Studies have shown that olive oil is not only an effective moisturizer, but that it also can alleviate the symptoms of skin conditions like rosacea, psoriasis, dermatitis and eczema. It can even help reduce inflammation and soothe and heal burns. Most promising of all is that thanks to the high level of antioxidants it contains, olive oil has been shown to greatly reduce tumor frequency from UVB rays.
