A new fad — Dietary drinks that promise reduced wrinkles to a clear complexion, but some dietitians aren't convinced. From the New York Daily News: Fountain drink of youth sounds good, but there's a wrinkle:

The newest on the market is Glowelle, which was launched at Bergdorf Goodman and Neiman Marcus earlier this week. Not yet tested by the FDA, it claims to "help fight the signs of aging" and promote an "overall dewy glow" with the help of antioxidants.

"Some people see a difference within a couple of weeks," says Dr. Susan Beck, one of the experts behind Glowelle, who says she takes it regularly and formulated it to work alongside multivitamins and topical skin creams.

Although doctors agree that drinking fluids is important for good skin, dietitians argue the science behind the new beauty drinks is unfounded.

"There is no good evidence that antioxidant-spiked beverages confer any real health benefits," says American Dietetic Association spokeswoman, Sari Greaves, who warns that you should always talk to your doctor before taking any new supplements.
