being aware is the only solution....I used to pick my face...scratch off a little bump until it bleed then picked the scabs until I had at least three dozen all over my face. First I became aware I was doing it and then how I felt when I was doing it then decided every time my hands went up to my face --I would sit on them--literally until the desire went away. Don't pick, no scars, don't even touch my face at all
