Actinic Keratosis
"Dear the a: I have widespread actinic keratosis on my forearms. I was prescribed Efudex. I have thin, fair skin and some freckling. The damage seems to have occurred from a childhood playing outdoors, before sunscreen became so important. The Efudex, astonishingly, did nothing. So very disappointing. The dermatologist was equally surprised, and prescribed another round. Still nothing. And no one can give me an answer.  I am now considering a chemical peel or whatever the next step might be. So very tired of hiding my arms. Good luck to you. If anyone can give you an answer, please, please post it here."
