There's a science to being hot.
So I'd imagine there's a science to being unattractive (to most people).
There are def certain features that are unattractive and we all know what they are. But sometimes I'd see two people with similar features. But one's hot, one isn't. Then there are people with conventionally unattractive individual features that look HOT.
A lot of it's about how the features mesh. Bone structure, symmetry, etc are quite important.
I think one thing that people overlook is facial expressions. Though that's not innate. There's one K-celeb that's known for being ugly even though his/her facial features individually aren't that bad.
And I think the fact that his/her facial expressions and smiles are really fake makes him/her less attractive. Though this person wasn't good looking to begin with.
What do you think?
