How To Make Bath Fizz at Home

For those who love bath balms and bath fizz as much as we do, we decided to share how we make our own fizzies at home.

Did you know that bath fizz is relatively a new invention? It was invented in 1989 by Lush co-founder Mo Constantine who came up with the concept of bath bombs when trying to figure out how Alka Seltzer bubbles up when dropped into water. Thanks to her invention, we all get to spice up our bathroom experience with decorative bath fizz filled with ingredients that have great benefits to our skin and body.

Because bath fizz usually contain plant oil and other essential oils, you get to really enjoy the benefits of those ingredients when you take a bath filled with your favorite fizz. These ingredients are typically naturally derived so it can be considered as a better way to indulge your skin than some lotions out there filled with many ingredients that you’ve never heard of.

While our skin generally prevents many substances from being absorbed, some nutrients including CBD can penetrate through the glands and hair follicles and be absorbed into our body. When you soak yourself in a warm bath, the heat from the water causes vasodilation, which increases blood circulation, promoting further absorption of CBD and relieving sore muscles. Another key ingredient in bath fizz is the Epsom salt, which is rich in magnesium and sulfate. These ingredients combined are believed to provide detoxification benefits, relieve tension in your muscles and help exfoliate dead skin cells.

Don’t forget the aromatherapy benefit when soaking yourself in warm water filled with bath fizz. Benefits range from promoting relaxation to boosting immunity, which is definitely something we all won’t mind having a little more of.

For those who love bath balms and bath fizz as much as we do, we decided to share how we make our own fizzies at home. Check out our favorite recipe below:

What You Need To Prepare:

Dry Ingredients:

  • Baking soda (1 cup)

  • Citric acid (¾ cup)

  • Cornstarch (½ cup)

  • Epsom salts (½ cup)

Wet ingredients:

  • Sweet almond oil (3 tbsp) or * full-spectrum CBD Infused-oil (3 tbsp)*

  • Coconut oil (1 tbsp)

  • Various essential oils such as lavender (1 tsp)

  • Food coloret (1tsp)

Additional equipments to prepare:

  • Sieve

  • Whisk

  • Large bowl (for dry ingredients)

  • Small bowl (for wet ingredients)

  • Tablespoon

  • Teaspoon


  1. Pour 1 cup of Baking Soda into a large bowl. When pouring the Baking Soda, put the powder through a sieve to avoid large clumps getting into the bowl.

  2. Pour ¾ cup of Citric Acid through the sieve into the bowl the same way you did with Baking Soda.

    1. Baking Soda and Citric Acid is what creates the fizz.

  3. Next, add ½ cup of Cornstarch through the sieve the same way. Then mix all the ingredients together. You can use your hands if it's easier to mix.

    1. Fun fact, Cornstarch is actually what helps to slow down the reaction of Baking Soda and Citric Acid.

  4. Lastly, add ½ cup of Epsom Salt into the bowl and mix well.

Just like baking, it is important to make sure you mix the dry ingredients first before adding in wet ingredients into the mix.


  1. Pour 3 tbsp of Sweet Almond Oil in a separate bowl.

  2. Add 1 tbsp of Coconut Oil into the same bowl.

  3. You can also add your favorite essential oils (no more than 1 tsp) and 1 tsp of food coloret if you want to add some color to your bath fizz.

  4. Stir everything together until fully mixed.

Once nicely blended, add the wet ingredients into the dry ingredients. Mix the ingredients all together until it's fully saturated. Make sure all the clumps are removed and the texture is consistent across the board. Then put the mixture in the refrigerator so it settles a little more.

Once the bowl is cool to the touch, take it out from the fridge and pour the mixture into a jar to store. Leave the lid open for 10 minutes before closing, to let the moisture dry out so the fizz doesn’t get hardened when left stored.

Bath fizz and bath bombs usually have an average shelf life of around six months. Make sure to store them in a cool and dry place and avoid leaving the bath fizz in an area you feel can easily attract moisture. The more moisture it absorbs while stored, the less likely the bath fizz will fizzie up when it's actually time for use.
