[Danaus29]

Put some O'Keeffe's working hands salve (it comes in a round, green plastic jar) on your fingers and hands. It will burn a bit but it helps to heal the skin a bit faster. Wear some thin, cotton gloves and get some sort of toy like a fidget spinner to play with instead of picking your fingers.

It's a bad habit but it can be broken. I used to pick my lips. It took me years to stop but I did stop.
