Contour Injections for the Face in Korea: What They Actually Are
On a Korean clinic menu, a contour injection (윤곽주사) usually means a fat-reducing injection for the cheeks, jawline and double chin, not a filler. Here is what goes into it, what is approved in Korea, the risks, and what to ask.

What is a contour injection?
In Korea, a contour injection (윤곽주사, yungwak jusa) is a series of small injections into facial fat, usually in the cheeks, along the jawline and under the chin, meant to reduce fat and puffiness so the lower face looks slimmer. It belongs to the fat-dissolving injection family. It is not a filler: filler adds volume, a contour injection is meant to take some away.
What a contour injection is in Korea
English-language pages often use “contour injection” to mean filler placed along the cheekbones or jaw. Korean clinic menus use 윤곽주사 differently: it sits next to fat-dissolving injections (지방분해주사) and is offered for round cheeks, a soft jawline and fat under the chin. If you ask for a contour injection in Seoul, this is what you will most likely be offered, so check the Korean menu name before comparing quotes.
The injections go into the fat layer with a fine needle, at several points per area. The session itself is short, and the change is gradual rather than visible when you leave, because the aim is to shrink fat and swelling over the following weeks. Expect the area to look fuller for a few days first, from swelling.
For the same group of treatments on the body as well as the face, see our guide to fat-dissolving injections in Korea, and for what can go wrong afterwards, contour injection side effects.
What is in the syringe, and what is approved
There is no single standard formula. Korean medical information pages describe mixtures that vary from clinic to clinic and commonly combine ingredients such as aminophylline, hyaluronidase and choline alfoscerate, and in some recipes a steroid such as triamcinolone. Ask for the ingredient list of the exact mix you will receive, not just the clinic’s name for it.
Only one type of fat-reducing injection is approved in Korea for this purpose: deoxycholic acid. The Ministry of Food and Drug Safety (MFDS) approved Daewoong’s Violette in August 2021 for improving moderate to severe fat under the chin in adults. That approval covers the area under the chin, not the cheeks or the jawline.
Mixtures injected elsewhere on the face are used off-label. In 2024 Korea’s National Evidence-based Healthcare Collaborating Agency (NECA) reviewed the research on fat-dissolving injections and concluded that the effectiveness and safety of the off-label mixtures used in clinics were difficult to judge from the evidence available.
In practice, that means a contour injection can be a reasonable thing to try for mild fullness, but it is not an approved treatment for facial contouring, and results from one clinic’s recipe tell you little about another’s.
Where it is used, and where filler fits instead
Clinics usually offer contour injections for the cheeks, the jawline, the double chin and the area beside the mouth. Because the injection acts on fat, it suits people whose fullness comes from soft tissue. It will not narrow a wide jaw caused by the chewing muscle (clinics use botulinum toxin for that) or by bone.
If the face looks flat or hollow rather than full, a fat-reducing injection is the wrong tool and can make hollows more visible. That is where filler comes in: hyaluronic acid or calcium hydroxylapatite placed along the cheekbone, chin or jaw to add structure. Some clinics loosely call that “contouring” too, which is why the menu name matters.
Filler and fat-reducing injections are sometimes combined in one plan, for example reducing fat under the chin and adding a little chin projection. Ask which product goes where, and in which order.
Ask the clinic to write down whether you are getting a fat-reducing injection, a filler, or both, with the product names. A quote for one is not comparable with a quote for the other.

Risks and who should not have it
Swelling, bruising, tenderness and small lumps at the injection points are common and usually settle within about a week. Korean medical information pages also list less common problems: dents or hollowing where too much fat is lost, dizziness or palpitations, and, with mixtures that contain a steroid, irregular menstrual bleeding.
Where the injection goes matters. In September 2026 the US FDA strengthened the warnings for deoxycholic acid (sold there as Kybella) after reports of blurred or reduced vision, facial paralysis and other nerve problems when it was injected outside the area under the chin, including near the eyes, and of lumps lasting months. Be cautious about any fat-dissolving injection offered close to the eyes.
If filler is part of the plan, the most serious risk is different. Filler injected into or against a blood vessel can block it. That can cause skin death and, rarely, permanent blindness or stroke, so the clinic should keep hyaluronidase (the enzyme that dissolves hyaluronic acid filler) on hand and know how to use it at once. Careful technique reduces this risk; it does not remove it.
Tell the doctor if you are pregnant or breastfeeding, have an active skin infection in the area, take blood thinners, or already have little fat in the face. Treatment is generally not advised in pregnancy because its safety has not been studied there, and a thin face is more likely to end up looking hollow.
Results, sessions and price
Right after
Swelling, so the treated area often looks fuller for a few days before it looks slimmer.
When change shows
Gradually, over the weeks after a session. Clinics usually suggest a course of several sessions a few weeks apart rather than one.
How long it holds
Deoxycholic acid destroys the fat cells it reaches under the chin, though weight gain can still enlarge the fat that remains. For the mixed facial injections there is no reliable published data on how long the effect lasts, so treat any number of months a clinic quotes as its own estimate.
Price
We have no dated, sourced price observation for contour injections, so we do not quote one. Ask for the Korean-language menu price per session and per area, and how many sessions it covers.
Who sees less change
People with little facial fat, or whose width comes from muscle or bone, usually see little change and are more at risk of hollowing.
Questions to ask the clinic
How to vet a specialist
Ask these before you book. 1. Check the doctor: ask who will inject you and whether they are a board-certified specialist (전문의), for example in dermatology or plastic surgery. Many aesthetic clinics in Korea are run by doctors from other specialties, and the clinic’s Naver Place page often lists this.
- Ask for the formula: the ingredients and amounts in the mix, and whether any of them is a steroid.
- Assess the consultation: the doctor should check whether your fullness is fat, muscle or bone, and explain risks and alternatives.
- Confirm what is approved: ask whether the product has MFDS approval for the area being treated. Deoxycholic acid is approved for under the chin only.
- Plan for problems: ask who to contact after hours and, if filler is involved, whether hyaluronidase is kept at the clinic.
