I am 18 years old and I still have acne. I have tried everything, including proactive, and nothing works. Can you help me?

I’m 18 years old and have quite a few acne scars on my face, are there any natural remedies or procedures for scar removal? Even if it takes some time but is effective is fine by me.
Answers with experience and knowledge most appreciated!!! =)
