Start by measuring out all your ingredients. If you're using a lip balm tray kit, place the tubes into the tray now.
Fill the cooking pot halfway with water and place it over medium-low heat. Put the glass bowl on top of the pot to create a double boiler.
Add the coconut oil, shea butter, beeswax, almond oil, and vitamin E oil into the bowl, stirring occasionally until everything has fully melted (about 10 minutes).
Once everything has melted into a smooth liquid, remove the bowl from the heat.
Optional: Add your chosen essential oils to the mixture and stir well.
Carefully pour the melted mixture into a mason jar to cool for a couple of minutes. Then, pour the liquid into your lip balm tubes or containers. If you're using a tray kit, you can simply pour it into each tube.
Allow the lip balm to cool and harden for about an hour. Once set, cap the tubes and store them in a cool, dry place.
