You don't need to be scared about going to the mental health professionals about it. I went to see a doctor last week about my skin picking for the first time, and was utterly terrified. He didn't laugh or anything, but was gentle and referred me for cognitive behaviour therapy (CBT). Since, I've spoken to a couple of psychologists about it, naming it dermatillomania. They hadn't heard of it before, so it helped to compare it to trichotillomania, and they were very understanding. I'm still on the waiting list for therapy, so I can't tell you if it's helped yet, but I'd recommend going to the doctors about it. Dermatillomania is on the OCD spectrum, so maybe you'll get some meds, but CBT is meant to help cure both anyway.
