Video · What Exactly Does a L'Oreal Ambassador Do at the Cannes Film Festival?

This year marks L’Oreal’s 18th as the beauty sponsor of Cannes. And the international giant’s ambassadors — actresses and models from around the world, most of whom appear in print and TV ads — are the best way to promote the brand. This year, Andie MacDowell, Eva Longoria, Julianne Moore and Naomi Watts among others will hit the Palais carpet. Each will report for duty for up to five days, including ad work and social media participation.
