If Jesus existed as a single person, which is highly doubtful, then it is certain that none of the images of him that are currently popular have any relationship to his actual appearance.
Why an image made 400 years after his death is better than one made 1400 years afterward is beyond me.
Could you draw a likeness of Oliver Cromwell that his friends and family would have recognised?
As to the idea that a beard is an important characteristic of a man's appearance, I can tell you that I have worn a beard most of my adult life; but there have been times when I shaved it off, and I once had a passport that for eight years showed me as clean-shaven when in fact I had a beard.
In summary, who cares. Even if we did care what Jesus looked like, this finding tells us fuck all about his appearance.
