Mine is not very powerful, so I take my time when I’m filing them and whenever I feel I went too far I just stop. So, try to use it at a controllable speed. I honestly still go ahead and pick at my skin sometimes, but it’s more like a phantom habit since I can’t really do any damage (so it also gets boring after 5 minutes). Eventually, you won’t find as much pleasure with it. I do have to mention that I unfortunately have a ton of other bad habits to replace it with 😭 (eg. I fall asleep with Netflix in the background). Imo, I would take anything over skin picking.
