Our tip for red, itchy, inflamed skin – colloidal oatmeal. Colloidal oatmeal is simply oats ground into an extremely fine powder. When added to bathwater, it creates a milky dispersion that prevents the oatmeal from settling rapidly. So the oatmeal stays in the water and doesn’t just sink to the bottom of the bath. When you get into the tub, the colloidal oatmeal feels silky, as it coats, moisturizes, softens, and protects your skin. To target specific areas, you can even make a paste mixed with water and apply it to your skin like a mask. You can make your own colloidal oatmeal if you like by grinding oats in a food processor/herb grinder.
