Disagreement between my mother and I- teens, your opinions please?

I have a problem known as excoriated acne. It means that I pick at my acne, without really thinking about it at all, much like you might bite your nails (which I also do). I have pretty good complexion, with a few zits here and there, but the problem is that when I get one, I pick at it, making that one worse and spreading the bacteria around to result in more acne.

My mother has approached me several times, and even gotten my father to mention it to me once, about seeing a doctor concerning this. She says it will leave scars. My response is that I don't care about a few scars (I honestly don't) I have fair skin so scars don't show up much anyways, plus I can always cover them up with makeup if I really wanted to.

Honestly, my acne is not all that bad. If it doesn't bother me, should it even be a problem? Its not like I have low self esteem; on the contrary, I am very confident and happy with myself. I care more about being a better person than my acne.
