Non surgical procedures such as fillers like Radiesse are very helpful to improve the shape and contour of your nose, but can be temporary, and are only suitable for certain cases. Surgical rhinoplasty is often the best solution for a more permant solution. Without a photograph, it is difficult for me to give you a recommendation for the best procedure for you, but if you are looking for a slimmer nose you will probably need a functional rhinoplasty. A consultation is always necessary to give you definitive recommendations on how to improve the contour of your nose.
