I had really bad acne throughout my younger childhood, until finally I got put on a tropical acne gel, started taking birth control, and when I used fake-tanning it makes my skin look a lot better!

Problem is, I still have scars all over my face, especially on the right side.
What is the best way to clear this up? I'm sick of putting tons of concealer and foundation [oil-free of course] to cover them up!

Any relatively cheap ways? I've heard something about lasers ?
