This is PDFKit, not Skim. All we do is show the whole view in full screen, on a black window background. The whole PDF display, and certainly anything white, is from PDFKit. (You would not see this in Preview, because that does not use PDFKit to display in full screen mode AFAIK.) My guess that it is a rounding error, as PDFKit always tries to make the (white) page background align with the pixels to make the edges sharp, and any (dark) background is drawn at the exact (non-aligned) page size. That didn't use to be a problem, because they rounded off the white background by shrinking it to the nearest pixel, so the background from the PDF would always cover it. I don't know if this is the case, but perhaps in Mavericks they changed that and are now expanding it to the nearest pixel (that would be the easy way of doing it, because the system has a standard function for doing that). that could explain a 1px white margin on a page edge. If that is true, I would consider that a regression (bug?) in PDFKit. BTW, if this is true you probably would not see the margin when you go to actual size in presentation mode (go to the bottom of the screen.)
