This will only work if you pick in the mirror. Get rid of your mirrors and cover the ones you can't get rid of with decorative window film. I have one mirror in a poorly lit area for putting on makeup. It is screwed to the wall, so i can't move it to somewhere better lit. I also covered the mirror on the back of my car visor with duck tape. I picked for 30 years. I could spend hours in the mirror. I used needles. There was never even one day that went by without picking. I was not a mild case. I'd tried covering my mirrors before with curtains but they were too easy to move. Then I did this and, voila!, no more picking. I am still not picking 3 years later. I am still incredulous that this worked. I know it sounds you good to be true. But, after years of trying to stop, I just stopped and it was easy.
Unfortunately, I'm here now because my son has begun picking. He doesn't user a mirror so my miracle cure won't help him. But, i figured maybe it will help someone. You can get the film at Lowes or home Depot or get fancier kinds online. My heart goes out to all of
