Inane things that pique my curiosity

So ocassionally I'll notice a woman (in real life or an actress on a show) who pulls this facial expression when her eyebrows sorta lower, except where they instead raise up near the bridge of her nose, usually to convey something unpleasant or baffling.

I like to think I'm good at expressions, but I can't for the life of me reproduce this.  I wonder if it's something to do with a particular arrangment/tendency of muscles on an individual's brow and only some people will naturally do it, or if perhaps it somehow has something to do with eyebrow pencil extending the eyebrow to a place where it seems to move in an interesting way when the muslces underneath move?
