What Gets Measured
MogScore detects 468 facial landmarks using MediaPipe, then compares 7 paired points to calculate your symmetry score:
Outer eye corners
Left vs right palpebral fissure positioning
Inner eye corners
Medial canthus alignment with nasal bridge
Eyebrow inner points
Brow origin symmetry near glabella
Eyebrow mid points
Brow arch height and position
Nostrils
Alar base width balance left vs right
Mouth corners
Oral commissure horizontal alignment
Jaw angles (gonion)
Mandibular angle symmetry — affects face taper
Why Symmetry Matters Most
Research consistently shows facial symmetry is the strongest predictor of perceived attractiveness across cultures. Humans detect asymmetry subconsciously in approximately 100 milliseconds.
In MogScore's scoring system, symmetry carries the highest weight of any single metric: 16% for men and 14% for women. This is because asymmetry affects the perception of every other feature — even a great jawline looks worse on an asymmetrical face.
How to Improve Facial Symmetry
Chewing habits. Alternate sides when chewing to develop masseter muscles evenly. Unilateral chewing is one of the most common causes of jaw asymmetry.
Sleep position. Consistently sleeping on one side can compress facial soft tissue over time. Try alternating or sleeping on your back.
Body fat. Lower body fat reveals more of your bone structure and can make existing symmetry more visible.
Grooming. Strategic brow shaping, facial hair, and hairstyle can create the illusion of better symmetry.
Frequently Asked Questions
How is facial symmetry measured?
MogScore measures symmetry across 7 paired landmarks: outer eye corners, inner eye corners, eyebrow inner points, eyebrow mid points, nostrils, mouth corners, and jaw angles (gonion). Each pair is compared for distance from the facial midline.
Is perfect facial symmetry possible?
No face is perfectly symmetrical. Even the most attractive faces have 2-3% asymmetry. A score of 8+ indicates excellent symmetry that most people would perceive as 'perfectly balanced.'
Can I improve my facial symmetry?
Some factors affecting symmetry are controllable: chewing habits, sleep position, posture, and body fat percentage. Bone structure asymmetry is largely fixed but can be minimized through grooming strategies.
