Fat-dissolving injection ‘MiliFit’,

For my own fit that doesn’t give way

Hello.

This is Mutuel Plastic Surgery Clinic.

Mutuel Clinic is a clinic in Yongsan with a three-doctor collaborative system, including board-certified plastic surgery and dermatology specialists, and we carefully analyze each patient’s condition to provide precise and balanced treatments.

What Mutuel values most is not only visible change, but also the comfort and trust patients feel throughout the entire process, from consultation to recovery after treatment or surgery.

A change that is not excessive, but definite.

To make that process reliable, we promise honest explanations and systematic aftercare so you can trust our care.

We will always provide care with sincerity to offer a better medical experience.

A double chin that hides the jawline,

submental fat that stands out especially in side-profile photos,

and people who don’t have much fat on their face but feel stressed because the fat is concentrated only under the chin, making them look heavy.

In particular, submental fat is often not greatly affected by changes in body weight,

and since it is “stubborn fat” that does not easily go away even with exercise or dietary control,

it is not easy to reduce on your own.

In the end, many people feel frustrated, wondering, “Why does the area under my chin stay the same even when I lose weight?”

But with advances in medicine, it is now possible to improve the jawline in a more precise and predictable way.

Today, we would like to explain in an easy-to-understand way one non-surgical option among them: the fat-dissolving injection ‘MiliFit,’ which was developed to target fat along the jawline and under the chin and has received approval from the Ministry of Food and Drug Safety.

We’ll walk through how the MiliFit injection reduces fat and why it is effective for improving the jawline.

What is MiliFit?

MiliFit is a fat-cell-destroying injection approved by the Korean Ministry of Food and Drug Safety (KFDA). It is a subcutaneous injectable treatment developed to improve moderate to severe accumulation of submental fat in adults.

Unlike common fat-dissolving injections that many people know about, the biggest feature of this injection is that it does not merely temporarily shrink fat cells; it irreversibly destroys the fat cells themselves.

Its main ingredient is deoxycholic acid (DCA), which does not contain steroids.

Deoxycholic acid physically destabilizes the cell membrane made up of the phospholipid bilayer of fat cells, destroying the cells themselves.

In other words, rather than reducing the volume of fat cells like a steroid preparation, it breaks down the structure of the cells themselves.

Because fat cells destroyed this way do not regenerate, a clear and permanent fat-reduction effect can be expected.

During the inflammatory response triggered by deoxycholic acid, a response that promotes collagen synthesis also occurs, so while fat is reduced and the jawline becomes more defined, there is also the advantage of improved skin elasticity.

The medication used is a clear, colorless liquid contained in a colorless transparent vial, and it is injected into the subcutaneous fat layer in 0.2 mL amounts at 1 cm intervals.

At Mutuel, based on the precise understanding of facial and skin anatomy by board-certified plastic surgery and dermatology specialists, we create and carry out the most suitable treatment plan for each individual.

What effects does it have?

Through the MiliFit procedure, you can obtain both fat-cell destruction and improved skin elasticity.

MiliFit’s ingredients destroy the fat-cell membrane and remove the cells themselves, allowing for a semi-permanent fat-reduction effect.

In addition, as fat cells are destroyed, a natural inflammatory response occurs, and at this time an increase in collagen synthesis appears.

Thanks to this, instead of only reducing fat while the surface skin sags, the jawline becomes tighter after the procedure.

It can also be applied to other areas of the body where fat accumulates, showing effects in various areas such as the upper arms, the front armpit area, the lower abdomen, the upper inner thighs, and buccal fat.

Who is it recommended for?

The following cases are those in which you may feel high satisfaction from the MiliFit procedure.

First, people who have a lot of fat under the chin and therefore have a developed double chin.

Some people do not have much facial fat, but only fat remains under the chin.

MiliFit can effectively reduce this kind of “localized fat.”

Second, people whose jawline has become blurred as facial elasticity decreases.

Because MiliFit brings about both fat reduction and collagen synthesis at the same time, it helps maintain skin elasticity without sagging even as fat decreases.

Third, people who want a balanced V-line and a more defined facial contour.

MiliFit improves a blunt jawline, tightens the contours, and tidies the overall facial line to create better balance.

For those who notice a double chin standing out only when taking side-profile selfies, satisfaction with this procedure can be especially high.

At Yongsan Plastic Surgery and Yongsan Dermatology Mutuel, we do our best to create results that suit each person best, based on accurate analysis and diagnosis before treatment.

Are there any precautions?

Although it is a medication with verified safety and effectiveness, because it works by destroying fat cells, injecting it into the wrong area may reduce its effect or cause side effects.

Therefore, it is important to receive the procedure from a specialist with precise anatomical knowledge.

After the procedure, reactions such as pain, warmth, and swelling may occur during the process of fat-cell destruction.

Most symptoms improve naturally within one week, so there is no need to worry too much.

Repeated treatments can be performed at intervals of at least one month, up to a maximum of six sessions, but the regimen may vary depending on the individual’s amount of fat and thickness.

In closing..

A double chin and submental fat often persist regardless of body weight, and they tend to stand out especially in photos, so they remain a concern for many people.

The deoxycholic acid injection ‘MiliFit’ fundamentally destroys fat cells and also increases collagen beneath the skin to help maintain elasticity, making it suitable for those who want a more defined jawline.

However, the area under the chin contains complexly located lymphatic structures, muscles, and nerves, and the anatomical structure varies greatly from person to person, so you must establish a detailed treatment plan after consultation with a specialist.

Through a collaborative system between plastic surgery and dermatology, Mutuel always provides care honestly and carefully, with sufficient effectiveness, fast recovery, natural change, and safety as the top priorities.

If you are worried about a double chin, do not simply brush it off by thinking, “I just need to lose weight,” and instead find the cause together with a specialist.

This has been Mutuel Plastic Surgery Clinic, always sharing your concerns right by your side.

Thank you.
