As a skin picker, one of the best tools you can use are fidget toys. In therapy, I learned that my hands need an immediate response to replace picking. Keeping my hands busy is important to avoiding picking.
So, I tried a number of different fidget toys. But my favorite by far are Bucky Balls. They are tiny little magnetic balls, that you can do anything with.
You can make them into a big string, a square, or just squish them together. It sort of feels like putty, except they are tiny balls.
You just can't put them down. I hold on to them at night, when watching TV.
If you're a skin picker and need a good fidget toy, I can't recommend Bucky Balls enough.
Buy them at local stores, for about $29, or at their website, GetBuckyBalls.com
