The Beauty Benefits of OatmealThe hype regarding this well known breakfast meal typically focuses on its cholesterol lowering results, but it offers another super benefit. Oatmeal will also relieve rashes and skin irritations triggered by toxic plants, like poison oak and ivy, along with discomfort and itching brought on by sunburn or chicken pox. Just sprinkle a little dry oatmeal into a warm bath then soak in it for around 10 minutes. With its grainy texture, oatmeal works great as a gentle skin exfoliant, just mix it with warm water, put it on your face in circular movements and let it dry for approximately 15 minutes then just rinse if off.
