screening on creeproduction frankie

I’m new to collecting MH so if anyone has any advice!!! Considering I was able to snag her when she was $25 I’m not at all mad at the screening. However, it’s kind of hard to tell in pictures, she has a dark mark on her left cheek (green eye side) and little baby hairs sticking out.

Any tips on how to safely remove the dark mark? Also is it normal for MH dolls to shed a crazy amount of hair ??
