Dermal filler dissolving is the process of breaking down and removing hyaluronic acid (HA)-based dermal fillers using an enzyme called hyaluronidase (commonly known as Hyalase® in the UK). Hyaluronidase works by breaking down the hyaluronic acid within the filler, allowing the body to naturally absorb and eliminate it.

While dermal fillers are generally very safe when administered by appropriately trained professionals, there are occasions where dissolving treatment may be necessary — either for urgent medical reasons or simply because the aesthetic result is no longer desired.

Important: Hyaluronidase is Prescription-OnlyHyaluronidase is classified as a prescription-only medicine (POM) in the UK. It must be prescribed and administered by a qualified medical prescriber — such as a doctor, dentist, nurse prescriber, or pharmacist prescriber. This is particularly significant because non-medical practitioners who legally inject fillers cannot independently prescribe or administer hyaluronidase if a serious complication occurs.

Why might dermal fillers need to be dissolved?

Filler dissolving may be performed for both urgent medical reasons and elective aesthetic reasons:

Medical Reasons (Urgent)

  • Vascular Occlusion — filler blocks a blood vessel, risking tissue necrosis or in rare cases blindness. Requires immediate hyaluronidase.
  • Infection — dissolving the product may help the area heal more effectively alongside medical treatment.
  • Allergic Reactions — swelling, redness, or inflammation in response to filler products.
  • Nodules or Lumps — visible or palpable lumps caused by inflammatory reactions or product placement.
  • Filler Migration — filler has moved from the original treatment area causing puffiness or asymmetry.

Aesthetic Reasons (Elective)

  • Overfilled Appearance — too much filler creating an overly full or unnatural "pillow face" result.
  • Uneven or Asymmetrical Results — to rebalance the face before further correction.
  • Change in Personal Preference — the client prefers a more natural appearance or no filler.
  • Preparation for Other Treatments — old filler may need removing before surgery or other procedures.

How does filler dissolving work?

1

Consultation and Assessment

A full consultation is essential before treatment. Your practitioner will assess the area, confirm the type of filler used, discuss risks and expectations, and check for any allergies or contraindications — including allergy to hyaluronidase itself.

2

Prescription of Hyaluronidase

Because hyaluronidase is a prescription-only medicine, it must be prescribed by a qualified medical prescriber. This is one reason why choosing a medically qualified practitioner from the outset is so important.

3

Treatment Procedure

The hyaluronidase is injected directly into the area containing the filler. The enzyme begins working almost immediately, although full results are usually seen over 24–48 hours.

4

Aftercare and Follow-Up

Some swelling, redness, or bruising is common after treatment. Follow-up appointments may be needed to assess whether further dissolving is required or whether retreatment is appropriate.

The regulatory issue this highlights

This creates a significant safety concern within the UK aesthetics industry. Dermal fillers are not currently prescription-only — meaning almost anyone can legally administer them. However, hyaluronidase, which is essential for managing serious filler complications such as vascular occlusion, is prescription-only. This means a non-medically qualified practitioner who legally injects fillers may be completely unable to independently manage a serious complication.

For this reason, organisations such as Save Face, the Joint Council for Cosmetic Practitioners (JCCP), and the British College of Aesthetic Medicine (BCAM) strongly advocate that injectable aesthetic treatments should only be carried out by appropriately trained medical professionals.

Why choosing a qualified practitioner matters

The ability to recognise and treat complications quickly is one of the most important aspects of safe aesthetic practice. In the event of a vascular occlusion, prompt administration of hyaluronidase can dramatically reduce the risk of permanent tissue damage. A safe practitioner should not only know how to create beautiful results — but also how to manage complications quickly, professionally, and safely if they arise.

Filler dissolving plays a vital role in both aesthetic correction and emergency complication management. While most dermal filler treatments are straightforward and successful, complications can and do occur — which is why choosing a qualified, medically trained practitioner is so important. At Radiant, patient safety, transparency, and ethical practice are always our highest priorities.
