Hongdae V-Olet Double Chin Injection: If your jawline doesn't reappear even after weight loss.

April 23, 2026

Hello.

I am Director Dong-young Kim of Cleor Clinic Hongdae.

"I'm worried about my double chin that remains even after losing weight."

"I can't really tell where my jawline ends."

Among those concerned about a double chin,

there are more people than you might think who have given up on dieting.

Even after working hard to lose weight, the area under the chin remains the same,

and in some cases, the skin sags as the weight drops,

making it look even more prominent.

This is not a matter of willpower.

Structurally, the fat under the chin

is an area that is difficult to reach through exercise and diet alone.

This means the approach itself must be different.

Today, among the double chin injections in Hongdae,

I will speak candidly about

the principles and realistic expectations of V-Olet,

which directly targets double chin fat.

Why double chin fat is hard to lose

The subcutaneous fat layer under the chin has slow lymphatic circulation,

and skin elasticity decreases earlier than in other parts of the face.

As skin tissue weakens with age,

it becomes a structure where fat easily sags and accumulates downward.

Even if you lose weight, the fat cells in this area

only decrease in size; they do not disappear.

Therefore, when a yo-yo effect occurs or time passes,

it often returns to its original state.

How does V-Olet work?

The main ingredient of V-Olet is

Deoxycholic Acid (DCA).

DCA is a substance that naturally exists as bile acid in our bodies,

playing a role in emulsifying fat to aid absorption during digestion.

When this ingredient is refined for medical use

and injected directly into the subcutaneous fat layer under the chin,

it targets the fat cell membranes and destroys the membranes themselves.

To use an analogy:

General contouring injections are like pressing down on a sponge to make it flat.

When the pressure is released, it swells back up.

V-Olet is closer to a method of removing the sponge itself.

👉The destroyed fat cells are excreted from the body,

and collagen synthesis is induced in their place,

which also helpsmaintain skin elasticity.

Because it reduces the number of fat cells rather than just their size,

it works to maintain the effect for a longer period.

What kind of product is V-Olet?

V-Olet is a specialized medical product for double chins developed by Daewoong Pharmaceutical,

containing DCA,

and it received MFDS approval in 2021.

The same DCA ingredient has already been approved by the US FDA and European health authorities,

so the mechanism and safety of the ingredient

have been verified over a relatively long period.

As the product with the longest-accumulated clinical data among Korean-made DCA injections,

it approaches double chin improvement through two actions:

fat cell destruction and collagen synthesis induction.

However, the DCA ingredient does not react selectively only to fat cells;

it can also affect other tissues,

so the design of the injection site and depth is crucial.

This is why the design stage before the procedure is handled with great care.

How is the procedure performed?

After applying numbing cream,

it is injected in small amounts into the subcutaneous fat layer under the chin.

The procedure takes about 10 to 20 minutes, and you can return to your daily routine on the same day.

The effects begin to appear gradually after one month, rather than immediately after the procedure.

This is because a process is required

for the fat cells to be destroyed and the debris to be excreted from the body.

Generally, 2 to 3 sessions at 4-week intervals are recommended.

Since the number of sessions varies depending on the amount and distribution of fat,

it is appropriate to check the results after one session and then decide on additional treatments.

Swelling, bruising, and temporary pain may occur after the procedure.

It is a natural reaction for a local inflammatory response to accompany

the process of the DCA ingredient destroying fat cell membranes,

and swelling may last for more than a week.

If you have an important schedule, it is recommended to receive the treatment at least two weeks in advance.

It is an option for the following people:

  • Those whose chin fat remains even after dieting

  • Those who felt that general contouring injections were insufficient

  • Those who want to structurally approach a double chin without surgery

It serves as an effective option.

If there is active inflammation in the treatment area, if skin sagging is the main cause,

if there is a history of allergies to specific ingredients,

or if you are pregnant or taking blood-related medications,

a consultation is required before the procedure.

⚠️ Precautions

Please avoid saunas, jjimjilbangs, and hot tubs for several days

as they can worsen swelling.

It is recommended to refrain from alcohol and strenuous exercise for about a week

as they can stimulate inflammatory reactions in the body.

Please also refrain from pressing hard on or massaging the treatment area.

It is accurate to judge the results at least one month later.

If you judge the effect before the swelling goes down, it may seem less significant than it actually is.

❓ Frequently Asked Questions

Q. Can I get the Hongdae double chin injection V-Olet just once?

While some people notice changes after one session,

many often experience more distinct results

through 2 to 3 cumulative sessions.

Rather than booking multiple sessions from the start,

we recommend checking the results after one session and then deciding on the next steps.

Q. When does the swelling go down after the V-Olet procedure?

It varies depending on individual reactions,

but it usually subsides within 1 to 2 weeks.

Since the contour gradually appears as the swelling goes down,

it is accurate to check the final results after one month.

Q. How can I tell if my double chin is fat or skin sagging?

When you pinch the flesh under your chin,

if you feel a soft lump, it is highly likely that fat is the main cause.

If the skin feels saggy without anything to grab,

skin sagging may be the cause.

Since both often occur together,

we will provide guidance after a physical examination during your visit.

Q. Is the effect permanent after receiving V-Olet?

The destroyed fat cells themselves do not return.

However, if there is significant weight gain or hormonal changes,

the remaining fat cells may enlarge,

making the area look prominent again.

Weight management after the procedure is important for maintaining results.

Q. Can I receive it along with other procedures?

It is sometimes performed in combination with lifting procedures or Botox.

We will guide you on which combination is right for your current condition

after a direct consultation.

A double chin is often difficult to address through exercise and diet alone due to the characteristics of the area, not a lack of effort.
