If you mean Momon's "face" (the illusion) there is no mention of it in the LN, at least I didn't found any by the time he has a masked dance with Demiurgue.

It is however very likely he uses a japanese face on purpose in order to justify Momon's "always helmet on" (aside from being a nod to all RPG gamers, both in computers and P&P, who avoid removing a single piece of equipment unless forced by events -usually quests or GMs-). Since the author prefers to leave the "rules" as vague as possible (it is a smart move: you can't paint yourself onto a corner if the "rules" are a little vague), the chances are equal between Ainz's "IRL" face and someone whose face he can't forget (father, brother, or even boss), it stands to reason that the only requirement is for him to remember that face perfectly.
