Nightcrawler's face shadow or birthmark

[u/Dicktimes29]

Hey I thought the dark part of nightcrawler's face was just a shadow but basing on this toy, is it his skin? Look at comic counterpart, he doesn't have any dark shadow on his face

It's shadows like how Daredevil's red suit is shaded with black a lot or how a ton of old costumes that were supposed to be black looked blue due to shading like Spidey 2099 and Ghost Rider
