It is recommended to use a moisturizing cream like La Roche-Posay cicaplast baume B5 for red patches of eczema. If moisturizing creams are not effective, a low-potency cortisone cream may be necessary, which can be bought over-the-counter at a pharmacy or prescribed by a doctor. Other measures to help with eczema include using soap substitutes, keeping the skin moisturized with creams or petroleum jelly, applying moisturizers after bathing, taking baths only once a day, using colloidal oatmeal in bathwater, and patting the skin dry after bathing.
