Facelifts can account for some things but it won't change bony structure.

Look at the width of the nose bridge between his eyes. And the "bend" in the cartilage mid-nose, then the cartilage at the end of his nose. A facelift is not rhinoplasty.

Facelifts do not fix muscular imbalances that caused his crooked smile. This new ventriloquist dummy has a very even and incredibly creepy smile, with no involvement of his eyes. Now, a facelift could cause the latter part, but so can a prosthetic.

Also, Biden had a strong chin and jawline (as much as I hate the man, he had physical "presence" in his facial features). Again, a facelift will not diminish his jawline or jutting chin. This guy had none..and age does not diminish that as drastically as you think.

You simply cannot use "hairline" as a baseline. That's the easiest to change or replicate.

And lastly, the height of his ears is different, where the line from the lateral corner of his eyes intersects the anterior aspect of his ear.

You can see your similarities, I can see the differences. I'm going to leave it at that.
