Some eczema is hereditary and called atopic dermatitis while another kind of eczema is due to dry skin. However, in all types of eczema, maintaining the hydration of the skin is imperative. Using creams (rather than lotions) within 3 minutes of your shower each day is a great way to rehydrate the skin and prevent eczema. However, if you are still experiencing issues, see your dermatologist to offer prescriptions that can help.
