Filler migration
Recently, you have been hearing more and more about filler migration. This is not a new phenomenon, but with the global increase in filler use and new scientific findings, it is something that is getting more and more attention.
In this article, we discuss filler migration: what it is, its causes and, most importantly, whether we can prevent filler migration.
What is filler migration?
Filler migration refers to the unwanted movement of the filler from the injection site to surrounding or more distant tissues. This can cause distortion, lumps and volume in unwanted areas but can also cause pain.
In 2016, an interesting case² of filler migration was investigated of a 33-year-old woman where hyaluronic acid filler moved from the nose to the forehead. Now we see filler migration mostly at the lips. Especially when too much filler was injected or the wrong type of filler was used. What are the main causes of filler migration.
Causes of filler migration
The exact mechanisms behind filler migration have not yet been fully elucidated, but we do know that the elements below contribute to filler migration:
- Anatomical structures: muscle movements and vascular networks can contribute to the movement of filler.
- Injection technique: improper injection technique and/or injection site may increase the risk of migration.
- Physical properties of the filler: the viscosity and cohesiveness of the filler can affect its stability after injection.

How can you prevent filler migration?
Fortunately, at Ivy clinics, we see very few cases of filler migration. We do everything we can to prevent filler migration and other filler complications. The cases we do see are mostly in people who have been overly treated with fillers elsewhere. We believe it is important to deliver natural results and therefore will never over-treat our clients with filler. Our doctors have a deep understanding of facial anatomy, attend specialized training in injection techniques and choose fillers appropriate to the indication to prevent filler migration.
Treatment of filler migration
In the case of migration, it is often possible to gradually dissolve the filler with hyaluronidase. Depending on the amount of filler to be dissolved, we do this in one to three sessions. By the way, we use hyaluronidase only if it is really necessary. The drug is not meant to be used without indication. In stubborn cases, surgical excision of the filler may be necessary.
In the Netherlands, we have a special filler complication consultation at Erasmus MC in Rotterdam. Here we have doctors and dermatologists who specialize in treating complex filler complications.
Frequently asked questions about filler migration
How long does it take for filler to migrate?
The timeline of filler migration varies, but may occur gradually in the first weeks to months after treatment.
Where does filler migrate fastest?
Migration of filler is most commonly observed in dynamic areas, such as the lips. Therefore, it is important not to over-inject and to use a flexible type of hyaluronic acid filler in the lips.
Which filler does not migrate?
Calcium hydroxylapatite(Radiesse) is said not to migrate. Research does show that this type of filler is more likely to cause nodules.
How can you prevent filler migration?
Avoid pressing or massaging the treated area. We also recommend avoiding activities that increase pressure on the injection site, such as strenuous exercise or wearing tight headgear, for 24 to 48 hours after treatment. In this, follow the advice of your treating physician.
