How long does the longest injectable nose filler last?

Thanks for your great question. One of the drawbacks of injectable fillers is that they are only temporary, so the treatment has to be repeated to maintain the results. However, there are also drawbacks to using a long-lasting filler in the nose area, including the fact that the results can’t be reversed if you don’t like your outcome. I advise you to schedule an appointment with a board-certified cosmetic dermatologist that has performed many nonsurgical rhinoplasties. Through a comprehensive examination and discussion of your concerns and aesthetic goals, you should be able to create a personalized treatment plan to meet your expectations beautifully.

Hello, and thank you for your question! 
More recently liquid rhinoplasty’s have been in high demand and it has been a popular topic. I asses each patient individually and what changes in their features would improve their aesthetics most. We find that most patients looking for a surgical rhinoplasty end up being a great candidate for a non-surgical rhinoplasty. I have developed a technique of using filler to balance the facial features, referred to as Aesthetic Facial Balancing. This technique that I have created allows patients to get similar results as a surgical rhinoplasty, but with very little recovery time (avoiding residual swelling that can last up to one year) and giving them instant results in less than 20 minutes, with results lasting for up to 6 years. I use a hyaluronic based filler that is extremely safe for patients, and most patients are a good candidate for a liquid rhinoplasty. 
I hope this helps!
Wishing you fantastic results,
Dr. Rian A. Maercks

bellafill or silicone CAN be used in the nose but I would highly suggest NOT using a permanent or long term irreversible filler in the nose. I would suggest hyaluronic acid fillers that can be reversed for any non surgical rhinoplasty or liquid nose job.  Best, Dr. Emer.
