New vein or migrated filler? (Photo)

Hi Stephanie,
An in-person consult would be needed here to give you an exact answer, however I have seen this before with lip fillers. Sometimes the tissue above the lip is a little thin or weak and the filler can disperse into that space and give that appearance. It may be worth dissolving to see if it makes a difference or removes that lump. If you decide to refill your lip, I recommend using a filler that is softer and natural and build your volume up slowly over time.

If you had your filler treatment almost two years ago it would be unusual for filler to migrate at this time. If there is filler present you can consider dissolving it with hyaluronidase which will help if the remaining filler is causing the superficial vein to be more noticeable.

This may be a line from filler injected close to the dermis or in the dermis. Gentle massage on the lip daily should improve this line. If not you can try dissolving with hyaluronidase.
