Fixing a Broken Face in a Generated Image

Faces break more visibly than anything else in a picture because people read them with far more precision than they read a hand or a bookshelf. A tree with an odd branch passes; an eye a few pixels off its axis does not. The good news is that a broken face on an otherwise good image is a local repair, and regenerating the whole picture is almost always the wrong response.

Small Faces Break, Large Faces Do Not

The single biggest predictor of a ruined face is how many pixels it occupies. A face that takes up a fifth of the frame comes out clean; a face at the far end of a room comes out as a smear with eye-shaped suggestions in it. This is not a prompt problem and no wording fixes it, because there simply is not enough resolution for the structure to form.

Which means the first thing to check when faces keep failing is framing. If the shot is a full-body figure in a wide landscape, either accept that the face will be small and unreadable — which is often fine and how real photographs behave — or move the camera in. Asking for a “detailed beautiful face” in a wide shot changes nothing.

Repaint the Region, Not the Picture

For a face that is large enough but wrong, mask the face and a margin around it, then describe the face as if writing it fresh: age, build, expression, the direction of gaze, the light falling on it. Keep the lighting words identical to the rest of the image or the repaired face will arrive lit from somewhere else, which is worse than the original defect.

Work in passes rather than trying to fix everything at once. Eyes are the usual culprit and often the only real problem — mismatched gaze direction, two different eye colours, pupils at different heights. Repair those alone, look again, and frequently the rest of the face was fine all along. Teeth are the second offender and are best handled by asking for a closed or slight smile rather than by trying to render a correct set of teeth at small scale.

Waxy Skin and the Repaired Look

The characteristic failure of a face repair is skin that looks polished — even, poreless, slightly plastic, noticeably smoother than the neck and hands it sits above. It happens because the repair pass tends to produce cleaner output than the surrounding image.

Counter it in the wording: skin texture, pores, fine lines, uneven skin tone, and avoid every word that pushes toward perfection. If the repaired face still reads as too clean against the rest of the picture, a second very light pass over the face and neck together, asking for consistent skin and matching grain, usually pulls it back into the image.

The last check is the one people skip. Look at the result at normal viewing size and at a distance. A face can be anatomically correct up close and still read as wrong because the head sits at an angle the neck does not support — and that is a body problem wearing a face problem’s clothes.
