oatmeal, colloidal topical

Action and Spectrum

Actions and Spectrum: 

oatmeal, particularly colloidal oatmeal, is commonly used in topical products due to its beneficial properties for the skin. oatmeal exhibits both soothing and protective actions on the skin. 

• Soothing Action: oatmeal has natural anti-inflammatory properties, which can help calm and soothe various skin conditions. It can relieve itching, irritation, and redness associated with conditions like eczema, psoriasis, and rashes. oatmeal’s soothing action is attributed to its ability to reduce inflammation and itchiness, comforting the skin. 
• Moisturizing Action: oatmeal acts as a moisturizer by forming a protective layer on skin’s surface. This barrier helps to lock in moisture, preventing dryness and maintaining the skin’s natural hydration. oatmeal also contains lipids (fats) that help replenish the skin’s moisture barrier, making it practical for dry and sensitive skin types. 
• Cleansing Action: oatmeal can act as a gentle cleanser because it can absorb dirt, oil, and impurities from the skin’s surface. It can be an alternative to harsher cleansers for people with sensitive/easily irritated skin. 
• Antioxidant Action: oatmeal contains antioxidant compounds such as avenanthramides and vitamin E. These antioxidants help protect the skin from the free radicals, unstable molecules that can damage skin cells and accelerate aging. The antioxidant properties of oatmeal contribute to its overall skin-protective effects. 
• Skin Barrier Repair: oatmeal can assist in repairing the skin barrier, which is key for maintaining healthy skin. The lipids and proteins in oatmeal help reinforce the skin’s natural barrier function, improving its resilience against external irritants and enhancing overall skin health. 

Colloidal oatmeal is finely ground oatmeal suspended in a liquid like water or a lotion base. This oatmeal benefits topical products as it can quickly disperse in water and form a smooth mixture. The colloidal form enhances oatmeal’s ability to adhere to the skin and deliver its beneficial properties effectively.
