It is said that beauty is in the eye of the beholder.  That is true.  If you don't see yourself as beautify, you will soon hit the wall and others won't see you as beautiful either.  Good food, diet, spiritual life, sex, fun and perspective are key.  Healthy skin requires good oils, vitamins and minerals.  Skin brushing is a must as it helps remove old, dead skin and stimulate the lymphatics and nutrient flow to the skin.  Sun and environmental damage are proportional to one's nutrient and antioxidant levels; the lower they are, the more damage you will sustain.
