Small pockets of subcutaneous fat on the face, upper arms, thighs or abdomen are what a fat dissolving injection in Korea is designed for: a solution placed directly into the fat layer during a 10–15 minute visit, with no anesthesia. ENTER Plastic Surgery prices it by area, and the clinic plans 3–5 sessions spaced 2–4 weeks apart.

Is it for you?
Who fat dissolving injections suit
Injection lipolysis acts on one tissue only: the soft fat that sits between the skin and the muscle. That makes it a tool for contour, for a pocket that has stayed put through diet and exercise, and not a way to lower body weight. The amount it can change in a session is modest, which is why a plan is built around several visits.
Two things decide whether the result will look the way you hope. The first is skin quality, since the skin over a thinner fat layer has to contract on its own; the injections do not lift or tighten it. The second is what the bulge is made of. The clinic notes that the solution works on fat and leaves muscle alone, so a fullness that comes from muscle, for example a cheek that bunches when you smile, stays as it is.
Usually a good fit
- A pinchable fat pocket that stays despite a stable weight
- Fullness along the jawline or lower cheeks caused by fat
- A defined area of fat on the upper arms, thighs or lower belly
- Skin with enough elasticity to settle over a thinner fat layer
- Able to return for repeat visits 2–4 weeks apart
We may suggest waiting
- Loose or sagging skin as the main concern
- Bulk that comes from muscle, such as a bulge when smiling
- Wanting overall weight loss
- Pregnancy or breastfeeding
- Infection, rash or inflammation at the planned site
- Large fat volumes that call for liposuction
How it works
How fat dissolving injections work in the fat layer
Fat cells store energy as droplets inside a thin outer membrane. A lipolytic solution injected into the fat layer breaks that membrane down, and the body's own clean-up process, mainly inflammation followed by removal through the lymphatic system, clears the debris over the following weeks. Fewer fat cells remain in the treated spot, so the contour flattens gradually rather than on the day of the injection.
ENTER Plastic Surgery has not published the product used in its injections, so this page does not name an ingredient. The most closely studied agent in this field is deoxycholic acid. In a phase 3 randomized trial of injections under the chin, deoxycholic acid reduced fat compared with placebo (Jones, 2016). That trial is background on how injection lipolysis works; it is not a study of the clinic's own solution.
The price list is organized by volume as well as area: one facial area is a single line, while body areas are measured in cubic centimeters of solution, 40 cc for the arms, 80 cc for the thighs, 120 cc for the abdomen and 240 cc for a full-body plan. A larger area needs more solution to reach the whole fat layer, not a stronger dose in one spot.
Pinch test and mapping
At consultationThe thickness of the fat is checked between the fingers, loose skin and muscle bulk are ruled in or out, and the treatment zone is outlined.
Marking the grid
The skin is cleansed and a grid of injection points is drawn so the solution spreads evenly through the fat instead of pooling in one place.
Injections into the fat layer
10–15 minutesA fine needle places small amounts of solution at each point. No anesthesia is used; stinging, warmth or pressure are the expected sensations.
Back to your day
Same dayYou can wash and wear makeup the same day. The next session is booked 2–4 weeks later, once swelling has settled and the area can be judged again.

Prices
What fat dissolving injections cost per area in South Korea
Each line in the price list below is one session for one area. The face is charged per area, and body areas are charged by the volume of solution, so a series of three sessions on the arms means three arm lines. Every amount is shown before VAT (10% VAT is added at payment). If you want two areas in the same visit, ask for both to appear as separate lines on your written quote so the total for the whole series is clear before you travel.
Prices exclude VAT (10% VAT is added at payment).
Recovery
Between sessions: what to expect after fat dissolving injections
Swelling and tenderness start within hours. Face washing and makeup are fine the same day, and most daily plans can go ahead, including a flight.
Swelling lasts about a day; bruising is minimal for many people but varies. A firm or tender patch under the skin can take longer to soften.
This is the window for the next session. The area is checked again, and injection points move toward the fat that remains.
The contour keeps changing for some weeks after the final visit. Keeping your weight stable matters, because remaining fat cells can still grow.
Safety
Side effects of fat dissolving injections
Swelling, soreness and a numb or firm feeling are the expected effects of injection lipolysis, and they settle on their own. A meta-analysis of randomized trials of deoxycholic acid found that it reduced fat but came with more pain, swelling, firmness, nodules and altered sensation than placebo, and judged the certainty of evidence low to moderate with a possible industry bias in every trial (Inocêncio, 2023).
- Swelling, redness, bruising and tenderness at the injection points.
- Numbness or tingling over the treated area for a period.
- Firm areas or small nodules under the skin while the tissue heals.
- An uneven contour if fat shrinks more on one side or in one spot.
- Near the jawline, temporary weakness of the lower-lip muscle, which can make a smile look uneven.
- Rarely, skin ulceration, hair loss over the site or a blocked blood vessel, reported after market release of deoxycholic acid (Metzger, 2020).
A systematic review of serious adverse events stresses keeping the solution out of the skin itself and separating fat from loose skin before treatment, because sagging is a surgical problem (Shridharani, 2024). Call the clinic straight away about pain that keeps increasing, skin that turns dusky or pale, or a wound that opens.

FAQ
Fat dissolving injections in Seoul: questions answered
How long is the downtime after fat dissolving injections?
Swelling lasts about a day, and you can wash your face, wear makeup and return to your routine the same day. Bruising is minimal for many people but varies. A tender or firm patch under the skin can take a little longer to soften.
Can I fly home the day after a fat dissolving injection?
Yes. The clinic's guidance is that flying is possible the same day or the next day. Because a full plan is 3–5 sessions spaced 2–4 weeks apart, visitors from abroad can do one session per trip or plan the series around return visits to Seoul.
Who carries out fat dissolving injections at the clinic?
The injections are given at ENTER Plastic Surgery by the clinic's medical team. Dr. Choi Yul, a family medicine specialist, focuses on Botox, injections and pigment treatment at the clinic. When you book, ask who will be treating you on the day.
Is VAT included in the fat dissolving injection price?
No. Each area is listed before VAT, so 10% VAT is added at payment; for example, one facial area is ₩200,000 + VAT per session. Prices are per session, so multiply by the number of sessions in your plan.
How do I book fat dissolving injections from overseas?
Use the form on this page or message us on WhatsApp, and we will get back to you as soon as possible. English-speaking staff are available at the clinic. Mention the areas you want treated and your travel dates so the sessions can be spaced around your trips.
Is there a deposit or a cancellation policy?
Deposit and cancellation terms are set for each booking and are not published on this page. Ask for them in writing before you pay, and check how a change of date would affect the spacing of the remaining sessions in your series.
What is in the fat dissolving injection?
The clinic has not published the product name, so this page does not state an ingredient. Studies on injection lipolysis mostly test deoxycholic acid, which is cited here as background. Ask for the product name and its ingredients in writing before your first session.
Do fat dissolving injections hurt?
No anesthesia is used, and the injections are given with a fine needle. Stinging, warmth or a sense of pressure during the 10–15 minute visit are expected, and the area can stay tender for a day or so afterward.
Will the fat come back after fat dissolving injections?
The treated fat cells are reduced in number, and the clinic describes the result as lasting while your weight stays stable. The fat cells that remain can still enlarge with weight gain, so the area can fill out again if your weight rises.
Can fat dissolving injections be used on the arms?
Yes. The upper arms are one of the listed body areas, priced per 40 cc session. The same approach is used on the face, thighs and abdomen, each priced as its own line, and a full-body plan uses 240 cc per session.
Are fat dissolving injections a weight-loss treatment?
No. They reduce a local pocket of fat and do not lower body weight in a meaningful way. If your goal is weight loss across the body, the injections do not replace changes in diet and activity, and large volumes are a question for liposuction.
Can fat dissolving injections tighten loose skin?
No. The solution acts on fat, not on skin, so skin that already sags will not tighten after the fat thins. When looseness is the main concern, a lifting treatment or surgery is the conversation to have instead.
