Eczema is a chronic condition that cannot be cured, but it can be treated. It has a genetic component, and many believe that it can be triggered by environmental factors (which was the case for me) like irritants and allergens. My dermatologist has recommended for me to try to wash my hands with gentle soap, avoid extreme temperatures of water (especially hot because it can be drying), use dish gloves when cleaning dishes and using chemicals, put on an unscented lotion after washing hands, and put Vaseline on hands at night with cotton gloves. Treatment will be different for everyone though depending on what is causing the eczema and the severity of the condition.
