Not sure if any one else has encountered this problem but Nathalia Poppyflower in the Undercity has the grey face bug, at first I assumed it was because of my CBBE Body replacer but I removed my mods and she still has a grey face -- she is the only npc I've noticed so far.
Please submit a ticket at our bugtracker for these kind of issues. Thanks.
