[Star Wars] Is Vader's mask intentionally made to look intimidating or are those mask styles common?

Granted, we've never seen a similar mask as Vader's, but I was wondering if it was a special mask mold ONLY unique to Vader's, or if it was some traditional sith/usual mask. 

I ask because as a kid I found Vader's face creepy as hell, so I'm wondering if it also had a purpose to instill dread into the people looking at him. Like, if I was Luke and saw Vader in the cave I'd have pissed my pants. Vader may seem badass in hindsight but I can totally see if someone saw him for the first time he'd come off as a scary cyborg monster. His mask just looks creepy.

Iirc one of the legends novels mentioned the mask being based off of traditional sith warrior masks with more modern medical attachments.  Vader and palpatine just never bothered making a friendlier face to the mask since ultimately he was the emperor's fist not his pr guy.
