Colloidal oatmeal is created by carefully grinding or milling oat kernels (Avena Sativa). The bran in the oat kernels is still present, and it contains vital skin soothing actives that bond to the skin to form a soothing protective barrier. Colloidal oatmeal, a natural substance with established barrier protection, moisturization, anti-inflammatory, and calming characteristics, has been shown in studies to help with eczema symptoms.
