Lip Filler Migration: Causes, Fixes & How to Prevent It
Lip filler migration happens when product travels outside your natural lip border. Left alone, it can blur your lip line or create a “duck-lip” shadow. The good news? Migration is manageable and, with the right injector, largely preventable.
Early signs your filler is migrating
A faint mustache-like ridge above the Cupid’s bow
Puffy corners or a swollen “shelf” under the bottom lip
Lipstick that bleeds even with liner
Lumps or ripples you can feel (and sometimes see)
If you notice any of these changes, book a review within two weeks. Acting early keeps the fix simple.
Why migration happens (technique vs. product)
Technique mistakes
Too-much filler, injected too fast, or into the wrong tissue plane can force product to spread. Poor after-care, heavy massage or strenuous exercise on day one, also nudges filler outward.
Product factors
Certain fillers are designed for soft spread. Fine for vertical lip lines, risky for border-building. Your provider should match gel thickness to the job. Training and product knowledge matter more than brand hype.
Dissolving migrated filler with hyaluronidase
Hyaluronidase is an enzyme that melts hyaluronic acid fillers in minutes. A small test dose rules out rare allergies. Complete breakdown takes 24-48 hours; bruising is mild and makeup-friendly. According to the Cleveland Clinic, the area is ready for fresh filler after two weeks.
Best practices to avoid migration
Choose an advanced injector. Look for medical credentials and portfolio photos shot at 4–6 weeks post-treatment.
Start low, build slow. Layering small amounts lets tissue settle naturally.
Mind the depth. Injecting at or just below the vermillion border anchors filler where it belongs.
Follow after-care. No facials, steam rooms, or vigorous workouts for 48 hours.
Schedule upkeep. Annual top-ups prevent over-stacking old product.
Can migrated filler be refilled safely?
Yes. Once the old product is fully dissolved and tissue calms, fresh filler can be placed with a refined plan, often using a firmer gel and micro-droplet technique. Expect two visits spaced two weeks apart for the best shape and definition.
