Does Fat-Dissolving Injection (Cabelline) Really Work? A Doctor Explains Its Effects by Area, Downtime, and Differences from GLP-1
A doctor explains how to use it with GLP-1
"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 if you're considering fat-dissolving injections.
Fat-dissolving injection (Cabelline) is a localized fat reduction treatment that directly injects into fat cells to dissolve and reduce them. Unlike GLP-1, which provides "overall weight loss," it can specifically slim down troublesome areas like the abdomen, chin, and upper arms. Our clinic offers in-person treatments (Tokyo, Aoyama).
- Fat-dissolving injections (Cabelline) are available for in-person treatment (Tokyo, Aoyama). From ¥18,800.
- GLP-1 (Rybelsus, Mounjaro) is also available for online prescription nationwide.
- Please start with a consultation.
1. What is fat-dissolving injection (Cabelline) and how does it work?
Cabelline (deoxycholic acid) is a bile acid component that destroys and dissolves fat cell membranes, reducing fat cells. The dissolved fat is metabolized and excreted from the body through the lymphatic vessels and blood vessels. It is characterized by being less prone to rebound because the number of fat cells is reduced.
| Item | Content |
|---|---|
| Active ingredient | Deoxycholic acid (Cabelline) |
| 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 |
| Perception of effects | Many people feel changes in 1-2 months |
| Rebound | Less prone to rebound as the number of fat cells decreases |
2. Effects and characteristics by area
| Area | Effect | Notes |
|---|---|---|
| Abdomen (belly area) | ◎ Most effective. For improving waistline. | Treatment is primarily for areas with a lot of subcutaneous fat. |
| Under chin/jawline | ◎ Popular for smaller face and improving sagging under the chin. | Swelling tends to be noticeable. Avoid two 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/sides | ○ For areas of concern when wearing light clothing. | Approach varies by area. |
3. How many sessions do I need? Recommended schedule
| Phase | Interval | Number of sessions | Notes |
|---|---|---|---|
| First session onwards | Every 2-4 weeks | 2-4 sessions | While some may feel changes after one session, 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 it be ready for summer?" Downtime subsides in 1-2 weeks after treatment, and changes are felt in 1-2 months. If you want to be ready for the peak summer in July, we recommend starting now.
4. Downtime and precautions
- Day of: Swelling, warmth, and redness may occur. Avoid strenuous exercise, bathing, and alcohol.
- 1-3 days after: Swelling and hardness may peak.
- 1 week after: In most cases, swelling subsides.
- 1-2 months after: Fat excretion progresses, and changes in silhouette are felt.
⚠️ Downtime can be more noticeable for facial treatments. We recommend avoiding treatments two weeks before important events (weddings, important meetings, etc.).
5. Difference from GLP-1—overall weight loss 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 (overall weight loss) |
| How to Receive | Requires clinic visit | ✅ Online prescription, taken at home |
| Who it's for | Those with normal weight but concerned about specific areas | Those who want to lose weight overall or have difficulty controlling appetite |
| Estimated Cost | From ¥18,800 (varies by area and number of sessions) | Approximately ¥10,000-¥30,000 per month |
If you want to lose weight overall while also addressing specific areas, a combination of GLP-1 (online prescription) + fat-dissolving injections (in-person) is the most effective. Our clinic offers both.
6. Frequently Asked Questions
Since the number of fat cells decreases, it is less prone to rebound. However, it may return if the remaining fat cells enlarge. Maintaining eating habits and exercise after treatment is important.
Yes. It is possible to combine GLP-1 for overall weight loss with fat-dissolving injections for specific areas. Our clinic offers plans that allow you to receive GLP-1 prescriptions online while getting fat-dissolving injections in person.
Swelling and hardness may persist for several days. Especially after facial treatments (under the chin), if your job requires you to meet people, we recommend scheduling with a few days of leeway.
