Hematoma from lip injections? What do I do?

Dear magshal,Juvederm has significant swelling post injection. I would follow up with you plastic surgeon but typically I tell all my patients to wait a full two weeks.  Generally at 2 weeks they are happy and glad they didn't dissolve. You can try icing it and keep your head elevated. Daniel Barrett, MD, MHA, MS

Hematoma is rare after lip injections but can happen if a blood vessel is directly punctured and/or the patient is on blood thinners. Icing should help as will time. Probably wise to avoid aspirin or NSAID drugs like ibuprofen/naprosyn/alleve until the swelling and bruising resolve. Your physician could drain the hematoma with a small needle prick if it's superficial but it is likely to go away on its own in time. The risk of trying to drain a small hematoma is the potential to infect the filler (rare as well) or to end up having some of it extruded when the blood is evacuated. I suggest close followup with your doctor.

Dear magshal,
I would recommend after 48 hours of icing change to warm compressor, it should resolve over time. 

A hematoma is possible after lip injections and will eventually resolve. It is not dangerous. I would treat with oral arnica and a vascular laser to shorten the duration of the bruising. Using cannulas will decrease the risk of this as well as an experienced injector.

Bruising is fairly common after injectables, especially in areas that have a lot of blood vessels such as the lip.  We take especial care for this reason to take precautions that minimize bruising, and have had a great deal of success with limiting or even eliminating this.
However, once bruising does occur, a little pressure immediately after the injection can reduce the amount of spread.  If there has been some time that has passed, alternating warm and cold compresses can sometimes help speed up your body's process of absorbing the hematoma.  Ultimately it will go away on it's own.
