I have 3 fidget cubes (one at the office, one at home, and one in the car) and they've all worked wonders. I usually pull the skin off my lower lip, the skin around my fingers, and pull my eyelashes out. I'm happy to say that atm I have one cut on my finger, my lower lip has one layer of skin missing, and my eyelashes are full again. If my hands are busy playing with the cubes they're not picking at my body and it's really helped me.
