Facial symmetry is one specific measure of bodily asymmetry. Along with traits such as averageness and youthfulness it influences judgements of aesthetic traits of physical attractiveness and beauty. It is also associated with health and genetic fitness. Facial symmetry has been suggested as a possible physical manifestation of the 'big-five' personality traits. For example, it is found that extraversion and openness are strongly associated with the symmetry of the face. 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. Facial bilateral symmetry is measured via fluctuating asymmetry of the face comparing random differences in facial features of the two sides of the face that develop and accumulate throughout lifetime as a result of stressors.
