Contact/irritant. If you have dry skin, you will need to use a thick moisturizer after washing your hands whenever possible. Wear vinyl glove when washing dishes or anything else. Avoid scented soap of any kind. After washing hands before going to bed, apply some moisturizer on the hands and wear non-latex gloves overnight. Consider getting patch testing to find out whether contact allergen plays a role.
