I know — we all get it, celeb pictures are Photoshopped. But I still believe that even though we know this, constantly seeing the end product without catching a glimpse of the "before" results in unrealistic ideals. And I think this is especially true for kids and teens.
Some of these are pretty extreme. +1 for Photoshop skills, -10 for realistic expectations.
Note that not all of these "after" images were published in magazines. While some certainly were — Kourtney Kardashian was not pleased about the the work OK magazine did on her photo — others were Photoshopped by random people after they were published.
