So, the treatment of a lump after injection of a hyaluronic acid is pretty straightforward. You can use hyaluronidase, an enzyme that breaks down hyaluronic acid, to remove the bulge.
As far as a permanent treatment of the fold, I would not recommend it. There is an adage - Permanent fillers cause permanent problems. Use a filler that will provide a great result, but also has a great safety profile. The thicker hyaluronic acids such as Juvederm Ultra Plus and Perlane work well here.
Permanent products may not be the best, although fat is reasonable. I like to use hyaluronic acid fillers conservatively to soften them. Everyone has nasolabial folds, and they should. Perhaps they shouldn't be too deep and that is the goal.
I really wouldn't suggest something "permanent". Here's the issue: when we put something permanent in, like a cheek implant, when you are as young as you are, your face is going to continue to age around it. I promise that when you are in your mid-30's that cheek implant is going to look bizarre and weirdly placed. So I would just suggest some fillers be done. Your lines are not excessive or deep!

A permanent fix is tough to say. I think you probably would need something to fill in your cheek above the folds to pull the folds up. Usually filler is done for this purpose, but that would not be permanent. Cheek implants would be a consideration. Good luck!
