I used the scientific method, and now I look like the Joker. (Why so serious?) The whole sob story can be found below.
 

Last winter/spring, I was getting very chapped lips, so I, naturally, put lip balm on 'em. I had happened to buy some SPF 30 lip balm for entertainment value--that's a really high SPF for lip balm, which amused me, plus it was on sale (always a plus). Despite the quantity in which I used this, it didn't help alleviate the ickyness. After a time, I came to hypothesize, based on this data, that perhaps the lip balm was exacerbating the problem, or that I was perhaps allergic to some ingredient in it. In the interests of science, I wanted to test this to make sure.
 
Ah, the scientific mindset. Youch, that itches like blazes! I wonder if that discomfort is a reproducible result.
 
I applied a healthy dose of said lip balm this week, which resulted in unhealthy results. I did have a reaction to it, and how! It's kind of like the famous poem someone told me in high school:
Little Johnny had a drink
But he shall drink no more
For what he thought was H₂O
Was H₂SO₄.
 
This is an excellent way to begin the first week of classes, itchy and red about the mouth (on Sunday, I could only open my mouth with approximately enough clearance for small pretzels). I am, however, vindicated in my hypothesis! Consequently, I hereby give permission (as my celebratory largesse) to all who see me in allergy mode to bombard me with Batman quotes.
