What changes here?
Genetics, ageing, weight loss, soft-tissue deflation, skeletal contour, muscle anatomy and previous filler or surgery can make the temples appear hollow, narrow, asymmetric or disproportionately full.
Body Area / Face
The temples form the transition between forehead, brow, lateral orbit and cheek. Their contour depends on temporal bone, temporalis muscle, fat compartments, fascia and the surrounding upper-face proportions.
Anatomical lens
Genetics, ageing, weight loss, soft-tissue deflation, skeletal contour, muscle anatomy and previous filler or surgery can make the temples appear hollow, narrow, asymmetric or disproportionately full.
Temporal hollowing, a skeletal or sunken appearance, upper-face narrowing, asymmetry, visible vessels, excessive fullness after filler and imbalance between the forehead, brow and cheek.
Temporal contour from front and oblique views, skeletal width, temporalis muscle, superficial and deep volume, brow and forehead relationship, cheek projection, vascular anatomy, asymmetry, previous filler or fat grafting and whether volume restoration would actually improve the whole face.
The temples are relatively quiet anatomical regions until they lose volume. Then the change can affect much more than the small depression beside the forehead. Temporal hollowing can make the upper face look narrower, make the brow and lateral orbital rim appear more skeletal and increase the visual prominence of the cheekbone. Restoring that region can therefore alter the apparent proportions of several neighbouring structures at once.
But the temple is not simply an empty space waiting to be filled. Beneath the skin lie fascia, superficial vessels, deeper fat, the temporalis muscle and the temporal bone. Important vascular pathways pass through and around the region. The fact that the external surface looks concave does not mean there is one universal safe layer into which arbitrary volume can be added.
I therefore approach the temple as a structural transition rather than a filler site. The first question is whether the hollow is genuinely disproportionate, what layer is producing it and whether correcting it improves the forehead–brow–cheek relationship or simply makes the upper face wider.
The frontal bone and lateral orbital rim transition toward the temporal fossa, where the skull naturally becomes more concave. Some degree of temporal depression is therefore normal anatomy. The upper face is not meant to form one continuously convex plane from forehead to cheek.
Individual skeletal shape creates substantial variation. One patient can have naturally broad temporal bones and relatively little visible concavity from youth. Another can have a naturally narrow upper face with deeper temples despite having healthy soft-tissue volume. This difference does not automatically represent ageing or deficiency.
I want to know what changed. A temple that has gradually hollowed over time tells a different story from a temple that has looked concave since adolescence. Restoration is more coherent when it replaces a meaningful loss than when it is used simply to convert one normal facial frame into another.
A hollow temple is not treated because concavity exists. It is treated when that concavity has become disproportionate to the face around it.
Temporal ageing can involve loss and redistribution of soft tissue, changes in skin and deeper skeletal remodelling. As volume decreases, the temporal line can become more obvious, vessels may become easier to see and the transition into the lateral forehead can look sharper.
These changes can make the upper face appear more skeletal even when the central forehead and cheek retain reasonable volume. The hollow can therefore contribute to a tired or aged appearance without creating a conventional wrinkle.
That does not mean every age-related temporal change needs to be filled. Some degree of contour is natural and often aesthetically useful. The objective is to restore a lost transition, not to create an inflated lateral forehead.
Substantial weight reduction can reduce facial soft-tissue volume as well as body fat. In some patients the temples become noticeably more concave and the cheekbones appear more prominent. The face can look leaner than intended even when the weight change itself was healthy.
The timing matters. If weight is still changing, facial volume is still changing as well. Restoring volume during an active loss phase can lead to an overfilled result once the patient’s body composition stabilises or, conversely, may require repeated correction as more volume is lost.
I prefer to treat a reasonably stable face. A temple should not become a moving target in which filler is repeatedly added to chase ongoing systemic change.
The temporalis is a broad chewing muscle occupying much of the temporal fossa. Its thickness and shape vary among individuals, and the contour changes when the jaw is clenched. A patient with relatively thin temporalis anatomy can appear more hollow even when superficial soft-tissue volume is normal.
This is useful during assessment because the external concavity is partly structural. Injecting increasingly large amounts superficially cannot convert the underlying muscle and bone into another anatomical frame. The treatment can soften the transition, but it should not attempt to erase every sign of the temporal fossa.
Movement also matters. A result that looks smooth at rest should remain natural when the patient chews and the muscle contracts underneath it.
The brow forms the superior medial neighbour of the temple, while the lateral orbital rim sits between temple and eye. When temporal volume decreases, these structures can appear sharper and more exposed.
In selected patients, restoring temple volume can therefore make the brow–orbit transition look softer without changing the brow itself. But a low brow or true upper-eyelid problem does not become a temple-volume deficiency simply because the three regions are adjacent.
This is why upper-face assessment matters. A patient who feels skeletal around the eyes may have several components: temporal hollowing, upper-eyelid hollowing, brow position or loss of lateral cheek support. Filling only the temple can improve one transition while leaving the actual dominant problem untouched.
A prominent lateral cheekbone beneath a narrow temple creates a stronger inward curve between the forehead and midface. This can be genetically attractive and completely normal. In another patient, age-related temporal loss creates a contrast that feels newly severe.
The distinction matters because increasing temple volume changes facial width. If the cheek is already broad, overfilling the temple can turn the entire upper and midface into one continuous wide plane. The original hollow may disappear, but so does the natural change in contour between temporal fossa and zygoma.
I therefore want the temple to connect the forehead and cheek rather than compete with either of them.
The temple contains superficial and deep vascular structures, and facial arterial networks can communicate with vessels associated with the eye. Intravascular filler injection can cause tissue ischemia and, in rare catastrophic cases, visual loss. The low frequency of these events does not make the anatomy low risk.
This is why I do not think of temporal filler as a casual add-on performed simply because a syringe has product left after another facial treatment. Product selection, plane, entry point, injection method, volume and anatomical understanding all matter.
No needle or cannula automatically converts the temple into a safe zone. Technique can reduce risk; it cannot make vascular anatomy disappear.
The question is not whether filler can be placed in the temple. The question is whether the improvement is large enough to justify placing filler in a high-consequence anatomical region.
Volume can be restored at different anatomical depths depending on the patient’s structure and the material being used. Deeper placement can influence the underlying concavity differently from superficial correction of a visible contour transition. These are not merely interchangeable routes to the same result.
The amount required also changes according to plane and baseline anatomy. A modest deep correction can sometimes soften the entire fossa, while superficial overcorrection can make product visible or create an oedematous transition.
I do not think the patient needs to arrive knowing which plane should be used. That is part of technical planning. But they should understand that temporal treatment is anatomical reconstruction in layers rather than filling an empty bowl from the surface inward.
Hyaluronic-acid filler is attractive in many facial regions because volume can be adjusted and the material can be dissolved with hyaluronidase when appropriate. In the temple, this controllability can be useful.
But reversibility is not a safety licence. Vascular complications require immediate recognition and management, and visual complications can have consequences that are not made trivial by the existence of an enzyme capable of degrading HA.
I therefore choose filler because it fits the anatomical and treatment objective, not because the possibility of dissolution permits a lower treatment threshold.
Autologous fat can restore temporal volume in selected patients, particularly when broader facial fat grafting is already being considered. It can provide a soft transition and does not require a synthetic filler product.
The biological behaviour is different. Some transferred fat survives long term, while some is resorbed. Final retention varies, and the surviving tissue can change with future weight gain and loss.
Fat grafting also does not eliminate vascular risk simply because the material is autologous. Injection anatomy remains important, and the procedure should not be treated casually. “Natural material” describes origin, not automatic safety.
Temporal augmentation is usually intended to be subtle. With repeated treatment, however, residual product can accumulate or spread and the upper face can gradually become broader. Because this change occurs over several sessions, neither patient nor practitioner may notice exactly when restoration became augmentation.
The forehead-to-cheek transition can become convex rather than softly concave, and the temple may appear puffy or heavy. In HA-treated patients, reassessment can include whether residual material should be reduced rather than automatically adding the scheduled maintenance volume.
Maintenance should therefore follow the current face. The original hollow being treated years earlier is not proof that the temple remains deficient today.
Superficial vessels can become more apparent in thin skin and with loss of surrounding soft-tissue cover. Filling the region can sometimes make them visually less prominent, but the vessel itself is not an aesthetic defect simply because it can be seen.
Vascular prominence also changes with temperature, exercise and individual anatomy. If the principal concern is one specific superficial vessel rather than actual temporal hollowing, the treatment question may be different.
I prefer not to add substantial facial volume simply to camouflage normal vascular anatomy when the temporal contour itself is already proportionate.
One temporal hollow can be deeper because of skeletal asymmetry, differences in muscle volume, previous trauma or soft-tissue distribution. The brow and cheek may also differ on the same side, making the temple appear more asymmetric than it would in isolation.
Small volume differences can be corrected selectively. But attempting to make the two temples mathematically identical without considering the rest of the face can make one side disproportionately wide.
Symmetry should therefore be judged as part of the entire upper face. Equal millilitres and equal external curves are not necessarily the same thing.
The temporal hairline frames the lateral forehead. Recession can expose more of the temporal fossa and make the area appear more hollow even when soft-tissue volume has changed little. This is especially relevant in patients with frontotemporal hair loss.
In those patients, filler and hair restoration solve different components. Adding volume can soften the underlying contour, while hair transplantation can change how much of that contour is visible and alter the shape of the forehead.
The treatment should follow whichever mechanism is actually producing the concern. A wider visible temple created mainly by hair recession is not automatically evidence that more filler belongs underneath it.
I look at the face from the front and oblique views. Forehead width, temporal concavity, brow, lateral orbit and cheek are assessed as one transition. I want to know whether the temple became hollow over time, after weight loss or has always been shaped that way.
Previous HA filler, fat grafting, brow surgery and facial lifting are relevant because they can change both volume and tissue planes. I observe the region at rest and with jaw contraction to understand how temporalis anatomy contributes.
Then I ask whether restoration improves the face globally. A hollow that is visible close-up but gives the face useful contour from normal viewing distance may not need to be erased. The indication belongs to facial proportion rather than to the presence of concavity itself.
The temple is not a region where I want the patient to see newly created volume. The useful result is that the upper face no longer looks unexpectedly skeletal, the transition beside the brow becomes softer and neighbouring structures feel less isolated.
If the first thing the viewer notices is that the temples are full, the treatment has probably become too visible. Normal temporal anatomy retains some concavity.
I therefore prefer to stop before the region becomes completely flat or convex. Less volume often produces the more believable result because the goal is restoration of continuity rather than construction of a new feature.
Consultation is useful when temporal hollowing has become noticeably stronger with ageing or weight change, when one temple differs substantially from the other, or when previous filler has produced excessive fullness or irregularity.
It is also useful when a patient believes the upper face looks skeletal but cannot determine whether the problem comes from temples, brow, eyelids, cheek or hairline. Those structures can create similar visual impressions while requiring different treatment approaches.
Because the temple is vascularly consequential, I set a higher indication threshold than I would for a low-risk superficial cosmetic concern. If the hollow is mild and the expected improvement is small, doing nothing can be more appropriate than treating normal anatomy simply because it is technically possible.
Changes in soft-tissue volume, skeletal contour and surrounding facial structures can make the temporal fossa more visible over time. Weight loss can also increase the appearance in some patients.
No. Some people have naturally concave temples because of skeletal and muscular anatomy. Treatment is more coherent when the hollow is disproportionate or represents a meaningful change rather than simply normal baseline shape.
In an appropriately selected patient, restoring lost temporal volume can soften a skeletal upper-face appearance and improve the transition between forehead, brow and cheek. The expected effect should remain subtle.
The temple is a vascularly important region. Serious filler complications are rare but can include vascular occlusion and potentially visual injury. This is why anatomy, technique and a clear treatment indication are particularly important.
Neither instrument eliminates vascular risk. Their behaviour and the appropriate plane differ, and safety depends on anatomical knowledge and technique rather than on treating one device as universally safe.
Yes in selected patients, particularly when broader facial fat grafting is appropriate. Fat has different longevity and biological behaviour from HA filler and still requires careful injection anatomy.
Yes. Overcorrection can flatten the normal temporal concavity and create an excessively broad or puffy upper face. Maintenance should be based on current anatomy rather than automatic repeated volume.
Yes. Loss of temporal hair can expose more of the underlying temporal fossa and change the visible width and shape of the forehead even when soft-tissue volume itself has changed little.
I would avoid augmentation when the concavity is normal and proportionate, when the expected aesthetic gain is too small for the vascular risk, when previous product has already created adequate volume or when the apparent hollow is mainly being produced by another structure such as the hairline or cheek.
