I was wondering, how do i get rid of the dirt/burnt face bug on my vampire?

the only "fix" so far is to remove all dirt, eyeliner, eyeshadow, cheek and forehead color. If you're already a vamp then you have to cure yourself in order to fix your face at the face sculptor in riften and then ask serana to turn you again or contract it the way you did before dawnguard. There's no player fix for the lip line though
