Can radiofrequency have smoothing effect on fatty nose?

I would not recommend that since these modalities are not accurate.  Small imperfections can be very visible.  Best of luck.
An in-person exam with a board-certified plastic surgeon would be the best way to assess your needs and guarantee a reliable medical advice. Best of luck! Dr. Michael Omidi.  

Thank you for your question. I have many patients that complain of an overly large nose and desire a conservative reduction.  The cause of this is varied. Contributions from the nasal bones and cartilage, subcutaneous fat and muscle, and the skin itself are all possibilities. An in person exam with a rhinoplasty specialist can give you a better idea of the cause of your problem and offer possible options.  They can also help guide you toward making a good decision before you invest your time and money on something ineffective.  If your issue is subcutaneous fat, this is usually addressed conservatively during rhinoplasty in concert with appropriate structural modifications to better redrape the skin to meet your goals. I do not have any personal experience with radiofrequency on the nose, but feel it is unlikely to make any improvement in the overall nasal contours/shape.  I hope this helps. Take care.
