Non surgical nose job, how effective is this?

Not likely effective: I am not aware of any non surgical methods of nasal correction that are effective. Cosmetic rhinoplasty involves shaving and cracking bones, shaving and repositioning of cartilage. This is not achieveable without surgery.

Temporary: It can temporarily improve minor depressions or asymmetries.

Liquid rhinoplasty: Nonsurgical rhinoplasty entails injections with fillers and is considered an off label use of the product. For your best options, have your nose evaluated by a board certified facial plastic surgeon.

Great for short term: This will not make a nose smaller but is a great option for short term correction of relatively mild irregularities
