You don’t have to have some type of skin malady to benefit from an oatmeal bath. Just as breakfast oatmeal soaks up milk, finely ground oatmeal in the bath can absorb oil, dirt and their resulting odors. In addition, oatmeal has a high pH level, meaning it’s less acidic, while dry, itchy skin often has a low pH level, which means it’s more acidic. The offsetting pH levels neutralize each other, which helps you literally feel more comfortable in your own skin. You may also notice that your skin is softer and better moisturized. Having soft skin also has an added benefit: It’s more effective at warding off exterior irritants.
