Quick answer: found a lump — now what?
- In the first 1–2 weeks, most "lumps" are swelling and settle on their own — don't judge early
- Don't massage or press it yourself unless the injecting doctor told you to, with a technique
- A lump that persists past the swelling window deserves a review visit, not a wait-and-hope
- If the filler was genuine HA, a doctor can dissolve it with hyaluronidase — often in one or two visits
- Severe pain, white or dusky skin, or vision changes are a different category: urgent, today
Normal swelling vs a real lump
Right after injection, the area contains filler plus swelling plus sometimes a small bruise — which is why everything feels lumpy for days and why lips and under-eyes look uneven at first. Normal post-filler firmness is diffuse, softens week by week, and looks better in the mirror as the swelling leaves.
A real lump behaves differently: it is distinct rather than diffuse, it persists after the swelling has clearly settled, and it may be visible in certain light or expressions. That still doesn't make it dangerous — but it makes it worth showing to the doctor who injected it, because the fix depends on the cause.
Why filler lumps happen
- Superficial placement — filler set too close to the surface shows as a bump or, under thin skin, a bluish tint (the Tyndall effect)
- Too much product — overfilling an area faster than the tissue can accommodate it
- Migration — filler drifting from where it was placed, common around the lips over time
- Product choice — a filler too firm for the area, such as a thick gel in the under-eye
- Delayed nodules — weeks or months later, the body can react to filler with firm nodules; some are inflammatory and need treatment beyond dissolving
- Infection — a red, hot, painful or growing lump is not a cosmetic issue; it needs medical attention
Notice what most of these have in common: technique and product choice. Lumps are far less about bad luck than about who injected what, where — which is why prevention is mostly clinic choice.
What hyaluronidase is and how dissolving works
Hyaluronidase is an enzyme that breaks down hyaluronic acid — the material HA fillers are made of. Injected into a lump, it dissolves the filler, with visible change often within a day or two. The doctor controls how much dissolves: a small dose can soften a lump while keeping most of the result, or a larger dose can clear the area to restart cleanly. Some people need a second pass, and dissolved areas can be refilled later once things settle.
Three practical notes. First, hyaluronidase works only on HA fillers — it does nothing for biostimulators, silicone or mystery products, which is exactly why we keep repeating "confirm it's HA" before you inject. Second, allergic reactions to the enzyme are possible, so it belongs in a doctor's hands, not a salon's. Third, in a suspected vascular occlusion, hyaluronidase is the emergency treatment and timing matters — which is why "do you stock it?" is on our pre-injection checklist.
When a lump needs urgent care
Skip the review queue and contact the clinic — or urgent care — immediately if a lump comes with:
- Severe or increasing pain out of proportion to the injection
- Skin turning white, grey, dusky or mottled near the area
- Blistering, darkening or skin breaking down
- Vision changes of any kind
- Fever, spreading redness, heat or pus — signs of infection
These point to blood-supply problems or infection, not cosmetic imperfection — the full list is in our guide to filler risks and warning signs.
What not to do
- Don't massage aggressively on your own — you can spread filler into the wrong plane or irritate the tissue
- Don't let a non-doctor "fix" it with more filler on top
- Don't accept dissolving from someone who can't name the enzyme, the dose, or the plan
- Don't wait months on a painful, red or growing lump — that is not a settling problem
- Don't panic-dissolve in week one — much of what worries people early is swelling that resolves by itself
The bottom line
Most filler lumps are either early swelling that needs time or technique problems that hyaluronidase can undo — provided the filler was genuine HA. Give swelling its two weeks, show persistent lumps to the doctor, treat pain, colour change or vision symptoms as emergencies, and remember the quiet lesson underneath all of this: the dissolvability you may one day depend on is only real if the product in the syringe was real.
