A 1% colloidal oatmeal eczema cream cut eczema severity scores in half over 14 days—beating a standard moisturizer. It also helped restore healthy skin bacteria diversity and improved skin barrier function, pH, and hydration, while the regular moisturizer only helped with dryness.

61 people with mild to moderate eczema were randomly split into two groups: one used a 1% colloidal oatmeal cream, the other used a standard moisturizer. Researchers measured severity, skin health markers, and bacteria composition at day 14.
