Higher Occurence of Cold Sores After Lip Injections?

Hello SLK.  The answer to your question is yes, we have seen this type of reaction previously.  More often than not, it is after the more traumatic procedures such as laser resurfacing, but any trauma around the lips can bring on a cold sore as well.  The onset of the cold sore may be quite some time after the actual procedure and during the healing process.

If this is a recurring issue in the months after treatment, ask your practitioner for a prescription to head off the problem before you come in for your treatment.  Good luck.

Cold sores can be triggered by any sort of stress, physical or emotional. The introduction of a needle into the lip, as during a filler injection, is one such stressor. The concern for cold sores is usually immediately after the treatment. For this reason, I recommend that anyone with a history of cold sores start an antiviral prophylactically prior to lip injections. 

Trauma and a compromised immune system can allow cold sores to recur. But filler injections should not increase the frequency of recurrences after the treatment session.
