Without actually seeing your nose, it is unlikely that a poly beak could be corrected with nonsurgical fillers. If you have a large Pauly beach it would likely need to be fixed with surgery. If you put too much filler your nose would look unsightly it would probably look like your original knows. Poly beak deformity is caused when either there is not enough support in the tip or there was not enough of the septum taken down. Fortunately it is an easy correction that can be done.
A full set of facial photographs and an in-person examination required to make a determination of what is causing the polybeak deformity. Poly beak can because by residual cartilage left in the supratip portion of the nose, or thick-skin with fluid retention and scar tissue formation. A revision rhinoplasty is required to shave excess cartilage, while steroid shots and taping can help when there is fluid retention buildup in the supratip area of the nose causing the Polly beak.
