If you’re looking for a gentle yet powerful soap to help detox your skin, look no further than this Homemade Charcoal Soap. Made with just four ingredients, this easy melt-and-pour soap recipe is perfect for beginners and a great way to incorporate activated charcoal into your skincare routine. Tea tree oil adds a fresh, clean scent and provides natural antibacterial properties, making this soap ideal for oily or acne-prone skin.
Charcoal soap is popular for its ability to draw out dirt, oil, and impurities from the skin. But store-bought versions often contain extra fillers or harsh ingredients. By making it at home, you control every ingredient that goes into your soup—and it’s surprisingly easy!
This recipe utilizes a melt-and-pour soap base, eliminating the need to handle lye and avoiding the complexities of curing times. It’s an excellent project for beginners and seasoned crafters alike.
How to Make Charcoal Soap
For this DIY, you will need a melt and pour base, activated charcoal, isopropyl alcohol, and tea tree oil.
Chop the melt-and-pour soap base into 1-inch cubes and place them in a microwave-safe bowl.
Microwave in 30-second intervals, stirring in between, until fully melted. Be careful not to overheat the soap.
In a small bowl, mix the activated charcoal with one teaspoon of isopropyl alcohol. Stir well until smooth with no lumps.
Pour the charcoal mixture into the melted soap base. Add the tea tree essential oil. Stir until thoroughly combined.
Lightly spray your silicone mold with isopropyl alcohol to reduce bubbles and ensure a smooth finish. Pour the soap mixture into the mold.
Spray the surface of the soap with more isopropyl alcohol to eliminate bubbles. Let the soap harden at room temperature for 30–45 minutes.
Once the soap is firm, gently remove it from the mold. It’s ready to use immediately!

Substitutions & Tips
One of the best aspects of making your own soap is that you can tailor it to your specific needs. Here are some simple substitutions and tips:
- Soap Base: Use a glycerin base for a translucent bar, or try a shea butter or goat milk base for added moisture. All work well with activated charcoal.
- Essential Oil: Tea tree is excellent for acne-prone skin, but you can swap it for lavender (soothing), peppermint (invigorating), or eucalyptus (clarifying).
- Add-ins: Try adding dried herbs like lavender buds or ground oatmeal for texture. Just be sure not to overload the mixture.
- Color: Want a swirl effect? Only mix part of the charcoal mixture into the base for a marbled look.
How to Use Charcoal Soap
Use this soap on your face or body once a day as part of your regular skincare routine. It’s particularly beneficial after workouts or on hot, humid days when skin can feel extra grimy.
Avoid using it more than once a day if you have dry or sensitive skin—activated charcoal can be drying when overused.

FAQ
Can I use this on my face?
Yes! This recipe is gentle enough for facial use, especially when paired with a moisturizing soap base, such as goat milk or shea butter.
Will charcoal stain my skin or sink?
No. When properly mixed, activated charcoal won’t stain skin or leave residue. It’s also suspended evenly in the soap thanks to the isopropyl alcohol.
Can I use more essential oil?
You can add up to 40 drops for a more pungent scent, but be cautious—too much essential oil can irritate skin. Always use skin-safe oils.
How long does homemade soap last?
When stored in a cool, dry place, these bars will last 6–12 months. Store them in an airtight container or wrap them individually for best results.
