Is the bump on my philtrum migrated lip filler? (photo)

It's possible that that bump is migrated filler. You also have migrated filler above the vermillion border causing the "shelf" appearance to your upper lip. This can easily be dissolved with hyaluronidase.

Dear User_Profile_Random,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Hi and welcome to our forum!From your lateral view photo, I note a significant bulge involving the upper lip. Assuming that you recently had lip filler, and the bulge developed shortly after injection, it is a likely probability. Aberrant hyaluronic acid based lip filler can be dissolved with hyaluronidase, an enzyme which breaks it down. Revisit your plastic surgeon for treatment.Best wishes...
