The guy at acne.org knows his shit. If you know anyone who has a problem like that, I would recommend looking at his site. I had serious problem skin my entire adult life until I saw his site (like, constantly at least one or two huge zits at any given time), and now I haven’t had a single problem in half a year. Who knows what the repercussions will be when I’m old 
but for this decade, he’s really hit on something.
I know I sound like a commercial for him, but you can buy everything OTC from multiple brands. If you have problem skin, this is totally the solution. It’s like magic.
