Chronic edema around eye after HA fillers?

These products have a life cycle.  Eventually the old product that persists for years needs to be cleared out.  Enzyme treatment will remove the old filler product.  About a week later, you can be retreated without the chronic bogginess.  You don't need antihistamines, prednisone, or unnecessary laser treatment.

While there are several possibilities, biofilm formation (like a chronic infection) could definitely be going on in a scenario where chronic swelling is occurring in the location of filler injections and previous infection. An in-person exam is definitely warranted, but the fillers may need to be dissolved with hyaluronidase, and oral antibiotics may also be needed. A visit with a board-certified physician injector specializing in facial aesthetics is always recommended.

Need photos or examination to tell you. It could be edema, residual filler, your own eye fat, or combination. Treatment depends on the cause. See an oculoplastic specialist.
