Sunken eyes and low cheekbones: a midface plan

Quick facts
- Concern
- Sunken eyes with a marked under-eye hollow and a flat or dropped cheekbone
- Key question
- Does the hollow exist because the midface lacks support, and does treating the cheekbone change how the eye reads?
- Plan risk
- Treating only the tear trough, without support, and stacking product in a high-risk area
- First step
- Frontal and three-quarter photos with side lighting, assessing cheekbone projection and tear trough depth
Sunken eyes and low cheekbones are a classic pair in facial aging. The patient comes in complaining about the under-eye hollow, but what weighs most is the foundation: the apple of the cheek lost projection, the fat descended, the tear trough deepened and the shadow settled in. Treating only the tear trough, in that case, means treating the symptom in the riskiest area.
This page shows the relationship between the under-eye area and the cheekbone, the logic of planning the midface as a whole and the importance of starting with support. For the areas, see cheekbone and tear trough.
Why do the two concerns go together?
The midface is a support structure. The zygomatic bone, the fat compartments and the ligaments hold up the cheek and the lower eyelid. Over time, bone resorbs, deep fat loses volume and descends, and the ligaments anchor the skin at fixed points, creating grooves.
| Structure | Change | Visible effect |
|---|---|---|
| SOOF (suborbicularis oculi fat) | Volume loss and descent | Deeper tear trough and lid-cheek groove |
| Deep medial cheek fat | Descent | Cheekbone loses projection, nasolabial fold increases |
| Zygomatic bone | Resorption | Loss of cheekbone projection and a larger orbital space |
| Zygomatic ligament | Retention | Marked midcheek groove |
Result: the eye looks sunken because the base that supports it has dropped. See the general logic in fat compartments of the face and retaining ligaments and laxity.
Why start with the cheekbone
When cheekbone projection is insufficient, filling the tear trough creates a volume "hanging" over a missing base. The result tends to be swelling, a heavy look and the need for touch-ups. Supporting the midface, on the other hand, reduces the step and often lowers the amount of product the tear trough would need.
The tear trough is one of the highest vascular risk areas of the face. Reducing the volume needed there is, in itself, a safety strategy. That is why many plans follow the order cheekbone, then temple when indicated, and only then tear trough, if residual shadow remains. See cheekbone and tear trough: combining in the plan, full midface in the plan and flat cheekbone.
When bone is the main factor
In some patients, bone resorption of the zygoma and the orbit is the dominant factor. In these cases, soft tissue volume has a limited effect, and expectations need to be calibrated. A face with wide orbits and a flat cheekbone can improve the transition, but will not have the contour of someone with a projected skeleton. See when bone is the problem, not volume and facial skeleton before injecting.
Also consider age and the pace of change: a young person with an under-eye hollow and a flat cheekbone is a structural case from birth, while a 50-year-old with progressive change involves aging.
Step-by-step assessment
How to organize the plan
- Define the role of the cheekbone and the tear trough in the concern, with the lift test.
- Start with cheekbone projection, at a conservative volume.
- Reassess at 2 to 4 weeks, with standardized photos.
- Treat the tear trough only if relevant shadow persists.
- Consider the temples and the nasolabial fold to complete the midface.
The sequence lets you understand what each step did. See natural-effect plan and full midface in the plan.
Common mistakes
The first mistake is treating the tear trough in isolation, because that is what the patient points to. The visible concern is rarely the cause. The second is applying too much volume to the cheekbone in the first session, which rounds the face and creates an artificial expression. The third is not photographing with side lighting, which is precisely the light that shows the tear trough and the cheekbone projection; with front lighting, everything looks flatter and decisions turn out worse. The fourth is forgetting the nasolabial fold and the temple, which are part of the same midface and may call for attention in later steps. In every case, the antidote is the same: few areas at a time, conservative volumes, standardized photos and reassessment before adding more.
Simulation and expectations
Harmy lets you mark Cheekbone and Tear Trough together and compare Subtle, Moderate and Pronounced. The image below shows the effect of volume in the cheekbone on the fictional person. The projection is 2D, starts from the frontal photo and does not show profile or movement. It helps the patient visualize the relationship between the cheekbone and the tear trough, always as an illustrative simulation.
Summary for the decision
Sunken eyes and low cheekbones are a midface concern. Assess the support, start with the cheekbone at a conservative volume, treat the tear trough only if it is still needed and remember the vascular risk of the area. When bone is the dominant factor, calibrate expectations. Everything at the discretion of the qualified professional, in line with the rules of their professional council in Brazil, without promising results.
Frequently asked questions
Does filling the cheekbone improve the under-eye hollow?
In many faces it does, because midface projection reduces the step between the eyelid and the cheek and softens the shadow. The decision depends on the assessment, at the professional's discretion.
Should I treat the cheekbone before the tear trough?
Generally yes, when the cheekbone has little projection. Supporting the midface often reduces the amount of product needed in the highest-risk area, the tear trough.
Why do sunken eyes and low cheekbones go together?
Because aging reduces bone and fat support in the midface at the same time. The cheekbone descends and the tear trough deepens, and the two changes reinforce each other.
Does the simulation show both at once?
Harmy lets you mark Cheekbone and Tear Trough together and compare intensities in 2D, as an illustration, from the frontal photo.
