"For the young, social media filters that smooth skin and inflate their eyes’ proportions are almost ubiquitous, like a popular 'Pixar' filter on Snapchat..."

"... that made its users look like the cartoons of their youth, or the popular Facetune app. It is a short leap to 'Facetuning' in real life. Patients used to approach surgeons with photos of celebrities; now it is more likely of their own filtered face. 'It’s exceptional now to see a photo on social media without a filter,' [says Dr Olivier Amar, one of London’s leading cosmetic surgeons]. 'Patients are comparing themselves to something that doesn’t exist. And because they may only ever see themselves on a phone, using their phone as a mirror, they may not even recognise themselves in a real mirror. If they get these treatments they feel they can have the life as people seem to have online.' Why, then, has this 'bug-eyed' face emerged ahead of all the other cultural standards of beauty? David Bainbridge, a reproductive biologist at the University of Cambridge, wrote in his book Curvology that females are more evolved than males: humans have smaller teeth, flatter faces, smaller chins and less hair than primates, especially females. Many of these qualities are emphasised in 'Instagram face,' the distinctive narrow-nosed 'heart-shaped' face. 'We do not know why women should be more "modern-looking" than men,' Bainbridge writes, 'but it has been suggested that many of the characteristics men find attractive are the same as those which make them look distinctively human.'"

From "Love Island and how young people fell for cosmetic surgery/A surgeon says women want an ‘alien’ face: sharp cheekbones and big lips. Why?" (London Times). "Love Island" is a British reality TV show. 

The term "alien face" is used in the article. It's a reference back to cheesy 1950s movies and has to do with "diagonally pulled-up eyes... narrow nostrils and a glazed, expressionless stare" or something like "the image on the front of Space Raiders crisps, this kind of overbuilt cheek, overbuilt temple, skeletonised, sharp features that just didn’t look correct."

It's interesting to take that observation and extrapolate a reason why so many people would decide that's the most beautiful look. So Bainbridge offers his theory, that we somehow aspire to more and more evolution and are projecting into the future, trying to look like humans a million years from now. How do you know where evolution will take us? 

It seems as though you take your cliché image of a caveman, imagine what is needed to get from that to standard human being of today, then whatever you just did to the caveman, do it again to the person of today, and that's the ultra-evolved human being. Or — to follow Bainbridge's idea — you accept that a woman of today already has that "more evolved" look, so you plot a straight line from modern man to modern woman and keep going. What do you see? Now, get a plastic surgeon to translate that fanciful vision onto your actual face. 

Won't you look weird? Not if you've been using your phone as a mirror.
