I had tear trough filler (Panda eyes) injected previously; the first time went smoothly, but after the second session, it suddenly became inflamed and swollen. It has been two years now, and a lump appears whenever I smile, which often turns into a visible line when pressed. It’s very bothersome. Doctor, what methods can be used to dissolve it?

Hello, I understand that the situation you described can be very distressing. "Panda eyes" fillers (tear trough fillers) are essentially collagen implants, not Hyaluronic Acid (HA); therefore, the hyaluronidase commonly used to dissolve HA is not the direct method for treating this type of material. Furthermore, given that you experienced sudden inflammation and swelling after your second treatment, and now, two years later, you still have a protrusion when smiling and a visible line when pressed, I would prioritize identifying the root cause—whether it is residual material, migration, fibrosis, encapsulation, or tissue changes resulting from previous inflammation—rather than blindly attempting "dissolution." For filler issues that have already formed nodules or encapsulation, enzyme treatment is inherently limited. The under-eye area is highly delicate. To determine the appropriate treatment, an in-person assessment is necessary. When necessary, we use **Ultrasound-guided** imaging to clearly visualize the depth, extent, and nature of the material before deciding on the safest subsequent approach. **FillerRevision** emphasizes that such under-eye issues require millimeter-level localization and assessment via ultrasound.
