Filler dissolving and correction

Filler dissolving with hyaluronidase to correct lumps, migration and bluish tint

HA filler that has lumped, migrated, swollen into pockets, turned bluish under the eyes or been over-injected can be corrected with the enzyme hyaluronidase. An ultrasound scan first shows the position, amount and type of the existing product, and the doctor then dissolves only the problem areas.

Common filler problems and why they happen

With HA filler, most problems come not from the product itself but from choosing the wrong product for the area, injecting too superficially, injecting large amounts repeatedly or using unregistered products. The results include lumps you can feel or see, filler migrating from the nose into the brow area or from the lips above the lip border, slow puffy swelling under the eyes months after injection, blue-grey patches from the Tyndall effect, an over-filled face that looks unnatural after years of accumulation and, less commonly but importantly, delayed red inflamed nodules after a viral infection or dental procedure. If the product is HA, all of these can be dissolved. Permanent substances such as liquid silicone or PMMA need a different approach.

The clinic's approach to correction

History of the previous injectionWhere, when, which brand, how many cc, and whether you have a certificate or photograph of the box. This tells us whether it is likely to be HA or something else
High-frequency ultrasound scanShows the position, depth, size and nature of the lump. HA appears as a distinct dark pocket, while permanent substances give a different echo. It also shows nearby vessels so the dissolving can be planned away from them
Hyaluronidase allergy testA small test dose beneath the skin of the arm, observed for 20–30 minutes, except in a vascular emergency where immediate injection is needed
Targeted dissolving under ultrasoundThe enzyme is injected directly into the filler lump, the dose depending on its size and firmness, usually 30–150 units per area, with gentle massage to spread it. Lumps usually flatten within 24–48 hours
Review at 1–2 weeksRepeat ultrasound; if any remains, more can be dissolved. If you want new filler, wait 2–4 weeks for the enzyme to wear off and the tissue to settle

Problems and solutions

ProblemCommon causeApproach
Palpable lump / uneven surfaceInjected too superficially, or a product too firm for the areaDissolve only the lump with a small dose, keeping the good portion
Migrated fillerLarge amounts, injection in a mobile layer, or pressing and massaging too soonDissolve the migrated portion and re-inject in the correct layer after 2–4 weeks
Puffy under-eyes / bluish tintPlaced superficially, a product with high water uptake, or skin that retains fluidDissolve all the under-eye filler, wait 4 weeks, then reassess whether to re-inject or use another method
Over-filled, unnatural faceYears of accumulation; under-eye and cheek filler breaks down more slowly than expectedDissolve partially in 2–3 stages so the face can adjust, rather than all at once to avoid sudden hollowing
Red, inflamed nodules long after injectionAn immune reaction to the product, or bacteria in a biofilmAntibiotics, filler dissolving and anti-inflammatory medication as the doctor prescribes. A culture may be needed
Permanent / unknown substanceLiquid silicone, PMMA or unregistered productsHyaluronidase does not help. Anti-inflammatory injections are assessed, or referral to the surgical team
Signs that need a doctor immediately

After filler anywhere, if you have severe pain out of proportion to the injection, skin turning pale white or mottled dark purple, map-like grey patches, blisters, blurred or lost vision, or inability to speak or move one side of the face, these are signs of vascular occlusion, and the filler must be dissolved within the first hours. Do not wait for an appointment: call or come to the clinic immediately during opening hours, and go to a hospital emergency department outside them. The clinic provides emergency dissolving even if the filler was injected elsewhere

Worth knowing about hyaluronidase

  • It is an enzyme that digests only HA. It does not dissolve other substances and does not permanently affect the skin's natural HA, which the body rebuilds within 1–2 days
  • Allergy is possible but rare. People allergic to bee or wasp venom have a higher chance and must tell the doctor
  • Long-standing lumps or very firm products may need more than one session
  • After dissolving, the area may look more hollow than before the filler for 1–2 weeks as swelling settles and tissue adjusts
  • Filler that migrated to the lips or brow years ago can still be dissolved, but skin that has been stretched may not return to its original firmness

Frequently Asked Questions

When can I have new filler after dissolving?

Generally 2–4 weeks afterwards, so the enzyme has worn off and the tissue has settled. The doctor confirms with ultrasound before re-injecting.

I do not know what was injected before. Can you tell?

Ultrasound distinguishes HA from other substances in most cases. If it is HA, a small test dose of enzyme is injected to see whether the lump flattens. If it does not, a permanent substance is likely.

Will my face look more hollow after dissolving?

For the first 1–2 weeks it may look slightly more hollow than before the filler, as swelling subsides and previously stretched skin adjusts. Most people return close to their original appearance within a month. Where a lot has accumulated, the clinic dissolves in stages for this reason.

My filler was done elsewhere. Will you correct it?

Yes, both when you are unhappy with the result and when there is a complication. Please bring your records or a photograph of the original product box if you have them.
