Blisters inside of my lip after Juvederm injections. Any suggestions? (photos)

Blistering on the lips after filler is not a common complication.  Blisters are most likely due to herpetic infection and can be present on the interior, aphthous ulcer, or the exterior of the lip.  In patients with a history of herpes labialis infection, it is a good idea to have oral therapy if needed after any procedure performed around the mouth.  Treatment of these types of lesions can involved topical or oral anti-virals.  For soothing pain, applying a calcium based anti-acid tablet directly to the area can improve the pain acutely.  Blistering could also theoretically occur from excessive swelling of the lip but this would generally not be localized.

I suggest going back to your physician to get a formal evaluation to determine if this is a cold sore or apthous ulcer versus filler migration/swelling or other.  Best, Dr. Emer.

It is possible that the injections have triggered a cold sore. I would return to your treating physician for examination to confirm the diagnosis and best treatment.  Best, Dr. Green

The lesion looks like an aphthous ulcer. They can happen after trauma and they are usually very tender. try to keep it clean and consult with your Juvederm injector."This

Thanks for your question. Your blister looks like an aphtous ulcer, which commonly occur after trauma.  If it doesn't get better in a couple of days, go see a dermatologist.  Best of luck to you, your lips look fabulous!
