A fat dissolving injection, also called injection lipolysis, is a non-surgical treatment that targets small, stubborn pockets of localized fat that resist diet and exercise. A doctor injects a lipolytic solution, typically deoxycholic-acid-based, directly into the fat layer of a defined area such as under the chin, the jawline, or small bra-line and abdominal pockets. Over the following weeks the disrupted fat cells are cleared by the body, so the treated area looks slimmer and more contoured.
It is important to frame this correctly: a fat dissolving injection is a contouring tool for small, specific areas, not a weight-loss treatment and not a replacement for a healthy lifestyle. It suits people who are close to their target shape but have a defined pocket that will not budge. Because it works cell by cell over a series, results build gradually and vary from person to person depending on the area, the amount of fat, and individual response.
At our Gangnam (Seoul) location, fat dissolving treatment is consultation-led. Dr. Yoongon Ryu assesses whether your concern is genuinely a localized pocket suited to injection lipolysis, then plans the number of sessions and explains realistic expectations in English. International patients are supported throughout, and Gangnam sits about 2 minutes from Gangnam Station exit 10, making a short series easy to schedule during a Seoul visit.
Fat dissolving injections rely on a detergent-like action on fat-cell membranes. The active agent is usually deoxycholic acid, a naturally occurring bile acid that disrupts the membrane of adipocytes (fat cells) in the treated area, causing them to break down. Once the cells are destroyed, the released fat and cell debris are gradually cleared by the body’s normal metabolic and immune processes over several weeks, which is why the slimming effect appears progressively rather than instantly. Because the action is localized to where the solution is placed, precise, evenly spaced micro-injections across the fat pocket matter for a smooth result — this is why the treatment is doctor-administered. A course typically runs 2 to 6 sessions spaced about 4 to 6 weeks apart, allowing the treated area to settle and the body to clear fat between visits. Expected swelling in the days after each session is part of the process. The clinic’s doctors match the number of sessions, injection depth, and area to your anatomy, since response varies with the size of the pocket and individual metabolism.

Dr. Yoongon Ryu confirms whether your concern is a genuine localized pocket, since this is 1 tool for defined areas, not overall weight loss.
The solution is placed as evenly spaced micro-injections across the fat pocket, so a smooth result depends on precise, doctor-led delivery.
A deoxycholic-acid-based solution breaks down adipocyte membranes across the treated pocket within the first minutes of the 15 to 30 minute session.
The body removes the disrupted fat gradually, so slimming appears over roughly 4 to 6 weeks between each of the 2 to 6 sessions.
Most areas need 2 to 6 sessions spaced 4 to 6 weeks apart, with results building progressively and varying between individuals.

At our Gangnam (Seoul) location, Dr. Yoongon Ryu confirms in English whether your concern is a localized pocket suited to injection lipolysis and sets realistic expectations.
After marking, the area is treated with evenly spaced micro-injections, usually taking about 15 to 30 minutes per session.
Treatment runs as a course, so most areas need 2 to 6 sessions spaced about 4 to 6 weeks apart to let fat clear between visits.
Slimming builds gradually over several weeks after each session as the body clears the disrupted fat, and results vary by individual.
Treated fat cells that are cleared do not return, but a stable weight and healthy lifestyle are needed to keep the contour, since remaining cells can still enlarge.



A fat dissolving injection, or injection lipolysis, uses a deoxycholic-acid-based solution injected into a small, localized fat pocket to break down fat cells, which the body then clears over weeks. It contours defined areas like under the chin, not overall body weight. You can learn more on our slimcut injection page.
No, fat dissolving injection is a contouring tool for small, defined pockets of localized fat, not a weight-loss method or a substitute for diet and exercise. It suits people already near their target shape with a stubborn area that resists lifestyle efforts. Your doctor confirms at consultation whether your concern is genuinely a localized pocket.
You can receive fat dissolving injections at our Gangnam (Seoul) location, about 2 minutes from Gangnam Station exit 10, where Dr. Yoongon Ryu consults in English. Reberry Clinic also has Myeongdong and Incheon Airport locations, so international patients can choose the site that best fits their Seoul itinerary and follow-up sessions.
Common areas are small, defined pockets such as under the chin, the jawline, and modest bra-line or abdominal pockets. The treatment works best on precise, stubborn areas rather than broad regions. Your doctor assesses each area at consultation and, for larger pinchable bulges, may suggest a different tool like RF body tightening or fat freezing instead.
You may feel brief stinging or burning as the solution is injected, followed by swelling, warmth, and tenderness in the days after. Numbing options help with comfort during the session. Most patients tolerate it well, and your doctor explains the expected post-treatment swelling so you can plan around it before your session.
Expect swelling, tenderness, and sometimes bruising in the treated area for several days, which is a normal part of how the treatment works. There are no incisions, so most patients continue daily activities while the area settles. Under-chin treatment can look puffy briefly, so many international patients time sessions with this in mind.
Most areas need 2 to 6 sessions spaced about 4 to 6 weeks apart, since fat is cleared gradually and results build across the series rather than in one visit. The exact number depends on the pocket size and your response, which your doctor reviews between sessions. Some smaller areas need fewer sessions.
Slimming appears progressively over several weeks after each session as the body clears the disrupted fat, not immediately, and initial swelling can mask early change. Most patients notice a difference across the course rather than after a single injection. Results vary with the area, the amount of fat, and individual metabolism, as your doctor explains upfront.
Fat cells that are broken down and cleared do not come back, but remaining cells in the area can still enlarge if you gain weight, so a stable weight keeps the contour. It is not a one-time fix for lifestyle. Your doctor plans your slimcut injection series and whether occasional touch-ups suit you.
Common effects are swelling, bruising, tenderness, redness, and temporary numbness at the treated site, most of which are localized and settle over days to weeks. Trials report the majority of adverse events stay at the injection area. A consultation screens for contraindications such as bleeding tendency or infection to reduce risk before treatment.
Cost depends on the size of the area and how many sessions your plan needs, since a small under-chin pocket differs from a larger area needing more visits. Because plans are individualised, the clinic’s doctors confirm your cost transparently at consultation. You can start on our slimcut injection page.
You are likely suitable if you are close to your target shape and have a small, stubborn, localized fat pocket, and if you have realistic expectations about gradual, variable results. A consultation confirms this. It is not suitable for overall weight loss, during pregnancy, or with certain medical conditions, which your doctor reviews carefully first.
Fat dissolving injection suits small, precise pockets; fat freezing suits larger pinchable bulges; and surgical liposuction removes more volume in one procedure with more downtime. Your doctor recommends the best fit for your anatomy and goals. For firmness rather than fat, an RF body tightening approach may be more appropriate.
Yes, it can be paired with skin-tightening treatments when both fat and mild laxity are concerns, and staged with other body-contouring tools. Your doctor sequences everything so the area is not overloaded. Some patients follow their series with a body rejuvenation plan to refine skin quality around the treated area.
Expect to manage swelling with your doctor’s guidance, avoid vigorous massage of the area unless advised, and keep the skin clean while it settles. Staying at a stable weight preserves the result. Your doctor gives specific aftercare instructions for the treated area and tells you when swelling should subside before your next session.
For a single session, 1 to 2 days is usually enough, though under-chin swelling can be visible for a few days afterward, so allow buffer time if that matters for photos or events. Because the plan runs as a series, many international patients begin in Seoul and return for later sessions on subsequent trips.
Yes, flying within a day or two is generally fine, since there are no incisions, though you may still have swelling and tenderness while you travel. Stay hydrated and follow your aftercare instructions in transit. Your doctor advises on managing swelling and when your next session should be scheduled, including remote follow-up from abroad.
