However, other studies showed that both symmetric and slightly asymmetric faces are considered attractive. Here we aim to explore this discrepancy, beginning with the analysis of the normal prevalence of facial symmetry in a population as a necessary first step prior to any attractiveness assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We collected facial landmarks from two\u2010dimensional digital images of a sample of Mexican individuals (280 females and 285 males aged 18\u201368 years) that were analyzed using geometric morphometric methods. Then, we chose a subsample of 100 photographs (50 females and 50 males aged 18\u201327 years) selected to represent a broad range of asymmetrical variation, in order to evaluate attractiveness using a sex\u2010opposite test. Finally, we analyzed the linear correlation between attractiveness and asymmetry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found that every evaluated subject presents some degree of facial asymmetry, and that both fluctuating asymmetry and directional asymmetry were significant (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001) components of total facial asymmetry. Fluctuating asymmetry was slightly associated with age (<jats:italic>r<\/jats:italic>\u2009=\u20090.0858,<jats:italic>P<\/jats:italic>\u2009=\u20090.0414) and there were no differences between geographical regions (<jats:italic>P<\/jats:italic>\u2009=\u20090.413).
