I think if you're beautiful, you're always going to be objectified in some way, but if you had a perfect face, at least people would speak about that in more spiritual terms, of the 'soul' they could see in your gaze, or the timeless grace of your bone structure - whereas having a great body often leads to someone being treated as a piece of meat. I certainly know I'd rather people look into my eyes than stare elsewhere...
And while a less-than-perfect body can be dressed in ways that compensate for the flaws, your face is on show all the time, and even the best haircut can only do so much for your features.
