Fat-Dissolving Injection / Lipolysis in Seoul

Doctor profile · Doctorpetit Clinic Hongdae, Seoul
A fat-dissolving injection in Seoul is a non-surgical treatment in which a lipolytic solution is injected into a small, localized pocket of fat to break down fat-cell membranes and refine the contour of that area. At Doctorpetit Clinic Hongdae, two injections sit under this heading: V-Fit, the clinic's own steroid-free formulation, and Violette, a deoxycholic-acid-based injection. Both target localized fat rather than overall weight; the clinic lists areas such as the chin, cheeks, upper arms, or abdomen for V-Fit.
What Is Fat-Dissolving Injection / Lipolysis?
Fat-dissolving injection, also called injection lipolysis, is the placement of a lipolytic solution into subcutaneous fat so that it chemically breaks down fat-cell membranes in small, diet- and exercise-resistant areas, gradually reducing the size of the treated area.
- Chemical, not mechanical. The solution acts on fat-cell membranes; there is no incision, suction, or device involved.
- Small, defined targets. It is used for localized deposits, such as under the chin, on the cheeks, on the upper arms, or on the abdomen.
- Contour, not weight. The intended result is a smaller, better-defined area, not a lower number on the scale.
- Gradual change. The body clears the treated fat over time, so the change appears over days to weeks rather than immediately.
- A course, not a one-off. Repeat sessions are recommended because each treatment adds to the previous one.
Why people choose an injection over surgery
Some U.S. patients look for fat-dissolving injections because they want to treat a small area of unwanted fat without an operation, and with far less downtime than surgical fat removal. A session is brief, there is no general anesthesia, and most people continue their day. The trade-off is scale: injections are designed for small areas, so they are not an alternative to liposuction for large volumes, nor a replacement for diet and exercise.
Who Performs Fat-Dissolving Injection at Doctorpetit Clinic Hongdae

Dr. Chae-ho Lee
Medical Director at Doctorpetit Clinic Hongdae
Dr. Chae-ho Lee gives every fat-dissolving injection at Doctorpetit Clinic Hongdae; he is its Medical Director and works as the sole physician. This treatment area is offered as a clinic service led by the Medical Director rather than as one of Dr. Lee's stated core specializations. His professional memberships include Korean Obesity & Aesthetic Body Shaping. At the consultation he assesses the area, skin condition, and elasticity, chooses between V-Fit and Violette, and sets the treatment interval after visually checking laxity and fat accumulation.
Fat-Dissolving Injection Options Available
The clinic lists two injections under its lipolysis menu. They differ in ingredient, session length, swelling, and how quickly results appear.
| Feature | V-Fit | Violette |
|---|---|---|
| What it is | The clinic's own steroid-free fat-dissolving injection | Deoxycholic-acid-based fat-destroying injection |
| Comfort measures | Ice cooling during treatment | Numbing cream before; ice cooling afterward |
| Session time | About 5 minutes | About 10–15 minutes |
| Swelling | Residual swelling about 1–2 days | Swelling may continue 1–2 weeks |
| When change appears | About 3–7 days | Gradual reduction from about 2–4 weeks |
| Recommended course | 3 or more sessions at 1-week intervals | Typically 2–3 sessions at 4-week intervals; up to 6 stated |
| Stated maintenance | About 1 month | About 3–6 months |
Individual variation applies to every figure in this table.
V-Fit
V-Fit is the injection Doctorpetit describes as its own special technology. The clinic states that it is steroid-free, that it causes relatively little pain and swelling, and that it has stronger effects than conventional contour injections; that last point is the clinic's own characterization rather than a result from a published head-to-head study. A V-Fit session takes about five minutes, and ice cooling is used to keep it comfortable. Rather than a single treatment, the clinic recommends three or more sessions one week apart, and it notes that combining the course with dieting can increase the effect.
Violette
Violette is a deoxycholic-acid-based injection. Numbing cream is applied before treatment and ice cooling is used immediately afterward. A session takes about 10 to 15 minutes, and two to three treatments at four-week intervals are typical, depending on fat volume, with up to six stated. Swelling can persist for one to two weeks, so Violette needs more recovery time than V-Fit, but the clinic states a longer maintenance period of about three to six months.
Deoxycholic acid as an ingredient has been studied mainly for fat under the chin. In the United States, the prescribing information for deoxycholic acid injection describes it as a cytolytic drug that destroys cell membranes when injected into tissue, indicates it only for moderate to severe submental fat, and states that safe and effective use outside the submental area has not been established (FDA prescribing information). A 2023 systematic review and meta-analysis of randomized trials found deoxycholic acid effective for submental fat reduction with generally well-tolerated side effects, while noting that all the eligible trials carried a potential risk of industry-sponsorship bias (Deoxycholic acid meta-analysis, PMC).
Who Is a Good Candidate for Fat-Dissolving Injection?
Fat-dissolving injections are intended for local contour concerns, not general weight loss. You may be a candidate if you are:
- An adult with small, localized areas of excess fat, such as under the chin or on the arms or abdomen.
- Generally healthy, with fat that has not responded to diet and exercise.
- Looking for a non-surgical approach with little downtime.
- Expecting gradual, localized improvement rather than dramatic change.
- Willing to complete a course of sessions and support it with healthy eating.
Treatment may need medical review, postponement, or another approach if you:
- Are pregnant or breastfeeding.
- Have an active infection or skin disease at the injection site.
- Have an allergy to any ingredient in the solution.
- Have certain medical conditions identified at consultation.
- Hope to achieve large-volume fat loss or overall weight reduction.
Suitability also depends on the treatment area and the amount of fat, which is why the decision is made in person.
How the consultation shapes the plan
The clinic offers a 1:1 customized consultation that takes individual skin condition and elasticity into account. That matters for lipolysis: if the skin over an area is lax, removing fat may not give the shape you hope for, and a different treatment or a combination may be suggested. Expect to discuss medications, allergies, medical conditions, and previous procedures, and to agree on which injection and how many sessions fit both your goal and your time in Seoul.
What to Expect: Procedure, Recovery, and Results Timeline

Before treatment
Tell the doctor about all medications, supplements, allergies, medical conditions, and previous procedures. Patients are typically asked to avoid alcohol and blood-thinning medication before injection-based treatments, but stop a prescribed medicine only if the prescribing doctor agrees. Ask the clinic for any treatment-specific instructions before your visit.
The session, step by step
- Consultation. Dr. Lee examines the target area and confirms the injection and plan.
- Preparation. The area is cleansed and marked.
- Comfort. Ice cooling is applied; for Violette, numbing cream is used beforehand.
- Injection. The fat-dissolving solution is injected into the marked area.
- Aftercare. You receive instructions before leaving, including light massage after V-Fit.
Recovery and results timeline (V-Fit)
| When | What to expect |
|---|---|
| Same day | Daily routine can continue; lightly massage the injection area. |
| Days 1–2 | Residual swelling generally settles. |
| Days 3–7 | Changes in the treated area gradually begin to appear. |
| Weeks 1–3 | Further sessions at one-week intervals build the effect. |
| About 1 month | Stated maintenance period, with individual variation. |
With Violette, plan for swelling of one to two weeks, use cold compresses for about three days and then switch to warm compresses, and expect gradual reduction to begin around two to four weeks after treatment.
Aftercare
After V-Fit, the clinic specifically recommends lightly massaging the injection area on the day of treatment. After Violette, follow the cold-then-warm compress routine. In both cases, follow the clinic's general post-treatment precautions, and contact the clinic if swelling, pain, or redness worsens instead of improving.
Planning a trip
A fat-dissolving injection is an outpatient treatment, and a stay of one to two days in Korea may be enough for a single session. The recommended courses change that: three or more V-Fit sessions a week apart, or Violette sessions four weeks apart, mean a longer stay or repeat visits. Flight timing should be confirmed with the clinic based on the area, the number of injections, and how you respond, and Violette's longer swelling is worth factoring in.
Combining Fat-Dissolving Injection with Other Treatments
The clinic states one combination directly: greater effects can be expected when the fat-dissolving injection is combined with dieting.
Within the same specialty, the clinic separately offers Body ONDA, Carboxytherapy & Body Slimming, and Diet Medication Prescription. Body ONDA uses microwave energy for subcutaneous fat, cellulite, and elasticity, whereas the fat-dissolving injection is an injectable treatment. Whether any of these belong in your plan alongside an injection is decided after assessment.
Safety, Precision, and Clinic Standards
- The Ministry of Health and Welfare has recognized Doctorpetit Clinic Hongdae as a foreign-patient medical institution since January 2023.
- Dr. Chae-ho Lee examines each patient and gives each injection himself.
- V-Fit is described by the clinic as steroid-free, and ice cooling is used to reduce discomfort.
- The clinic states that it uses certified genuine products according to the indicated dosage.
Possible side effects and risks
After V-Fit, the clinic describes relatively little pain and swelling, with residual swelling usually settling in one to two days. Temporary redness, bruising, tenderness, or mild discomfort around the treated area can also occur. Violette may involve pain and swelling lasting one to two weeks. Little pain does not mean complications are impossible; confirm the full risk profile and contraindications with the doctor.
For deoxycholic acid as a category, the U.S. prescribing information warns of nerve injury near the jaw, difficulty swallowing, injection-site bruising, and skin ulceration or tissue damage, particularly when the injection is placed incorrectly (FDA prescribing information). Seek medical attention for an uneven smile, trouble swallowing, or skin that darkens or breaks down after treatment.
The Bottom Line
- Fat-dissolving injections break down fat-cell membranes in small, localized areas to refine contour.
- The clinic offers V-Fit, its steroid-free formulation, and Violette, a deoxycholic-acid-based injection.
- V-Fit takes about five minutes, swelling settles in one to two days, and change begins around three to seven days.
- Violette involves longer swelling but a stated maintenance of about three to six months.
- Results depend on a course of sessions and are supported by healthy eating.
Frequently Asked Questions
Will a fat-dissolving injection help me lose weight?
No. It is meant for small, localized fat and for contour, not for overall weight. People concerned about general weight should discuss other options, such as the clinic's diet medication service.
What is the difference between V-Fit and Violette?
V-Fit is the clinic's own steroid-free injection, with short sessions and one to two days of swelling. Violette is deoxycholic-acid-based, takes a little longer per session, causes swelling for up to two weeks, and has a longer stated maintenance period. Dr. Lee recommends one after examining you.
Does it hurt?
The clinic describes V-Fit as having relatively little pain, and ice cooling is used during treatment. Violette uses numbing cream beforehand and ice cooling afterward.
How many sessions will I need?
For V-Fit, the clinic recommends three or more sessions at one-week intervals. Violette is typically two to three sessions four weeks apart, with up to six stated depending on fat volume.
When will I see results?
V-Fit changes gradually appear about three to seven days after treatment. Violette produces gradual reduction starting around two to four weeks.
How long do results last?
The clinic states a maintenance period of about one month for V-Fit and about three to six months for Violette, with individual variation. Diet and lifestyle strongly influence how long the change holds.
Can I fly home soon after treatment?
Many people can travel within a day or two after V-Fit, once swelling has settled. Confirm timing with the clinic, especially after Violette or when several areas are treated.
