Am I a good candidate for a Bullhorn Lip Lift? (photos)

I have always hated my top lip. I have dabbled with lip flips and dermal fillers but it is expensive in the long run and I haven’t quite gotten the results I’m looking for. My last injection experience wasn’t great. I don’t really want volume, just a larger top lip. Am I a good candidate? Do you recommend a time frame in which to wait before having this procedure if you have lip filler? I currently am going on almost a year without filler. Thank you! Your time and input is greatly appreciated.
