Melt the beeswax. You can do this in the microwave or create a double boiler by placing a heat-proof bowl over a small pot filled with a little bit of water.
Once the beeswax’s melted, add shea butter and oil and stir. The heat of the wax should melt the shea butter too. If not, put the bowl back into the microwave for a few seconds or back over the (probably) still steaming pot and wait a few moments.
If you like to add essential oils, wait until the mixture’s cooled down a bit further. If you don’t use them, simply pour the oil/wax mixture into 6 small containers or tubes (whichever you like). Put your tubes/containers into the fridge to solidify the lip balm. This can take up to 2 hours plus.
