How to remove acne scars?

When pimples or boils appear, I have a tendency to can't help but want to remove them.

I just can't help but get involved.ㅜ

As a result, it has become a scar and looks like freckles.

And there are about two areas that are sunken in.

What kind of treatment would be needed for this kind of skin, and how much would it cost? Is it probably expensive?

How much is the average?
