This is my "emergency" lip balm because it has no SPF, but after getting sick of the SPF 50 aftertaste from my Paula's choice, I made the switch until I can find a suitable alternative. I'm in Southern California, and my car is usually in the garage; however, when I've taken the car out in 100+ degree heat, the balm really doesn't melt - and I bought it over a year ago, so if it was going to turn into goop it would have done so already.If you're sensitive to scents, you might like this product. I am, and I love it! This is almost exactly like Dr. Bronner's lip balm but doesn't melt if you look at it funny. It's not hard like Chapstick or other cheap balms where your lips have to warm it up before you can apply it. Even in cool weather, it glides on smoothly.I keep mine in the lower glove compartment away from direct heat - just in case. Every other lip balm I've put in the same location melted, but this one did not.
