lip issues

my lips have been really dry and itchy for the past few weeks. i thought i was allergic to something i've been using...but i haven't really used any new products lately. it's so annoying because i have to keep lipbalm with me at all times. otherwise my lips just get all itchy and dry. blah...i'm having one of those days. you would think i'd be in a better mood considering i get to work from home today. my boss is kool like that.
