Hyaluronidase: How to Dissolve Botched Fillers?
A significant portion of patients coming to my clinic are people who are not satisfied with fillers they've had done elsewhere. Asymmetric lips, lumpy cheeks, blue tones appearing under the eyes... Most of these problems can be corrected.
In this article, I explain in detail the filler dissolving procedure with hyaluronidase enzyme, its indications, and the process.
What is Hyaluronidase?
Hyaluronidase is a natural enzyme that breaks down hyaluronic acid molecules. This enzyme, which is also found in the human body, is produced synthetically for medical purposes.
The mechanism of action of hyaluronidase is to break down the glycosidic bonds in HA chains, dividing the molecule into smaller pieces. These pieces are then naturally metabolized and excreted by the body.
Clinical Perspective
Hyaluronidase is the most valuable "safety net" in aesthetic medicine. The reversibility of HA fillers provides a great advantage compared to permanent filler types. That's why I always recommend HA-based fillers to my patients — if the result is not liked or complications develop, we have a chance to correct it.
In Which Situations is Filler Dissolved?
Main indications for hyaluronidase use:
🔄 Aesthetic Dissatisfaction
In cases of overfilling, asymmetry, unnatural appearance, expectations not being met.
⚠️ Vascular Compression
When filler compresses a blood vessel, urgent intervention is required. Skin whitening or bruising is an alarm sign.
🔵 Tyndall Effect
When superficially applied filler gives a bluish color, especially under the eyes.
📍 Nodule / Lumpiness
When filler doesn't distribute homogeneously and forms lumpy structure, hardness that doesn't resolve with massage.
🔁 Migration
When filler moves from the injected area to other areas over time.
🧬 Delayed Reaction
In rare biofilm formation or suspected granulomatous reaction.
How Does the Dissolving Process Work?
Evaluation and Planning
The existing filler is analyzed: which area, how much product is there, what type of complication? Sometimes all filler needs to be dissolved, sometimes intervention only to specific points is sufficient.
Allergy Test (If Necessary)
Because hyaluronidase is of animal origin, there is a rare risk of allergy. A small test dose may be given first, especially in those with a history of bee allergy.
Local Anesthesia
Topical anesthetic cream or local injection is applied to the area to increase procedure comfort.
Hyaluronidase Injection
The enzyme is injected into the area where the filler is located with fine needles. The dose is calculated according to the amount of filler to be dissolved. The procedure takes 10-20 minutes.
Waiting and Follow-up
The enzyme shows its effect within 24-48 hours. Mild swelling during this time is normal. A follow-up appointment is given 1-2 weeks later for result evaluation.
What Happens After Dissolving?
Expected process after hyaluronidase application:
- First 24-48 hours: Enzyme actively works, filler dissolves
- Mild swelling and redness: Normal, subsides within a few days
- 1-2 weeks: Final result appears, tissue returns to normal
- 2-4 weeks later: New filler application can be done if desired
Risks and Complications
While hyaluronidase is generally a safe procedure, the following risks exist:
- Allergy: Rare (less than 0.1%), but can be serious. Caution in those with bee allergy history
- Over-dissolving: More volume loss than expected may occur
- Swelling and bruising: Temporary, 3-7 days
- Asymmetry: Correction may be needed in case of unequal dissolving
Frequently Asked Questions
Is hyaluronidase painful?
Local anesthesia is applied before the procedure. A slight stinging sensation may occur during injection but it is at a tolerable level. Most patients find this easier than filler application.
Does all filler dissolve in a single session?
Usually a single session is sufficient. However, a 2nd session may be needed for very dense or high cross-link fillers. This is evaluated at the follow-up examination.
Can filler be done again after dissolving?
Yes. Hyaluronidase completes its effect in 24-48 hours. After waiting 2-4 weeks for the tissue to fully heal, a new and correct filler application can be safely performed if desired.
Will my face return to its original state after dissolving?
Yes, when filler is completely dissolved, tissue returns to its pre-filler state. No permanent deformation or scarring remains.
