proactiv is nothing groundbreaking.
it's the system that works for people
1.) salycid acid face wash
2.) some type of toner/exfoliate
3.) some type of moisturizer to replenish after exfoliating
4.) (optional) some type of benzyl peroxide for existing blemishes
all the "acne systems" follow this formula because that's what you're SUPPOSED to do to your skin.
pretty good for the face, but hard to start doing that on your back or shoulders. you'll run through that shit in a week
