Sugar-water seller Coke, and cosmetics giant L'Oreal, are reportedly working on a new beverage currently called Lumaé, which they will sell as a soft drink that promotes healthy skin via some yet-undisclosed ingredient. The beverage may be sold in department stores, rather than convenience and grocery outlets. Both soft drink and cosmetics companies in general want to cash in on what they see as a coming boom in "nutraceutical" beverages. "Pretty soon there will be a drink for every part of the body and every mood you're in," said Larry Trachtenbroit, head of Brain-Twist, New York. My view: If you want healthy looking skin, then be healthy all over, inside and out. And that means eating a healthy diet -- and drinking plenty of water.
