As you can see, she already looks like a zombie (or a sexy vampire) but I fell it lacks realism (well, as much realism as you can talk about, of course, in a horror movie character). She doesn’t have any stains, any spots. So, I gave her that. I chose the same Burn tool, set the Range to Shadows and Exposure to 50%, and put some spot and stains around. Of course, I could not have forget the 2 little spots on the neck, where she was bitten.

Well, this is the final result. You can do some more playing around with the tools, but I leave this to your imagination.
