How long does a hematoma from lip fillers last?

Bruising can last 1-2 weeks and hematomas will gradually resolve over a few weeks. I would wait a full 2 weeks before judging the results, but this may be superficially placed filler. If it is after the two week wait, you can have the filler reversed with hyaluronidase.
I hope this helps!

Dear hogangirl1983,your hematoma will most likely last several weeks before it resolves. I would suggest you to consult your injector for further information and recommendations. Daniel Barrett, MD

Bruising usually lasts between 1-2 weeks, but a hematoma will can take several weeks to resolve. Compresses and VBeam treatments may give improvement. Best, Dr. Emer

Bruising or hematoma resolution is different in every individual. In some people it will go away and just a few days and in others it may take up to 2 weeks. Helping your hematoma dissolve may involve application of moist, warm compresses four to six times daily.

Bruising after lip injections is common and can persist up to two weeks.  Depending on the size of the clot, your body will slowly break it down over the coming couple of weeks.  Return to your injector if you have concerns.
