What Is Mesoline Slim? A Fat-Dissolving Injection Containing Fat-Breaking Ingredients

Mesoline Slim is a type of fat-dissolving injection used as a body-slimming treatment.
Its two main active ingredients are:
- Phosphatidylcholine
- Sodium Deoxycholate
Phosphatidylcholine is a type of amino acid also used in the treatment of hyperlipidemia. It works to break down fat and help the body eliminate it as waste.
Sodium deoxycholate is a bile acid found naturally in human bile, known for its ability to emulsify fat.
What Are Fat-Dissolving Injections? A Body-Slimming Treatment That Reduces Fat in Targeted Areas
Fat-dissolving injections are a body-slimming treatment designed to break down and dissolve fat.
By injecting the solution into the subcutaneous tissue of targeted areas, the treatment may efficiently promote fat breakdown in those locations. Unlike some other slimming treatments, a key feature is the ability to address specific areas of concern.
Fat that is broken down by the injection enters the bloodstream and is eliminated from the body along with metabolic waste—allowing for fat reduction without surgery.
There are several types of fat-dissolving injections available, and the side effects and suitable treatment areas vary depending on the ingredients used.

Who May Benefit from the Mesoline Slim “Diet Injection”?
Mesoline Slim may be a suitable option for the following individuals:
- Those looking to reduce fat in specific areas (such as the upper arms or calves)
- Those who prefer to avoid surgical procedures such as liposuction
- Those who do not have the time to rest during a longer recovery period
- Those who have not noticed satisfactory results from slimming salon treatments
- Those who have experienced rebound weight gain after dieting
Mesoline Slim is characterized by its ability to target localized fat reduction with a relatively short downtime.
It may also support a body composition that is less prone to rebound weight gain, making it worth considering for those who have found it difficult to maintain results from dieting alone.
What Results Can Mesoline Slim Offer? Targeting Localized Fat That Is Difficult to Address Through Diet Alone

Mesoline Slim may offer localized fat reduction that is difficult to achieve through diet alone.
When dieting, it can be challenging to slim down a specific area without a carefully designed exercise program. Furthermore, some areas of the body are simply harder to target through exercise.
In contrast, Mesoline Slim acts on fat cells in specific areas, making targeted fat reduction a more achievable goal.
In addition, by reducing the number of fat cells that store triglycerides (lipids), the treatment may support a body composition that is less prone to weight gain and rebound.
Treatment Areas for Mesoline Slim | Upper Arms, Abdomen, and More
Mesoline Slim can be applied to the following areas:
- Upper arms
- Abdomen (including upper, lateral, and lower areas)
- Back
- Waist
- Thighs
- Buttocks
- Above the knees
- Calves
While injections to the face are not available, the treatment can be applied to a wide range of areas where fat tends to accumulate.
When Might You Notice Results from Mesoline Slim? A General Guide of 2–4 Sessions
As a general guide, noticeable results from Mesoline Slim may be experienced after approximately 2–4 sessions.
Areas such as the upper arms, back, and lower legs—where muscle and bone lie beneath the subcutaneous fat—tend to show visible changes more readily.
On the other hand, areas like the abdomen, where there is naturally a larger amount of subcutaneous fat, may take longer to show visible changes.
However, many patients find it easier to notice early signs of change, such as previously firm fat becoming softer to the touch.
How Long Do the Effects of Mesoline Slim Last?
Whether the effects of Mesoline Slim are maintained long-term depends on your lifestyle habits.
To help maintain results in areas where fat cells have been reduced through Mesoline Slim, it is important to follow a well-balanced diet and engage in regular, moderate exercise.
Please be aware that even after fat cells have been reduced, unhealthy habits such as overeating or excessive alcohol consumption may still lead to weight regain.
Are There Side Effects with Mesoline Slim? Points to Note Before and After Treatment

As with any treatment, Mesoline Slim has both benefits and points to be aware of:
- Swelling and puffiness may occur after treatment
- Some individuals are not eligible for treatment
The following sections explain each of these points in detail.
Note ① Swelling and Puffiness May Occur After Treatment
Please be aware that pain, swelling, and puffiness may occur after Mesoline Slim treatment.
Post-treatment discomfort is typically described as a dull, muscle-ache-like sensation. While this varies among individuals, it generally subsides within approximately one week.
Swelling and puffiness may persist for around two weeks but tend to gradually improve, so if the treated area appears puffy, this does not indicate that anything has gone wrong.
We recommend planning your treatment schedule with post-treatment swelling and puffiness in mind.
Additionally, please avoid strenuous exercise, prolonged bathing, and vigorous massage on the day of your treatment.
Note ② Some Individuals Are Not Eligible for Treatment
The following individuals are not eligible to receive Mesoline Slim treatment:
- Those with a soy allergy
- Those who are pregnant or breastfeeding
- Those with pre-existing conditions such as heart disease or high blood pressure
- Elderly individuals
- Those who have previously experienced serious adverse reactions to medications or food
- Those with immunodeficiency or autoimmune disorders
- Those with vascular insufficiency or microvascular disease
- Those currently undergoing cancer treatment
The primary active ingredient in Mesoline Slim, phosphatidylcholine, is mainly derived from soybeans. For this reason, individuals with a soy allergy are not eligible for this treatment.
If you have any other concerns, please consult with us before your treatment.

|---|---|---|---|
| Treatable Areas | Upper arms, abdomen, back, waist, thighs, buttocks, above the knees, calves | Face, around the face, neck, upper arms, abdomen, flanks, back, thighs, above the knees, calves | Chin, upper arms, flanks, abdomen, thighs, upper arms |
| Main Ingredients | ・Phosphatidylcholine ・Deoxycholic acid and others |
・Deoxycholic acid ・Methyl silanolmannuronate and others |
Fat-dissolving peptides and others |

| Recommended Number of Sessions | 3–5 sessions | 3–5 sessions | Approximately 4 sessions |

Differences Between Fat-Dissolving Injections (Mesoline Slim) and Liposuction

The table below outlines the key differences between fat-dissolving injections such as Mesoline Slim and liposuction.
| Treatment | Fat-Dissolving Injection | Liposuction |
|---|---|---|
| Discomfort | A few days | 1–2 weeks |
| Treatment Time | 5–10 minutes | 1–2 hours |
| Expected Effect | Breaks down and eliminates fat in a targeted area | Removes fat over a broader area in a single procedure |
| Key Features | ・Short treatment time ・Relatively short downtime ・Less suited to reducing fat over a large area |
・Results may be noticeable after a single session ・Can address fat across a larger area ・Greater physical burden on the body ・May leave scarring |
Liposuction can address fat over a broader area and may help improve the overall appearance of the body. However, the downtime tends to be longer as a result.
By contrast, while Mesoline Slim is less suited for large-area fat reduction, it is a treatment option that may be well-suited for those wishing to reduce fat in a specific area. Its relatively short downtime also makes it more accessible for many patients.

How the Mesoline Slim Treatment Works

Frequently Asked Questions About Mesoline Slim

Below are answers to frequently asked questions about Mesoline Slim.
Q. Can Mesoline Slim be injected into the face?
Mesoline Slim is a fat-dissolving injection intended for use on the body only.
As there is a risk of swelling and puffiness as part of the downtime, injections to the face are generally not performed.
If you are looking to slim the face or define the jawline, please consider the BNLS injection, which is available at IC Clinic.
