If your skin is drier than the Sahara, start stocking up on oils. "Dry skin is actually a manifestation of chronic subclinical (invisible to the eye) inflammation," says Perricone. "Make sure that you have adequate intake of healthy fats, such as those found in fish, fish oil, and extra virgin olive oil. While topicals can do wonders [for dry skin] it is critically important to not forget the dietary component, which can both cause and worsen all of these conditions."
