Does everyone have an asymmetric face?

Everyone is a little asymmetric. Facial symmetry describes how closely the sides match; it doesn't require them to be identical.

Can a selfie measure facial symmetry?

Yes. It can compare left-right landmark distances mirrored across the midline. The result describes the image you supplied, so don't treat it as a permanent verdict.

Should I try to get a perfect symmetry score?

A perfect score isn't a useful requirement for your face. Symmetry has a small effect on rated attractiveness, and the measurement doesn't tell you that a feature needs changing.

What a facial symmetry measurement compares

A facial landmark is a point used to mark a feature's position in an image. A symmetry measurement compares corresponding points on opposite sides of the midline. The question is how closely those positions match when you mirror them.

This describes left-right facial balance. It doesn't describe every part of your appearance, and a small mismatch doesn't mean something needs fixing.

What the established evidence supports

Symmetry has a small effect on rated attractiveness. That supports a link, but it doesn't make symmetry a complete beauty score.

Perrett and colleagues examine that link in Symmetry and human facial attractiveness. Rhodes discusses the wider evidence in The evolutionary psychology of facial beauty.

Keep the size of the claim in view. A measurable difference between your facial halves doesn't establish how attractive someone will find you.

What the free scan measures

The free face-symmetry scan reads landmark distances from one selfie and reports left-right differences and basic ratios. It names what it measured.

Start with those labels. A named distance tells you what the result describes; an unexplained score leaves that unclear. If you compare photos, keep your pose and framing consistent so the comparison is easier to interpret.

How to use the result

Use the result to understand the measurements in that photo. Don't turn it into a target that every feature must meet.

Facial harmony concerns how features fit together, which is a broader question than whether both sides match. Canthal tilt and the golden ratio face describe different aspects of face geometry.

The glossary explains those terms separately. Check which feature a measurement describes before comparing it with another result.
