Does Radiesse Define the Jawline Right Away? Results, Risks and Cost in Gangnam

Quick answer: Radiesse places calcium hydroxylapatite (CaHA) particles that correct exactly where and as much as they're injected, so it's used where you want a contour fixed now, like the jawline. The trade-offs are a period of firmness or lumpiness and a small but serious vascular risk. At REPIC Clinic in Gangnam, Seoul, it starts at 990,000 KRW for 1 syringe (November 2026, VAT not included).

I'm Dr. Jay (Yongheon Ha), a doctor at REPIC Clinic in Gangnam. A lot of people come in thinking of Radiesse as a "collagen booster." In the consult room, the first thing I tell them is that it behaves much more like a filler. You see the shape the same day. Which means where it goes, and how much, decides the result.

What is Radiesse?

Radiesse is a gel carrying calcium hydroxylapatite particles 25–45 μm in size. It corrects 1:1: the volume you inject is the volume you get, right there. It's often grouped with collagen boosters, but in practice it's a filler-type product that corrects on injection. That's where it parts ways with Sculptra, which sits in the same category. Sculptra changes gradually over weeks; Radiesse changes on the day. No waiting. The flip side is that every decision made during injection shows up directly in the result.

Will my jawline look different right after Radiesse?

Yes. It corrects on injection, so the change in contour appears on the day. In the US, it's approved for facial wrinkles and folds, including nasolabial folds, and for jawline contour. The jawline trial allowed a top-up 4 weeks after the first injection. The idea is to add only what's still missing rather than put everything in at once.

But does every soft jawline need Radiesse? No. I look first at why the jawline has blurred. Has volume dropped out so the line breaks, or has tissue sagged down and covered the line? In the first case, filling reconnects the line. In the second, adding more just makes the lower face heavier. Then I talk about lifting first, not filling.

Is it used for smile lines too?

Yes, for nasolabial folds. In the trial, it was injected in up to 3 sessions at weeks 0, 2 and 4. Our Radiesse package is registered as "face, neck lines and back of hands," and the price is set by the number of syringes. Which area gets how many syringes is decided after the exam. The lips and eye area are different. Safety there hasn't been established, and nodules have been reported in the lips, so I don't recommend it for either.

How long does Radiesse last?

In the jawline trial, 67% of people who had responded at 12 weeks were still responding at 48 weeks. For nasolabial folds, effectiveness was assessed up to 6 months. Nothing beyond 3 years has been studied. So the confirmed period differs by area: 48 weeks for the jawline, 6 months for the folds. That's as far as I'll quote, and after that we decide on top-ups based on how you look.

What are the side effects and risks?

Swelling, redness and bruising are common, reported in 60–85% of people. Along the jawline, firmness and lumpiness were reported in the 70% range. Most of it settled within 14 days. Expect to feel it under the skin for a while. If you have an important event right around the corner, it's better to move the date.

There are rare but serious complications too. Vascular occlusion, skin necrosis and vision loss have been reported after market release. That's why, with this treatment, most of the time goes into deciding the injection point and depth.

Two more things. Delayed inflammation has been reported after infections, vaccinations and dental work. And Radiesse shows up on CT and X-ray, so tell the medical staff before any scan. After treatment, avoid strong sun and heat for about 24 hours or until the swelling goes down. If you have a flight home, tell us your departure date at the consultation and we'll plan the treatment day around it.

Who shouldn't get Radiesse?

It's contraindicated if you have a history of severe allergies, hypersensitivity to its ingredients or to lidocaine, or a bleeding disorder. We don't treat during pregnancy or breastfeeding. Safety under 18 hasn't been established. Aspirin and warfarin can increase bruising, so let us know what medication you take in advance.

Even without a contraindication, I don't recommend it for a jawline blurred mainly by sagging, or for the lips and eye area. Honestly, Radiesse suits people who want a clearly defined line more than people who want a slow, subtle change. If slow and subtle is what you're after, read our Sculptra comparison first.

How we do it at REPIC

We start by working out why the jawline has blurred: lost volume or sagging. We check skin thickness at the same time. If filling will solve it, we set the number of syringes and the injection layer, and the doctor injects personally. We don't fill everything in one go. Once swelling and lumpiness have settled, we look again and top up only where something is still missing. If filling won't solve it, we tell you so on the spot and talk about other options.
