Colloidal oatmeal is created from finely ground oats. Colloidal oatmeal can help reduce irritation and dryness. Because of its well-known anti-inflammatory and antioxidant effects, it helps to lessen skin irritability. The usefulness of colloidal oatmeal in reducing itchy skin has been demonstrated in numerous studies.
In a 2015 study, healthy women with mild to moderate irritation experienced less scaling, roughness, dryness, and itching intensity. Another study carried out in 2016 discovered that colloidal oatmeal is safe and aids in treating itching and moisture loss, in addition to assisting in enhancing the skin barrier.
Meanwhile, a 2020 study discovered that one percent colloidal oatmeal added to a topical lotion enhanced skin. The study found that the participants that received the one percent colloidal oat cream improved significantly in skin barrier function, hydration, and pH, whereas the participants that obtained the regular moisturizer improved mainly in hydration.
Colloidal oatmeal is widely available at pharmacies. Alternatively, you can create your own by powdering oats. Consider taking an oatmeal bath for a more severe, broad rash or relieving sunburn symptoms or hives. It should be slowly added to lukewarm water while being stirred every so often to prevent it from sticking to the bottom of the tub.
