What are the best vitamins to help with dry skin and wrinkles?

Vitamin C is great: Vitamin c serum is a great antioxidant that helps protect against sun damage and improves dry and irritated skin. It is the only antioxidant vitamin that is more effective if placed on the skin rather than taken by mouth. It is important to get a vitamin c serum that is correctly formulated. The best ones come in a dark bottle with a dropper (light and air cause the product to break down).
