What goes wrong with filler — and why it's more common than you think
The demand for filler correction has grown significantly alongside the growth of the filler industry itself. As more patients accumulate years of filler across multiple providers, the combination of volume buildup, suboptimal placement, and migration has created a large population of patients who don't love what they see — but don't know what to do about it.
At Plump Medical Spa in Newport Beach, ultrasound-guided filler assessment and dissolving is one of the four core specialties of the practice. Dr. Mortazavi regularly sees patients from across Orange County and Southern California who have had filler placed elsewhere and need it assessed, mapped, or dissolved.
The most important thing to understand: hyaluronic acid filler is fully reversible. Whatever the issue — migration, overfill, asymmetry, unnatural appearance, or complications — it can be addressed with hyaluronidase. The question is how precisely and safely it can be done.
The most common filler problems
01
Filler migration
Filler moves from the injection site into adjacent tissue over time. Most common above the lips (creating a "shelf" or duck-lip appearance), below the under-eyes (creating puffiness), and in the cheeks (spreading beyond the intended treatment zone). Migration is often painless and gradual — patients notice it months or years after treatment.
02
Overfill / filler fatigue
Multiple sessions of filler accumulation over years without adequate dissolving between cycles. The result is an over-volumized appearance — pillow face, heavy lower face, or disproportionate lip volume — where the face no longer looks refreshed but instead looks treated. A full filler reset with ultrasound-guided dissolving, followed by a fresh approach, restores proportion.
03
Poor placement or wrong product
Filler placed in an incorrect anatomical plane, at the wrong depth, or using a product with inappropriate viscosity for the treatment area. Examples include stiff filler placed superficially (causing visible lumps or Tyndall effect — a bluish tinge), or soft filler used in a structural area causing spread and shapelessness.
04
Asymmetry
Unequal filler distribution between sides of the face, creating visible asymmetry in the lips, cheeks, or jawline. Can be corrected by adding to the deficient side, dissolving from the overfilled side, or a combination. Ultrasound imaging identifies whether asymmetry is due to placement differences or anatomical variation before correction.
05
Nodules or granulomas
Hard lumps that develop at or near injection sites, either from filler that has become encapsulated or from a chronic inflammatory response. Most respond to hyaluronidase if HA filler is confirmed. Ultrasound imaging differentiates between filler deposits and granuloma formation before treatment.
06
Vascular complications
The most serious filler complication — accidental injection into or compression of a blood vessel, causing tissue ischemia. Requires emergency dissolution with high-dose hyaluronidase. This is rare but time-critical. Physicians with hyaluronidase on-hand and ultrasound imaging for vessel identification are best positioned to prevent and respond to this complication.
Why blind dissolving is not the same as ultrasound-guided dissolving
Hyaluronidase — the enzyme used to dissolve HA filler — is effective when placed accurately. The challenge is knowing exactly where the filler is. Without imaging, the provider injects enzyme where they think the filler is based on surface appearance and palpation. This is called blind injection, and it has three significant limitations.
Standard approach
Blind Hyaluronidase Injection
Injection placed based on surface appearance and palpation only
Cannot confirm filler depth, volume, or exact location before injection
Risk of dissolving in wrong area — missing migrated filler
Higher enzyme doses needed to compensate for uncertainty
Cannot distinguish filler from other tissue structures
Plump's approach
Ultrasound-Guided Dissolving
Butterfly iQ3 real-time imaging maps filler before any enzyme is placed
Confirms exact depth, location, and volume of filler deposits
Enzyme placed precisely into confirmed filler — not adjacent tissue
Lower enzyme doses needed — more targeted correction
Can identify vascular structures to avoid during injection
The Butterfly iQ3 at Plump
Plump Medical Spa uses the Butterfly iQ3 ultrasound device — a portable, high-resolution imaging system that displays filler as a distinct structure in real time. Before any dissolving is performed, Dr. Mortazavi images the treatment area to confirm the presence, location, and extent of filler. This transforms what was previously a procedure based on guesswork into one based on verified anatomy.
Your options at Plump
Step 1 — Assessment
Ultrasound Filler Mapping
A dedicated ultrasound imaging session to map all existing filler, assess placement accuracy, identify any migration, and determine which areas need dissolving. No dissolving is performed in this session — it is purely diagnostic. Recommended before any dissolving decision is made.
$299
Treatment — Full Dissolving
Ultrasound-Guided Dissolve
Real-time Butterfly iQ3 imaging during hyaluronidase placement. Filler confirmed before enzyme is injected. Includes post-dissolving assessment. Most sessions address a primary treatment area — additional areas available if needed at the same appointment.
$450
Filler placed at other practices is welcome. Plump Medical Spa regularly assesses and dissolves filler regardless of where it was originally placed. Bring any records of product type and injection dates if available — but imaging can assess filler presence independently. Most HA fillers are detectable on ultrasound.
Frequently asked questions
What is filler migration?
Filler migration occurs when hyaluronic acid filler moves from its original injection site into adjacent tissue over time. Most common sites are above the lips, below the under-eyes, and around the cheeks. Ultrasound imaging can confirm where migrated filler has traveled before dissolving is performed.
Can I dissolve filler that was placed elsewhere?
Yes. Plump Medical Spa regularly sees patients who need filler assessed and dissolved regardless of where it was originally placed. Ultrasound imaging identifies HA filler deposits independently of where they came from.
How quickly does filler dissolving work?
Hyaluronidase works rapidly — most filler shows visible reduction within 24–48 hours. Full resolution is typically assessed at 2 weeks. Some patients require a second session for complete clearance of dense or layered filler deposits.
Does dissolving hurt?
Topical numbing cream is applied before the procedure. Most patients describe mild stinging similar to the original filler injection. The enzyme solution itself may cause brief warmth or flushing in the treatment area.
How much does it cost to dissolve filler at Plump?
Ultrasound filler mapping (assessment only) is $299. Ultrasound-guided dissolving is $450 per session. Standard dissolving without ultrasound is $350. Cherry Financing and CareCredit are accepted.
