Colloidal Oatmeal is a pretty amazing ingredient when it comes to treating eczema. When oatmeal is has been ground and then suspended in liquid, it’s known as colloidal oatmeal. This method allows the oatmeal to be more easily absorbed into the skin, which helps it to become even more effective at protecting and soothing. The ingredients in colloidal contain avenacins compounds, which have antifungal properties; saponins, which can help in cleansing; and flavonoids, which might help with absorbing ultraviolet-A (UVA) rays. It also includes vitamin E, which is an anti-inflammatory, along with phenols and starches to help in moisturizing.
What makes it effective at soothing the skin is the cellulose and fiber from the oats. These make a skin-softening emollient that is effective against irritation and redness that comes from conditions such as eczema and rosacea. When skin is soothed, the itching usually is relieved as well. As a skin protectant, Colloidal Oatmeal temporarily protects injured or exposed skin from harmful or annoying stimuli, and may therefore provide relief to the skin. Avena Sativa (Oat) Kernel Meal and Colloidal Oatmeal also function as abrasives, absorbents and bulking agents.
