What are the main risks of under-eye filler injections?

Under-eye filler is popular, and so are the worries that come with it. Two published sources name the risks plainly, which makes them a good checklist for a consultation.

The risk the FDA ranks highest

The U.S. Food and Drug Administration calls unintended injection into a blood vessel the most concerning risk of dermal fillers, because it can block the vessel and cut off blood supply to tissue. The agency adds that the chances are low, but the resulting complications can be serious and may be permanent.

The cause-and-effect chain is short. A filler placed in the wrong spot can block blood flow, and tissue that loses its blood supply can be harmed.

Mild problems versus serious ones

A paper from the National Library of Medicine (PMC) says most adverse events of HA fillers are mild and transient, while more serious adverse events can occur and may be long-lasting or permanent.

Questions to ask before treatment

  1. How often do you inject the under-eye area, and how do you lower the risk of a blood vessel injection?
  2. What do you do if you suspect a blood vessel problem?
  3. What should I watch for afterward, and who do I call?
  4. Which filler will you use, and why?

Read the filler guidance yourself

The American Society of Plastic Surgeons has an overview of dermal fillers, and the FDA explains soft tissue fillers. The U.S. Food and Drug Administration also lists dermal filler do's and don'ts. For how one hyaluronic acid filler performs in routine use around the eyes, there is a real-world evidence report.

Bottom line

The risk is low but real, and the worst outcomes can be permanent. A provider who can talk through that openly deserves more of your attention than one who plays it down.
