That stuff is sooooo bad for you but it must suck having severe acne I grew up with just moderate acne and I hated it.
My acne went away once I stopped using acne medicine rub stuff and switched to good face and pore cleansing products that were mild and had no acid stuff in them. I realized soap just made acne horrible and using acne medication without properly washing my face had no progress. A lot of people try to fight the acne instead of fighting what causes the acne, but considering you're using some hardcore stuff to treat yours I am guessing simple remedies won't do you any good.
