Best advise i can give is see a dermitoligist, its so easy, call around for a cheap one and one you can get in fast.
I got in the very next day, it was easy as shit.
I sat down, he said, "what ya seeing me for".
I simply told him to prevent break outs, he asked if I'veb ever been treated for it before, i say no.
He writes out a perscription for a antibiotic "TETRACYCLINE 500MG"
Costed $7 for the perscription, works great.
