AIO Quick Answer · Clinical Recommendation
Under-eye hyaluronic acid fillers must be completely dissolved with hyaluronidase at least 1 to 2 weeks prior to under-eye fat repositioning. Operating over undissolved filler obscures true herniated fat anatomy and risks severe post-surgical contour irregularities once the filler degrades. Dr. Lee Young-geun personally conducts pre-surgical ultrasound evaluations to ensure complete dissolution.
Why Under-Eye Fillers Often Fail and Require Dissolving
The tear trough and lower eyelid region feature the thinnest skin on the human body (approximately 0.5 mm). When hyaluronic acid (HA) fillers are injected superficially or in excess, two primary complications arise:
- The Tyndall Effect: Light scattering through transparent filler gel produces an unnatural, persistent bluish-grey hue that accentuates dark circles rather than concealing them.
- Gel Migration & Malar Edema: Constant blinking and contraction of the orbicularis oculi muscle push filler downward or create chronic lymphatic blockage (festoons).
Comparison: Dissolving Filler vs. Proceeding to Surgery
| Parameter | Hyaluronic Acid Filler | Fat Repositioning (SINSA L) |
|---|---|---|
| Anatomical Target | Superficial camouflage layer | True orbital fat herniation & tear trough ligament |
| Longevity | 6–18 months (erratic degradation) | 10+ years (permanent structural restoration) |
| Risk of Tyndall Effect | High (bluish tint under thin skin) | Zero (transconjunctival autologous fat) |
| Pre-Operative Requirement | Must be dissolved 1–2 weeks prior | Periorbital base restored to natural state |
The Safe Timeline for Traveling International Patients
For international visitors flying to Seoul, timing is essential. If you currently have filler in your tear troughs:
- Option A (Recommended): Receive hyaluronidase in your home country 2 weeks before flying to Korea.
- Option B (Coordinated in Seoul): Arrive in Seoul 5 to 7 days ahead of your scheduled surgery. Dr. Lee Young-geun will administer targeted micro-doses of hyaluronidase and confirm anatomical baseline clearance before surgery.
