Hongdae Fat Dissolving Injection: How to manage localized fat that doesn't go away even with exercise

July 30, 2026

Hello.

I am Dr. Kim Dong-young, Director of Cleor Clinic Hongdae Branch.

You have probably felt that even after managing your weight to some extent, fat in specific areas like your belly, the back of your arms, or the inner thighs just won't go away, and no matter how much you exercise, the lines don't seem to smooth out, right?

"I've been exercising and managing my diet consistently for a year, but my lower belly and the back of my arms remain the same.

Liposuction feels like too much, and I want to know if there are any methods for localized management.

There are so many types of fat-dissolving injections that I'm confused about which one is right for me."

These are categories of inquiries I frequently encounter in the consultation room.

Localized fat requires a different approach than overall weight loss.

Since the order in which our bodies lose fat is determined by genetics and hormones, areas that remain until the very end (such as the abdomen, arms, thighs, calves, etc.) are known as categories that are not easily addressed even with overall dieting.

The Hongdae fat-dissolving injection is a way to approach such localized fat.

Today, I will explain the principles of how fat-dissolving injections work, how the Barbie Fit and Fat-Free lines differ, and how they can be combined with medication prescriptions.

What is the Hongdae fat-dissolving injection?

👉 The Hongdae fat-dissolving injection is a localized fat management procedure that involves injecting fat-dissolving ingredients directly into the fat layer of the desired area to break down fat cells and excrete them as waste. It is a category that approaches comprehensive management by combining three lines: Barbie Fit (an option containing steroids), Fat-Free (a non-steroid option), and diet medication prescriptions.

Fat-dissolving injections work by injecting ingredients that destroy fat cell membranes into the subcutaneous fat layer of the desired area.

It is a category known for the principle that once the injected ingredients emulsify and break down the fat cell membranes, the fat inside is released out of the tissue and gradually excreted through waste pathways such as sweat and urine.

Unlike liposuction, which physically removes fat cells themselves, it is a method that reduces the volume of fat cells, so the burden is relatively low.

It is known as a category frequently considered for localized management because it is performed without incisions or general anesthesia and allows for an easy return to daily life after the procedure.

How fat-dissolving injections work

👉 Fat-dissolving injections are procedures that reduce localized fat in four steps: ingredient injection, fat cell membrane destruction, fat release and waste excretion, and area line refinement.

Ingredient injection

This method involves injecting small amounts of fat-dissolving ingredients into the subcutaneous fat layer of the desired area.

The ingredients mainly used are PPC (phosphatidylcholine), which emulsifies fat cell membranes, and DCA (deoxycholic acid), which destroys fat cells, and depending on the option, it is a category where steroids or side-effect-reducing ingredients are also blended.

Fat cell membrane destruction

The injected ingredients act on the fat cell membranes, going through a process where the membranes are emulsified and destroyed.

When the cell membrane collapses, the fat inside is released out of the tissue, which is a line that proceeds by reducing the volume of the fat cells themselves.

Fat release and waste excretion

The fat released outside the cells is absorbed into the body's metabolic process and gradually excreted through waste pathways such as sweat and urine.

Since this excretion process takes time, it is a category where line changes appear gradually over 1 to 2 weeks rather than immediately after the procedure.

Area line refinement

As the volume of fat cells decreases, the size of the area decreases and the lines are refined.

It is a line reported to focus more on localized line improvement of the treated area rather than overall weight change.

Differences between Barbie Fit and Fat-Free

👉 The body fat-dissolving injections at the Hongdae branch are divided into two lines: Barbie Fit, which contains steroids, and Fat-Free, which is steroid-free, and they differ in ingredient characteristics and usage purposes.

Barbie Fit - Contains steroids

  • Barbie Fit is a line where a small amount of steroid is blended with fat-dissolving ingredients.

As steroids are included, inflammation and swelling in the treated area are alleviated, and it is an option that focuses on improving surface irregularities like cellulite, making it a category that can be approached without burden for areas such as the back of the neck, knees, calves, upper arms, thighs, and abdomen.

The price range is relatively affordable, making it a good line to approach by area.

Fat-Free - Non-steroid

Fat-Free is a line formulated mainly with fat-dissolving ingredients without steroid components.

  • Since there are no steroids, the burden related to hormones during repeated procedures is relatively low, so it is a category referred to by those who continue regular management.

The dosage options are also diverse, ranging from 20cc, 60cc, 80cc, 100cc, 120cc, to 150cc, making it a line that can be finely adjusted according to the area range.

Selection criteria

Barbie Fit is usually referred to for effortless localized approaches or when cellulite is present, while Fat-Free is a category referred to if you have plans for repeated procedures or want a steroid-free line.

  • Options suitable for your management plan and area characteristics are reviewed together during the pre-procedure consultation.

Combining fat-dissolving injections + diet medication prescriptions

👉 At the Hongdae branch, an option to combine fat-dissolving injections with diet medication prescriptions is available, making it a line where you can manage both localized areas and your overall condition.

Since fat-dissolving injections are a way to approach localized fat, there is a limit to their purpose for overall weight loss.

Diet medication is a line prescribed according to individual condition and constitution, so it is a category where combination is considered if you want to manage your overall condition along with fat-dissolving injections.

  • Prescriptions are made according to your constitution and condition under the guidance of medical staff, so consultation is conducted together according to your management plan.

Hongdae fat-dissolving injection lineup

👉 The Hongdae branch operates fat-dissolving injections in three lines: Barbie Fit (contains steroids), Fat-Free (non-steroid), and diet medication prescriptions, and it is a configuration where you can select options according to the area and dosage.

Barbie Fit line (contains steroids)

Fat-Free line (non-steroid)

Diet medication prescription line

Generally, stable results are reported when fat-dissolving injections are performed 3 to 4 times at 2-week intervals.

  • It is known as a category where line changes begin to be felt from 1 to 2 weeks after the procedure, and results become established as the number of sessions accumulates.

Options suitable for your area, fat thickness, and management plan are reviewed together during the pre-procedure consultation.

Who is the fat-dissolving injection suitable for?

Those who have managed their overall weight but cannot lose fat in specific areas

Those concerned about lines in areas such as the abdomen, arms, thighs, and calves

Those who find liposuction burdensome and want to approach it in a non-surgical way

  • Those who have cellulite and want to smooth out surface irregularities

Those who want to manage localized areas and overall diet together

Side effects and things to know in advance about Hongdae fat-dissolving injections

👉 Although the Hongdae fat-dissolving injection is a procedure line with long-standing clinical data, it is good to understand in advance that it is a category where result stability varies depending on ingredient characteristics, the treated area, and individual fat thickness and elasticity.

Immediately after the procedure, light redness, micro-swelling, thin bruising, temporary pain, and heat may appear in the treated area.

It is generally reported to resolve naturally within a few days to a maximum of 1 to 2 weeks.

Hard nodules (lumps) may settle in the fat layer of the treated area for a few days, and since it is a category where surface unevenness may be felt briefly, it is a line where it is good for recovery stability to refrain from massage for a few days after the procedure.

  • Since steroid-containing lines like Barbie Fit can affect hormonal balance during repeated procedures, regular use requires caution, so it is a category where the interval between sessions is adjusted according to medical staff guidance when repeating procedures on the same area.

If there is a large amount of fat, it may be difficult to approach with fat-dissolving injections alone.

In this case, it is a line where liposuction or other methods may be considered together, so the direction suitable for your fat thickness is organized together during the pre-procedure consultation.

It is important to ensure stability by proceeding with the appropriate dosage and method after checking your area, fat thickness, and elasticity status during the pre-procedure consultation under the guidance of experienced medical staff.

If any of the following apply to you, please inform us during the consultation as the procedure may be restricted or require prior confirmation.

If you are pregnant or breastfeeding

If you have a history of allergies to ingredients

If there is an active infection or inflammation in the area to be treated

If you have been diagnosed with autoimmune diseases, diabetes, or thyroid diseases

If you are regularly taking anticoagulants/antiplatelet agents or have a bleeding tendency

If you have hormone-related diseases or are taking related medications

⚠️ Precautions before and after fat-dissolving injection procedure

👉 Fat-dissolving injection is a procedure where recovery speed and result stability vary depending on pre-procedure condition management and post-procedure waste excretion management.

❓ Frequently Asked Questions (FAQ)

Q. When can I see the results of the Hongdae fat-dissolving injection?

You will start to feel line changes from about 1 to 2 weeks after the procedure.

It is known as a category where stable results are established when performed 3 to 4 times at 2-week intervals rather than expecting big changes from a single procedure.

  • Q. Should I choose Barbie Fit or Fat-Free?

  • It depends on the management purpose and repetition plan.

  • Barbie Fit is for effortless localized approaches or cellulite improvement, while Fat-Free is a category referred to if you have plans for repeated procedures or want a steroid-free line, so we will organize it together during the pre-procedure consultation.

Q. How are fat-dissolving injections different from liposuction?

The approach and fat disposal method are different.

Liposuction is a surgical method that physically removes fat cells themselves, while fat-dissolving injections are a non-surgical method that reduces fat cell volume, so fat-dissolving injections are a line referred to if you want an effortless approach without a large amount of fat.

Q. How many sessions of Hongdae fat-dissolving injections should I receive?

Stable results are generally reported when performed 3 to 4 times at 2-week intervals.

It is a category where the session plan is decided according to your condition during the pre-procedure consultation as the session plan is adjusted according to fat thickness or area range.

Q. How much pain is there with fat-dissolving injections?

  • Since it is a method performed after applying anesthetic cream before the procedure, strong pain is not significant.

  • You may feel a brief stinging and heat during the procedure, and it is a category where there may be tenderness and soreness for a few days after the procedure.

  • Q. Can I gain weight again after the procedure?

  • Since fat-dissolving injections are a method of reducing fat cell volume, there is a possibility that remaining fat cells may grow again if you do not manage them.

  • It is a category where managing your diet and exercise after the procedure helps maintain the results.

Q. Do I have to receive diet medication prescriptions together?

Combination is not mandatory.

It is a category possible with only fat-dissolving injections if you only want localized area management, and it is a line where combination is considered if you want to manage your overall condition together.

Localized fat is a category that is not easily resolved even with overall weight loss, so it is a direction for area management that requires a localized approach.

Unlike surgical methods that remove fat cells themselves like liposuction, it is the reason why options that can be approached without burden as a non-surgical method that reduces fat cell volume are needed.

The Hongdae fat-dissolving injection is a localized fat management procedure that breaks down fat cells and excretes them as waste by injecting fat-dissolving ingredients directly into the fat layer of the desired area.

At the Hongdae branch, we operate various lines for body line management in addition to fat-dissolving injections.

The Barbie Fit line, which allows for effortless localized approaches with steroids, the Fat-Free line, which is referred to from the perspective of repeated procedure safety without steroids, and diet medication prescriptions that are combined when overall condition management is needed, are categories where you can choose combinations according to your management plan.

The direction suitable for your area and management plan will be confirmed directly during the consultation.

👉 지방분해주사는 시술 전 컨디션 관리와 시술 후 노폐물 배출 관리에 따라 회복 속도와 결과 안정성이 달라지는 시술입니다.

❓ 자주 묻는 질문 (FAQ)

Q. 홍대 지방분해주사 결과는 언제부터 확인할 수 있나요?

시술 후 1~2주 정도부터 라인 변화가 체감되기 시작해요.

한 번의 시술로 큰 변화를 기대하기보다는 2주 간격으로 3~4회 진행할 때

안정적인 결과가 자리 잡는 카테고리로 알려져 있습니다.

Q. 바비핏과 팻프리 중 어떤 걸 골라야 하나요?

관리 목적과 반복 계획에 따라 다른 편이에요.

Q. 지방분해주사와 지방흡입은 어떻게 다른가요?

접근 방식과 지방 처리 방식이 다른 편이에요.

지방흡입은 지방 세포 자체를 물리적으로 제거하는 수술 방식이고,

지방분해주사는 지방 세포 부피를 줄이는 비수술 방식이라

지방량이 크지 않으면서 부담 없는 접근을 원하시는 경우 지방분해주사가 참고되는 라인입니다.

Q. 홍대 지방분해주사는 몇 회를 받아야 하나요?

2주 간격으로 3~4회 진행할 때 안정적인 결과가 보고되는 편이에요.

지방 두께나 부위 범위에 따라 회차 계획이 조정되는 편이라

사전 진료에서 본인 상태에 맞는 회차가 결정되는 카테고리입니다.

시술 후 며칠간 압통과 뻐근함이 있을 수 있는 카테고리입니다.

Q. 시술 후 살이 다시 찔 수 있나요?

지방분해주사는 지방 세포 부피를 줄이는 방식이라

관리를 하지 않으면 남아 있는 지방 세포가 다시 커질 가능성이 있는 편이에요.

시술 후 식단과 운동 관리를 함께 가져가시는 것이

결과 유지에 도움이 되는 카테고리입니다.

Q. 다이어트 약 처방은 꼭 함께 받아야 하나요?

병행이 필수는 아니에요.

국소 부위 관리만 원하시면 지방분해주사만으로도 가능한 카테고리이고,

전체 컨디션 관리를 함께 가져가고 싶으신 경우 병행이 검토되는 라인입니다.

부위별 지방은 전체 체중 감량으로도 잘 정리되지 않는 카테고리라

국소적인 접근이 필요한 부위 관리 방향입니다.

지방흡입처럼 지방 세포 자체를 제거하는 수술 방식과 달리,

지방 세포 부피를 줄이는 비수술 방식으로

부담 없이 접근할 수 있는 옵션이 필요한 이유예요.

홍대 지방분해주사는 원하는 부위 지방층에 지방 분해 성분을 직접 주입해

지방 세포를 분해하고 노폐물로 배출시키는 국소 지방 관리 시술이에요.
