Allergic to my own sweat?

This is so weird... I have slowly discovered I am allergic to my own sweat!
...Luckily not all the skin on my body is, just certain areas; like most recently, the skin from the corner of my lip (including my lips) to my chin, has broken out in a rash. This only happens when I do activities outside, that make me exert enough energy to start sweating from my face (lips). I am not sure if it's because I wipe the sweat off with my gloves (which I wash after every ride, perhaps allergic to the detergent) or if there's hormones that come out in my sweat that the delicate skin on my lips can't handle!
Whatever it is, I feel like Ronald McDonald... with my big, red, glowing lips! (That's HOT! lol)
