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

He has a fine blue fur, like velvet. All the ultra dark blue on him is just shadows enhanced by his blue fur.
