Place the lip balm tubes in the filling tray, and gently pour the mixture into them. Then scrape away the excess using the spatula.
Using the low heat setting on your heat gun, smooth out the tops and release any air bubbles that have become trapped in the lip balm.
Let the lip balm set for at least half an hour before removing the tubes from the tray and putting on the lids.
Notes
Homemade lip balm is shelf-stable and can be stored in a cool, dark location for up to a year.
Tips
Use a double boiler – If you melt the ingredients too quickly, you can burn them which may lead to a darker color and bad smell. Melting the ingredients in a bowl over a pot of boiling water also works if you don’t have a double boiler.Avoid contamination with water – Water in lip balm can cause mold to grow, so make sure to avoid getting any water in it during the melting process.Swap other essential oils – I used rose essential oil for this lip balm, however, you can use any type of skin-safe essential oil or essential oil blend. You can even leave out the essential oil if you prefer unscented lip balm.Cool at room temperature – Once the lip balm has been poured into the tubes, let it set at room temperature for a smoother finish.
