Filler dissolution sounds straightforward — inject hyaluronidase and the filler dissolves. But in practice, it's far more nuanced than most patients realize, and the difference between a good outcome and a problematic one often comes down to two factors: ultrasound guidance and physician expertise.
The Problem with Blind Dissolution
Most filler dissolution is performed "blind" — the injector estimates where the filler is based on visual assessment and palpation, then injects hyaluronidase in the general area. This approach has significant limitations.
Filler can migrate over time, settling in tissue planes far from where it was originally placed. Without imaging, the injector is essentially guessing where the product has ended up. This can lead to incomplete dissolution, unnecessary tissue damage, or multiple sessions to address what should be a straightforward correction.
Why Ultrasound Changes Everything
Ultrasound allows the physician to see exactly where filler has settled — even product placed years ago that has migrated. Dr. Bui's background in diagnostic radiology gives her the ability to identify filler deposits with precision, distinguish them from surrounding tissue, and guide dissolution enzyme directly to the target.
This means more complete dissolution in fewer sessions, reduced risk of collateral tissue effects, and the ability to selectively dissolve specific deposits while preserving intentional filler placement nearby.
The Physician Factor
Filler dissolution isn't just a technical procedure — it requires judgment. Understanding tissue planes, vascular anatomy, and the behavior of different filler products over time is essential for safe, effective dissolution. At PH Med, Dr. Bui performs every dissolution procedure personally.
