Hello, I was hoping someone might be able to help me determine if this is some sort of rash, acne or folliculitis. I've been trying to treat is with a SA face wash and 2.5% bp but so far no change and sometimes (like now) it seems to get more aggravated. I do have adult cystic acne but most of it is currently gone. I was using proactiv but one day it stopped working completely and after trying several new products I've developed this reaction. It gets worse when I sweat and itches, Benadryl has no affect on it, my hair seems to irritate it if I wear it down. It's not too terribly bad on my chest right now but it randomly flares up and then calms down after a few days. Help please!
