Chin InMode Korea for a double chin: when it does not fit, risks and options
InMode works on fat under the skin and on the dermis, and it does not change the shape of the chin bone. Its infrared sensor keeps the skin surface below 43 °C during treatment.

A double chin that still shows in photos even after you lost weight: is “chin inmode korea” really the answer, or does your chin problem sit in a different layer?
If your leave for Seoul is already approved and InMode is on the list, the section on who should wait is the one to read before you book.
What InMode can and cannot change under the chin, how long the redness and warmth usually last, which conditions make waiting the better call, and what the options are if your chin needs something else: these four things decide whether InMode belongs in a short trip.
Hello, I'm Dr. Jang Dong-hoon, Founder & Medical Director of THE Beautiful Clinic in Seoul. I am a member of the Korean Society of Aesthetic Surgery and the Korean Society for Laser Medicine, and my profile is on the our doctors page.
At our clinic I consult, plan and treat myself. The consultation begins with a 3D scan of your skin, not with a price list. Clinic staff interpret for international patients at no charge.
Many people assume every double chin is fat, yet part of it can come from skin that has started to loosen, the neck muscle, or a chin that sits back.
The short answer: InMode can help a double chin that is mostly fat under the skin, as long as the skin is still fairly elastic, and the effect lasts about 6 months. It does not bring a short chin forward and does not replace surgery for very loose neck skin.
If you are not sure which kind yours is, send one side photo taken in daylight on WhatsApp, face looking straight ahead, and ask one thing: does what shows in the photo look more like fat or loose skin. You can write in English or Bahasa Indonesia.
What InMode does under the chin
InMode combines radiofrequency (RF) with a high-voltage pulse, or HVP. The pulse acts on the fat cell membrane, while multipolar RF handles collagen remodelling in the dermis above it. So it aims at two layers at once: the dermis and the fat under the skin.
On the face there are two handpieces. Mini FX draws tissue into the handpiece so the energy reaches the SMAS for contour, and this is the part that relates to the chin and jawline. FORMA works the dermis for texture and fine lines. Most plans use both. Device details are on the InMode treatment page.
On safety, the question people ask most is about heat. An infrared sensor checks the temperature a thousand times a second and keeps the epidermis below 43 °C. That lowers the risk of burns and blistering but does not remove it. It feels warm and moderate, and the downtime is minimal.
Where does your double chin come from?
Many results for “chin inmode korea” jump straight to the device, yet this question decides more. In a mirror, four different things can look the same.
| Source | What you usually see | InMode's role |
|---|---|---|
| Fat under the skin | A thick layer you can pinch under the chin, skin still firm | Its main target |
| Loose skin | Skin folds when you look down, thin pinch | Limited, needs other tightening |
| Receding chin | From the side, the chin tip sits far behind the lower lip | Does not change bone shape |
| Fat under the neck muscle | Still full even with a thin pinch | Usually hard to reach from outside |
Say you are 31, at a normal weight, and a double chin shows every time you are photographed from below. From the side, your chin tip sits far behind your lower lip. In that situation, reducing fat answers only half the problem: the neck angle gets a little sharper, but the chin still looks short. To me, that is the point to talk about chin shape, for example with Contour Filler, before or alongside InMode. For fillers, the US FDA lists risks such as bruising and swelling and, rarely but seriously, filler entering a blood vessel.
On the other hand, if you can pinch a thick layer under the chin, the skin springs back quickly when released, and the chin is in proportion from the side, InMode is one of the reasonable options to discuss.
Who should wait or skip InMode on the chin
A 2022 prospective study in Plastic and Reconstructive Surgery Global Open on bipolar RF for the lower face and the area under the chin excluded participants with certain conditions. Those are research criteria, but the list matches what should be discussed before RF on the chin:
- Implanted electrical devices such as a pacemaker or defibrillator.
- Implants that stay in the treated area, such as metal plates, screws or a silicone chin implant.
- A current or past skin cancer.
- A weakened immune system.
- Wound-healing problems, for example a tendency to keloids. If you have raised scars, mention them from the start.
- Skin treatment in the same area within the last 6 months, such as filler, microneedling or laser.
- Isotretinoin use.
Beyond that study's list, doctors generally also hold off energy-based treatment during pregnancy or breastfeeding, and when there is infection or inflamed acne on the chin. A face that is already very lean also needs a second thought, because reducing fat there can make the jawline look hollow.
What side effects are normal, and when should you worry?
After InMode, redness and warmth under the chin usually settle within a few hours. Mild swelling or tenderness when pressed can last one to two days. For most people, this does not get in the way of daily plans.
Less common are a small blister or a mild burn at one spot, especially if the skin is irritated. On medium to deep skin tones, a burn like that can leave dark marks after inflammation that take weeks to fade. Mention from the start if you use retinol or exfoliants, because irritated skin is more vulnerable.
Everyone reacts differently, so how long the redness lasts and what the result looks like cannot be promised the same for everyone.
If, after you are back in Jakarta or Surabaya, a blister appears, the area grows more painful, or the skin hardens, photograph it in daylight and send it on WhatsApp with your treatment date. If there is an open wound, fever or pain that keeps building, also see a dermatologist near you without waiting for a reply, and bring your treatment record from Seoul. While the chin is still red, use sunscreen and avoid strong heat such as saunas or midday sun.
If one of the conditions above applies to you, for example a chin implant or filler a few months ago, send the product name or date on WhatsApp and ask whether RF on the chin still makes sense for you. The clinic answers messages within 24 business hours, and on Saturdays the clinic is open from 10:30 to 16:30.
When your chin needs something else
We have several lifting devices that work at different depths, so the answer in a consultation is not always InMode. The options most often relevant to the chin:
- [ONDA](treatment:onda) uses Coolwaves microwave energy, and its 7 mm head reaches the fat of a double chin and the deep cheek. Its general risks are similar to other energy treatments: redness and, rarely, burns.
- Oligio is monopolar RF aimed more at skin tightening, without targeting fat. Its details are on the Oligio treatment page.
- Thread Lifting moves tissue physically through entry points, without an incision. Most patients are back to normal routine the next day, with swelling settling over the first week. Bruising, slight dimpling of the skin or a thread you can feel are the risks commonly discussed for thread lifts.
- Contour Filler for a receding chin, as in the example above.
If the width of your lower face comes from a large jaw muscle, RF does not shrink that muscle, so InMode is not the answer for that concern. If you are also thinking about fat on the abdomen or arms, the same principle of choosing the layer first applies.
How should you plan your days in Seoul?
The clinic is on the 2nd floor of the Jinryeong Building, 545-12 Gangnam-daero, Seocho-gu, a two-minute walk from Nonhyeon Station (Sinbundang Line) Exit 5. There is no patient parking, so come by subway or taxi.
Hours: Monday to Thursday 10:30 to 19:30, Friday 10:30 to 20:30, and Saturday 10:30 to 16:30 with no lunch break. On weekdays there is a lunch break from 13:00 to 14:00. Closed on Sundays and public holidays.
InMode's downtime is minimal, but placing treatment on your first or second day in Seoul gives you a few days to watch how your skin reacts before you fly home. There is no deposit, and changing or cancelling is free, so ask on WhatsApp along with your arrival date. General information for international patients is on the THE Beautiful Clinic home page, and you can choose a time on the booking page.
Before you book anything from a search for “chin inmode korea”, the easiest first step is to send two photos on WhatsApp, one from the front and one from the side, in daylight. Say whether you have had filler or an implant in your chin, then ask: “With this history, does InMode still make sense for my chin, or is there another option?” When you come, the consultation begins with a 3D skin scan, with clinic staff interpreting at no charge, and from there we work out together whether your chin needs less fat, firmer skin, or a shape that sits further forward.

- It is worth discussing when a double chin is mostly fat and the skin is still elastic.
- It does not bring a receding chin forward or replace surgery for very loose skin.

- First step: one daylight side photo of your chin on WhatsApp.
Questions patients ask
Does InMode on the chin hurt?
It usually feels warm and moderate. If the heat feels too strong at one spot, say so right away, because overheated skin is one of the ways a blister starts.
How many sessions does the chin need?
There is no single number for everyone. The number of sessions is discussed after the 3D skin scan, looking at the thickness of the fat and the elasticity of your skin. The effect lasts about 6 months, so also think about whether you plan to return to Seoul.
When can I fly home after InMode?
Downtime is minimal and redness usually settles within a few hours. What helps more is leaving one or two days in Seoul after treatment, so that if a small blister appears you can still come back to the clinic before you leave.
I had chin filler last year. Can I still have InMode?
Give the product name and date when you ask. The 2022 bipolar RF study mentioned above excluded participants who had filler, microneedling or laser within the last 6 months. Filler older than that is discussed by looking at where it sits and what type it is.
What decides the cost of InMode for the chin?
Four things: whether FX, Forma or both are used; the treatment time, because face InMode at our clinic is priced by a 10 or 15 minute duration; whether InMode is combined with another device; and whether you plan to repeat it after about 6 months. For the figure for your case, ask on WhatsApp with one side photo of your chin.
Will I see the result straight away?
Mild swelling on the first day can make the chin look unchanged. Fat reduction and collagen building usually happen gradually over several weeks, so the change in the mirror often shows after you are home.
Results and recovery vary between individuals, and every treatment can have side effects. Prices are from the clinic's price list and are confirmed at consultation. This article is general information, not a diagnosis.
