And speaking of facial asymmetry...

As best I can tell, the photo above shows an intentional cosmetic enhancement, not a congenital defect.  Here's the relevant text:

what exactly is it? just a combo of circle lenses, and fake eyelashes or what?? i want some
 as far as i can tell, it’s circle lashes and falsies
it’s amazing what a little makeup can do, huh?
yea. Oh man i kinda want to try the circle lenses, even though theyre creepy 90% of the time and i hate wearing contacts cause i always get makeup in them. But having huge eyes like that would be cool...

So I'm assuming that the process would then be repeated on the left side to finish the modification of the face, not left asymmetric as a new Goth fashion...

Via No.

Addendum: A big hat tip to an anonymous commenter, who knew that "this was part of a taiwanese variety show where the objective was to show how plain a couple of internet models were before they applied makeup, and ended up being a competition for most dramatic difference." 

Here's a link to the YouTube video from which the above is a screencap.
