The bestselling product in supermodel Josie Maran's eponymous line is the multi-purpose, 100 percent pure Josie Maran Argan Oil
, $48. Since it was released, it's developed a cult following, and Maran has responded to its popularity by creating complementary products like cleansing oil and bronzing oil. "But I still wanted to do more
with Argan," she said. So she had the idea to team up with two other supermodels -- Petra Nemcova and Angela Lindvall -- to design the packaging for limited edition bottles with proceeds benefiting a charity that's special to each of them. When asked which bottle she thinks will be most successful, she smiled and said, "I hope the collectors will get all three."
