A Natalie Portman ad for a Christian Dior mascara has been banned for exaggerating the effect of the product on her lashes.
The 31-year-old is the face of Dior mascara that claims to deliver "spectacular volume-multiplying effect, lash by lash".
But rival company L'Oreal complained to the Advertising Standards Authority (ASA), arguing that the ad was misleading and it is unlikely that the product would give such effects, reports mirror.co.uk.
The magazine ad shows a picture of Portman with the text: "Lash-multiplying effect volume and care mascara. The miracle of a nano brush for an unrivalled lash creator effect. It delivers spectacular volume-multiplying effect, lash by lash."
Bosses at Dior admitted that the image had been digitally retouched, saying it was done to "increase the length and curve of a number of lashes" as some of the actress's eyelashes were "missing or damaged" in the original photo.
Following the complain, authorities at ASA banned the ad from being used again, saying it was misleading and exaggerated the effects of the mascara.
