Double Chin Injection in Korea for a Sharper Jawline: Liron's “Emergency” Trip, Explained by Her Doctor

When a patient points under their chin and says “this,” I already know half of the consultation. I'm Dr. Hyunji Kim, director of Delphic Clinic close to Sinnonhyeon Station in Gangnam. I trained at Korea University Medical Center and consult and treat international patients myself. A softer jawline is one of the concerns I hear most from travellers, and Liron put it more memorably than most: her “emergency” was a snatched jawline. This page explains why the small chin injection mattered as much as the devices, what it costs, and who would be better off with something else.

Where a soft jawline actually comes from

A jawline can look blurred for three different reasons: a pad of fat under the chin, skin that has loosened, or both. The fix is different for each, which is why Liron's visit started with the AI skin analysis and a 1:1 consultation rather than a device.

Her plan — a chin injection plus two devices — is the one I build when fullness under the chin leads and some laxity follows. That ranking decides the order of everything else.

The chin injection: small, targeted, easy to underestimate

A double-chin fat-dissolving injection works on the fat pad directly. Devices can warm and tighten a broad area, but a precise injection reaches the pocket that creates the double-chin shadow.

I explain the dosing and areas in my guide to fat-dissolving injections for the jawline, and the honest list of side effects is in a separate piece on what the reviews understate.

Why Titanium and ONDA came along

• ONDA's Coolwaves™ microwaves heat the deeper fat layer along the lower face while keeping the surface cool — useful where the heaviness extends past the chin.
• Titanium warms the dermis with three wavelengths (755, 810, 1064 nm) to firm the skin, so the new contour doesn't sit under loose skin.
• She also had a small add-on injection, quoted at the consultation; it is separate from the jawline plan.

“Quick, with minimal pain” — what to actually expect

Liron's description fits what many patients tell me. The injections take only a few minutes and feel like small pinches with a brief sting. Titanium's sapphire tip cools to around −3°C, and ONDA feels like deep warmth.

Expect the area under the chin to feel swollen or tender for a few days, and occasionally a small bruise. The swelling is the reason early “snatched” photos and the final result are not the same thing.

Pricing her plan on today's menu

Our prices are public, and visitors pay exactly what Korean patients pay. The typical first-visit version of Liron's plan is:

If you only want the chin, the injection can be done on its own. My area-by-area fat-dissolving price map shows how other areas compare.

What happens after the swelling goes down

The fat-dissolving effect develops over the following weeks, while device tightening builds over a couple of months. Some people need more than one injection session for a fuller chin, which I'll tell you upfront rather than after.

Planning it around a short trip

1. 1

   Before flying

   Message us on WhatsApp with a side-profile photo. That one angle tells me most of what I need about the chin.

2. 2

   Treatment day

   Skin analysis, consultation with me and same-day treatment if we agree. English and Chinese interpreters are on site.

3. 3

   Location

   A short walk from Exit 3 of Sinnonhyeon Station.

4. 4

   Timing

   Book early in your trip, not the day before a big event — chin swelling takes a few days to settle.
