Double Chin Fat-Dissolving Injections: Stages of Changing from a U-Line to a V-Line and 3 Types

Double chin fat-dissolving injections are a treatment that reduces the submental fat that doesn’t easily go away with dieting, helping to refine the U-line toward a V-line.

However, a double chin is caused not only by fat but also by swelling, skin elasticity, muscles, and structural issues,

so it is important to first identify your own type rather than getting a fat-dissolving injection without a second thought.

Hello,

I am Jong-geun Song, director of Pixel Lab Plastic Surgery in Sinnonhyeon.

As a board-certified plastic surgeon with 15 years of experience,

I have focused on the lower facial contour, running from the jawline down to the neckline,

and have been treating patients while carefully evaluating fat volume and distribution, skin elasticity, and bone structure together.

¶ Will my double chin go away if I lose weight?

“I’ve heard it goes away once you lose weight.

Do I really need a double chin fat-dissolving injection?”

Many people ask me this.

Some people online make it sound like a double chin disappears simply by losing weight.

In reality, fat under the chin is one of the areas that is slower to go away when dieting,

so a double chin often remains even after your body weight has dropped.

On top of that, due to innate bone structure or fat distribution, some people with slim builds still have a noticeable double chin.

That’s why the first thing I check in consultations is what cause and type of double chin you have.

Fat type: Submental fat is abundant with clearly defined borders
Swelling type: Rather than fat, swelling and circulation issues have a larger impact
Elasticity type: Reduced skin elasticity, where sagging has a larger impact
Muscle type: The platysma muscle in the neck has loosened, causing the jawline border to sag
Structural type: A short chin leaves too little space under the chin itself

¶ How does Harupit fat-dissolving injection work?

Double Chin Fat-Dissolving Injections: Stages of Changing from a U-Line to a V-Line and 3 Types 사진 3 — Four steps: 1) injection into double-chin fat; 2) fat cells swell, break down and shrink; 3) fat exits via lymph; 4) a cleaner V-line.

Harupit acts on the fat cells under the chin,

damaging the fat cells,

and then helps them gradually be eliminated through the body’s natural metabolic processes.

It is less a treatment that completes a V-line in one go,

and more a method that naturally refines a double chin as the fat volume decreases over time.

Harupit tends to work better for double chins that are primarily fat-based,

and if other types are mixed in, such as elasticity-related issues, injections alone have limitations,

so I consider other care, such as lifting, as well.

Results and responses can vary from person to person.

¶ How does the double chin type change the approach?

Double Chin Fat-Dissolving Injections: Stages of Changing from a U-Line to a V-Line and 3 Types 사진 4 — Three double-chin types: thick, defined chin fat; swelling and circulation issues more than fat; sagging from lost skin elasticity.

The double chin area differs between individuals in terms of fat layer thickness and distribution,

and important nerves and major anatomical structures run close to the jawbone.

So even with the same fat-dissolving injection,

how precisely it is placed into the right layer and area

has a major impact on both safety and results.

That is why, at Pixel Lab, I apply different Harupit combinations for each double chin type,

based on Pixel Lab’s clinical standards.

Harupit is administered based on treatment data from patients who have visited Pixel Lab,

taking into account the types of ingredients and even their mixing ratios.

Harupit is a recipe independently developed by Pixel Lab, and a patent application is currently pending.

In other words, unlike injections that simply administer a predetermined medication,

the treatment is designed with the balance of the face and body in mind, and is applied as a combination focused on the double chin according to the area and condition.

Reading the descriptions of the three types below should make things easier to understand.

Type	Characteristics	Consider this if
RED	Contains steroids	you want to see the speed of change first
GREEN	Non-steroidal	you want a gentler approach that reduces irritation
PURPLE	Contains deoxycholic acid (DCA)	the fat layer is prominent and you want a more active approach

Harupit comes in three types—RED, GREEN, and PURPLE—

and the right one should be chosen by considering the amount and distribution of fat, skin condition, and the direction of change you want.

In particular, because the fat layer under the chin is thin, accurate injection is important, and results vary from person to person for all treatments.

¶ How does the double chin line change after treatment?

A double chin doesn’t tidy up right after treatment,

but changes gradually in stages.

The procedure takes less than 10 minutes,

but swelling, slight pain, or bruising may occur afterward.

Timing	Skin and line condition	Key point
Immediately after	Swelling and a tingling sensation	Avoid irritation and calm the area
About 1 week	Fat cells break down and begin to be eliminated, and volume gradually decreases	Swelling begins to subside
About 1 month	Contour and lines are refined as the number of fat cells decreases	Maintain results with lifestyle care

(Recovery and progress vary from person to person.)

Some people notice a change in their contour after just one or two sessions,

but I usually recommend three or more sessions spaced two weeks to one month apart.

Drinking enough water after treatment helps eliminate the broken-down fat,

so I recommend drinking at least 2 liters of water a day and managing your diet as well.

The number of sessions and speed of response vary from person to person.

¶ Will just getting injections give me a V-line?

This is what I emphasize most in consultations.

Double chin fat-dissolving injections reduce the size of fat to refine the contour,

but they do not change bone or muscle structure.

So for the structural type I described earlier, where a short chin leaves too little space under the chin,

I recommend first building up the structure with a chin filler,

and for the muscle type, where the platysma muscle has loosened,

I recommend approaches that also address the muscle layer, such as surgery or Tri-Lift.

If the cause is not fat, repeating only injections makes it hard to achieve the change you are hoping for.

Along the same lines, many people worry about sagging after treatment.

With a procedure like typical liposuction, removing a large amount of fat at once can leave the skin loose.

Harupit, on the other hand, breaks down fat gradually and eliminates it, so the burden is generally lower.

However, if skin elasticity has already declined significantly, sagging can become more noticeable when only fat is reduced.

For these patients, we design a plan that considers elasticity care,

so that the contour and skin condition are refined together.

¶ Cases where I do not recommend treatment

Double chin fat-dissolving injections may not be suitable for everyone.

That’s why I carefully assess each patient,

and for those for whom this treatment is not suitable,

I honestly advise combining it with another procedure or tell them I do not recommend it.

Patients who are pregnant or breastfeeding
Patients with cardiovascular disease or a history of severe allergies
Patients with a bleeding disorder or who are taking anticoagulants
Patients with skin problems such as dermatitis or infection at the treatment site
Patients who expect an immediate V-line change from a single treatment

¶ Frequently Asked Questions (FAQ)

Q1. What’s the difference between double chin fat-dissolving injections and liposuction?

Liposuction is a surgical method in which an incision is made, a tube is inserted, and fat is physically removed.

While it can remove a large amount of fat in one session, it requires a recovery period, and the possibility of scarring at the incision site must also be considered.

Harupit, on the other hand, is a non-surgical method that uses injections to damage fat cells and help the body eliminate them.

The procedure takes less than 10 minutes and involves no incisions,

so you can achieve the change you want simply, without the burden of surgery.

However, the extent and speed of change vary from person to person, and treatment is carried out over several sessions.

I consider the amount and type of double chin fat, as well as how much time you have for recovery, before recommending a direction.

Q2. What should I keep in mind after a fat-dissolving injection?

Immediately after treatment, you may experience swelling along with a tingling sensation.

To avoid irritating the treated area, please avoid massage, saunas, alcohol, and intense exercise for about a week.

It’s also a good idea to drink plenty of water so the broken-down fat can be eliminated smoothly.

Responses and recovery speed after treatment vary from person to person.

Q3. What ingredients are used in fat-dissolving injections?

Fat-dissolving injections differ in ingredients and mechanisms depending on the product.

For double chin, however, it’s more important to first determine whether the cause is fat, swelling, or elasticity than to choose a stronger ingredient.

At Pixel Lab, after evaluating the type of double chin, the amount of fat, and skin condition, we decide on the appropriate Harupit type—RED, GREEN, or PURPLE—and its combination.

Rather than simply reducing as much fat as possible,

it’s important to create gradual changes to the contour while considering the balance of the entire face.

That’s why I thoroughly explain each patient’s facial structure and the cause of their double chin,

and decide on a direction for natural-looking results together with them.

We recommend getting a thorough evaluation from medical professionals who can accurately assess your double chin type and skin condition and suggest a treatment direction suited to you.
