Nasolabial Filler That Sank Again in a Week or Two: Migration & Ultrasound-Guided Removal

"Doctor, did I just waste this? It really was flat for the first week, and now it's sunk right back." I hear this almost every week.

Usually the next question is the crucial one: does that mean it was absorbed? Or that it was never placed well? There is actually a third possibility, and it's the most common one — yet many people are never told about it: it may simply have migrated, drifting off to the side. Let me take these three apart and make them clear.

Swelling, absorption, migration — how do you tell them apart? Start with the timeline

The changes after an injection follow a rough timeline, and checking against it lets you judge most of it yourself.

For the first three days or so it looks fullest, and a large part of that is swelling, not the filler itself. So if it feels "wow, so flat" right after, don't get too excited — there is edema in there.

Around one to two weeks the swelling has mostly gone down, and only then are you seeing the filler as it "settles." If it's reasonably even and symmetrical at this stage, there's usually no problem.

What to really watch is what comes after. If the settling period has passed and the fold is slowly sinking again — or even looks odder than before you started — that usually can't be explained by "still swollen." For HA to be metabolized by the body takes months, not a week or two. So sinking again within a week or two looks more like migration than absorption. The market is very used to brushing it off with "let it settle, give it time," but if you're past the settling period and still sinking, waiting is just delay.

Where did the filler go? The three most common destinations

So where does it migrate to? In my experience, nasolabial filler travels most often in three directions.

One is upward, above the fold, toward the apple cheek. One is outward and down, into the jowl. And one is downward, toward the marionette lines — the two creases below the corners of the mouth.

It travels this way because this whole area moves all day — smiling, talking, chewing all push the filler toward wherever there is less resistance. Soft HA placed in a spot that moves like this was never going to sit still.

Your new jowl or puffiness may be old filler that has drifted

Here is something many people have never been warned about.

Some come to me with a complaint that isn't the nasolabial fold at all — "I don't know why my jowl got thicker lately," "there's a puffiness under my eyes," "my side profile looks more saggy." Ask a little, and they had filler in the nasolabial fold or cheek years ago. Look with ultrasound, and that new thing that appeared is often exactly the filler placed back then, having drifted and piled up in this new spot.

So if you've had filler and then some "unrelated-looking" new problem shows up, don't rush to open a new treatment to deal with it. First consider whether it might be old material that has drifted. This ties directly into the piece on the soft-versus-firm dilemma of nasolabial filler: migration is one of the core problems of this fold.

Why does topping up keep making it worse?

Once you understand migration, that "worse the more you fill" loop makes sense.

The fold sinks again, and the instinct is "not enough, add more." But the problem isn't the amount — what was placed earlier has already drifted off. Adding now just lays another layer over material that has already migrated and accumulated. In the end the fold itself isn't genuinely better, while the jowl is thicker, the marionette lines more obvious, and the whole lower face heavier — what people call a puffy, doughy result.

Put another way, endlessly adding into the groove feeds the migration and accumulation rather than solving it.

Can migrated filler be "moved back"?

Many ask whether it can just be pushed back, pressed into place. Honestly, it isn't that simple. Filler that has already migrated — or been walled off by the body — usually can't be pushed back by hand or hard massage, and doing so risks making things messier and catching a vessel.

The more realistic approach is to find it and remove it first, bring the area back to a clean state, and then decide again whether and how to treat it. That's a different line of thinking from "moving it back" — rather than wrestling drifted material back into place, it's better to clear it out first.

Single-port removal under ultrasound guidance

So how is it removed? My approach is minimally invasive removal under ultrasound guidance.

The point of ultrasound is to see clearly before doing anything: which layer the material has drifted into, where it is caught, and how close it runs to branches of the facial artery. Once that's clear, a small port goes in, watching the real-time image, taking out what should come out a little at a time while avoiding vessels.

To be honest, removal usually reaches about eighty or ninety percent, not a hundred, and it varies from person to person — especially when it has drifted for years over a wider area. But the point is that it puts what comes next on a clean footing, rather than laying another layer over a pile of drifted old material. If what you feel is a hard ridge and you want to know first whether that's normal or a complication, see the piece on feeling a hard ridge in the nasolabial fold.

Back to "did I just waste this?"

I usually answer like this: not necessarily wasted, but if you're past the settling period and still sinking, that's most likely migration — not too little, and not still swelling. In that case, adding another round will very likely just thicken the jowl.

The better order is to look clearly with ultrasound at the current state inside, confirm where it drifted to, and then decide whether to remove it and start over. The problem with a nasolabial fold, much of the time, isn't whether it was filled enough — it's what has accumulated in that groove over these years.

If you can't tell whether yours is swelling, absorption, or migration, book an ultrasound assessment — we'll look clearly first, then decide the next step together. You can also start from the nasolabial revision area overview to see other related approaches.
