It is possible to sever the face off of anything that has one, creating a gruesome mask that can be worn over your own face. This grisly trophy provides a boost to your ego from +1 to +3 when equipped and changes your relationship with the creature's faction or factions by -500. You can also have your own face severed, and while this also provides the same ego boost if worn without any faction relation drop, you need to have regrown a new face using an ubernostrum injector, through the regeneration mutation or have a second head to do this.
Some creatures have a different name for their "face", but which still functions this way when severed (and is described as their face in the item details).
Be careful when interacting with face items in your Equipment screen, since unlike most other equipment, the default action for them isn't "remove", but "eat".
