From a recent Miriam Webster Word of the Day: 

LOOKISM  \LOOK-iz-um\   noun
: prejudice or discrimination based on physical appearance and 
especially physical appearance believed to fall short of societal notions
 of beauty

As a teacher, Kim's response to recent studies showing that attractive 
students receive better grades was to try to be vigilant against her own
possible lookism.

"We now so expect 'lookism' that the novelty in TV is shows specifically 
designed to get around it. On the already popular 'The Voice', judges listen 
to the singers with their backs turned — deliberately cutting them off from 
the psychological trick that beauty does to the brain." 
(From an article by Sarah MacDonald)

Did you know?
There are a lot of -isms in the English language but most people overlook
"lookism." It describes the prejudice or discrimination people have toward 
others because of their appearances. People first used the word in the late 
1970s in reference to how people were viewing others who were heavier set. 
Today the panorama of "lookism" extends from the "overly" beautiful actor or 
actress to the homely child. Economists, sociologists, and psychologists alike 
pay close attention to the lookism that occurs in everyday life and examine how 
it affects people and society as a whole.

Have you (like I) always been a sucker for a pretty face?  I have to admit that I have, 
but I like to think I am beyond that now, and look for the good in people, not just their 
beauty (or the lack of it.) Still, I am drawn to pretty people in the beginning, and then
hope they prove worthy of that I was once friends with a woman who 
told me that she was not interested in good-looking men, because they always
turned out to be lousy in some way (and egotistical), while the men who were average
looking were generally more interesting, better conversationalists and more loyal. What's 
your experience?
