Which Side of Face is Attractive?
Studies consistently show that the left side of the face is generally perceived as more attractive than the right. This finding holds true regardless of whether the photograph is presented as originally taken or in a mirror-reversed image. Research corroborates this by measuring pupil dilation in participants viewing facial images, indicating a stronger positive response to left-sided portraits. [^1, ^2, ^3, ^4, ^5]
While the exact reason remains a subject of ongoing research, several theories exist. One prominent theory suggests the left side of the face shows more emotion because the right hemisphere of the brain (which controls the left side of the face) is associated with emotional expression. [^6, ^7] Another theory links this preference to the brain's inherent asymmetry: the right hemisphere's dominance in emotional processing might lead to more expressive and thus, more appealing, left-sided facial displays. [^8]
Implications and Considerations
It's important to note that individual variations exist. While the left side tends to be statistically more attractive, this doesn't apply universally to every individual. Facial attractiveness is complex, involving symmetry, unique features, and overall harmony. [^9, ^10] A person's perception of their own attractiveness can also differ from how others perceive them, particularly when comparing frontal and profile views. [^11, ^12]
Summary
The overwhelming evidence from multiple studies indicates a preference for the left side of the face. This preference is consistent regardless of image orientation and is likely linked to the brain's control over facial expressions.

[^5]: Photos showing the left sides of faces were rated more "pleasant" than those showing right sides--no matter whether the portraits were shown as taken originally or in mirror-reversed form. The researchers corroborated that finding by gauging the pupil size of the study participants' eyes. 22-Apr-2012 (Source provided in prompt)
