Is it safe to use steroid injections solely for slimming the nose (non-surgical rhinoplasty)?

I recommend getting a formal evaluation with a cosmetic dermatologist to go over your desired results. Facial fillers (like Voluma, Restylane, Juvederm) can be used to improve the symmetry of the nose, but surgery would be needed to improve nostrils or overall shape. Best to see an expert. - Dr. Emer

A steroid, such as Kenalog, can be helpful post rhinoplasty to decrease swelling and reduce scar tissue formation, however, steroid injections without surgery are likely to do nothing. If something sounds too good to be true, it likely is. The best procedure to slim the nose is a surgical rhinoplasty. I highly recommend seeking a board certified plastic surgeon or facial plastic surgeon for an in-person consultation. It is important to do your research and look at each provider's before and after pictures.
