I am looking for a word or succinct descriptor for a person whose appearance has changed such that they are no longer found to be physically attractive by the speaker/writer.
The ideal answer should be gender-neutral (or readily gender-flexible) and avoid the implication that the essential "worth" of the person in question has somehow changed because the speaker/writer no longer finds them physically attractive. The purpose is simply to note the fact of the event, not make a value statement about it.
