They are starting to struggle with acne and oily skin. I live with skin that is very much at the other end of the spectrum, my skin is very dry, so I don’t recommend this bath bomb for those with dry skin.
It is meant to help calm inflamed, oily, acne prone skin. My kids just care that it looks super cool since it’s black. And apparently, just like when I was a teenager, black is the cool colour. An unexpected surprise with these bath bombs was when my kids used them and said the swirling black water was like Dementors! So yes, this could be a Harry Potter bath bomb recipe too! The benefits for my teens skin with these bath bombs are quite extensive. No teen loves acne, especially when they are getting breakouts on their backs and shoulders.
A soak with these bath bombs will help calm those break outs! Activated charcoal is great at helping wash oils from the skin (I use it in my blacksmith soap we use to clean our hands after working in the forge). We also use coconut oil which will not clog pores and has wonderful anti-bacterial properties to help with those little infections. If you want to up the skin care punch of these bath bombs you can add in other ingredients like: Evening Primrose Oil which helps with skin inflammation and eczema or Grapeseed Oil which has some astringent properties which help with acne prone and oily skin. I keep both of these ingredients on hand and included them as needed when the kids need a little extra skin care. You will need to adjust your recipe accordingly if you add these oils to ensure your ratio of oils to dry ingredients still works. For now though I will share our basic black bath bomb recipe. Make sure you also check out our Galaxy Bath Bomb Recipe that also uses activated charcoal. 2 cups baking soda 3/4 cup citric acid 1/4 cup SLSA 1/4 cup cream of tartar 1 cup cornstarch 1/3 cup coconut oil 2 tablespoons polysorbate 80 10-20 drops each of cardamom and rosemary essential oil Activated charcoal powder Black biodegradable cosmetic glitter (optional) Black decorative sugar Spray bottle of rubbing alcohol 1 large mixing bowl 1 small microwave save measuring cup or bowl Measuring cups and spoons Bath Bomb Molds Disposable gloves Parchment paper. First, whenever I have kids helping me with any project I like to protect my table. I like to grab parchment paper and just lay it over my table before setting out supplies for bath bomb making. This step is especially important when working with activated charcoal which really likes to get into everything. Trust me, taking a moment to prepare your space will save you a lot of headaches with clean up. Start out by adding the baking soda, citric acid, SLSA and cream of tartar to a large bowl. Citric acid can be very irritating if you inhale it. If it bothers you make sure you work in a well ventilated space and consider using a face mask. My youngest skips helping with this step because he really can’t stand citric acid in the air (and his enthusiastic mixing really likes to launch it into the air!). Once it is mixed with our oils he helps with all the other steps. Add your coconut oil to your microwave safe bowl and melt in the microwave for a few seconds until it is liquid. If you decide to add in Grapeseed Oil or Evening Primrose Oil, add it in during this step as well. Add the oil mix to the dry mix and blend everything together. Start by adding one tablespoon of activated charcoal to your mix.
Once it is blended, if you want it darker, add a bit more. Now you can add in your glitter if you wish to use it and mix everything together. Use your hands to really mix it in well and make sure there are not clumps or lumps. You will know when the mixture is perfect when it feels like wet sand and you can press the mixture together in your hands and it stays together. If you find the mix is not getting to the wet sand stage despite extensive mixing, it may be that you need a bit more moisture in your mix.
I find in our Canadian winters I need to use a bit more oil in my mixes because our air is so dry. So if it is dry, just add a little drizzle of coconut oil and mix well until you get the right consistency. Sprinkle a bit of black edible sugar into one of your molds.
