I have had acne since I was about 13 years old. Over the last two years or so it has been at a managable level. Recently I noticed that I have these bumps all over my face (quite densely positioned, too), underneath my skin. You cannot notice it that much outside or from a medium distance but if you look closely you can see a lot of it.

I gave into the infomercials and tried my hand at Proactiv. It worked for a bit but I couldnt use it that often because it would make me break out even worse. I moderated my use with it and it made it better, but my skin seems to be too complicated for it.

I've recently been trying to use an at-home micro-dermabrasion kit and it seems to make my pores and problem areas look less visible, though I am not sure whether to continue with that or find something that would just get rid of my acne first, before trying to cure my pores/scarring.

My skin is really oily at times, but in other instances I find it to be really dry with dead skin cells on the surface.

I guess my questions are:

1) What could the semi-invisible bumps be underneath my skin?
2) What kind of treatment should I use for my skin?
3) Has anyone here been able to free themselves from acne scarring?
