Fuck all that noise. I will tell you the most effective acne cure that I've ever found. It's extremely cheap, easy to obtain, and the process itself is WAY easier then Proactiv and all that other bullshit. It's very simple. Apple Cider Vinegar.
Yes, I'm serious.
Take a cotton ball, or a wad of toilet paper or whatever, soak it in apple cider vinegar, and rub on acne areas before bed. Go to sleep with it on. At first it may sting just a teensy tiny little bit for a few seconds, but unless youz a bitch, it shouldn't bother you. That's it. Just rub apple cider vinegar on your face. It works better then any top-of-the-line acne cures and meds out there. Why?
Simple. Apple cider vinegar has the same PH level as your skin, and hair. On top of that, it kills bacteria that causes acne. So it will not only kill acne, but it's completely healthy and will make your skin feel nice!
No, I'm not trolling. Seriously, try it. If I ever do get acne I just rub some apple cider vinegar on my forehead(or wherever) before bed and wash my face with just water when I wake up. You'll notice a difference very quickly. Within a day or two.
