Twice as many girls are unhappy with their apperance than boys, according to a new study.

It finds 17 per cent of girls aged 10 to 15 don't like how they look, compared to just 8 per cent of boys that age.

Researchers think it's made worse by the pressures of social media, like facebook or snapchat.

Although 68 per cent of girls are still happy with their appearance, and 79 per cent of boys.
