One of the peculiarities of the Resurrection is that some acquaintances didn't immediately recognize Jesus (e.g. Jn 20:14-15; cf. Lk 24:16ff.).
The Emmaus road incident is easier to explain due to God temporarily inhibiting their perception. But what about a case like Mary Magdalene?
One explanation may be the nature of the Resurrection itself. Glorification has the capacity to repair and rejuvenate. It depends on the condition of the individual when they died.
If a Christian dies of brain cancer, God won't resurrect him with brain cancer. If a Christian dies at 90, God won't resurrect him at 90.
The glorified body is youthful and ageless. In the world to come, the saints will no longer experience illness and senescence.
Jesus was in his early 30s when he died. He spent lots of time out of doors in direct sunlight. When he was on the road, he probably slept out of doors. In addition to hot summers, Israel can have freezing winters.
So his complexion was weatherbeaten. And by that time he may have had thinning hair or graying hair. In any event, he probably looked older than he would with less exposure to the harsh elements.
But one effect of the Resurrection was to rejuvenate him. His acquaintances wouldn't expect Jesus to appear significantly younger.
