I'm not a big fan of makeup normally, but when used as adornment (like ribbons or beads), I think it's awesome. Like little symbols or like a fang looking mark under the eye.

It seems like a lot of this isn't tagged, and what is is under a lot of different tags. I would suggest a couple aliases, but I'm not sure the best way to do it since I don't even know what exactly to call it. "facial_marking" seems the best to me, but I see facial_mark, facial_markings with higher count.

Any other names this goes by? Anybody have ideas on how to or want just go ahead and set up aliases?

A few examples:
gelbooru.com/index.php?page=post&s=view&id=521571
gelbooru.com/index.php?page=post&s=view&id=374848
gelbooru.com/index.php?page=post&s=view&id=169617

First make facial_mark an alias of facial_markings and then use facial_markings as the tag for this.
