Hi and thanks for your question. How fast the fillers wear off depends on which fillers you use. For the longest duration in a temporary filler, I usually use Voluma and it gives my patients 1.5 to 2 years. Voluma is also reversible at any time with a simple enzyme injection. Once the filler wears off and the nose goes back to its original shape, I give my patients the option of repeating Voluma treatment or going with a permanent filler like Bellafill. This is also a very safe and effective filler, but it does not get dissolved by the body, so it lasts for many years. Whether temporary or permanent, Non Surgical Rhinoplasty takes 5 to 15 minutes to perform, involves minimal pain, minimal risk, no downtime or swelling and you can see the results immediately after the procedure. The other advantage to this procedure is that you do not get the long term problems of rhinoplasty. I see countless patients in my practice who develop cartilage collapse and unsightly skin changes over many years of post rhinoplasty scar formation. My philosophy is to always do non surgical procedures over surgery if you are a good candidate for both. If you do choose to have Non Surgical Rhinoplasty, make sure to find a physician who is very experienced in specifically this procedure and ask to see their before and after pictures. Hope that helps.
