I actually had a bad reaction to Aquaphor last fall after using it as a lip moisturizer -- it chapped the hell out of my lips to the point where they were swollen and shedding. That healed but provided an opportunity for a yeast infection to develop, which resulting in constant cracking in the corners of my mouth (angular cheilitis) and strange white bumps on my lips. During that whole mess I switched from Chapstick to the beeswax/olive oil lip balm that they sell at the LL Bean store near me. I also tried Neutrogena lip balm, and that seemed okay. Once I was able to figure out that I was dealing with a yeast infection (several doctors were unable to diagnose it correctly) and I got it under control, things were good except for the line of dry chapped skin along the top margin. Now I go back and forth between regular Chapstick and the beeswax/olive oil and things seem okay. However neither lasts long enough or has high enough SPF for long summer bike rides.
