You could put something on your fingertips, though most lotions don't work well and the ones that do are oily and you smear everything you touch. Olive oil would work well, if you have a couple hours during the day where you don't have to touch anything with your left hand. You could apply it before you go to bed and wear a cotton glove so you don't grease your sheets. My wife has some stuff from Burt's Bees that she applies at night and wears gloves with. It's supposed to fix dry skin.
