Dissolving filler with hyaluronidase: facts vs myths (UK)
What hyaluronidase can and cannot do, risks, timelines, and why it is a medical procedure—not a ‘reset button’ you order casually. Doctor-led context for London & Birmingham patients.
TL;DR
- Hyaluronidase is an enzyme used by qualified clinicians to break down hyaluronic-acid (HA) filler in many situations—it is a medical intervention with its own risks and limitations.
- It is not a guaranteed “instant perfect face” tool; multiple sessions, swelling, and judgement about how much tissue to treat are common.
- If you have filler concerns after treatment, contact the treating clinic urgently if you have skin colour change, severe pain, or blistering.
What hyaluronidase is (plain English)
Many dermal fillers used in the UK are HA gels. Hyaluronidase speeds breakdown of HA. It is used when clinically appropriate—for example complications, unacceptable aesthetic outcome after review, or misplacement concerns—always as a medical decision.
It does not dissolve non-HA products. If you do not know what was injected, the pathway starts with records and history, not guesses.
Myths that cause harm
“It’s always safe because it’s an enzyme”
No. Allergic reaction, tissue changes, over-correction, and unpredictable outcomes are discussed in consent in competent practice.
“One session fixes everything”
Sometimes yes; sometimes partial dissolution is intended; sometimes repeat review is needed.
“I can dissolve at home / abroad and start again”
Self-directed “dissolving” is dangerous. This belongs in a clinical setting with emergency support if needed.
What a doctor-led pathway should include
- Indication clarity — what problem are we treating (lump, migration concern, vascular emergency protocol, aesthetic reset)?
- Consent — including risks such as allergy, skin changes, and asymmetry during healing.
- Follow-up — timing for reassessment and any further treatment planning.
For how we think about fillers more broadly, see dermal fillers.
Timelines patients should expect
You may see change quickly, but swelling and skin reaction can distort the picture for days. Your clinician should tell you when to judge and when to return.
Relationship to lip and under-eye filler
- Lips: context in first lip filler visit.
- Under eyes: under-eye filler guide.
Frequently asked questions
Will my face look hollow after dissolving?
It can look temporarily deflated if a lot of volume is removed; staged planning matters.
Can hyaluronidase affect natural tissue?
Discussion of off-target effects belongs in consent with your clinician.
Is dissolving painful?
Discomfort varies; anaesthetic approaches vary by clinic policy.
How much does it cost?
Pricing depends on indication, product volume, and follow-up—check our price list and confirm in consultation.
Do you offer this at Aesthetics by KK?
If clinically appropriate within our governance—book for assessment.
