I have a giant pustule that has reappeared four times in exactly the same spot over the past two months. It becomes a giant red whitehead that leaves red hyper pigmentation after it leaves. However, it never REALLY leaves. After it bursts (I don't pick it), I can still feel a tiny little speck, which lets me know that it's going to rear its ugly head in another week or two. How do I get rid of this sucker once and for all? I'm also on Accutane, so I have to be cautious about that as well. I just began my third month.
