Just pick the nail polish off your skin. When you paint your nails with expensive nail polish, it comes off your skin, mostly, at least with some. Apply more than 1 coat; I've always used 1 or 2. I've never tried 3 that I remember on nail polish that was opaque enough. If you use less expensive nail polish, I think you just pick at the nail polish that gets on your skin and that it comes off your skin on its own after a day.
