Keep fingernails short. Put on a pair of gloves to protect your hands. Use a fidget toy to keep your hands busy. Draw or write to keep your hands engaged. The best thing you can do is use moisturizer instead of picking. Apply ointment to any sore areas. Request that others keep a watch on you. Maintain a healthy stress level. Stay away from your triggers. If you're having trouble quitting on your own, talk to a therapist. If you require additional assistance, consult a doctor about prescription options.
