What filler is best for me to acheive pillowy plump lips?

Which filler is best for my thin upper lip? I did half a syringe of restylane a year ago and it made only a smalll difference and disappeared 3.5 months in. When I have lip filler it balances my nose, but I don't want to spend the money for just a tiny difference like last time. Will my upper lip shape respond well to a full syringe or is that crazy? I like the Hailey Baldwin "pillow" look the most with the little tiny gap in the center and those are definitely man made. (Pictured) Thanks!
