When you wear your hair down, your face always looks round and wide. When you tie it up in a ponytail, your ears seem to “stick” to your head – the opposite of protruding ears. Your glasses constantly slide down, and you have to push them up a hundred times a day. In photos, you always have to tilt your head to show a bit of ear, otherwise your face looks like a flat pancake. There’s a popular saying: “Ear position determines face size – the less ear visible, the bigger your face looks.” Elf ear filling (ear base augmentation) – a “bone‑structure fine‑tuning” procedure that has been popular in Seoul’s Gangnam district for years – is now rapidly gaining attention among discerning women in Singapore and Malaysia. But how exactly is it done? How long does it last? Are there side effects? Today, we’ll lay out the doctor’s full protocol.
Elf ear filling (ear base augmentation) involves injecting hyaluronic acid or biostimulatory fillers behind the ear (at the ear base and along the posterior ear crease) to increase volume, thereby enlarging the cephalic angle (the angle between the ear and the side of the head) from a flat 15°–20° to a more aesthetically ideal 30°–45°, making the ears naturally “project” from the front view. It is completely different from protruding‑ear surgery – surgery removes excess tissue to make the ears stand out, while filler adds volume behind the ear to push it outward. Think of it like placing a wedge behind a door that’s flush against the wall – the door swings open naturally, but the door itself remains completely untouched.
Step 1: Pre‑treatment aesthetic marking – finding your “golden angle”
The doctor will have you sit upright looking straight ahead, and use a measuring tool and marker to outline the key points of the concha, scapha, and retroauricular groove behind the ear. Most importantly, they measure your current cephalic angle and design a target angle based on your face width and zygomatic arch width – bigger is not always better. The ideal outcome is that, from the front, about 3–5 mm of the ear rim is visible, creating the “head‑wraps‑face” effect. This design process takes about 10 minutes and determines whether the final result looks “sophisticated” or “accidentally protruding.”
Step 2: Layered injection technique – “dual‑plane” filling at periosteal and subcutaneous layers
Korean doctors typically use a combination of sharp and blunt cannulas. First, a sharp needle is used to inject high‑G’ cross‑linked hyaluronic acid into the periosteal layer (the deepest layer, near the bone) over the mastoid process behind the ear – this provides the foundational lift that pushes the entire auricle outward, using about 0.5‑1 ml per side. Then, a blunt cannula is used to fan‑shape the subcutaneous layer, filling the retroauricular depression to create a smooth transition. The procedure is alternated between both ears, with the doctor repeatedly asking you to sit up and check the front view. Injection time per side is about 15 minutes.
Step 3: Immediate molding and compression fixation – avoiding “lumps”
After injection, the doctor uses finger pads with sterile gauze to mold the area in the opposite direction, ensuring the filler is evenly spread and the edges are smooth with no stepping. Then, medical tape is applied behind the ear in an “L‑shaped” support to keep the filler stable in the correct position for 72 hours, preventing displacement from sleeping pressure. When you look in the mirror, you’ll see that your ears now “stick out” a little, and your face instantly looks smaller.
| Aspect | High‑G’ HA Fillers | Biostimulatory Fillers (e.g., Radiesse, Ellansé) | Surgery (implant/cartilage) |
|---|---|---|---|
| Duration | 12‑18 months (depending on metabolism) | 24‑36 months (stimulates collagen) | 5‑10 years (permanent) |
| Reversible | ✅ Dissolvable (hyaluronidase) | ❌ Not fully dissolvable (some have disaggregators but technically difficult) | ❌ Requires second surgery to remove |
| Firmness/support | ★★★★☆ (high G’) | ★★★★★ (inherent scaffold) | ★★★★★ (firmest) |
| Trauma & recovery | Minimally invasive (pinprick, 3 days swelling) | Minimally invasive (slight swelling, 1 week) | Invasive (anaesthesia, bandaging, 1 month recovery) |
One‑sentence summary: HA fillers are “trial size” – flexible and safe, ideal for first‑timers; biostimulatory fillers are “upgrade size” – longer‑lasting and natural, great value; surgery is “permanent size” – for those who have decided on a lifelong change. For the vast majority, HA fillers are the most worry‑free entry point to elf ear enhancement.

🔑 Official answer on “how long does it last”:
Duration depends entirely on the material chosen. When using high‑G’ HA fillers (e.g., Juvederm Voluma, Restylane Lyft), because the retroauricular area has low mobility and relatively less blood supply, metabolism is slower than in other facial areas, typically lasting 12‑18 months. If biostimulatory fillers (e.g., Radiesse, Ellansé S) are used, they stimulate natural collagen production, extending the duration to 24‑36 months. Korean doctors recommend: first‑timers start with HA fillers; if satisfied and you don’t want frequent touch‑ups, you can layer biostimulatory fillers on the second session for long‑term support.
Post‑treatment care:
Back to the initial question – elf ear filling is like turning on a “side light” for your facial contours. Without changing bone structure or facial features, it can make your face appear smaller and elevate your overall refinement. It lasts long enough (1‑3 years) and most side effects are manageable. However, it cannot fix severe zygomatic arch protrusion or masseter hypertrophy – it is better suited as a “finishing touch” for bone‑structure fine‑tuning.
Final advice: If you naturally have flat ears and have the budget, elf ear filling is a worthwhile long‑term “slimming accessory.” But remember – the injection plane (supraperiosteal vs. subcutaneous) determines whether you get an “elf” or a “monster” – always choose a doctor with experience in periauricular injections.
