I have so many SKIN problems it's horriable?

First off it's my acne(no surprise) I sometimes have whiteheads alot but they are easy to get rid of.Now the problem is that I have some bumps on my nose were extremly large zits once grew they were poped.Now i don't know if they are acne scars or what cause they aren't red they are just like bumps(not even to big but noticable if you come in a good distance to me).Is there anyway to remove them?Now it gets gross.When I finish bathing and I get out the show and I dry off now when I rub kind of hard it's like the DIRT in my skin rubs of and the spot becomes clear is there anyway to get rid of OVERALL bodily dirt without having to rub myself when damp?
