Facial Symmetry

How closely the left and right halves of your face match — measured without assuming where the midline is.

What asymmetry looks like to an observer

Facial symmetry compares paired features across the face. Perfect symmetry does not occur naturally and is not the practical target; what the metric detects is the degree of mismatch, which observers register as a general impression well before they can identify which specific feature differs.

Why MogTracker never builds a midline

This is the most technically involved metric in the set, and the method matters. Most naive implementations pick a midline and measure each side against it, which fails because any error in placing the midline is applied to every paired feature at once. MogTracker instead compares distances between paired landmarks directly, never constructing a midline. It also uses horizontal distances only — vertical comparisons cannot distinguish genuine asymmetry from ordinary head roll — and applies a noise floor so that sub-pixel landmark jitter is not reported as real asymmetry.

Why your score beats what the mirror suggests

Eye height is deliberately excluded, because blinks and expression swamp any genuine left-right difference. Six per cent of the composite depends on it. Small asymmetries are universal; only substantial ones move the score, which is why most users see a high number here even when they can identify differences in the mirror.

How to improve your facial symmetry

Facial symmetry compares left-right balance across eyes, cheekbones, jaw, nostrils, and mouth corners. Higher symmetry is universally associated with attractiveness.

Recommendations are grouped by how invasive they are. Non-invasive options change how the feature reads to an observer; surgical options change the underlying structure and therefore the measurement itself.
