What is wrong with my lips after lip filler? (Photo)

You have two options for addressing the issue. Firstly, you can have the filler dissolved on the right side using hyaluronidase. Alternatively, you can get more filler in the left side to make the lips symmetrical. It's important to note that regular massage will not rid of the excess filler.

This response was dictated. My apologies for any potential grammatical errors.
The problem area on your upper lip is most likely a slight embryological development defect similar to what happens in individuals were born with a cleft lip or cleft palette.
In your case it didn’t develop a cleft, but most likely had incomplete fusion during that time of embryology.
The problem is not Simply a lack of volume and attempting to correct this with filler is a simplistic approach, which should not be attempted and would only be done by someone who doesn’t understand the primary problem.
I do not recommend continuing, attempting to fix that defect using fillers.
It’s probably not enough to warrant surgery and I think you’re better off just leaving things alone.
Fillers placed correctly should not need to be massaged afterwards.
I cannot emphasize enough the importance of provider selection before having any Procedure.
