Pictures would help me evaluate your nasolabial angle and length of the upper lip. I don't believe that a plumping graft would solve a long upper lip. If your upper lip is too long, you would most likely need an upper lip lift. Most of the scar in within your nostril and hardly visible.
Another way to get elevation of the nasal tip is to remove the cephalic portion of lower lateral cartilage. This technique would give you tip definition and elevation, without making the nose shorter.

Pumping graft to shorten upper lip
Pumping graft may make a long nose look shorter but not the lips. On my experience, none of my patients had complained about the scar from lip lift. As long us you give it time and proper care, the scar on the area is usually inconspicuous.

I need to see photographs to give you an accurate answer of whether this would work for you. The technique of taking these photographs is described on my website. Lip lift scars should be quite fine and not noticeable.
Discuss a lip lift with your Plastic Surgeon. This can be done at the same time as a Rhinoplasty with excellent results. Ask him to show you some before and after photos. An incision is made at the base of the nose ( following the natural curves), and very little tissue is excised. Consult with a Board Certified Plastic Surgeon who is very experienced in these 2 procedures. Best wishes!
