One day, I realized that commercial lip balm was made of nasty petrochemicals and started looking for alternatives. There were a lot of pricey boutique brands and I tried a few, and then I found a product made by Chapstick, which was made with several exotic butters, like shea and aloe. These moisturized my lips while protecting them from the drying effects of wind and sun.
But, alas, all good things come to an end, and Chapstick stopped making them. The last ones are now available, but very pricey, up to $10 a tube.
So I decided I'd try to make my own.
