What should you know about hyaluronidase gone wrong?

Temporary tenderness, bruising, and local swelling can follow an injection, but the pattern and direction of change matter. Persistent or increasing pain may signal tissue irritation or a separate filler complication. Redness with heat or discharge can suggest infection. Itching, hives, facial swelling, or breathing symptoms can reflect an allergic reaction. Unevenness may mean that filler remains, swelling is obscuring the contour, or the enzyme reached a broader area than intended.

Contact the injector and request an in-person review, giving the injection time, product information, symptoms, and any photographs that show progression. Do not massage forcefully, add filler, repeat hyaluronidase, or apply medicines recommended by an unqualified source. Keep the area clean and follow only the aftercare instructions supplied by the treating clinician. If the original injector is unavailable, seek another qualified medical service.

Seek urgent care for severe pain, mottled or pale skin, a dusky patch, blisters, rapidly spreading swelling, fever, or pus. Call emergency services for trouble breathing, throat or tongue swelling, faintness, or widespread hives. Sudden visual change, weakness, or confusion after facial injections is an emergency.

Ask what the examination suggests, whether any filler remains, whether infection or allergy is being considered, and which changes should be photographed or monitored. Confirm the exact product used and the point at which further treatment would be unsafe or unnecessary.
