"Does fat-dissolving injection really work?" "How many sessions do I need?" "How is it different from GLP-1?" "I'm worried about downtime." This article answers all your questions about fat-dissolving injections.

Fat-dissolving injection (Kabelline) is a localized fat reduction treatment that directly injects into fat cells to dissolve and reduce them. Unlike "whole-body weight loss" with GLP-1, it allows you to slim down specific areas of concern, such as the abdomen, under the chin, and upper arms. Our clinic offers in-person treatments (in Aoyama, Tokyo).

  • Fat dissolving injection (Kabelline) is available for in-person treatment (Tokyo, Aoyama). From ¥18,800.
  • GLP-1 (Rybelsus, Mounjaro) is available for online prescriptions nationwide.
  • Please start by consulting with us.

1. What is Fat Dissolving Injection (Kabelline) and How it Works

Kabelline (deoxycholic acid) is a component of bile acid that destroys and dissolves fat cell membranes, leading to their reduction. The dissolved fat is metabolized and excreted from the body through the lymphatic and vascular systems. A key feature is that the number of fat cells is reduced, making it difficult to rebound.

Item Content
Active Ingredient Deoxycholic Acid (Kabelline)
Cost (Our Clinic) From ¥18,800 (varies by area and injection volume)
Treatment Time Approximately 15–30 minutes
Downtime Swelling and hardness may occur for several days after injection
Effect Perception Many people notice changes in 1–2 months
Rebound Difficult to rebound as the number of fat cells is reduced

2. Effects and Characteristics by Area

Area Effect Precautions
Abdomen (belly area) ◎ Most effective. For improving waistline Treatment primarily for areas with subcutaneous fat
Under Chin / Jawline ◎ Popular for smaller face and reducing chin sagging Swelling may be noticeable. Avoid 2 weeks before important events.
Thighs (inner/outer) ○ For volume reduction Often requires multiple treatments
Upper Arms ○ For improving "bat wing" fat Often requires multiple treatments
Back / Underarms ○ For areas of concern when wearing light clothing Approach varies depending on the area

3. How Many Sessions Are Needed? Recommended Schedule

Phase Interval Number of Sessions Notes
Initial Every 2–4 weeks 2–4 sessions Some may feel changes after 1 session, but multiple sessions are recommended for more definite results.
Maintenance/Additional As needed Depends on situation Additional treatments may be performed for maintenance after reaching the goal.

💡 "Will I be ready for summer?" Downtime subsides in 1-2 weeks after treatment, and changes are usually felt in 1-2 months. If you want to be ready for the height of summer in July, we recommend starting now.

4. Downtime and Precautions

  • Day of Treatment: Swelling, warmth, and redness may occur. Avoid strenuous exercise, bathing, and alcohol.
  • 1-3 Days After: Swelling and hardness may peak.
  • 1 Week After: Swelling usually subsides.
  • 1-2 Months After: Fat excretion progresses, and changes in silhouette are noticed.

⚠️ Downtime for facial treatments can be more noticeable. We recommend avoiding treatments within two weeks before important events (weddings, important meetings, etc.).

5. Differences from GLP-1 — Whole-Body vs. Localized Fat Reduction

Comparison Item Fat Dissolving Injection GLP-1 (Rybelsus, Mounjaro)
Weight Loss Method Fat reduction only in the injected area (localized fat reduction) Overall body weight reduction (whole-body weight loss)
How to Receive Requires clinic visit ✅ Online prescription, taken at home
Suitable for Those with average weight but concerns about specific areas Those who want to lose overall weight or struggle with appetite control
Estimated Cost From ¥18,800 (varies by area and number of sessions) Approximately ¥10,000–30,000 per month

If you wish to lose weight overall while also addressing specific areas, the most effective approach is a combination of GLP-1 (online prescription) and fat dissolving injections (in-person). Our clinic offers both.

6. Frequently Asked Questions

QWill I rebound after fat dissolving injections?
A

Since the number of fat cells is reduced, it is characterized by being less prone to rebound. However, remaining fat cells may enlarge, causing a return to the previous state. It is important to maintain good eating habits and exercise routines even after the treatment.

QCan I use GLP-1 at the same time?
A

Yes. It is possible to combine GLP-1 to lose overall weight with fat-dissolving injections for specific areas. Our clinic also offers plans where you can receive GLP-1 prescribed online and fat-dissolving injections in-person.

QIs it okay to receive treatment the day before work?
A

Swelling and hardness may persist for several days. Especially after facial treatments (under the chin), if your job involves being in public, we recommend scheduling with several days of leeway.
