A few weeks ago, I had some seriously cracked corners on my mouth, especially one side. After doing a little research, it appears I had something called angular cheilitis. In severe cases, the splits can be so deep, bleeding can occur. Luckily, I just had a minor affliction, brought on by some prescription acne medication that I had inadvertently gotten too close to my lips. But angular cheilitis can be caused by many factors: a deficiency of vitamin B12, iron, or zinc; a bacterial or fungal infection; or simply dry weather.

After purchasing some Blistex to relieve my symptoms, I noticed that I seemed to be applying the balm with greater and greater frequency. Is there some kind of phenomenon that makes applying lip treatments somewhat of an obsessive action? Perhaps it's the menthol (which turns out, is actually quite drying) or pepperminty addition that gives us a little rush, or maybe it's simply our subconscious way of keeping a wound in check. Find out some tips on preventing dry, chapped lips here, and then tell me: are you obsessive about your lip balm applications?
