how do you fight pimples/acne?

this question is by far unrelated to yaoi or whatsoever but i had to ask because i am a 20 years old girl who's face cant seem to be free of it. and it does lowered my self asteem. i have tried cetaphil, dalacin t, pills, meet with doctor and such it is quite helpfull but then it come back and now i'm trying the apple cider vinegar. hopefully it will be the resolution. so does any of you share similar stories as mine?
