I should have specified that I am a 27 year old male, my diet is absolutely terrible and I don't get a lot of exercise working in IT so that may be a factor. Also my lips don't really crust up like other cases I have seen. I'm not sure if that is because I keep my lips constantly moist with lip balms or I actually might have actinic cheilitis instead of exfoliative cheilitis again not exactly sure.
