As a Goodwill Ambassador for the United Nations Refugee Agency, actress Angelina Jolie has visited developing countries in all corners of the globe. Even though those places may lack for running water, Jolie never lacks for a beautiful complexion. One possible reason? She allegedly uses creams by La Prairie that are packed with caviar [source: Yaqoob]. While most of us eat any caviar that's put in front of us, La Prairie takes the yolk sac from sturgeon eggs and put it in their products; it's believed that the fatty acids in the yolk sac soften and regenerate skin. The product is also reportedly used by Mick Jagger, Gwyneth Paltrow and Stella McCartney [source: Yaqoob]. No word on whether Jolie's partner, Brad Pitt, also uses the product, though on the next page, we'll discuss someone who's probably familiar with his grooming habits.
