Experts have now learned that other factors beyond genetics account for aging discrepancies, and these may be diet and vitamin-related. "With the proper care, you can have fabulous skin in your forties, fifties, sixties, and beyond," says Dr. Nicholas Perricone, assistant clinical professor of dermatology at Yale University School of Medicine. A diet lacking in vitamins A, C, E and folic acid, is detrimental to skin. Vitamin C is one of the most important vitamins to skin. As an anti-oxidant, vitamin C hinders the production of a chemical called arachidonic acid, which can lead to the formation of wrinkles. Vitamin C can easily be added to a diet by consuming more vitamin C-rich fruits and vegetables such as strawberries, tomatoes, and red bell peppers. DMAE is another skin-saver that can easily be added to a diet. Found in large amounts in fish, especially salmon, DMAE is not an anti-oxidant but acts like one by stabilising cell membranes and, therefore, preventing the production of arachidonic acid. DMAE is not only effective internally, it can also be applied topically.
