What exactly is lip filler migration?

Hello, thank you for reaching out.

Lip filler migration occurs when dermal filler (usually hyaluronic acid-based) moves beyond the intended treatment area, often resulting in a puffy or uneven appearance around the lips. Here are the main reasons why filler migration can happen:

1. Overfilling
Injecting too much filler can exceed the tissue’s capacity, causing the product to spread beyond the lip border.
2. Poor Injection Technique
Incorrect depth, angle, or placement of the needle or cannula can lead to uneven distribution or migration of the filler.
3. Wrong Type of Filler
Softer or lower-viscosity fillers may migrate more easily than those designed for structure and projection, especially if not matched appropriately to the area. Filler will always follow the past of least resistance. A filler with an appropriate g-prime (amount of hyaluronic acid filler) or appropriate amount of filler must be used to not overwhelm the lip structure.
4. Frequent Touch-Ups
Repeated injections before the previous filler has fully settled or metabolized can lead to buildup and movement over time.
5. Muscle Movement
The lips are highly mobile due to frequent talking, eating, and expression, which can encourage migration, especially shortly after the procedure.
6. Pressure or Trauma Post-Procedure
Rubbing, massaging, or applying makeup too soon after treatment can cause filler to shift.
7. Inexperienced Injector
Practitioners without sufficient training or experience may use improper technique or judgment, increasing the risk of complications like migration.

Hello, I’m Lauren, the aesthetic injector at Colorado Plastic Surgery Center. Lip filler migration refers to the movement of the filler from the lip area to adjacent areas, typically above the lip. This can create an unnatural appearance. This can be caused by too much filler, improper technique, etc.

“Lip filler migration” refers to filler moving beyond the intended injection area, Let’s break it down:In some cases, the filler literally moves (or seeps) upwards into the tissue above the lip line, causing a fuller or slightly swollen appearance just above the vermilion border. This can happen if too much filler is injected, or if the filler is placed in a plane where it can easily shift over time.Alternatively, the filler may remain in the lip but is either injected too high or used in excessive volume. The result is that it pushes or bulges the tissue near the border, creating the illusion of migration even if the product hasn’t truly traveled outside the lip. A skilled injector will minimize these risks by using appropriate volumes and careful technique. If you suspect migration, a consultation with a qualified provider can help determine whether you need minor adjustments or dissolving for a more natural result.
