"You can look significantly younger just by keeping your skin hydrated," says Howard Murad, M.D., associate clinical professor of medicine at the University of California, Los Angeles, and author of The Water Secret: The Cellular Breakthrough to Look and Feel 10 Years Younger. "Water naturally plumps skin, fills in fine lines and wrinkles, and boosts a lackluster complexion." He recommends drinking lots of water (the Institute of Medicine's most recent water-intake guidelines suggest 11 8-ounce glasses of water a day) and using products on the skin that contain hyaluronic acid, which creates a moisture barrier, helping it hold on to water longer.
To make sure your tap water is safe, visit EWG.org, which houses water-safety ratings of cities across the country. If you live in a place with a bad rating, if your home is older and has lead pipes, or even if you just don't like the taste of your tap water, use a filter, like the Brita On Tap Faucet Mount Filtration System.
