Temple (temporal) hollowing is among the most overlooked yet visually impactful signs of facial aging. In Asian facial aesthetics, a full and rounded upper face has been associated with youth and auspicious facial harmony since ancient times — the temple region provides a rounded, flowing frame for the entire face. However, with aging or due to congenital factors, atrophy of the temporal fat pads and temporalis muscle volume, combined with resorption of the greater wing of the sphenoid bone, causes the temples to concave inward, producing a cascade of facial proportion distortions: (1) Cheekbones visually appear more prominent — they haven’t actually enlarged, but the surrounding framework has been hollowed out. (2) The lateral brow tail loses underlying support, subtly descending — adding to a tired, melancholy facial expression. (3) The frontal facial contour transforms from oval to diamond or pear-shaped. (4) The overall facial expression shifts from soft and rounded to gaunt and angular — in Asian aesthetic perception, this signals aging and severity. Rappoel Dermatology near Gangnam Station, Seoul, uses high-G’ large-particle hyaluronic acid fillers (Restylane Lyft / Juvederm Voluma level), precisely injected in the supraperiosteal plane to reconstruct the temple’s volumetric scaffold, restoring youthful upper-face fullness in a single session.
Why Do Temples Hollow? — The Multi-Mechanism of Temple Aging
- Superficial temporal fat pad atrophy: The temporal region contains two fat compartments — the superficial temporal fat pad and the deep temporal fat pad. The superficial pad lies on the surface of the superficial temporal fascia (immediately subdermal); it undergoes systemic age-related adipose atrophy and is the single largest contributor to temple hollowing (approximately 60-70%)
- Deep temporal fat pad degeneration: The deep temporal fat pad sits between the temporalis muscle and the sphenoid periosteum — this deep pad acts as a cushion between bone and soft tissue; its atrophy causes the temporalis muscle to directly appose bone, deepening the hollowed visual
- Temporalis muscle volume reduction: As bite force diminishes with age and dietary habit changes, the temporalis — a muscle of mastication — undergoes functional atrophy, further reducing temporal soft-tissue support
- Greater sphenoid wing bone resorption: Craniofacial bones undergo age-related resorption, and the greater wing of the sphenoid (the deepest bony foundation of the temple) is particularly susceptible — its resorption directly lowers the bony floor of the temple, causing overlying soft tissue to collapse even if fat and muscle volume remained unchanged
- Deep temporal fascia and retinacular laxity: The ligamentous system anchoring temporal soft tissue to the periosteum loosens with age, permitting further downward soft-tissue displacement — this represents the upstream connection between temple hollowing and mid-face descent
Rappoel Temple Filler Technical Essentials
- Supraperiosteal deep-plane injection — building the foundation, not piling sand: The key to successful temple filler lies in the injection plane — Rappoel selects the deep supraperiosteal plane (immediately above the bone). Filling in this plane builds a volumetric scaffold from the bottom up rather than creating a superficial mound — results appear more natural (no detectable filler contour), lift is more durable (less susceptible to degradation and migration), and volume efficiency is higher (greater effect per cc)
- High-G’ large-particle HA — engineered for lasting structural support: The temple must bear the lateral tensile forces of skin and galea aponeurotica — requiring high-G’ (elastic modulus, a measure of a filler’s resistance to deformation and shape maintenance) large-particle cross-linked HA — such as Restylane Lyft (G’ approximately 650Pa) or Juvederm Voluma (G’ approximately 330Pa), significantly higher than ordinary medium-molecular-weight HA (G’ approximately 50-150Pa), to provide sufficient mechanical support without being compressed or absorbed
- Ultrasound-guided precision injection: The superficial temporal artery and its branches (particularly the zygomatico-orbital artery) course through the temple — clearly visible on ultrasound — Rappoel uses ultrasound guidance to ensure the needle remains well away from all critical vessels, reducing the theoretical risk of intravascular injection to near zero
- Multi-angle, multi-point fanning technique: The temple is not a simple planar depression but a bowl-shaped three-dimensional volume loss — a single entry point and direction cannot uniformly reconstruct volume in all zones. Rappoel employs a multi-point fanning approach from two entry points (hairline and lateral brow) with three fanning-plane trajectories, ensuring uniform fullness throughout the temporal fossa from anterior to posterior and medial to lateral
- Bilateral symmetry real-time calibration: After temporal injection, the physician immediately asks the client to sit upright for frontal and bilateral mirror confirmation of symmetry — because in the supine position, temporal soft tissue shifts posteriorly under gravity, and supine state symmetry assessment does not necessarily reflect true standing-state symmetry
Rappoel Temple Filler Treatment Protocol
- Temporal assessment and plan design (15 min): Frontal and lateral evaluation of temporal fossa hollowing severity → digital palpation confirming temporalis muscle boundaries and superficial temporal artery pulsation → ultrasound confirmation of vascular trajectory → marking injection danger zones (vascular paths) and safe injection zones (supraperiosteal plane) → estimated 2-4ml per side
- Disinfection and anesthesia (10 min): Povidone-iodine preparation of temples and hairline → lidocaine-integrated HA filler provides intrinsic local anesthesia, no additional anesthetic injection required
- Ultrasound-guided HA filler injection (20-25 min): 25G/27G blunt cannula (optimal for vascular avoidance), entering via hairline and lateral brow → fanning injection in the supraperiosteal plane under real-time ultrasound imaging guidance → 2-4ml per side, slow and even injection (rapid delivery risks small vessel damage and uneven filling)
- Symmetry check and massage sculpting (10 min): Client sits upright for mirror confirmation → physician gently massages to achieve even filler distribution → immediate post-treatment photography
HA temple filler is one of Rappoel’s most discreetly transformative treatments — most people won’t consciously identify what you had done; they’ll simply notice you suddenly look fresher, your facial contour flows more harmoniously, and your expression appears softer.

Frequently Asked Questions
What’s the difference between HA temple filler and fat grafting to the temples?
Two mainstream material options exist for temple augmentation, each with distinct merits: (1) HA filler — advantages: immediately precise and controllable + reversible (if overfilled or dissatisfied, hyaluronidase can dissolve it); visible and palpable results right away; lasts 12-18 months. Ideal for first-time temple filling or those wanting a reversible option. (2) Autologous fat grafting — advantages: once survived, results are permanent; fat harvested from thighs or abdomen, purified, and transferred to the temples; approximately 50-70% survival rate means initial overcorrection of 20-30% is planned; final results are natural and enduring. Ideal for those with prior HA temple filler experience who have a clear vision of their desired contour and seek a long-term solution. (3) Rappoel’s recommendation: try HA filler first as a ‘fitting room’ (12-18 months); if you genuinely love and adapt to the fuller upper face, then opt for permanent fat grafting. HA filler lets you test-drive the look; fat grafting is the custom-tailored suit. Avoid committing to irreversible fat grafting upfront — if you dislike the shape or experience uneven absorption, there’s no going back.
Is there a risk of vascular occlusion with temple filler?
Theoretical vascular occlusion risk exists (as with any injectable filler), but under Rappoel’s protocol, the risk is minimized to near zero through three layers of protection: (1) Injection plane precisely at the supraperiosteal level — the superficial temporal artery trunk and zygomatico-orbital artery course through the superficial temporal fascia (a superficial plane >1cm above the skin surface), whereas the supraperiosteal plane as the injection layer is separated by a natural anatomical barrier (the deep temporal fascia); the blunt cannula’s deep-to-superficial trajectory further reduces vessel penetration probability. (2) Real-time ultrasound guidance — pre-injection color Doppler ultrasound clearly displays the exact location and depth of the superficial temporal artery and its branches; the injection path actively avoids them in real time — this is impossible with naked-eye or palpation guidance alone. (3) Blunt cannula + slow fanning injection — a cannula is far less likely to penetrate vessel walls than a sharp needle. Conclusion: under experienced physician + ultrasound guidance + blunt cannula technique, the risk of temple vascular occlusion approaches zero.
What’s the recovery period for temple filler? How much swelling?
The temple region produces substantially less swelling than lips or tear troughs — because temporal tissue tension is low and lymphatic drainage is excellent. Recovery timeline: 1-2 hours post-treatment — mild redness and swelling (localized needle-trauma response), concealable with hair. Day 1 — mild swelling; the temple appears approximately 10-15% fuller than the final result (false volume from edema); doesn’t prevent going out (hair and bangs can disguise). Day 3 — swelling substantially resolved; the true filler contour begins emerging; feels like normal soft tissue to touch. Days 5-7 — appearance fully stabilized; HA-water equilibrium achieved and final contour established. 1 month — HA fully tissue-integrated; appearance and texture completely natural. Temple filler’s greatest advantage: unlike lips, it doesn’t draw attention through swelling — the temple is inherently a low-visibility zone; mild post-treatment swelling is indistinguishable from normal daily water retention or fatigue.
How much filler is needed per temple?
Significant individual variation; typical reference ranges: Mild hollowing (cheekbone slightly prominent laterally, temple mildly concave but not aging in appearance) — 1-1.5ml per side. Moderate hollowing (temple visibly concave inward, lateral profile presents a flat plane rather than an arc, cheekbone noticeably prominent) — 2-2.5ml per side. Severe hollowing (deep temple concavity forming a continuous orbito-temporal depression, facial contour fully diamond-shaped) — 3-4ml per side. Rappoel’s strategy: conservative initial fill with 4-week touch-up option — first session targets approximately 80% of the ideal volume; at the 4-week follow-up, if additional volume is desired, the final 20% is added to reach perfection. Gradual accumulation produces more natural, safer results than single-session overcorrection.
Will temple filler make my face look bigger?
Absolutely not — the opposite is true: filled temples make the face appear smaller. Visual principle: when temples are hollow, the cheekbones visually protrude as the widest transverse facial point, and perceived facial width equals the bizygomatic distance — creating a wide-face impression. When temples are filled to form a smooth transition with the cheekbones, the cheekbones are no longer visual outliers; perceived facial width shifts upward from the cheekbones to the narrower temples and above — the face visually becomes narrower and more refined. In Korean aesthetics, this effect is known as V-line without surgery. Additionally, full temples create a smooth frontotemporal transition — the face appears rounded rather than angular from every angle.
