What do you recommend for projection after Voluma migrated after 4 months? (Photos)

I am wanting projection in my upper lip. Voluma worked great, but migrated after only 4 months. Recommendations? I had .5 ml Voluma in my top lip 4 mths ago and initially loved that it gave me nice projection. My philtrum is naturally a little too long for my face and my top lip had no projection, which made for an unflattering side profile. The projection is looking flat again after only 4 months, which this filler is supposed to last 12-18 months (I understand it likely migrated). I’m not sure if the rhinoplasty I had 2 months ago has affected this. I’m looking for recommendations, filler or surgical.
