Filler Dissolving with Hyaluronidase: When You Need It and What to Expect — Istanbul

Q: How long does hyaluronidase take to work?

Hyaluronidase usually dissolves HA filler within 24–48 hours . Swelling from the injections can hide the change at first, so the result is judged once the area has settled. If some filler remains, a further session can be planned; sometimes more than one is needed.

Q: Can I get filler again after hyaluronidase?

Yes. Our physicians usually wait about 2 weeks after dissolving: by then the swelling has gone down and the enzyme has finished working, so your real starting point is visible. Injecting new filler earlier makes the result harder to judge. As with all cosmetic injectables, new filler is only for patients aged 18 and over.

Q: Does hyaluronidase dissolve Radiesse or Sculptra?

No. Hyaluronidase only works on hyaluronic acid . It does not dissolve Radiesse (calcium hydroxylapatite, CaHA), Sculptra (poly-L-lactic acid, PLLA) or permanent fillers such as silicone, PMMA or paraffin, which our clinic does not use. This is why it matters to know which product was injected.

Q: Is an allergy test needed before hyaluronidase?

For planned dissolving, a small skin test may be done first, because hyaluronidase is an enzyme and can rarely cause an allergic reaction. Tell us about any allergies and previous reactions. In an emergency such as vascular occlusion, treatment is urgent: restoring blood flow takes priority, and your physician decides how to proceed.

Q: Can you dissolve filler that was done at another clinic?

Yes, if it is an HA filler . Bring the product name, the date and any records you have. If the product is unknown, our physicians assess the area and explain what can realistically be expected, because non-HA fillers will not respond. You can start with photos by WhatsApp or a video call.

Filler dissolving is what makes hyaluronic acid (HA) filler reversible. The enzyme hyaluronidase breaks down HA gel, usually within 24–48 hours. Our physicians use it to correct lumps, filler that has moved, a bluish tint under the eyes or overfilled lips — and, in an emergency, to treat a blood vessel blocked by filler. This guide covers when dissolving makes sense, the allergy test, the procedure, swelling, when you can have filler again and what hyaluronidase cannot dissolve.

Why HA Filler Can Be Dissolved — and Other Fillers Cannot

HA filler is a gel made of hyaluronic acid, a substance that also occurs naturally in the skin. Hyaluronidase is an enzyme that breaks this gel down so that the body can clear it. This is why our physicians inject HA dermal fillers only with hyaluronidase on hand.

The enzyme works on HA only. It does not dissolve Radiesse (CaHA), Sculptra (PLLA) or permanent fillers such as silicone, PMMA or paraffin, which our clinic does not use. So before any treatment, we need to know what was injected.

When Is Filler Dissolving Needed?

Lumps and nodules

Small lumps can often be massaged. Firm or persistent ones, including nodules that appear later, may be dissolved after assessment.

Filler migration

Filler that has moved beyond where it was placed — for example above the lip border — can be dissolved to restore a clean shape.

Tyndall effect

A bluish tint in thin skin, for example under the eyes, when HA sits too close to the surface. See also tear-trough filler.

Overfilled lips

Lips that look too full after repeated treatments can be reduced, sometimes over more than one session. A lighter lip filler plan can follow if you wish.

Asymmetry or an unwanted result

If the result is uneven or not what you wanted, dissolving offers a way back.

Emergency: vascular occlusion

If filler blocks a blood vessel, hyaluronidase is the emergency treatment — rare but urgent; see the warning signs below.

Emergency Warning Signs After Filler

Vascular occlusion — filler blocking a blood vessel — is rare but serious. Contact the clinic immediately if you notice any of these signs after filler; if you are far from Istanbul, also seek urgent local medical care.

Severe pain, or pain that keeps increasing
Skin turning pale, white, dusky or mottled
Skin that feels cold
Any change in vision — very rare, and always an emergency

How Hyaluronidase Works and How Fast

Hyaluronidase is injected with a fine needle into the area of filler. It breaks the links that hold the HA gel together, and the body then clears the pieces. HA filler usually dissolves within 24–48 hours.

Sometimes more than one session is needed, so the result is reviewed before any further treatment is planned.

Allergy Test Before Dissolving

Hyaluronidase is an enzyme and, like any medicine, can rarely cause an allergic reaction. Before planned dissolving, our physicians may do a small skin test and check the result before treating. Tell us about any allergies, previous reactions and the medicines you take.

In an emergency such as vascular occlusion, restoring blood flow comes first, and your physician decides how to proceed.

The Procedure, Step by Step

Assessment

We ask what was injected, when and where, and examine the area. Bring the product name if you know it — especially if your filler was done elsewhere. Photos are taken only with your consent.

Skin test

For planned treatment, a small allergy test may be done first.

Injection

The skin is cleaned and hyaluronidase is placed with a fine needle where the lump, excess or migrated filler is. We use as little as needed.

Review

We check the result once the area has settled. If filler remains, a further session can be planned.

Swelling After Hyaluronidase

Mild swelling, redness or tenderness at the injection points is common and temporary. Because swelling can hide the change at first, the result is judged once the area has settled.

The area may also look a little flat or uneven for a short time, partly because the enzyme briefly acts on the skin's own hyaluronic acid, which the body naturally replaces. Your physician will tell you whether to gently massage the area or leave it alone.

Can You Get Filler Again After Dissolving?

Yes. We usually wait about 2 weeks before new filler, so that swelling has settled and we can see your true starting point. The new plan may use a smaller amount, a different product or another technique, so that the same problem does not return.

As with all cosmetic injectables, new filler is only for patients aged 18 and over. After any new treatment, follow the usual filler aftercare.

Radiesse (calcium hydroxylapatite, CaHA)	No — not an HA filler
Sculptra (poly-L-lactic acid, PLLA)	No — not an HA filler

Frequently Asked Questions

How long does hyaluronidase take to work?

Injecting new filler earlier makes the result harder to judge. As with all cosmetic injectables, new filler is only for patients aged 18 and over.

Can you dissolve just part of my filler?

Hyaluronidase is placed where the problem is — a lump, an area of migration or an overfilled part — so treatment can be targeted. The effect is not always precise, so our physicians use as little as needed and review the result before doing more. If filler remains, a further session can be planned.

Will dissolving make my lips smaller than before filler?

It should not cause a lasting loss of your natural volume. The enzyme can briefly act on the skin's own hyaluronic acid, which the body naturally replaces, so lips may look a little flat for a short time before they settle. Naturally full lips are a different question — see lip reduction.

Does hyaluronidase dissolve Radiesse or Sculptra?

No. Hyaluronidase only works on hyaluronic acid. It does not dissolve Radiesse (calcium hydroxylapatite, CaHA), Sculptra (poly-L-lactic acid, PLLA) or permanent fillers such as silicone, PMMA or paraffin, which our clinic does not use. This is why it matters to know which product was injected.

What are the warning signs of a filler emergency?

Severe or increasing pain, or skin that turns pale, white, dusky or mottled, or feels cold after filler, can be signs of vascular occlusion — a blood vessel blocked by filler. Very rarely, vision changes occur. Contact the clinic immediately; if you are far from Istanbul, also seek urgent local medical care.
