The most common risks associated with cheek filler include pain, swelling, bruising and redness at the injection site. These side effects are usually temporary and will go away within a few days to weeks. In rare cases, there may be an allergic reaction to the substance injected or infection at the injection site. Patients may also experience lumps or bumps at the injection site if the product is injected too deeply or unevenly into tissues. It is also possible for fillers to migrate outside of their intended area, causing asymmetry in the face.
To reduce these risks, it is important to go to a qualified practitioner who has experience with cheek filler procedures, as they will know how to inject the product correctly and safely in order to achieve optimal results without any complications.
