Cosmetic adverts featuring airbrushed images of actress Julia Roberts and model Christy Turlington have been banned by the advertising watchdog.
Liberal Democrat MP Jo Swinson complained that the L'Oreal adverts were "not representative of the results the products could achieve".
The Advertising Standards Authority agreed that the images were exaggerated and breached its code of conduct.
L'Oreal admitted retouching but denied that the two adverts were misleading.
