Yes, it may be treatable, but the first step is figuring out what the bulge actually is. After Radiesse, a fullness near the outer upper lip can be caused by: Product placed too superficially or migrating A small nodule or lump Inflammation / tissue reaction Less commonly, a change in how the surrounding tissue is sitting Important Point About Radiesse Unlike hyaluronic acid filler, Radiesse cannot simply be dissolved with hyaluronidase, so treatment depends on the cause. Possible Treatment Options Depending on exam findings, treatment may include: Massage, if it is very early and soft Steroid and/or 5-FU injections for a persistent lump or inflammatory nodule Needle release or small excision in selected cases if the area is localized and does not improve Sometimes just time, if it is still evolving Because this is close to the lip, I would be cautious about any aggressive treatment without a proper in-person evaluation. I’d recommend seeing a qualified, board-certified plastic surgeon, facial plastic surgeon, or experienced injector who regularly treats filler complications, especially Radiesse nodules or contour irregularities. Good luck!
