Hyaluronic acid filler dissolves; Sculptra, Ellansé, Radiesse and fat grafts do not; HIFU and threads change the layers beneath the skin. Dr Sin Yong scans with ultrasound before anything is corrected, because correcting the wrong layer is how a second problem starts.
Ultrasound shows the product, its depth and whether it is one pocket or several.

Non-dissolvable lumps, overfilled grafts and fat pads are reduced with the Sculpting mode of Time Freeze Laser LCLR®, without an incision.
Suitability is decided at an in-person assessment. No prices are quoted on this page; fees are given in writing after the assessment. Images and video are illustrative, not patients.
When an aesthetic treatment goes wrong, the first question is what was done and where it now sits: hyaluronic acid filler that can usually be dissolved, a collagen stimulator that cannot, heat or ultrasound that has changed the fat under the skin, or a thread beneath the surface. Each guide below covers one treatment: the problems it can cause, what the assessment checks first, and the options, including waiting.
Key facts
Hyaluronic acid filler
Can usually be dissolved with hyaluronidase, after the filler has been located with ultrasound
Sculptra, Ellansé, Radiesse, Juvelook
Do not dissolve. Lumps are scanned first; Dr Sin Yong treats them with the Sculpting mode of Time Freeze Laser LCLR®, without an incision
HIFU and radiofrequency
Fat loss, burns or nerve weakness, assessed by which layer was affected
Thread lift
Dimpling, a visible or palpable thread, asymmetry or infection, each with its own first step
Fat grafting
Excess or lumpy graft, mapped with ultrasound before anything is reduced
Urgent after filler
Pale, dusky or mottled skin or worsening pain needs the doctor who injected you, or A&E, now. A change in vision: call 995
Correction starts with finding out what was done. The product or device, the amount, the date and the clinic decide what is possible, so bring whatever you know, including photographs from before the treatment.
Where filler or a collagen stimulator is suspected, Dr Sin Yong scans the area with ultrasound to see how deep the product sits, how much there is and whether it is one pocket or several. After HIFU, radiofrequency or threads, the examination looks at skin thickness, the fat beneath it and how the face moves. Some early problems settle as swelling goes down, so waiting is one of the options discussed.

Is surgery the only way to remove a lump?
Cutting a lump out leaves a scar and can injure the nerves that move the face, so it is kept for what cannot be managed another way. Hyaluronic acid lumps are dissolved with hyaluronidase placed into the filler seen on the scan. Lumps from Sculptra, Ellansé, Radiesse or Juvelook do not dissolve; Dr Sin Yong treats these with the Sculpting mode of Time Freeze Laser LCLR®, without an incision. The guide to hard lumps after filler explains how the product type is identified.

When is it urgent?
After filler, skin that turns pale, dusky or mottled, or pain that is getting worse, can mean an artery is blocked. That needs the doctor who injected you, or A&E, now; a change in vision or eye pain means calling 995. The warning signs of vascular occlusion and complication care after treatment set out what to do. Fever, spreading redness or pus after a thread lift or filler also needs prompt review.
Frequently Asked Questions
It depends on what was done, where it sits and how long ago, and sometimes the right choice is to leave it alone. Hyaluronic acid filler can usually be dissolved; collagen stimulators, fat grafts, heat injury and threads each need a different approach, decided at an in-person assessment.
For an urgent sign after filler, such as pale or dusky skin or worsening pain, go back to the doctor who injected you, or to A&E, now. For a problem that is not urgent, the original clinic can tell you exactly what was used, and a second opinion is reasonable if you are unsure about the plan offered.
Some early problems settle as swelling goes down, so a non-urgent correction is often planned after the first few weeks. Urgent signs are never left to wait. The guide for your treatment explains which changes are expected and which need review.
The name and amount of the product, if known, the date and the clinic, and photographs from before and after the treatment. If you are not sure what was used, say so: the ultrasound scan and the examination help to work it out.
