Lip balm, being made of waxes and oils and butters, is very sensitive to temperature. You should try to keep your lip balm in a cool place whenever possible.
Never leave your lip balm in your car or in direct sunlight! It will melt, even the Summer Formula.
If you must keep your lip balm in a warm/hot location, keep it upright to prevent it from pooling against the side of the tube and/or leaking if it should soften or melt.
Some of the ingredients in lip balm do not respond well to repeated heating and cooling cycles. This may cause your lip balm to develop a "grainy" texture. While this is normal behavior for the ingredients, it is not desireable, so it is best to keep your lip balm at as consistent a temperature as possible.
Do not keep your lip balm in your pants pocket as it may heat up enough to soften and could leak or pool/deform.
Oh no! My lip balm melted! What can I do?
Here is how you can salvage your lip balm after a melting incident:
- First, if your lip balm is still very soft, place it upright in the refrigerator or freezer for a few minutes to solidify it enough to continue with these steps.
- Make sure the screw is all the way at the bottom position (the bottom part you turn to push the lip balm up) so that no lip balm extends above the rim of the tube.
- Leaving the cap off, place the lip balm upright on a microwave-safe plate.
- Microwave on high for 15-30 seconds—keep an eye on it the whole time—until it has liquified. Do not overheat your lip balm as the tube may deform.
- Carefully remove the lip balm and plate from the microwave and transfer to the freezer or refrigerator and leave it there for 5-10 minutes until it has totally solidified.
- Once it has solidified, you can replace the cap and your lip balm should be good as new!
