Zygomatic bones
The zygomatic bones are the paired cheekbones, forming the outer rim of the eye socket and the arch running back towards the ear. How prominent they look in a photo is mostly the fat over them and the direction of the light, not the bone. The bone is structural and reported as a band; fat and lighting are what move.
Also called: cheekbones, zygos, malars, zygomatic arch
What are the zygomatic bones?
Each zygomatic bone sits below and to the side of the eye. It forms the lower outer rim of the orbit, joins the maxilla towards the nose, and sends an arch backwards to the temporal bone by the ear. That arch is the widest point of most faces and is where the width in fWHR comes from. Forums call them zygos or malars and treat them as the mark of a striking face.
"High cheekbones" means the body of the bone, the part you can feel under the outer corner of the eye, sits high and stands forward, so the cheek below it falls away into a hollow. "Flat" cheekbones sit lower or do not project, and the cheek reads as one plane. The difference between people is real but small, and in a photo it is almost always outweighed by what lies on top of the bone.
What a photo can and cannot show
A frontal photo shows a highlight where the cheek catches light and a shadow where it turns away. It cannot see the bone. What it sees is the surface of the fat pads over the bone, lit from wherever the light happens to be, which is why the model reads cheek prominence as a directional band with a capture grade beside it. Two things dominate the photo:
- Fat. The malar fat pad sits directly over the zygomatic body, and the buccal fat below it fills the hollow that would otherwise show the bone's lower edge. At higher body fat both are fuller and the face reads as one smooth curve; leaner, the bone comes through.
- Light. Light from above and slightly in front puts a highlight on top of the cheekbone and a shadow beneath it, which is why portrait photographers use it. Flat frontal light from a phone screen or a ring light erases the same bone.
Are zygomatic bones workable or structural?
The bone is structural. Its height, width and projection are set by the skull and do not change with any routine; BecomeTen tags it structural and reports it as a band. Overlying fat is the whole of the workable margin: the same skull at a lower body fat reads as more prominent cheekbones because the malar and buccal pads hiding the edge are smaller. The harmony cap is +6 partly because that fat lever is shared with the jaw and counted there.
What actually changes how zygomatic bones read?
- Body fat. The only lever that changes the band. Lower body fat thins the malar and buccal pads and the bone's edge shows. See body fat percentage and facial definition.
- Lighting from above. The same bone reads flat under a ring light and sculpted under a window. Match the light between scans or the change is the lamp.
- Smiling. A smile lifts the malar pad up over the bone and rounds the whole cheek. Neutral expression for the photo.
- Age-related fat loss. Over decades the malar pad descends and thins, so cheekbones often read higher in the forties than the twenties while the hollow beneath deepens. The bone has not moved.

Questions
Do my zygomatic bones look bigger when I lose weight?
They look more prominent, which is not the same thing. The bone stays exactly as it was; the malar and buccal fat pads over and below it shrink, so the edge shows through and the hollow beneath appears. Perception research finds observers read that change reliably, which is why body fat is the one lever that moves the cheek band.
Why do my zygomatic bones show in some photos and vanish in others?
Lighting. Light from above and slightly in front puts a highlight on top of the cheekbone and a shadow under it; flat light from a phone screen, a ring light or an overcast window facing you removes both. The bone is identical in every frame. Match the light between scans, or the report is comparing lamps.
Does BecomeTen ever suggest cheek filler for flat zygomatic bones?
No, at any tier. Filler, fat grafting and implants are procedures, and BecomeTen does not recommend procedures from a photo or point you to a clinic. The report tags the bone structural, reports it as a band, and puts the workable margin where it belongs: overlying fat, lighting and expression.
