So I few weeks ago, I got this little patch of dry skin on my forehead. I put some lotion on it and the next day, there were little bumps there instead of the dry skin and the bumps became little blisters. Eventually the blisters pop and they wont stop pussing. I keep putting cortezone 10 on it thinking it's excema but it keeps coming back (like every week). Has anyone had a problem like this? HELP!

PS - I'm 20 years old and I have never had severe acne problems.
