Well,
I think teeth are a natural, and almost permanent, unvarying facial recognition item.
Dental records are used a lot to identify so there's that as well.
Those dentists are always pushing a full 3d scan of people's teeth so there you go.
Flesh can vary a lot more, depending on year and edema (water load, etc.).
Retina scans or eye features are very good, but that probably can't happen if farther than 5 -10 feet or so.
That's where one's gate comes into play.
Identification is made at farther distances via someone's walking gate.
