I used to skin pick only at my acne. My whole face was scars and red spots from me picking at scabs a new pimples. The only thing that got me to stop was getting acne treatment which took a really long time for me to even fine one that worked. Once my acne cleared up I found that after a while, with nothing to pick at it was easy to stop even when pimpled did appear back once in a while. Here is the URL to the place I got treatments at if anyone is interested.
What else worked for other people? or have you had a similar experience?
