Melt the shea and kokum butter together in a double boiler.
When melted, add the essential oil and mix well.
Pour into the lip balm tubes. This will make 1-2 tubes. Store in a cool place.
The kokum butter is very hard and will help to keep your blemish stick from melting. If you can't get a hold of kokum butter, you can add a very small amount of beeswax. Too much beeswax can clog your pores, making pimples worse.
