Evolutionary biologists note that a symmetrical face is more attractive around the world because symmetry signals good genes for reproductive health.

Facial symmetry

https://en.m.wikipedia.org/wiki/Facial_symmetry

Facial symmetry is one specific measure of bodily asymmetry. Along with traits such as averageness and youthfulness it influences judgments of aesthetic traits of physical attractiveness and beauty.^[1] For instance, in mate selection, people have been shown to have a preference for symmetry.^[2][3]  This is because it is seen an indicator of health and genetic fitness,^[3] but also as holding adaptation qualities; reflecting the ability to withstand the changes in their environments.^[4]

Facial symmetry has been suggested as a possible physical manifestation of the 'big-five' personality traits.^[5] For example, it is found that extraversion and openness are strongly associated with the symmetry of the face.^[5] Hormones such as testosterone and estrogen are believed to be associated with developmental processes and growth of facial features during puberty and as a result are hypothesized to be the cause for individual differences in the implications associated with facial symmetry
