose skin tends toward oily. Many people with oily or combination skin find that charcoal soap leaves their skin feeling more balanced than regular soap. If you have very dry skin, a gentler option like our regular goat milk soap may be more comfortable.

People Who Like Something Different

Let's be honest, part of the appeal of charcoal soap is that it's interesting. The black colour, the slight texture from the charcoal particles, the knowledge that you're washing with something unusual. For people who enjoy variety in their bathroom products, charcoal soap adds something different to the rotation.

People Looking for a Gift with Visual Impact

A black soap bar is visually striking. Charcoal soap makes a memorable gift, it stands out, looks interesting, and sparks conversation. Paired with other products from our range, it makes an eye-catching addition to a gift set.

How to Use Charcoal Soap

Use It Like Any Bar Soap

There's no special technique. Wet the bar, lather between your hands or on a washcloth, apply to wet skin, and rinse. The black lather is normal, it comes from the charcoal and rinses away completely. Your skin, towels, and bathtub will not be stained.

Start with 2-3 Times Per Week

Because charcoal soap is a more thorough cleanser, some people find daily use slightly drying, particularly if they have naturally dry skin. Starting with 2-3 times per week and alternating with a regular goat milk soap on other days is a good approach. If your skin responds well, you can increase frequency.

Moisturise Afterwards

As with any cleanser, applying moisturiser after washing helps lock in hydration. This is especially worth noting with charcoal soap, since the thorough cleansing may remove slightly more surface oil than a gentler soap.

Patch Test First

If you have sensitive or reactive skin, do a patch test on your inner wrist before using charcoal soap on your face or body. Wait 24 hours to check for any reaction. As with all products, individual responses vary.

What's in Our Charcoal Soap?

Our charcoal soaps use the same goat milk soap base as our entire range, goat milk, natural oils (olive, coconut), fragrance oil, and skin-safe colour, with the addition of activated charcoal. The result is a bar that cleans deeply while still benefiting from the gentle, moisturising properties of the goat milk soap base.

No SLS, no parabens, no synthetic dyes, no harsh detergents. The activated charcoal provides the dark colour naturally, no artificial colourants needed. Every bar is handmade in Melbourne in small batches.

Charcoal Soap vs Regular Soap , How They Compare

Cleansing Depth

Charcoal soap provides a more thorough cleanse than regular goat milk soap. Regular soap is gentle and moisturising, charcoal soap adds a deeper cleansing element on top of that foundation. Both clean effectively; charcoal soap just goes a bit further in removing surface build-up and excess oil.

Feel After Washing

Regular goat milk soap leaves skin feeling soft and comfortable. Charcoal soap leaves skin feeling clean and fresh, still comfortable (thanks to the goat milk base), but with a more "reset" feeling. Neither should leave skin feeling tight or stripped.

Best For

Regular goat milk soap is the gentle everyday option, suitable for all skin types, daily use, face and body. Charcoal soap is the deeper-clean option, particularly good for oily or combination skin, or for days when you want a more thorough wash. Many people keep both and alternate based on their needs.

Frequently Asked Questions

No. The black lather rinses away completely. Your skin, towels, and bathtub will not be stained by charcoal soap. The colour comes from the activated charcoal itself (a natural ingredient), not from a dye, it disperses in water and drains away cleanly. A quick rinse of the tub after use removes any trace.
Charcoal soap is a cleanser, not an acne treatment. It may help remove excess surface oil, which can contribute to a cleaner skin surface. But acne is a complex condition caused by multiple factors, hormones, bacteria, genetics, and more, that a cleanser alone cannot address. If you have acne, consult your dermatologist for appropriate treatment. Charcoal soap can be part of a cleansing routine, but it shouldn't be relied upon as a solution for acne.
Some people do use charcoal soap on their face, particularly those with oily or combination skin who enjoy the deep-clean feel. However, facial skin is thinner and more reactive than body skin. If you want to try it on your face, do a patch test on your jawline first and wait 24 hours. Use it no more than 2-3 times per week rather than daily, and always follow with moisturiser. If your skin feels tight, dry, or irritated, switch to a gentler option. Consult your dermatologist if you have specific facial skin concerns.
Charcoal soap is made with the same gentle goat milk base as our regular soaps, no SLS, no synthetic detergents, no parabens. However, the activated charcoal adds a deeper cleansing action that some people with very sensitive or dry skin may find slightly drying. If you have sensitive skin, start with 1-2 uses per week and see how your skin responds. Our regular goat milk soap is a gentler everyday alternative. If you have a diagnosed skin condition, consult your dermatologist before introducing charcoal soap. Read our full sensitive skin guide.
They share the same goat milk soap base, same natural oils, same goat milk, same gentle cleansing. The difference is the addition of activated charcoal, which provides a deeper cleansing action and gives the soap its distinctive black colour. Regular goat milk soap is the gentle everyday option. Charcoal soap is the deeper-clean option for days when you want a more thorough wash. Many people keep both and alternate depending on their needs.
Some people with oily skin use charcoal soap daily without issues. For most skin types, 2-3 times per week is a good starting point, alternating with regular goat milk soap on other days. This gives your skin the deeper cleanse without overdoing it. If your skin feels comfortable with daily use, you can increase frequency. If it feels tight or dry, reduce to 2-3 times per week. Everyone's skin is different, the right frequency depends on your skin type and personal preference.
