Could a Dermatologist fix my skin?

I%26#039;m 20 and past the whole puberty thing but I still have really oily skin. I used to have moderate acne and since it went a way (I still get a few pimples every now and then), I have a bit of redness left from the acne. I also have a bit of redness running from under my nose to down around my mouth. It didn%26#039;t used to bother me. Now it kinda does. Could a dermatologist make it go away or at least make it almost go away? I just want healthy skin like everyone else in my family. Could they do anything about my oily skin? Thanks.|||Use NEOSPORIN on your face every night before bed. That should heal up most of your problems.
