Hey girlie,
Proactive is good stuff. One of the best things I've tried so far. It's definitely worth trying, even if you don't stay with it.
Glycolic acid is key; salacylic acid is Ok but it doesn't exfoliate your skin like the glycolic acid does.
The proactive kit usually comes with a complimentary face mask too. It's a sulphur mask and it was great stuff. The only part about it that stunk was, well, it stunk. For a couple of days after you use it, when you get your face wet, you can smell sulphur. My mom and I used to joke about it and call each other fart face [laugh]. Worked like nobody's business for me though.
