Visible change builds gradually over 4 to 6 weeks per session, with most patients assessing results after a series of 2 to 4 sessions.
Fat-dissolving injection before-and-after change is gradual: the treated area looks swollen at first, then slims over 4 to 6 weeks per session as the body clears destroyed fat cells. Most patients judge the full result after 2 to 4 sessions. Every photo is an individual case, so outcomes vary and are not a promise of your result.

A fat-dissolving injection, also called a lipolytic injection, reduces small, stubborn fat pockets such as the double chin or jawline by injecting a solution that disrupts fat-cell membranes. Before-and-after images show the difference between the starting contour and the result after the body has cleared those fat cells. The key thing to understand is timing: results are not visible immediately, and the same person may look slightly swollen in the early days before slimming becomes apparent.
The most studied active ingredient is deoxycholic acid, a naturally occurring molecule that destroys fat cells in the treated area; some formulations also use phosphatidylcholine. Because the destroyed cells do not return, the change captured in an honest after photo tends to be stable once a stable weight is maintained. A genuine before-and-after pair should use the same angle, lighting, and distance, and should note how many sessions and how much time passed.
Reberry Clinic discusses realistic expectations at consultation and plans these treatments with English-language support across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), with treatment overseen by the clinic’s doctors. Any images shown are individual cases, illustrative, and not a promise of your own outcome.
The active ingredient, most commonly deoxycholic acid, is a bile-acid molecule that disrupts the membrane of fat cells (adipocytes) on contact. Once the membrane is destroyed, the cell can no longer store fat, and the body clears the released contents through normal metabolic pathways over roughly 4 to 6 weeks. This biology is why before-and-after photos are taken weeks apart, not on the same day: in the first days the area is often swollen, and only as that settles and the fat clears does the slimmer contour emerge. The doctor maps a precise grid of small injection points across the target area, controlling dose and depth so the agent stays within the fat layer, which is what makes results both gradual and stable. You can review the full treatment on our slimcut injection page.

A before image is taken at consultation from a set angle, lighting, and distance for a fair comparison.
The lipolytic agent is delivered into the fat layer in a session lasting about 15 to 30 minutes.
For about 7 to 14 days the area looks swollen or fuller, so the early phase is not the result.
Over roughly 4 to 6 weeks the body clears the destroyed fat cells and the contour slims.
Most patients take the comparison photo about 4 to 6 weeks after the final of 2 to 4 sessions.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors confirm the area is suitable in English and take a standardised before photo at a set angle.
After mapping, the injection session takes about 15 to 30 minutes, with numbing applied for comfort.
Sessions are spaced roughly 4 to 6 weeks apart so swelling settles and fat clears between photos.
Slimming builds over 4 to 6 weeks per session; the meaningful after photo follows the full series.
Cleared fat cells do not return; a stable weight keeps the after-photo contour consistent over time.
Visible slimming builds over 4 to 6 weeks after each session as the body clears destroyed fat cells, so the meaningful after photo follows the series, not the same week. In a phase III trial, two-thirds of treated patients showed measurable submental fat improvement. You can review the treatment on our slimcut injection page.
Early swelling is a normal part of the response, so the area can look fuller for several days before it slims. This is why honest before-and-after photos are taken weeks apart rather than immediately. The swelling settles over one to two weeks as the body begins clearing the treated fat in the area.
Most patients assess a clear before-and-after difference after completing 2 to 4 sessions spaced about 4 to 6 weeks apart. Smaller pockets may respond in fewer sessions, while denser areas need the full series. Your doctor reviews progress between sessions and adjusts the plan to your response at each visit.
No, every before-and-after image is an individual case, so it shows what was possible for that person, not a promise of your outcome. Results vary with the amount of fat, skin quality, and number of sessions. A consultation gives a realistic idea of what your own area can achieve.
Look for the same angle, lighting, and distance in both photos, plus a note of how many sessions and how much time passed. Be cautious of images that look too perfect or that hide the timeline. Standardised, clearly labelled pairs are the most trustworthy way to judge realistic change.
The submental area under the chin (double chin) and the jawline tend to show the clearest contrast, since slimming there is easy to photograph. Suitability depends on fat thickness and skin quality, confirmed at assessment. You can explore options on our slimcut injection page before your visit.
Most patients feel brief stinging and warmth as the solution is injected, eased with numbing measures. Afterwards the area can feel tender or swollen for a few days, which is part of the early phase you see before the after photo. Discomfort is temporary and your doctor adjusts the pace for comfort.
Expect swelling, tenderness, and sometimes bruising for several days, so the area will not photograph at its best straight away. Most people continue daily activities but plan photos for later. Swelling under the chin can be noticeable initially, then settles over the following one to two weeks before slimming shows.
Yes, the treated fat cells are destroyed and do not regenerate, so the contour in an honest after photo is long-lasting rather than a one-time fix that fades. Remaining cells can still enlarge with weight gain, so a stable weight keeps the result consistent. Pairing with RF body tightening can refine the area.
Yes, fat-dissolving injections are often paired with skin-tightening to address both fat and mild laxity, which can make the after contour look smoother. Many patients add RF body tightening after contouring. Combining treatments helps the skin adapt as the fat reduces in the treated area.
Fat-dissolving injection with deoxycholic acid has a documented safety profile when performed by trained doctors, with side effects usually limited to temporary swelling, tenderness, and bruising. Proper mapping keeps the agent within the fat layer. Your doctor reviews your medical history and the treatment area to reduce risk before each session.
Common, expected effects include swelling, tenderness, redness, bruising, and temporary firmness or numbness in the treated area, which resolve over days to a couple of weeks. These are the early-phase changes you see before slimming. Broader contouring choices appear on our body rejuvenation page.
Aftercare is straightforward: apply a cold compress if advised, avoid intense heat and heavy exercise for a few days, and let the swelling settle naturally. Stay hydrated to support fat clearance, which helps the contour emerge. The clinic provides written aftercare so you can manage the area confidently between sessions.
A single session needs only 1 to 2 days, covering the consultation and the injection, though swelling follows afterwards, so the area will not photograph at its best yet. Because the full plan spans several sessions weeks apart, many international patients continue later. Our English team coordinates timing to fit your travel schedule.
Yes, flying after a fat-dissolving injection is generally fine, as it is non-surgical, though expect swelling during travel and a slimmer contour only weeks later. Stay hydrated and avoid excess heat. You can send photos for remote review in English so your slimcut injection progress is tracked from abroad.
