Filler Dissolving Injection

Filler Dissolving Injection in Seoul

Doctor profile · Doctorpetit Clinic Hongdae, Seoul

A filler dissolving injection is a corrective treatment that uses hyaluronidase, an enzyme, to break down hyaluronic acid (HA) filler that has left too much volume, an uneven result, or a filler-related problem. At Doctorpetit Clinic Hongdae in Seoul, Korea, the injection usually takes about 15 to 30 minutes, and the clinic states that absorption can begin within a few hours and usually happens within 24 to 48 hours. The area is then reassessed to decide whether anything further is needed.

What Is a Filler Dissolving Injection?

A filler dissolving injection is the placement of hyaluronidase into or around existing HA filler so that the enzyme breaks the gel down and the body can absorb it.

• Enzyme action. Hyaluronidase cleaves hyaluronic acid, the main component of HA fillers, which lets the injected gel lose its structure.
• HA only. The enzyme works on hyaluronic acid. Many non-HA and permanent fillers cannot be dissolved this way.
• Partial or complete. Depending on the goal, the doctor may aim to soften an overfilled area or to remove most of the filler.
• Variable response. How completely filler dissolves depends on the product type, how cross-linked and concentrated it is, where it sits, and how much enzyme is used.
• Natural HA is affected too. Hyaluronidase can also act on the hyaluronic acid your skin already contains, which is why the final volume loss can be hard to predict precisely.

People usually seek dissolving for one of two reasons. The first is aesthetic: a result that looks heavier, lumpier, or less symmetrical than intended, or filler that has drifted from where it was placed. The second is medical: certain filler-related complications for which breaking down the gel quickly is part of management. The clinic describes hyaluronidase as being used when side effects, excess volume, or asymmetry appear after HA filler, including for urgent management and for touch-ups.

Hyaluronidase is widely used for HA filler problems, but the controlled evidence base is still small. A 2022 scoping review of its use in managing aesthetic complications identified only five randomized controlled trials, all small and all on uncomplicated nodules (Scoping review, PMC).

Who Performs Filler Dissolving Injection at Doctorpetit Clinic Hongdae

Dr. Chae-ho Lee
Medical Director at Doctorpetit Clinic Hongdae

Filler dissolving injections at Doctorpetit Clinic Hongdae are performed by Dr. Chae-ho Lee, the Medical Director and the clinic's sole physician. Dermal fillers are one of his stated core specializations, and he is a member of the Korean Filler Society. Before injecting any enzyme, he establishes what filler was used, where and when it was placed, and what is causing the problem. Because he also performs the clinic's filler treatments, the same doctor can judge whether a dissolved area later needs re-treatment or is best left to settle.

Who Is a Good Candidate for Filler Dissolving Injection?

A physician must examine the existing filler and the treatment area before deciding. Dissolving may be appropriate for:

• People with HA filler that looks excessive, overfilled, or heavier than intended.
• People whose filler result is asymmetrical or uneven.
• People with filler that has migrated away from where it was injected.
• People with lumps or nodules from HA filler.
• People with certain filler-related complications that a doctor judges should be managed by dissolving.
• Patients who had HA filler at another clinic and want it corrected or removed before deciding on next steps.

Dissolving may not be suitable, or may need to be postponed, for:

• People whose filler is not hyaluronic acid, since many non-HA and permanent fillers do not respond to the enzyme.
• Anyone with a known allergy or hypersensitivity to hyaluronidase or its components.
• People with an active skin infection or inflammation at the injection site.
• Anyone with allergies or medical circumstances that make an alternative approach safer.

Why the examination comes first

Dissolving is not decided from a photo or a description alone. The doctor needs to establish four things: what filler was injected, where it was placed, when it was placed, and what exactly the filler-related problem is. He then assesses the tissue itself. If the product turns out not to be hyaluronic acid, the enzyme is unlikely to help and other approaches have to be discussed. If the filler is HA, the examination also guides how much enzyme to use and whether the aim is a partial softening or a more complete removal. Only after this assessment does dissolving become the plan.

What to Expect: Procedure, Recovery, and Results Timeline

Information to bring

The most useful thing you can bring is a record of your earlier treatment. If you know it, tell the doctor the brand of filler, where it was injected, the approximate date, and how much was used. Also share your medical history, allergies (especially any reaction to hyaluronidase), medications, and supplements. Mention anything that might increase bruising, such as blood-thinning medicine or alcohol, but do not stop a prescribed medication without medical advice.

The procedure, step by step

1. Consultation. Dr. Lee examines the area and the filler, reviews your history, and decides whether dissolving is the right step.
2. Preparation. The skin is cleansed and the area to be treated is marked.
3. Injection. Hyaluronidase is injected carefully into the targeted filler.
4. Dissolving. The enzyme begins to break down the HA gel.
5. Assessment. The area is checked, and additional treatment may be considered if needed.
6. Aftercare. You receive simple instructions for the days that follow.

Little or no anesthesia is usually needed. A topical numbing cream or local anesthetic may be used depending on the area and your preference. Expect mild stinging, pinching, or pressure during injection.

Recovery and results timeline

When	What to expect
Within a few hours	Filler absorption may begin.
24–48 hours	The clinic states that absorption usually occurs by this point.
A few days to about a week	Mild bruising and swelling are common and gradually fade.
After absorption	The area is reassessed to decide whether more dissolving or a corrective step is needed.

Recovery varies with the injection area and how much filler was treated.

Aftercare

Avoid vigorous massage of the area and unnecessary pressure until the doctor advises otherwise. Follow the individual instructions you are given. Seek medical attention promptly for severe or rapidly worsening swelling, breathing difficulty, widespread allergic symptoms such as hives, severe pain, skin discoloration, or any visual symptoms.

Planning a stay in Seoul

Dissolving is an outpatient procedure, so a long stay is not needed for recovery. The clinic suggests that around one to two days in Korea is generally sufficient, which allows for the treatment and a follow-up check if needed. Discuss air travel timing with Dr. Lee, particularly if swelling develops.

Combining Filler Dissolving Injection with Other Treatments

After the enzyme has worked, the area is reassessed to decide whether additional dissolving or a corrective treatment is needed.

• Further dissolving — if the first session leaves more filler than intended, a second round of hyaluronidase can be considered at the reassessment.
• Corrective treatment — any further step is chosen by Dr. Lee after the reassessment, not planned in advance.

Whether and when to add new filler is decided only after the dissolved area has been checked, so that the doctor is working from the settled tissue rather than from a swollen or partly treated area.

Doctorpetit Clinic Hongdae frequently accepts international patients who want non-surgical correction or volume rebalancing after an asymmetrical or overfilled result elsewhere. Every corrective case starts with an in-person look at the existing filler, because the right plan depends on what was injected.

Safety, Precision, and Clinic Standards

• Since January 2023, the clinic has appeared on the Ministry of Health and Welfare's list of medical institutions that may attract foreign patients.
• Dr. Chae-ho Lee examines the filler and performs every dissolving injection.
• Each case begins with a 1:1 personalized consultation.
• The clinic names hyaluronidase for dissolving and Juvederm and Atiere as its HA filler lines.
• According to the clinic, genuine products are used at labeled dosages.

Possible side effects and risks

Temporary pain, swelling, redness, bruising, itching, and tenderness are the effects people most often notice. Allergic or hypersensitivity reactions can occur, and infection or other injection-related complications are possible. Because hyaluronidase can also affect the skin's own hyaluronic acid, a treated area may lose slightly more or less volume than expected.

Hyaluronidase products carry label contraindications for people with known hypersensitivity to the enzyme, and allergic reactions, including hives and anaphylactic-like reactions, have been reported; a preliminary skin test is described in the prescribing information (DailyMed). The U.S. FDA also notes that removing or reducing filler may require injections, surgery, or other interventions with their own risks, and that removal can be difficult or impossible for permanent fillers or fillers that are not made of materials such as hyaluronic acid (FDA).

The Bottom Line

• A filler dissolving injection uses hyaluronidase to break down unwanted hyaluronic acid filler.
• It is used for excess volume, asymmetry, migration, lumps, and certain filler-related complications.
• At Doctorpetit Clinic Hongdae, Dr. Chae-ho Lee examines the existing filler before deciding whether to dissolve it.
• The injection takes about 15 to 30 minutes, and absorption usually occurs within 24 to 48 hours.
• Results are reassessed afterward, and non-HA fillers may not respond to the enzyme.

Frequently Asked Questions

How quickly does filler dissolve?
The clinic states that absorption can begin within a few hours of the injection and usually occurs within 24 to 48 hours. The exact timing depends on how much filler is present, its type, and the amount of enzyme used.

Will dissolving remove all of my filler?
Not always. The outcome can be partial or complete, depending on the filler type, its cross-linking and concentration, its location, and the dose. The area is checked afterward to see whether another session is needed.

Can hyaluronidase dissolve any type of filler?
No. It works on hyaluronic acid filler. Many non-HA and permanent fillers cannot be broken down with this enzyme, which is why knowing what you were injected with matters.

I had filler at another clinic. Can Doctorpetit Clinic Hongdae correct it?
The clinic frequently sees international patients seeking correction after overfilled or uneven results elsewhere. Bring whatever records you have about the product, area, date, and amount, and Dr. Lee will examine the filler before recommending anything.

Is the injection painful?
Most people feel mild stinging, pinching, or pressure. Topical numbing cream or local anesthetic may be used depending on the area and your preference.

Could I lose more volume than I wanted?
It is possible. Hyaluronidase can also act on the hyaluronic acid naturally present in your skin, so the precise amount of volume lost can be hard to predict. Dr. Lee adjusts the plan to the area and reassesses after absorption.

How many days should I stay in Seoul?
Dissolving is an outpatient procedure, and the clinic suggests that around one to two days in Korea is generally enough for the treatment and a check if needed.

When can I have new filler after dissolving?
That is decided after the area has been checked once the enzyme has worked. Dr. Lee will tell you whether further correction is appropriate and when.
