Uijeongbu Filler Removal Injection: How to remove Hyaluronic Acid fillers?

May 13, 2026

Hello!

I am Director Hyuk-chan Cho of Cleor Clinic Uijeongbu Branch.

There are moments when a friend you haven't seen in a while looks at a photo and says something.

"Your lips look a bit swollen."

"The tip of your nose looks a bit different."

Even after staring in the mirror for a long time,

it's a change you didn't notice, but someone else did first.

Fillers received in the past may, over time,

have settled awkwardly or been injected in excessive amounts.

To answer the question, "Is there a way to remove it now?" let me give you the conclusion first.

Fillers made of Hyaluronic Acid (HA) can be resolved with dissolving enzyme injections.It is possible.

Today, for those looking into Uijeongbu filler removal injections,

I will honestly explain high-purity liquid Hylase, Hylax.

These are the types of people who usually look into this.

The reasons why patients inquire about Uijeongbu filler removal injections in the consultation room are diverse.

Let me first summarize the most common cases.

Why would you want to remove filler?

Filler that you liked when you first received it

can feel different over time for several reasons.

1) Filler can migrate from its original position

Once injected, filler does not stay in the same position forever.

The position can shift slightly due to facial movements, massage stimulation, or weight changes.

2) The volume becomes more prominent over time

An amount that looked natural at first may become relatively more noticeable

as facial contours change over time.

3) Lumping over time

Cases have been reported where filler creates a hard lump due to changes in cross-linking.

What is Uijeongbu Filler Removal Injection?

Uijeongbu filler removal injection is not a surgical incision method.

It is a method of injecting a dissolving enzyme called Hyaluronidase

into the area where the filler is located to dissolve it.

As a dissolving enzyme that acts precisely only on the filler component (Hyaluronic Acid),

it can selectively dissolve only the settled filler.

Why is only Hyaluronic Acid dissolved?

Most aesthetic fillers are made of Hyaluronic Acid,

a substance that naturally exists in our bodies.

Hyaluronidase is an enzyme that hydrolyzes this Hyaluronic Acid,

breaking down the Hyaluronic Acid in the filler into small fragments.

The dissolved fragments are naturally absorbed and excreted through the body's metabolism over time.

What is Hylax?

Cleor Clinic Uijeongbu Branch uses 1cc of high-purity liquid Hylase, Hylax, for the procedure.

Hylax is a liquid Hyaluronidase launched by Korea BMI.

It is a pharmaceutical product officially approved by the MFDS and has been used in the medical field for many years.

  • How is it different from existing products?

Hyaluronidase used in the past was in the form of freeze-dried powder.

Using raw materials extracted from ovine testes, there was a possibility of containing foreign proteins derived from sheep,

and the potential for redness, itching, and rarely, strong allergic reactions has been pointed out.

Additionally, a reconstitution process to dissolve the powder in water was required before use.

Improvements made by Hylax

To use an analogy, it's similar to the evolution from dissolving freeze-dried formula in water every time

to ready-to-drink liquid milk.

The most important aspect we check in Uijeongbu filler removal injections isAllergy Check.

Although Hyaluronidase is a dissolving enzyme,

it is a component that can cause allergic reactions in some patients..

A minute amount is test-injected into the skin surface to observe the reaction.

If the test results show redness, itching, or a strong reaction, the procedure cannot be performed.

Information to provide in advance

  • Whether you had a reaction if you have experience with Hyaluronidase procedures

  • Lamb/Mutton allergy (possibility of cross-reactivity)

  • History of drug allergies

  • Diagnosis of autoimmune diseases

  • Pregnancy or breastfeeding

Safety is first confirmed through testing and prior consultation.

Precisely with a fine needle

Since it is an injection method, it is not a highly irritating procedure.

If necessary, anesthetic cream is applied before proceeding.

Immediately after the procedure, slight redness, mild swelling, or small bruises may appear in the area.

Most subside within a few days, but recovery speed varies from person to person.

Changes occur gradually over several days

The process of the enzyme dissolving the filler begins immediately after the procedure and progresses over several days.

All changes are not visible at once; the area slowly settles over about 3 to 7 days.

Advantages of Uijeongbu Filler Removal Injection

There are also clear limitations to Uijeongbu filler removal injections.

It only acts on Hyaluronic Acid (HA) components

All Hyaluronidases, including Hylax, can only dissolve HA components.

Representative HA-based fillers include products like Belotero, Juvederm, and Restylane,

and these products can be dissolved.

On the other hand,PLLA collagen boosters (Sculptra, Olidia), CaHA series (Radiesse),

permanent fillers like silicone, Aquafilling, or PMMA, and

fat grafts or some collagen stimulators cannot be dissolved by Hyaluronidase.

If the amount of filler is large or it has been settled for a long time,

it may not all dissolve in one session, and additional procedures may be required.

Additionally, the natural Hyaluronic Acid in your body

in the same area may be temporarily affected.

It is known to recover naturally within a few days.

Results vary by individual

The degree of dissolution varies depending on the type of filler, degree of cross-linking, location, and amount.

We will confirm this during the prior consultation.

⚠️Post-Procedure Precautions

  • Please avoid saunas, jjimjilbangs, strenuous exercise, and alcohol on the day of the procedure.

  • When body temperature rises, irritation in the treated area tends to last longer.

  • Please refrain from strong massage or pressure on the treated area for a few days.

  • Since changes appear over several days, observe the area and confirm with an additional consultation if necessary.

Cases requiring immediate visit

  • Persistent severe pain

  • Allergic rash or itching

  • Difficulty breathing or dizziness

  • Swelling that does not subside for several days

If these reactions occur, please visit the clinic immediately.

❓ Frequently Asked Questions

Q. I don't know if the filler I received is HA. Can I still get a consultation?

Yes, during the prior consultation, we check the condition of the treated area along with information about the filler you received.

Bringing a receipt or procedure records allows for more accurate guidance.

Even if there are no records, there is information that can be confirmed during the diagnostic stage, which we will examine together.

Q. How long after Uijeongbu filler removal injection can I get new filler?

It is common to proceed after the action of Hylax is complete and the area has stabilized.

The recommended interval varies depending on the area and amount, and we will guide you during the prior consultation.

Q. When will I see the effects?

Dissolution begins immediately after the procedure, and the extent of change often becomes most apparent between 3 to 7 days.

It is difficult to say uniformly as there are individual differences.

Q. Is it possible during pregnancy?

Generally, the procedure is difficult to perform during pregnancy or breastfeeding.

We will confirm this during the prior consultation.

Q. What are the possible side effects?

Temporary redness, swelling, bruising, and tenderness may occur.

Rarely, allergic reactions (itching, rash, respiratory-related reactions)

have been reported, so we conduct a skin reaction test before the procedure and observe the progress afterward.

Cases that must be checked during prior consultation

  • If you are pregnant or breastfeeding

  • If you have active inflammation or a history of herpes in the treated area

  • If you have a history of allergic reactions to Hyaluronidase

  • If you have a history of lamb/mutton allergy (possibility of cross-reactivity)

  • If you have a history of autoimmune disease diagnosis

  • If there are non-hyaluronic acid-based fillers or implants in the treated area

  • If you are regularly taking anticoagulants

Depending on skin condition and medication history,

the procedure may not be suitable, which we will confirm during the prior consultation.

Filler removal requires as much caution as filler injection.

Leaving misplaced filler as it is can increase the burden over time,

and trying to fix it in the wrong way can add more irritation.

High-purity liquid Hylase, Hylax, used in Uijeongbu filler removal injections,

is a liquid product with improved safety compared to existing freeze-dried products and is a pharmaceutical approved by the MFDS.

Since it may not all be removed at once and there is a possibility of allergic reactions,

a skin reaction test and prior consultation before the procedure are important.

We will confirm this during the consultation.
