Strange "Shadow-Lines" on the skin

[Brogud]

Hello everybody,

 

I've run into a strange Problem, to see what I mean just look at the Screenshots provided with this mod: http://skyrim.nexusmods.com/mods/22743

I didn't pick this particular mod on purpose, it's just an example because I noticed the exact problems I'm experiencing!

You can see it very clearly in picture 3 and 12. Take a look at her face. So, what's causing this problem? If you need more information, just ask.

 

Thanks for your help!

 

Greetings
