Filler Dissolving London. Hyaluronidase Filler Removal Explained
Hyaluronic acid filler is dissolved using an enzyme called hyaluronidase, which breaks down the filler so the body absorbs it, with visible change often within 24 to 48 hours. It is used for migrated, lumpy or overfilled results, and urgently for complications such as vascular occlusion. Hyaluronidase is a prescription-only medicine in the UK, and non-medical practitioners cannot legally hold or inject it, which is why this treatment should be doctor-led.
Key points
Hyaluronidase breaks down hyaluronic acid filler so the body reabsorbs it, with visible improvement typically within 24 to 48 hours and the final result clearer after swelling settles.
It is a prescription-only medicine in the UK, and its use for dissolving cosmetic filler is off-label, requiring an individual assessment and informed consent.
Non-medical practitioners cannot legally hold or inject hyaluronidase, which means a non-medic who injects filler cannot treat the most serious complication of it.
It only dissolves hyaluronic acid fillers, not permanent or semi-permanent products such as poly-L-lactic acid, calcium hydroxylapatite or PMMA.

How does filler dissolving work
Most modern dermal fillers are made from hyaluronic acid, a sugar molecule that occurs naturally in the skin. Hyaluronidase is an enzyme that breaks the bonds within hyaluronic acid, reducing the structure and volume of the filler gel so that it disperses through the tissue and is absorbed by the body. It is delivered as a series of small injections placed into the area where the filler sits.
Change often begins within hours and is usually visible within 24 to 48 hours, although swelling immediately after treatment can make the final result difficult to judge for several days. The dose depends on the type of filler, how much is present, how densely cross-linked it is and the outcome you want, which is a clinical judgement rather than a fixed recipe. Dense, heavily cross-linked products can need higher doses or more than one session, and your doctor will plan for that rather than promise a single-visit fix.
Why people have filler dissolved
The reasons fall into two groups. The first is dissatisfaction with the result, including filler that has migrated beyond where it was placed, lumps or nodules, asymmetry, an overfilled look, or under-eye filler that has become puffy or blue-tinged. Lip filler migration is one of the most common reasons people seek dissolving, and it often develops gradually over repeated treatments rather than after a single one.
The second group is complications, and these can be urgent. Vascular occlusion, where filler compresses or enters a blood vessel and restricts blood flow, is a medical emergency because it can lead to tissue death and, in rare cases, visual loss. Prompt hyaluronidase is the treatment. This is exactly why who injected your filler matters, and why a growing number of people also choose to dissolve simply to reset and start again with a more conservative plan.

Why filler dissolving must be doctor-led
This is the part patients are rarely told. Hyaluronidase is a prescription-only medicine in the UK, which means it must be prescribed for you individually by an appropriate prescriber following a face-to-face assessment, and remote prescribing of injectable cosmetic medicines is not permitted. Non-medical practitioners cannot legally hold or inject it.
The implication is significant. A non-medic who injects your filler cannot lawfully treat the most serious complication of that filler, and would need to send you elsewhere at exactly the moment when hours matter. It is also worth knowing that using hyaluronidase to dissolve cosmetic filler is off-label, since that is not among its authorised indications, which is entirely legitimate when a prescriber makes an individual assessment and explains the reasoning, benefits, uncertainties and alternatives before taking consent. Industry bodies including the JCCP and Save Face recommend that injectables are carried out by trained medical professionals for precisely these reasons. As our doctors put it, "the person who injects you should be the person able to fix it."
What to expect and what the risks are
Treatment is quick, and most people find it comparable to having filler placed. Expect swelling, redness and tenderness afterwards, and bruising is common, particularly around the lips and eyes. The area will often look worse before it looks better, and it is sensible to allow a couple of weeks before judging the outcome or planning any further treatment.
The main risks are an allergic reaction, which is rare but is why your medical history is reviewed carefully and any history of severe allergy disclosed, and the fact that hyaluronidase can temporarily affect some of your own naturally occurring hyaluronic acid in the area, which replenishes over time. Results are not always complete in one session, especially with dense products or older filler. And critically, hyaluronidase does not dissolve non-hyaluronic-acid fillers such as poly-L-lactic acid, calcium hydroxylapatite or permanent products, so establishing what was injected into you is part of the assessment.
Why doctor-led care matters at The London PRP Clinic by The Wellness
Every treatment at our clinic is performed by GMC-registered doctors, which for filler dissolving is not a preference but a legal and clinical requirement. Our doctors take a full history, establish as far as possible what product was used and when, examine the area, explain that the use is off-label and what that means, and take proper informed consent before treating.
We also plan what comes next, because dissolving is rarely the end of the story. Many people want a considered plan afterwards, and our regenerative options including polynucleotides and PRP focus on skin quality rather than added volume, which suits patients who have decided they were overfilled. Across our work we report more than 187 five-star reviews. We will also tell you honestly when dissolving is not the right answer, or when waiting is.

What filler dissolving costs in London
Doctor-led aesthetic care in central London sits at the top of the UK market, and flagship Harley Street and Mayfair clinics price at the higher end. Cost for dissolving depends on the area, how much filler is present and whether more than one session is likely to be needed, so a single headline figure is rarely accurate.
At The London PRP Clinic by The Wellness, treatment is doctor-led and priced below those flagship rates, with your assessment and the exact figure confirmed when you enquire. If you are comparing quotes, ask who will perform the treatment and whether they are a prescriber, since that is the question that determines whether they can lawfully treat you at all.

Frequently asked questions about filler dissolving
How quickly does filler dissolving work?
Change often begins within hours and is usually visible within 24 to 48 hours, though swelling can make the final result difficult to judge for several days. Dense fillers may need more than one session.
Can anyone dissolve filler?
No. Hyaluronidase is a prescription-only medicine in the UK and non-medical practitioners cannot legally hold or inject it. It must be prescribed following a face-to-face assessment by an appropriate prescriber.
Does hyaluronidase dissolve all fillers?
No. It breaks down hyaluronic acid fillers only. Products such as poly-L-lactic acid, calcium hydroxylapatite and permanent fillers are not dissolved by it, so identifying what was injected matters.
Does dissolving filler damage your skin?
It can temporarily affect some of your own naturally occurring hyaluronic acid in the treated area, which replenishes over time. Swelling and bruising are common short-term effects.
Why is dissolving used as an emergency treatment?
Because vascular occlusion, where filler restricts blood flow, is a medical emergency that can cause tissue damage and, rarely, visual loss. Prompt hyaluronidase is the treatment, which is why medical availability matters.
