Does dissolving filler cause an allergic reaction?

Dissolving filler means injecting something else, and that raises a fair worry about an allergic response. The earliest thing to know is what the dissolving product itself can do.

The product that dissolves filler

The National Library of Medicine says plainly: "Hyaluronidase, particularly when used in high doses, can cause allergic responses." So the allergic reaction in your question has a named source, and dose is part of the sentence.

Whether testing comes first

Haute Living reports that "Skin testing for allergy before elective dissolution is occasionally performed but is not universal practice." A provider may or may not test, so ask before your visit which approach they take.

Filler complications in print

Two papers cover filler complications in general: The Demographics of Patients With Dermal Filler Complications and Complications of Dermal Injectables, a Retrospective Study.

Telling your provider about past reactions

Tell your provider about any past allergic response before dissolving begins. Readers in St. Johns, Florida, who notice a new reaction after a visit can tell their provider.
