is part of Changing Faces' "Face equality" campaign, which aims to ensure that people with disfigurements are treated fairly and equally, irrespective of their facial appearance.
The spot, produced by Feel Films, is shot from the perspective of the girl with a facial disfigurement, showing how a variety of people react to her on her journey to work.
At the end of the ad, her face is revealed and she delivers the line: "You might not notice what you are doing, but I do."
It was shot on 35mm film to give a cinematic, warm quality to the observational style.
The ad has been uploaded on YouTube and is being communicated virally through Facebook and email as part of a wider campaign. This includes TV, print, viral and a complete redesign of the charity's website.
It will be aired on TV in the coming weeks.
