Colloidal oatmeal also acts as a very mild exfoliating agent. The nice thing about this type of exfoliation is how mild it is. Because the particle size of colloidal oatmeal is so small and relatively soft, it can usually be used on your face and other sensitive areas that traditional exfoliating agents might irritate.
Colloidal oatmeal also has something in it called phenols, which provide it’s anti-inflammatory properties.You’re skin has a pretty complex pH system. You have an acid mantle, which sits on top of your skin and helps protect you from the environment.
This has a pH of about 5. Subsequent layers of skin have differing pH levels. Sometimes products that are too alkaline can throw off the pH of your skin, causing or aggravating certain skin problems. Colloidal oatmeal acts as a pH buffer which helps correct the pH of your skin.
