5. Bad Diet
The skin needs proper nutrition in order to replace the dead skin cells with new, smoother, healthier ones. Of course, your entire body needs proper nutrition. But the skin shows signs of an improper diet long before the liver does. When did you see an ugly, unhealthy liver anyway? I have seen a lot of ugly skin.
Look for the food pyramid put out by the United States government. Stick to this and you will be fine overall.
