There is a ridge above your lip that was not there before. That firm little edge, or the way your top lip now spills past its own outline, is most often migrated lip filler: product that has moved past where it was placed. It is one of the most common reasons patients come to me asking about dissolving.
Most people want two questions answered: what happened, and whether correcting it will leave them looking deflated. Done in small, staged amounts, it rarely does. I am Debra Jaliman, MD, a board-certified dermatologist in New York City with more than 30 years in practice, and correcting filler placed elsewhere is a regular part of my work.
Is it swelling, or has my filler moved?
Start by working out what you are actually looking at. You can usually tell the difference yourself, at the mirror, in about a minute.
Swelling
Filler that has moved
Too much filler
Where it sits
The body of the lip
Above the natural edge, between lip and nose
The body of the lip
How it feels
Soft and puffy
Firmer, a ridge you can run a finger along
Heavy rather than ridged
When it appeared
Within hours, settles in days
Weeks or months later
Straight after treatment
What it means
Normal healing
Product has travelled
The right place, just more than you needed
What I do
Confirm it will settle
Small, staged hyaluronidase to soften the ridge and restore your lip line
Reduce a little, or wait for it to break down
In my experience, anything still there after a week is unlikely to be swelling.
A firm spot that shows up late is usually movement, though it can also be a nodule, worth having looked at either way. Lumps still present after four weeks, asymmetry that has not evened out, and persistent puffiness are all worth a visit. If your lips are still settling from a recent appointment, our day-by-day guide to lip filler swelling has the normal timeline.
When to call the same day
Almost nothing about migrated filler is urgent. One thing is. If you have sudden severe pain, skin that turns white or blotchy, or a dusky patch around the lips or nose, call immediately, whether or not your treatment was with me. That pattern can mean filler has blocked a blood vessel: rare, but a genuine emergency, treated with high-dose hyaluronidase straight away. It is a different situation from the planned correction below.
Why lips in particular
Migration has almost nothing to do with your aftercare. Lips never stop moving, and there is nothing firm inside to hold product in place. Filler placed too shallow or too close to the edge has an easy path outward, and layering new filler over old that has not broken down makes it worse. Those are decisions made at an earlier appointment, not things you did.
What correcting a ridge actually involves
Correction uses an enzyme called hyaluronidase. Most lip fillers are a gel made of hyaluronic acid, a substance your body already produces, and hyaluronidase is the natural enzyme that breaks it down. A few small injections placed where the stray filler sits.
This is not an undo button. The enzyme acts on both the injected filler and your body's own hyaluronic acid, so it cannot pick out the product and leave the rest untouched. A 2026 paper in the Aesthetic Surgery Journal makes the case for calling this modifying the filler rather than dissolving it: what changes is the whole filler-and-tissue complex, with less swelling, a looser gel and more pliable tissue. Your lips can look completely corrected while a small amount of filler is still there on imaging. It is the look we are after, not an empty lip.
Hyaluronidase is a prescription medication, not something to source online or let an untrained injector use on you. Too much, or in the wrong plane, dissolves filler you wanted to keep and can leave a hollow that takes months to recover.
I go through your allergy history first. Some forms of hyaluronidase are made from animal protein, while Hylenex is a recombinant human enzyme produced in cell culture. Allergic reactions occur in fewer than 0.1% of patients, but I ask, and in my practice I skin test anyone with a history of allergies.
How much gets used, and why I do it in stages
There is no set amount. I decide at the visit, because no two lips are the same: how much is in there, how deep it sits, how firm the original product was, and how much you want gone.
If a ridge above your lip line is the issue, I soften that. I inject conservatively, watch how it responds over the following days, and add a second small treatment only if needed. One session is often enough for a ridge, though larger volumes and stubborn nodules can take more.
Why not do it all at once? The enzyme can affect nearby filler you wanted to keep, and once it acts, you cannot put that volume back the same day.
What will my lips look like afterward?
In most cases, your lips look like your lips, minus the ridge. Most patients notice softening within a day or two. For the first 48 hours you may have some swelling from the injections themselves, so the lip can look softer or flat. That settles on its own, and by one to two weeks your lip line is usually back where it belongs.
Be ready for one thing: your natural lips will look thinner than your filled lips did. That is not the correction going wrong, it is your starting point.
The reason the area does not usually stay hollow is not that your body rushes to refill it. The hyaluronic acid in your skin has a half-life of about one day, turning over constantly, but that everyday turnover is not thought to speed up to improve a sudden loss. What protects your shape is the approach: treating only the ridge, in small amounts, and leaving what you wanted to keep where it is.
After hyaluronidase, most people should wait at least a week before new filler. That gives the enzyme time to clear and the tissue time to settle, so I can see what your lips look like on their own. Going straight back in means layering filler over unsettled tissue, which is how the ridge started in the first place.
Who should fix it, and what the first visit looks like
Ask three things before you book anywhere. Will they examine the lip before quoting? Will they stage the correction rather than promise a single reversal? Will the physician do it themselves?
Here it is a 30-minute consultation, and I do not reach for a syringe. I look at where the filler sits, tell you whether it is movement, swelling, or simply too much product, and walk you through each step first. Bring your treatment history, and mention any medications and supplements: aspirin, ibuprofen, fish oil and vitamin E all thin the blood and are worth stopping about a week beforehand if your own doctor agrees.
Correction work is a steady part of my practice, most often a ridge that showed up after dermal filler done elsewhere. Because I am also a medical dermatologist, that same visit can cover anything else you have been meaning to have looked at, whether it is a mole that has changed or a spot you are not sure about. I do thorough skin cancer screenings and many patients combine the two. See our explainer on hyaluronidase, our piece on why filler results vary by injector, and before and after results.
Lip augmentation reached 1,449,565 procedures in the United States in 2024, so a ridge after lip filler is common and usually fixable. Book a consultation and we will start by finding out what is actually there.
FAQs
Will my lips look exactly like they did before I ever had filler?
Usually close to it. Two caveats: a small amount of filler can remain even when the shape looks fully corrected, and if a lot of time has passed, or there was infection or inflammation along the way, your lips will have changed on their own.
How much does it cost to dissolve or correct lip filler?
It depends on how much filler is there, how deep it sits, and whether it takes one session or two, so I give you the figure once I have examined your lip rather than over the phone. The consultation is $250, credited toward whatever you decide to do.
Is dissolving lip filler safe?
In the hands of a board-certified dermatologist it is generally safe. Swelling, bruising and redness are common and short-lived, and true allergic reactions are rare. The risks come from too much enzyme, injecting the wrong plane, or an untrained injector.
Does correcting migrated filler leave your lips deflated?
Rarely, when the goal is shape rather than removing everything. Small, staged amounts are what protect the shape you want to keep.
