The reaction can vary significantly based on the type of filler used: for HA it almost never happens, with PMMA it is uncommon but possible. With non-FDA approved fillers like silicone or “proprietary fillers” some offices use, this reaction is almost expected. That is why it is so important to use only FDA-approved fillers.

FAQ
Nodules are firm bumps or lumps that develop after filler injections.
They can be the size of a small seed to the size of a gumball.
They can occur in the first days or many years later.
Noninflammatory nodules happen soon after and should normally resolve spontaneously in days to weeks. They are treatable with hyaluronidase in the case of HA fillers.
Inflammatory nodules may present days to years after treatment and come from immune activation, infections, or bacteria/biofilm formation.
They have been, also with other viral infections, vaccines, and dental procedures.
Granulomas are immune reactions in which the body walls off filler material it cannot digest. Granulomas are more common with PMMA fillers. They are expected with silicone.
Fillers can create surfaces for bacterial biofilms—colonies of bacteria that provide protection from antibiotics. Biofilms can lead to chronic low-grade infections and ultimately lead to nodules.
That depends on the nodule type, but treatment includes time, hyaluronidase, steroid injections, and occasionally oral medications.
No. Nodules are considered rare, particularly when FDA-approved fillers are used and the provider is properly trained.
The risks associated with nodules can be reduced by using a skilled and trained doctor, following pre- and post-procedure instructions, and avoiding immune triggers such as dental procedures or vaccinations around the time of treatment.
Proper technique can limit noninflammatory nodules, and an experienced doctor like Dr. Sullivan can diagnose and manage the few cases of inflammatory reactions that do occur.
Ensure you contact your provider as soon as possible.
