Why temples hollow with age
The temple is one of the first areas of the face to lose volume, and one of the last that patients notice. Three tissues thin at once. The superficial and deep temporal fat pads shrink from the late twenties onwards, the temporalis muscle loses bulk with age and with reduced chewing load, and the bone of the temporal fossa itself remodels. The result is a gradual scalloping between the brow bone and the hairline.
Because the change is slow and symmetrical, most patients do not identify the temple as the problem. They report looking tired, gaunt or older without being able to say why, or they notice secondary effects: the tail of the brow drops as its lateral support recedes, the upper face narrows into a "peanut" shape, and the bony rim of the eye socket becomes more visible.
Weight loss accelerates all of this, which is why marked temple hollowing is increasingly seen in younger patients after rapid weight reduction, including patients using GLP-1 medication. Endurance athletes and patients with naturally low body fat show it earliest.
What hollow temples do to a face
The youthful face is often described as an inverted triangle, wide at the cheekbones and temples, tapering to the chin. Temple hollowing inverts part of that geometry. The face reads as narrower at the top, the cheekbones appear to jut rather than blend, and the lateral brow loses its gentle upward sweep.
This is why temple filler is fundamentally a balancing treatment rather than a spot correction. Injectors who assess the face as a whole frequently treat temples in patients who arrived asking about their cheeks or eyes, because restoring the frame changes how everything inside it is read. Conversely, filling cheeks in a patient with empty temples can make the mid face look heavy and the upper face even more skeletal.
Temple filler rarely produces a change anyone can name. Done well, people say you look rested. Done badly, the temple is one of the least forgiving areas on the face.
Product choice
Two broad product families are used in the temple, and they behave differently.
| Product type | Behaviour | Reversible | Typical duration |
|---|---|---|---|
| High-G-prime hyaluronic acid | Structural support, immediate result | Yes, with hyaluronidase | 9 to 18 months |
| Softer hyaluronic acid | Subtle blending in thin-skinned patients | Yes | 6 to 12 months |
| Biostimulators (calcium hydroxylapatite, poly-L-lactic acid) | Gradual collagen response over months | No, or only partially | 18 months or more |
For a first treatment there is a strong argument for hyaluronic acid, simply because it can be dissolved. The temple sits directly beside the eye's vascular supply, and reversibility is not a cosmetic nicety here, it is a safety feature. Our separate guide to how hyaluronidase dissolving works explains what reversal actually involves.
Volume requirements surprise patients. The temporal fossa is a genuine three-dimensional space, and meaningful correction commonly requires 0.5ml to 1ml per side, sometimes staged over two sessions. Anyone promising full correction of deep hollows with a fraction of that is managing a budget, not an outcome.
Technique, and why the anatomy dictates it
The temple is anatomically unusual: it is layered like a lasagne, with the superficial temporal artery, the middle temporal vein, the deep temporal arteries and branches of the facial nerve each running in different planes. Injectors therefore work in one of two relatively safe planes and avoid everything between.
- Deep, on bone. A needle is passed vertically down to the periosteum, classically about one centimetre up from the zygomatic arch and one centimetre back from the orbital rim, and product is deposited beneath the temporalis. This plane sits below the major named vessels, though the deep temporal arteries still run nearby.
- Superficial, by cannula. A blunt cannula is threaded in the subcutaneous or interfascial plane from a distant entry point, laying soft product in thin layers. This avoids repeated needle passes but demands precise depth control, because the middle temporal vein runs in this territory.
Neither plane is risk-free, and the choice depends on the patient's anatomy, the product selected and the injector's training. What should concern a patient is an injector who cannot explain which plane they use and why. In the temple, that explanation is the consultation.
Risks in the temple specifically
Common and self-limiting effects include bruising, tenderness, temporary headache and a feeling of tightness when chewing, since the temporalis is a chewing muscle. Visible product or surface irregularity can occur with superficial placement in thin-skinned patients.
The serious risk is vascular. The temple's arterial network connects, through the orbital vessels, with the blood supply to the eye. Filler injected into a vessel here can, rarely, embolise and cause skin necrosis or visual loss. Published estimates of filler-related blindness across all facial areas number in the low hundreds of cases worldwide, which makes it very rare, but the temple, glabella and nose account for a disproportionate share.
That risk is managed, not eliminated, by anatomical technique, slow low-pressure injection, reversible product, and a practitioner equipped to recognise and treat a vascular event immediately, which means hyaluronidase in the room, not on order. The regulatory backdrop matters here too: dermal fillers remain only lightly regulated in the UK, a gap explained in our piece on what "aesthetic clinic" actually means in UK law, so the burden of verification sits with the patient. Checking a practitioner against the GMC register or an accreditation scheme such as Save Face takes minutes.
Results, longevity and cost
Results with hyaluronic acid are immediate, with mild swelling settling over one to two weeks. Biostimulators build gradually over two to three months and suit patients wanting a slower, less announced change. Observed UK pricing in 2026 runs from roughly £300 to £650 per session depending on product and volume, with staged treatments costing more in total. Wider market context sits in our 2026 UK price survey.
Deep hollows are usually corrected over two visits rather than one. Restraint per session is not upselling; overfilled temples look convex and unnatural, and correcting that is harder than adding more later.
Choosing a practitioner
The temple is a poor place to learn on. Reasonable screening questions: are you a registered healthcare professional, which plane do you inject and why, do you hold hyaluronidase on site, and how many temple treatments have you personally performed. A confident, specific answer to all four is the minimum.
Medical oversight is the operative phrase. In west London, practices such as Dr Harry Clinic in Chiswick perform temple filler under doctor-led protocols, which is the model this publication considers appropriate for the area: prescriber on site, emergency medication stocked, and a consultation that includes the option of not treating. Wherever you are in the UK, that is the standard to look for, and any clinic meeting it will be unbothered by the questions above.
