Hyaluronic acid is today one of the most used products in aesthetic-oriented medicine to reshape facial contours in a non-invasive way. When injected into the chin, it allows projection, structuring, or harmonization of the lower third of the face. But a question often arises : can the product migrate after injection ?
It is legitimate to wonder about the stability of a substance injected under the skin, especially in a mobile and expressive area like the chin. Here is a clear answer based on scientific data, clinical practice, and medical experience.
The term “migration” refers to the involuntary movement of hyaluronic acid outside the targeted area. This can result in uneven swelling, asymmetry, or progressive facial deformation.
It is important to distinguish controlled diffusion of the product into adjacent tissues (desired and planned) from true uncontrolled migration, which is not intended during the injection.
In the case of the chin, the risk of migration is extremely low when the procedure is properly performed, using an appropriate hyaluronic acid, injected at the correct depth by an experienced physician.
The chin is an anatomically favorable area for product stability for several reasons :
These anatomical characteristics make it an area very unlikely to experience migration, provided the procedure is performed according to best practices.
Certain factors can promote product migration :
When performed in a medical office by an experienced practitioner, hyaluronic acid injection in the chin is a safe and controlled procedure, providing natural, precise, and long-lasting results. Several factors explain this stability over time :
If an irregularity, swelling, or displacement appears in the weeks following the procedure, the first step should be to consult the injecting physician. In most cases, it is not true migration, but rather :
In very rare cases, exceptional in the practice of an experienced physician, if true migration is observed, a correction can be considered :
The post-injection phase is crucial to ensure the proper integration of hyaluronic acid.
Even though the risk of product migration is very low in this area, following some simple precautions can reduce it almost to zero.
During the first 48 hours, it is recommended to avoid any excessive pressure on the injected area :
Similarly, it is preferable to refrain from :
These post-treatment instructions, simple yet essential, ensure proper integration of the gel, guaranteeing even distribution and a stable, natural result over time.
It is extremely rare to observe late migration, several months after a properly performed chin injection. When irregularities appear long after the procedure, they are most often due to incomplete product resorption, giving the illusion of misplaced volume, localized swelling from a delayed tissue reaction, or an initially superficial injection that gradually alters the contours over time.
It is important to emphasize that true migration, meaning an unwanted displacement of the product from one anatomical plane to another, is exceedingly rare in this area.
Any anomaly observed several months after the injection warrants a follow-up consultation. In most cases, the physician can confirm that it is a transient phenomenon or natural resorption, requiring no intervention.
The type of hyaluronic acid injected plays a crucial role in the quality and stability of the result after a session. Not all hyaluronic acids are equivalent: they differ in their degree of cross-linking, which corresponds to the number of bonds between molecules; their cohesion, meaning their ability to stay grouped; their viscosity, which defines the gel’s fluidity or firmness; and finally their elasticity, reflecting their resistance to mechanical pressure.
For chin treatment, it is essential to use a highly cross-linked, dense, and cohesive hyaluronic acid. These specific gels are designed to provide structural support, maintain stable projection, and durably reshape the mandibular line.
Conversely, a hyaluronic acid that is too fluid or poorly cohesive, suitable for mobile areas such as the lips, under-eye hollows, or fine lines, should never be used to correct the chin. It would risk being unstable, migrating, or deforming under mechanical stress.
The choice of product is therefore a critical medical step. It depends not only on the area to be treated and the type of aesthetic correction desired, but also on the expected duration of results and, above all, the injector’s expertise. In Geneva, chin hyaluronic acid injections are always based on this rigorous selection to ensure a natural, safe, and harmonious result.
Very rare, certain signs may indicate imperfect integration of the product, or even a minor complication. It is important to recognize them in order to contact the injecting physician and schedule a follow-up consultation.
The signs that should prompt you to consult your injecting physician are :
In the majority of cases, these manifestations do not indicate migration, but are due to a poorly distributed product, delayed integration of the gel, or a transient inflammatory reaction.
The treatment then relies on gentle massage performed by the physician, a possible touch-up, and in some cases, localized dissolution via hyaluronidase injection.
The key remains personalized follow-up. A well-monitored patient benefits from an optimized long-term result, with adjustments made as needed.
