Lip Filler for Keloid Prone Patient?

Dear MOMSUE, Keloiods with injectable fillers is uncommon. In Medicine nothing is 100%. it would be best for you to start with something like a Hyaluronic Acid such as Restylane if you were to have an injection. Make sure you carefully monitor things and see your MD if anything suspicious is happening.

Although keloids of the lips (that is the vermilion or red of the lips) are rare, that complication would be one potential risk in your case, given your tendency to keloid. I have injected many patients who generally tend to keloid, with needles in their normal skin for other medical reasons and have never seen keloids as a result of injecting their normal skin. I think the risk is very low, but not zero.
Good luck.

I really have not heard of anyone who had keloids form as a result of a needle stick for the insertion of filler material.  So I doubt that you have to worry about this possibility.
