Ive got a pimple problem.I've been using oxy for about a month and it doesnt seem to work. Wat do I do?

Ive used proactiv (till the cleanser ran out), clearisil, clean & clear, and oxy... Ive barely seen a difference... It clears up sorta, but only when I use it and then when i come back from school they're back. I use the daily wash, cleansing pads, & sometimes the 24 hour thing in the morning, when i come back from school, and b4 i go to sleep. Please help.
