Well, we shouldn't assume that her appearance equates her physiology.

Secondly, Mrs. F has been around for many many decades. Psychologically speaking, it is justified that she would want to take an older appearance. Not only is she taken more seriously by government officials she has to interact with, she's watched nearly everyone else in her life die. If I was in her position, I could justify looking older in order to feel like less of an immortal.

And Mrs. F never needs to run from danger. She very clearly has the ability to teleport.
