Why do small facial asymmetries look more obvious in photos than in person?

Small facial asymmetries often stand out more in photos for a few reasons.

First, a photo turns a 3D face into a 2D image. In real life, depth, motion, and changing viewing angles make tiny differences less noticeable. In a flat photo, features are fixed inside a rectangular frame, so viewers compare eye lines, mouth angle, and other features more directly.

Second, many people are most used to seeing themselves in a mirror, not in a normal photograph. A photo usually shows the non-mirrored version of your face—the way other people see you. Because your brain is familiar with your mirrored face, the photo can make normal asymmetries feel stronger or "wrong," even if others don’t notice anything unusual.

Third, pose, tilt, and perspective can exaggerate asymmetry. If your head is turned, tilted, or photographed from slightly above/below, the apparent difference between features can increase.

So the effect is usually a mix of 2D flattening, unfamiliarity with the non-mirrored view, and perspective/pose—not that your face is dramatically more asymmetrical in photos.
