Mick Jagger's daughter has become the latest face of a misleading beauty campaign.
Rimmel exaggerated the benefits of a mascara by pinning false eyelashes on Georgia May Jagger, the singer's daughter by Jerry Hall, the British Advertising Standards Authority (ASA) ruled.
Banning the TV and magazine ads, the ASA said the use of false eyelashes had exaggerated the effectiveness of 1-2-3 Looks Mascara and complained Rimmel's research about its benefits had only been conducted on five women.
A string of ads starring models and actresses have been banned in the past five years for duping the public about the efficacy of skin creams and eye products.
Last December, the ASA censured Procter & Gamble for airbrushing ads in which the Sixties model Twiggy hailed Olay Definity eye cream as her "secret to brighter-looking eyes".
Three years ago another Rimmel ad for mascara was banned for digitally enhancing Kate Moss's eyelashes. The ASA added Rimmel had failed to prove the campaign had shown the model's own eyelashes. And the same year L'Oreal -- whose claims for a wrinkle cream promoted by Claudia Schiffer were banned by the ASA in 2005 -- was criticised for using a picture of Penelope Cruz in false eyelashes to promote mascara.
In June, however, Cheryl Cole escaped trouble when the ASA rejected complaints that she should not have advertised L'Oreal shampoo while wearing hair extensions.
The rulings come amid growing controversy over the depiction of women in beauty ads, which campaigners claim make ordinary women feel bad about themselves by depicting unattainable looks.
Rimmel's latest adverts, for 1-2-3 Looks Mascara, focused on the eyes of 28-year-old Georgia May Jagger.
To highlight the eyelash thickener's different settings, they advised women they could achieve "three hot looks in one mascara", and close-ups showed Ms Jagger's eyelashes appearing to increase with each "look". But the ASA discovered that each "look" was achieved using false eyelashes rather than the model's own.
Rimmel's owner Coty UK said it had used false eyelashes "to ensure a consistent and aesthetic lash look", not to present an exaggerated or unachievable look. A small print below the ads stating "shot with lash inserts" should have been enough to alert the public to the use of false eyelashes, the company added.
