The film, Onslaught, is a powerful and disturbing illustration of how young women will go to any length to get the 'right look', ranging from Bulimia to plastic surgery.
It also highlights the vulnerability of children to advertising and explains why a new set of Children's Rights and Business Principles, created by UNICEF, Save the Children and the United Nations Global Compact, urges business to use marketing and advertising responsibly.
The principles say companies need to recognise children's greater susceptibility to manipulation, and the effects of using unrealistic or sexualised body images and stereotypes.
Keith Weed, chief marketing officer at the multinational consumer goods company, is under no illusion that advertising has a powerful influence on the way we live our lives. He should know, given that Unilever is the second largest advertiser in the world.
"There was an argument in the 80s that advertising just moves consumption around. I don't believe that," says Weed. "We need to make sure that children are brought up in a way that respects and develops them. Advertising has a responsibility. We can create positive imagery but also can create negative imagery."
