This just in: The fountain of youth is only $120 ... and includes free shipping!

New York perfumer Harvey Prince just released Ageless Fantasy, a grapefruit-scented fragrance promoted as "the world's first anti-age perfume."

The claim is nothing to (bad pun ahead!) sniff at, either: According to the manufacturer, spritzing the perfume on will make you smell eight years younger.

The formula is based on actual research by the Smell and Taste Treatment & Research Foundation. Its researchers smeared middle-aged women with scents like banana, broccoli, spearmint and lavender, then asked male volunteers to sniff them and guess their ages. Grapefruit-scented women were guessed to be considerably younger than they really were -- about six years, on average.

The idea to turn this insight into a perfume was simple, says the flack at Harvey Prince. "Just like 'rose' scents read 'old lady,' there had to be a fragrance that reads 'young lady.'"
