Britain's Girl Guide Association is calling for the government to make the labelling of "touched-up" images in the media mandatory.
Girlguiding UK claims that the photoshopped images have a "devastating" effect on young women in Britain.
A recent survey conducted by Girlguiding UK found that 50 per cent of the 1,109 16 to 21 year old women surveyed are considering having plastic surgery to change how they look.
The survey also found that 42 per cent of 11 to 16 year olds are overly cautious of what they eat.
Girlguiding UK's Head Guide Liz Burnley said: “We know how profoundly they feel the pressure to conform to a particular body image and how badly they can be affected by these unobtainable ideals.”
"We are proud to support the calls of our members who believe that it is time that the prime minister addressed their concerns and acted in the interests of girls and young women across the country."
Writing on the Girlguiding UK blog, the group said that it will launching an online petition, starting 5 August, to highlight their cause.
Girlguiding UK expects the petition to be signed by around 20,000 young women.
