Fat Dissolving & Body Contouring

Fat Dissolving & Body Contouring in Seoul

Doctor profile · Doctorpetit Clinic Hongdae, Seoul

Non-surgical body contouring in Seoul covers minimally invasive treatments that target stubborn, localized fat deposits and help refine the shape of the body without incisions. At Doctorpetit Clinic Hongdae, this category brings together fat-dissolving injections, the Body ONDA microwave treatment, carboxytherapy, and physician-supervised diet medication. Each approach works differently, so the right choice depends on the area, the type of concern, and whether the goal is local contour or overall weight management.

What Is Fat Dissolving & Body Contouring?

Fat Dissolving & Body Contouring is a group of minimally invasive treatments that act on localized fat deposits to refine and define body or facial contours, rather than to produce large-volume weight loss.

• Lipolytic injections deliver a solution into the fat layer that is intended to chemically break down fat-cell membranes in small, diet- and exercise-resistant areas.
• Body ONDA delivers microwave energy that heats the deeper fat layer while the skin surface is protected.
• Carboxytherapy injects medical-grade carbon dioxide (CO₂) into the fat layer, with the aim of increasing local circulation and oxygen supply.
• Diet medication works systemically, supporting appetite or metabolic regulation under a physician's supervision.
• None of these is a substitute for overall weight management, and the clinic frames the category around local contour improvement.

Treatments in this group fall into three broad families. Injectable approaches act chemically on fat in a precise spot. Energy-based treatment acts through controlled heat across a wider zone and also addresses cellulite and skin firmness. Medication acts on the whole body rather than on one area. Because a soft lower abdomen can reflect fat, loose skin, fluid retention, or general weight, the consultation begins by working out which of these is driving the shape you want to change.

Who Performs Fat Dissolving & Body Contouring at Doctorpetit Clinic Hongdae

Dr. Chae-ho Lee, Medical Director

Every patient in this category is examined by Dr. Chae-ho Lee, who heads the Hongdae branch as Medical Director and is its sole physician; he is the performing doctor for this specialty and writes any diet-medication prescription. He is a member of the Korean Obesity & Aesthetic Body Shaping society, the professional affiliation most closely tied to this field. 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. Botulinum toxin, fillers, skin boosters, and non-surgical lifting form the center of his wider practice, and he held director roles at two Seoul clinics before taking charge of the Hongdae branch. Because one doctor handles the assessment, the treatment, and the follow-up, you discuss your body goals with the same person who decides on the approach.

Fat Dissolving & Body Contouring Options Available

The clinic lists four services in this category. They differ in how they act, how long a visit takes, and what recovery looks like.

Service	How it works	Session time	Recovery	Results (individual variation applies)
Fat-Dissolving Injection / Lipolysis (V-Fit)	Injectable lipolytic solution placed in localized fat	About 5 minutes	Residual swelling about 1–2 days	Changes from about 3–7 days; maintenance about 1 month
Body ONDA	Microwave energy delivered to the subcutaneous fat layer	About 15–20 minutes	Daily activities resume immediately	Maintenance about 6 months
Carboxytherapy & Body Slimming	CO₂ gas injected into the fat layer	About 15–30 minutes	Gas or fullness sensation for several hours	Develops gradually over several weeks
Diet Medication Prescription	Prescription medication with diet, exercise, and monitoring	Visit about 15–30 minutes	No procedural recovery	Assessed over weeks to months

Fat-Dissolving Injection / Lipolysis

This service uses an injectable solution to break down accumulated fat in small, defined areas such as the chin, cheeks, upper arms, or abdomen. The clinic's own formulation is V-Fit, which Doctorpetit describes as a steroid-free fat-dissolving injection developed with its own technology and associated with relatively little pain and swelling. The clinic also describes V-Fit as stronger than conventional contour injections; that is the clinic's characterization rather than a comparison published in independent studies.

Each session takes about five minutes, and ice cooling is used for comfort. The clinic recommends a course of three or more sessions at one-week intervals rather than a single injection, and it notes that combining treatment with dieting can enhance the effect.

Under the same lipolysis heading, the clinic also lists Violette, a deoxycholic-acid-based fat-destroying injection. Numbing cream is applied beforehand and ice cooling follows. A session takes about 10–15 minutes, and two to three treatments at four-week intervals are typical, with up to six stated depending on fat volume. Swelling can last one to two weeks, and gradual reduction begins around two to four weeks. For context, deoxycholic acid is a cytolytic agent that destroys cell membranes when injected into tissue; in the United States one deoxycholic acid injection is approved only for fat below the chin, and its label states that use elsewhere on the body has not been established (FDA prescribing information).

Body ONDA

Body ONDA is a non-surgical treatment that uses microwave energy to target subcutaneous fat while also addressing cellulite and skin elasticity. It is intended for the abdomen, flanks, thighs, and upper arms. No separate anesthesia is required, a session takes about 15–20 minutes, and daily activities can resume straight away. The clinic states a maintenance period of about six months.

The ONDA Coolwaves platform, manufactured by DEKA in Italy, operates at 2.45 GHz and uses a deep handpiece and a shallow handpiece; an international advisory board has published recommendations on its use for cellulite and localized adiposity (Onda advisory board, PMC).

Carboxytherapy & Body Slimming

Carboxytherapy delivers CO₂ gas into the fat layer of a selected area, most often the abdomen, thighs, upper arms, or calves. The clinic describes the aim as promoting blood flow and oxygen supply to support fat breakdown, smoother-looking cellulite, firmer skin, and less swelling. A session usually takes 15–30 minutes, and several sessions may be suggested depending on the goal. A spreading-gas or full sensation near the injection points is expected and generally fades within a few hours.

Published evidence for this treatment is modest. A four-year audit from a single practice treated 101 women for abdominal fat with carbon dioxide therapy and reported only minor complications, such as injection-site pain, crepitus, and aches lasting under 30 minutes, plus needle-entry bruising that resolved within 7–10 days (Carboxytherapy audit, PMC).

Diet Medication Prescription

This service is individualized medication management for weight, not a cosmetic procedure. The prescription takes into account your constitution, lifestyle, weight goals, and any underlying medical conditions. Depending on the doctor's judgment, the clinic states that options may include appetite suppressants, fat-absorption inhibitors, or metabolism-promoting medications. The stated aim is broader than weight alone: body-fat management, healthier eating habits, and metabolic balance, supported by regular monitoring.

Prescription weight management is a category in which medication supports rather than replaces healthy eating and physical activity; the U.S. National Institute of Diabetes and Digestive and Kidney Diseases notes that these medications work best when combined with a lifestyle program (NIDDK). The same guidance advises against taking such medication only to improve appearance.

Who Is a Good Candidate for Fat Dissolving & Body Contouring?

The clinic designs these treatments for local contour concerns rather than as general weight-loss therapy. Suitability depends on the body area, fat distribution, skin condition, and goal.

Potential candidates include:

• Adults with small, localized pockets of fat that persist despite diet and exercise.
• Generally healthy adults who expect gradual, localized contour improvement rather than dramatic change.
• People concerned about the appearance of cellulite or reduced skin firmness alongside localized fat, for whom Body ONDA or carboxytherapy may fit.
• People who want a non-surgical option with little or no downtime.
• For diet medication, people who are overweight and already working on their weight through diet and exercise.

Treatment may be postponed or unsuitable for:

• People who are pregnant or breastfeeding.
• People with uncontrolled metabolic or cardiovascular disease.
• People with an active infection, inflammation, or significant skin problem at the treatment site.
• People with allergies to treatment ingredients.
• People with implanted electronic devices, in the case of Body ONDA.
• People with significant circulation problems, in the case of carboxytherapy.
• People expecting large-volume fat loss.
• People taking medications that could interact with the planned treatment.

Dr. Lee makes the final call on eligibility after reviewing your history.

What to Expect: Procedure, Recovery, and Results Timeline

Before treatment

• Disclose all medications, supplements, allergies, medical conditions, and previous procedures.
• For injection-based treatments, patients are typically asked to avoid alcohol and blood-thinning medication beforehand, but only after discussing any prescribed medicine with the prescribing doctor.
• For Body ONDA, keep the skin clean and free of lotions on the day, and avoid sun exposure, tanning, and irritating products in the days before.
• For carboxytherapy, wear loose clothing and avoid strenuous exercise immediately beforehand.
• For diet medication, be ready to discuss your health, lifestyle, and goals, and do not start, stop, or change any weight-loss medication without medical guidance.

The injection procedure, step by step

1. Consultation: Dr. Lee examines the target areas and discusses your contour goals.
2. Preparation: the area is cleansed and marked.
3. Comfort: ice cooling is applied.
4. Injection: the fat-dissolving solution is placed into the marked areas.
5. Aftercare: you receive simple instructions, including light massage of the area on the same day.

The clinic decides the treatment interval after visually assessing laxity and fat accumulation.

Timeline

Time after treatment	What usually happens
Same day	Body ONDA patients return to normal activity. Carboxytherapy gas sensation fades over several hours. Light showering is allowed after carboxytherapy.
Days 1–2	Residual swelling after a fat-dissolving injection usually settles.
Days 3–7	Changes from fat-dissolving injections begin to appear.
Weeks 1–3	Repeat fat-dissolving sessions continue at one-week intervals. Violette swelling may persist for up to two weeks.
Weeks 2–4	Violette begins producing gradual reduction. Changes after ONDA sessions typically start to appear within a few weeks.
About 1 month	Stated maintenance period for the fat-dissolving injection.
About 6 months	Stated maintenance period for Body ONDA.

Aftercare

After a fat-dissolving injection, lightly massage the area on the day of treatment. After Violette, use cold compresses for about three days, then switch to warm compresses. After carboxytherapy, avoid saunas, jjimjilbang, and strenuous exercise; circulation and drainage can be slower in some people. After Body ONDA, keep the area clean and hydrated and avoid excessive heat and strenuous activity for the period your doctor advises. Diet medication requires regular monitoring and continued lifestyle changes rather than a one-time visit.

Combining Fat Dissolving & Body Contouring with Other Treatments

Any pairing is decided after assessment.

• Diet and exercise — the clinic states that fat-dissolving injections can deliver greater effects when combined with dieting.
• Within this category — carboxytherapy may be combined with Body ONDA or fat-dissolving injections when both fat and skin texture are concerns.
• Botox Treatments — the clinic lists Botox among carboxytherapy combination options, since muscle relaxation and fat-layer treatment act on different tissues.
• Non-Surgical Lifting — InMode FX pairs fat reduction with lifting, and FORMA focuses on collagen tightening, for patients whose concern includes skin laxity.

Combining procedures in one visit should always be confirmed with the treating doctor.

Safety, Precision, and Clinic Standards

• Since January 2023, the Ministry of Health and Welfare has listed Doctorpetit Clinic Hongdae as a registered institution for attracting foreign patients.
• That status is granted under the Medical Overseas Expansion and Foreign Patients Attraction Act.
• Business registration: 250-54-00398.
• By the clinic's own statement, products are certified genuine and given at the indicated dosage.
• Every plan begins with a 1:1 consultation that considers skin condition and elasticity.
• Body ONDA protects the skin surface while delivering heat to the deeper fat layer.

Known risks

Fat-dissolving injections commonly cause temporary swelling, tenderness, and discomfort; Violette swelling can last one to two weeks. Injectable deoxycholic acid carries label warnings for nerve injury near the jaw, difficulty swallowing, bruising, and skin ulceration when used under the chin (FDA prescribing information). Body ONDA can cause temporary redness, warmth, swelling, tenderness, or bruising. Rarely, Body ONDA may cause burns, altered skin sensation, or uneven results. Carboxytherapy can cause redness, bruising, a pressure or burning sensation, or less commonly infection or prolonged swelling.

Diet medication can cause dry mouth, headache, and insomnia, which the clinic lists as common side effects. Relying on medication alone can lead to side effects and weight regain. Weight-management medications should not be taken during pregnancy or when planning pregnancy, and some weight returns after stopping is likely, according to the NIDDK.

The Bottom Line

• Fat Dissolving & Body Contouring targets localized fat and body shape; it is not a replacement for overall weight management.
• Doctorpetit Clinic Hongdae offers four options: V-Fit fat-dissolving injections, Body ONDA, carboxytherapy, and diet medication prescription.
• Dr. Chae-ho Lee, the clinic's only physician, assesses every patient and leads every treatment.
• Recovery is short for most options, from immediate return after Body ONDA to about one to two days of swelling after injections.
• Results build over a course of sessions and are maintained best with consistent diet and exercise.

Frequently Asked Questions

Will fat-dissolving injections help me lose weight overall?
No. Fat-dissolving injections are meant for small, localized areas such as the chin, arms, or abdomen, not for reducing overall body weight. If general weight is the main concern, the diet medication service, combined with diet and exercise, is the more relevant conversation.

What makes V-Fit different from other fat-dissolving injections?
Doctorpetit describes V-Fit as its own steroid-free formulation with relatively little pain and swelling. The clinic also describes it as stronger than conventional contour injections. Ask Dr. Lee during your consultation how it suits the specific area you want to treat.

How many sessions will I need?
For the fat-dissolving injection, the clinic recommends three or more sessions at one-week intervals. Violette typically needs two to three treatments four weeks apart. Carboxytherapy may require several sessions, depending on the goal.

Does Body ONDA hurt?
No separate anesthesia is needed. Most people feel warmth during treatment, and the level of discomfort varies with the individual and the settings used.

Can I fly home soon after treatment?
Body ONDA lets you return to daily activities immediately, though waiting 24–48 hours before a long flight may be reasonable if redness or swelling is present. Fat-dissolving injection swelling usually settles in one to two days. Confirm flight timing with the clinic based on your plan.

What are the side effects of diet medication?
The clinic lists dry mouth, headache, and insomnia as common side effects. Risks vary with the medication chosen and your health, and relying only on medication can lead to weight regain.

Can I combine several body treatments in one trip?
Some combinations, such as carboxytherapy with Body ONDA or fat-dissolving injections, may be suitable. Dr. Lee decides what to combine and in what order after examining you.
