Homemade Lavender & Tea Tree Soap Recipe with Activated Charcoal

I may receive compensation from links on this site. See my disclosure policy.

Activated charcoal soaps are super popular for helping to fight acne. And for good reason! They really work on acne prone skin. So I decided to take the classic lavender and tea tree soap combo that’s been used traditionally to help fight acne and combine it with activated charcoal.

DIY Handmade Lavender and Tea Tree Soap Recipe with Activated Charcoal for Acne Prone Skin

This well balanced combination of soapmaking oils, activated charcoal and essential oils make my homemade lavender and tea tree soap recipe with activated charcoal great for anyone prone to acne regardless of skin type.

Activated Charcoal Lavender & Tea Tree Soap Recipe

© Rebecca’s Soap Delicatessen


10.8 oz. hemp seed oil
7.2 oz. palm kernel flakes
9 oz. 76°F melt point coconut oil
7.2 oz. macadamia nut oil
1.8 oz. shea butter

5.2 oz. lye/sodium hydroxide
11.5 oz. distilled water

.72 oz. lavender essential oil
.36 oz. tea tree oil
2 Tablespoons activated charcoal


This is a cold process soap recipe therefore to create this homemade soap recipe you’ll need to follow your basic cold process soapmaking instructions and remember to take all safety precautions.

Using a digital scale begin by weighing out the water and lye separately, then pour the lye slowly into the distilled water and mix until all of the lye has dissolved. Set aside to cool.

Now prepare your soapmaking oils by weighing them out and combining in a large stainless steel pot. Heat on the stove over medium heat until all oils have melted then remove from heat and allow to cool.

Once the lye-water and oils have cool to about 100°F mix the lye-water and oils together using a stick blender. At light trace add the essential oils and activated charcoal and mix completely, then prepare into your prepared soap mold. (This soap recipe will fit in one of my DIY wooden loaf soap molds and yields 10-12 bars.) Cover and insulate for 24 hours.

After the insulation period, unmold the soap loaf and cut into bars. Allow to cure 3-6 weeks before use, then wrap and label as desired.

  3. Chad Kendall says

    I am new to soap making and was wondering what type of mold do you use to get your soap so perfectly shaped on all four sides?

  4. lynne simms says

    I made the tea tree and lavender soap with the activated charcoal recipe as posted here. It came out wonderful and the smell is awesome!!
    Thank you Rebecca

  5. hello,
    im wondering if i were to make this in liquid form but with a few added oils how much lye would i use?? also is there a different coconut oil to use for liquid soap??

    • Liquid soapmaking is a different process than regular cold process soap and you would use potassium hydroxide instead of sodium hydroxide. You’d need to research how to make liquid soap and run your recipe through a lye calc using potassium hydroxide for the correct amounts of potassium hydroxide and water needed. Different oils also have different SAP values and would require running this back through a lye calc for regular CP soap as well.

  6. I was wondering what the difference between palm kernel flakes and palm oil are, and if the can be substituted for each other.

  7. Tricia Romanishen says

    I was wondering if anything can be substituted for the macadamia nut oil?

  8. I made this soap for my 13 year old daughter with acne prone skin. I absolutely love it!!!! Thank you so much for sharing your recipes!! I’m new to soap making and love your website!! Here’s a link to the soap I made following your recipe to a “T”

  9. Just curious if you know why distilled water is used? What might the difference be if using tap or previously boiled water. Thank you your soap looks gorgeous!

    • Tap water has chemicals and metals in it that can negatively react with the lye. Boiling water won’t remove the chemicals and such like flouride, etc., thus the distilled water.
