There are limitations of a non-surgical rhinoplasty procedure. It cannot reduce the nose nor address breathing problems where as a nose job would. However, where the issue is cosmetic, dermal fillers can be used to disguise humps and dips in the nose profile for a straighter looking nose.
As dermal fillers are used, the result is not permanent (unlike nose job surgery). However, the procedure can be repeated when the fillers wear off after 6-18 months.
