Dove has been running their Real Beauty campaign for almost a full decade now. The whole goal of the campaign is to celebrate the human body as it is, without relying on the usual touchups and exaggerations found in most beauty campaigns.
For this portion of the Real Beauty campaign, Dove anonymously (at first, they've since taken credit) uploaded a Photoshop action that they promised would add a skin glow to pictures. Instead, the action would undo all the touch up actions that the artist had done up to that point. It's pretty jarring in a beautiful way to see a picture of a model get back their curves. Of course, since Dove isn't comprised of malicious hackers, the Photoshop action also informed the artists how to undo the changes as well.
