perioral dermatitis
"I've been using Protopic (0.1% ointment) for about six years to treat facial seborrheic dermatitis. On the plus side, Protopic ended five miserable years of itching, redness and burning that no cream seemed to help, and for that reason I am truly thankful. On the downside, it's very greasy (similar to Vaseline) which means it stays on the skin all day if applied in the morning. Drinking alcohol is a definite no-no too, as a tiny amount causes an awful reaction, making the skin immediately burn bright red.  Annoyingly, if I don't use Protopic for about two weeks, when I reapply it the skin burns and itches intensely for a few hours (REALLY uncomfortable). Using it more often, say twice a week, does however resolve this problem."
