People say symmetry in a face is beauty?

I kind of know what symmetry is, but can someone explain it in the face? like, what do you mean by symmetry in a face is what makes someone pretty? examples too please thanks :)

and also what isnt symmetry in a face

It means that the face is balanced on both sides.

Not only are both eyes the same shape, but if you cut the lips, nose, and chin in half they are identical. The jaw bones, cheeks, etc. are all identical, plus there is identical spacing on both sides.

If one eye is bigger than the other, it isn't symmetry. The thing is, if there are two of something on a human body, they are never the same size. This goes for ears, eyes, nostrils, girls' upstairs, guys' downstairs, feet, hands, etc.

It doesn't necissarily make them pretty, but it makes a balanced, pleasing type of thing usually.

As the other person said, both sides of the face are exactly the same. As an example, the distance from the outer edge of the eyelid to the nostril will be the same from either eye or the distance from the eyelid crease to the brow will be the same distance from either eye. I saw a show about this years ago. During the test the testers put two pictures on the screen (one face symetrical and the other not symetrical). Babies would stare at the symetrical face which would imply beauty. But look at Heidi Clum (Victoria Secret Model), her eyes are different (one sags) so her face is NOT symetrical but she is still pretty.

I think so that a symmetrical face is a face that its components (eyes, eyebrows...) are exactly alike.

But I have ptosis disease, and it means that One of my eyes looks slightly smaller than the other, and it's not beautiful at all. I don't like it :(

i've heard that too- the face and the body.

wierd.. but, after i thought about it, i think it's true

it means when one side of the face is EXACTLY the same as the other side.

i dont necessarily think a symmetrical face is pretty, but the face itself. i dontknow. it sounds absurd to say that a symmetrical face is pretty, but not others.
