When I think about Argan oil, supermodel and skin care guru Josie Maran immediately comes to mind. Her entire line is based around this miracle ingredient -- and her perfect complexion is proof of how well the stuff works. The oil contains a high concentration of vitamin E and fatty acids, and it's more stable in sunlight than other antioxidants -- so it's perfect to wear during the day. It's also very rare and expensive -- so it's a good thing that you only need a tiny amount for it to be effective. "If you see 1 ounce of Argan for $15 that's not right," says Wong. She adds that these cheaper versions may have added ingredients that make them less effective.
