I am wondering if your take ibuprofen. I had horrid, deep, painful Acne on my face that was unyeilding after multiple attempts to treat. I have discovered by chance that it was ibuprofen that was causing the breakouts.
Still get a few small pimples, but they are managable. They don't hurt and clear up quickly on their own.
It could be effecting your GI track as well.
best wishes
