Lip filler hit a blood vessel. Did I get cold sores out of this lip filler? (photos)

Thank you for sharing your question and photograph and I am sorry to hear of your bruising and swelling episode. If these cold sores broke out they are likely due to the trauma and irritation that resulted from your lip augmentation.  Treated with antivirals like Acyclovir/Valtrex they should clear quickly.  I would recommend pre-treating yourself with the medication prior to any future treatments.  Hope this helps.

Any inflammation around the lips can trigger a cold sore, even if you have never had one before.  This includes lasers, microneedles, and fillers.  With the medication you should heal fine.  In the future, you should pre-treat for a couple of days to decrease the chance of this happening again.
