Temple filler is one of the most useful and most underused treatments in facial rejuvenation. Volume loss in the temporal fossa shows up early, it skeletonises the lateral orbit and the upper third of the face, and it can make the mid-face look heavier than it really is. Restoring that concavity usually means a deep, supraperiosteal bolus with a firm, cohesive hyaluronic acid (HA) gel, or a blunt cannula in a more superficial plane. Both approaches work. Both demand a proper grasp of the anatomy, because the temple holds some of the most significant vessels in the face.
The temples sit in the transition zone between the forehead, the brow and the lateral cheek. As the temporal fat pads atrophy and the temporalis thins, the lateral brow loses support and the bony margins of the orbit and the zygomatic arch become more visible. Patients rarely say "my temples are hollow". They tend to say they look tired or gaunt.
For that reason, temple dermal filler is often best positioned as part of a full-face plan rather than a standalone request. Treating the temple first can soften the lateral orbital rim, give the tail of the brow a little more support and make subsequent cheek work look more balanced.
Temple filler for hooded eyes comes up in consultation often. Supporting the lateral brow can make a modest difference to lateral hooding in some patients, but it is not a brow lift. Be careful not to promise an eye-opening result, and document the conversation.
The temple is a layered structure, and each layer has its own risks. Working from superficial to deep:
A clear UK summary of these layers and their vessels appears in Helena Collier's temple restoration feature in The PMFA Journal. She notes the potential for significant anatomical variation in the pathway of the temporal vessels, and her conclusion is worth repeating to every trainee: there is no safe area and no safe depth, only safer practice.
Palpate and, where possible, visualise the superficial temporal artery before marking. It usually runs upwards from just in front of the tragus and branches into frontal and parietal divisions. Its frontal branch crosses the temple and connects with the supraorbital and supratrochlear systems, which is why intravascular injection here can, in rare cases, threaten vision. The middle temporal vein drains towards the cavernous sinus and has been linked to non-thrombotic embolic events, so you need to respect it in the deeper fascial planes.
There are two well-established approaches. Many experienced injectors use both, depending on the degree of hollowing, the patient's skin thickness and the product.
The most widely taught deep technique is the "one up, one over" approach credited to Dr Arthur Swift. From the junction of the temporal crest and the lateral orbital rim, the entry point sits roughly one finger-breadth up and one finger-breadth over. The needle is placed perpendicular to the skin, straight down to bone. You aspirate, then deposit a small, slow bolus on the periosteum while a finger guards the hairline and orbital rim.
Placement matters. In a cadaver study presented at the American Society of Plastic Surgeons meeting, CT imaging of HA placed with this technique showed the gel tracking inferiorly into the deep and infratemporal spaces behind the zygomatic arch. The authors concluded that volumes above about 0.5 ml at that point may not change the surface contour any further. They also found that injecting at least 0.5 cm more cephalo-posteriorly gave more localised volume. The practical lesson: if a large deep bolus is not lifting the hollow, adding more product to the same point is unlikely to help. Reassess the entry point instead.
The PMFA feature describes a similar superior-temple supraperiosteal approach, with a conservative first-session volume of no more than 0.5 ml per side. That fits a staged plan, with a review before you add more.
Cannula technique fans product through the loose areolar plane or the subcutaneous layer. It suits patients with mild-to-moderate hollowing, irregular contours or a hollow that extends towards the hairline. The entry point is usually near the hairline or the lateral brow tail. A 25G or 27G cannula is commonly used in the region. A blunt tip lowers the likelihood of piercing a vessel, but it does not remove the risk of intravascular injection.
For a broader view of gauge, length and tip design, see our guide to choosing a cannula for dermal filler, or browse the Filler World cannula range.
Deep supraperiosteal work generally calls for a cohesive, volumising HA with good lift capacity, for example the volume-category gels from the major ranges. Superficial cannula work suits a softer, more spreadable gel that integrates without visible lumps under thin temporal skin. Whatever you choose, check that the temple, or deep volumisation of the upper face, is covered in that product's IFU, and record batch and lot numbers in the patient notes.
Products that practitioners commonly consider include Belotero Volume with Lidocaine, which the PMFA author names as her preferred gel for the region. The full dermal filler collection lets you compare volumising options from other manufacturers.
Collagen stimulators such as poly-L-lactic acid and calcium hydroxylapatite are also used in the temple, particularly where you want gradual, diffuse correction. They cannot be dissolved, so they need more training and careful patient selection. Our PLLA filler guide covers reconstitution and placement in more detail.
Patients increasingly search for "temple filler gone wrong" before they book, so your consent process needs to be thorough.
This is the complication that matters most. Signs include immediate blanching, disproportionate pain, livedo or mottling spreading along a vascular territory, and, in the most serious cases, visual disturbance, ptosis or ophthalmoplegia. Any visual symptom is an emergency that needs immediate escalation to ophthalmology or emergency services, without waiting to see whether it settles. Every clinic offering temple work should have a written vascular occlusion protocol, an in-date emergency kit containing hyaluronidase obtained through an appropriate prescriber, and staff who have rehearsed the protocol. Follow a recognised UK consensus guideline, such as those published by the Aesthetic Complications Expert Group, and keep your training current.
Temple filler migration usually comes from placing too much product in one plane, from a gel that is too soft for deep work, or from the inferior tracking described above. Palpable lumps are more common with superficial placement under thin skin. Staged treatment and conservative volumes reduce both problems.
Discuss bruising, swelling, tenderness when chewing (from deep injection near the temporalis), headache, transient asymmetry and the small risk of infection or delayed inflammatory reactions. Record the discussion, the products used, the volumes, the planes and the entry points.
No single product is best for every temple. For a deep supraperiosteal bolus, most practitioners choose a cohesive, volumising HA. For superficial cannula work, a softer, more spreadable gel is usually preferred. Check that the IFU covers the indication, and match the product to the plane and the skin thickness.
The temple contains the superficial temporal artery, the middle temporal vein and the deep temporal arteries, so intravascular injection is a real risk. Detailed anatomical knowledge, careful marking, slow low-pressure injection, conservative volumes and a rehearsed complications protocol all reduce that risk, but none of them remove it.
Both are established. A needle to bone suits a deep, focal bolus in moderate-to-severe hollowing. A blunt cannula suits superficial, diffuse correction and contour irregularities. Choose based on the anatomy, the product and your training, not on habit.
Requirements vary widely. Many practitioners start with up to 0.5 ml per side and review before adding more, because cadaver imaging suggests larger single deep boluses may track inferiorly without improving the surface contour.
Duration depends on the product, the plane, the volume and the patient, so quote the range given in the product's own IFU rather than a figure of your own.
Done well, temple filler can rebalance the upper face and make the rest of a treatment plan look more natural. Done carelessly, it is one of the riskier areas in aesthetic injecting. Know the layers, map the vessels, choose a product that suits the plane, stage your volumes and have a complications protocol you have actually practised.
