Place shea butter, cocoa butter, avocado oil and beeswax in the glass measuring cup.
Melt in the microwave for about 2-3 minutes. Please watch carefully as microwaves vary widely. You want the oils melted but not dangerously hot!
Add flavor oil to the mixture with your dropper and stir until combined.
Slowly pour the mixture into the lip balm tubes. Stop pouring when it reaches the top of the tube.
Let lip balms cool til just turning opaque. The butter/oil mixture will begin to shrink just a bit.
Now, using your dropper, top off the tubes with a bit more mixture, just to create a dome on the top. Do this slowly so it doesn't overflow and run down the sides of the tube. If it does overflow or make a mess, don't worry. Just let everything cool completely. Then you can just wipe or scrape off the excess. Trying to fix a drip while the mixture is still liquid will lead to a HUGE mess because the tube will likely fall over and... yep, lip balm everywhere!
Let lip balms cool completely, then pop on the caps. Cut out the LIP BALM LABELS and apply. Yay! You did it. Enjoy!
