Hyaluronidase is an enzyme used by trained medical professionals to break down hyaluronic acid dermal filler. It gives doctors a precise way to adjust migrated, excessive or unwanted HA filler and helps suitable patients return towards softer, more natural facial contours.
What does hyaluronidase do?
Hyaluronic acid filler contains cross-linked HA gel designed to remain in the tissue. Hyaluronidase helps break down the bonds within that gel so the body can clear it. It is specifically used for hyaluronic acid filler and does not dissolve products made from other materials.
Why reversibility is a valuable part of HA filler treatment
The ability to adjust hyaluronic acid filler is one reason it remains widely used in aesthetic medicine. If a result no longer suits your features, filler has moved, or too much product has accumulated, a doctor can assess whether targeted dissolving could restore balance.
Does hyaluronidase damage your natural tissue?
Hyaluronidase is used to target hyaluronic acid, including cross-linked HA filler. The body naturally contains and continually replaces its own hyaluronic acid. The treatment plan is designed around the product and area being corrected. Temporary changes in hydration or softness can be noticed while swelling settles, but the aim is controlled correction and a healthier-looking, natural foundation.
How we make filler dissolving carefully planned and comfortable
Every treatment begins with a consultation. We review your medical history, allergies, previous filler treatments and the result you would like to achieve. Before elective treatment, we perform a patch test as part of our safety assessment. Allergy to hyaluronidase is uncommon, and this careful process helps us decide whether treatment is suitable for you.
The doctor then plans the amount and placement. Some areas respond quickly, while dense or heavily cross-linked filler may be treated gradually. A staged approach can be positive because it gives the doctor more control and helps preserve filler that is still contributing to a balanced result.
What can hyaluronidase help with?
- Migrated lip filler and blurred lip borders.
- Persistent puffiness associated with under-eye filler.
- Overfilled or heavy-looking cheeks.
- Lumps, unevenness and visible asymmetry caused by HA filler.
- A planned filler reset before a more natural treatment approach.
What should I expect afterwards?
Temporary swelling, redness or tenderness can occur around the treated area and usually settles. Your doctor explains aftercare and when to return for review. We do not rush into replacing filler. Allowing the tissue to settle can reveal your natural structure and help create a more refined future plan.
Natural-looking results are the goal
Many patients now want to look refreshed rather than filled. Dissolving does not mean that previous treatment was a failure. It can be a thoughtful reset that gives you and your doctor a clearer starting point. Some patients choose no further filler, while others later select a smaller, more precise treatment.
Why our approach begins with a consultation and patch test
At London Finsbury Clinic, elective filler dissolving begins with a doctor-led consultation. We examine the treated areas, review what product was used when this is known, and discuss your medical history, medicines and allergies. We also perform a patch test before elective hyaluronidase treatment. This gives us another useful safety check, although no test can promise that a reaction is impossible.
Hyaluronidase is widely used to break down hyaluronic acid filler. Most reported reactions are temporary and local, such as redness, swelling, itching or tenderness. Allergic reactions are uncommon, and careful assessment helps us plan the treatment responsibly and keep you informed at every step.
Why starting fresh can create a more natural result
If filler has migrated, accumulated or changed the balance of the face, adding more product may not give the clean and natural result you want. For a suitable patient, carefully dissolving the old hyaluronic acid filler can allow the features to settle before a new plan is considered. This can make future treatment more precise and help us protect the expressions and proportions that make you look like yourself.
Not everyone needs their filler dissolved. Our aim is to recommend it only when it is likely to improve the foundation for a refreshed, proportionate and long-lasting result.

Frequently asked questions
Does hyaluronidase dissolve every type of filler?
It is used for hyaluronic acid fillers. It does not dissolve non-HA products, so knowing the previous product is helpful wherever possible.
Can hyaluronidase be used selectively?
Yes. A doctor can plan treatment for a specific area and preserve product that remains well placed when clinically appropriate.
How quickly will I notice a change?
Changes can begin soon after treatment, but swelling may temporarily affect the appearance. The area is reviewed after it has had time to settle.
Is allergy to hyaluronidase common?
Allergy is uncommon. Your doctor reviews your history, and a skin test may be used where clinically appropriate before treatment.
Can I have filler again later?
Often, yes. Your doctor will advise when the area is ready and whether replacement filler is needed. A smaller and more natural plan may be recommended.
