Scar tissue bump, inner upper lip - can I dissolve this with Kenalog? (photos)

Fat transfer from abdomen to upper lip was in 2005 I noticed scar tissue lumps within the year but left it alone. I want to finally take care of this now but don’t know how to best go about fixing my lips. Would kenalog work for this? As you can see, it looks like it migrated a bit and you can see the bumps. I would be interested in dissolving what I can and doing fillers later, such as Restalyne Kysse, but need my lips to be “back to normal” so I don’t keep masking the problem!
