Just a few years ago, if you wanted a new nose—smaller, straighter, smoother—you could either a.) have a rhinoplasty or b.) that’s it. You had no other options. But with the rise of injectable fillers came an off-label use for them capable of transforming your entire profile in under 15 minutes: the non-surgical nose job.

Working with the same hyaluronic acid gels used for lips and cheeks, a doctor can correct curves, bumps, and lumps, making your nose appear smaller (even though it’s technically getting bigger).

The facial cosmetic surgeon often credited with inventing the technique is Dr. Alexander Rivkin, though hundreds of plastic surgeons and dermatologists now offer the service across the country. The before-and-after photos are so unbelievable that you might just think the “lunchtime nose job” is too good to be true—an Instagram fable, if you will. It’s not.

We caught up with Rivkin to help separate myth from fact, and to get all the information you need to know about the new nose job.

  1. Temporary Or Permanent—It’s Your Choice

Most cosmetic fillers are temporary. The injections last anywhere from three months to two years, depending on the type you choose, before slowly dissolving. People often scoff at the procedure’s fleetingness—why even do it if you’re going to have to go back over and over again? Rivkin will start a patient off with a temporary filler (“Voluma lasts for a year and half, and it’s reversible and natural looking,” he says) before moving on to a permanent filler. “Once the temporary one dissolves, I have them come back and use Bellafill, a permanent filler.” While you can correct your nose using Voluma in one 15-minute session, Bellafill (a collagen-based injectable used typically used to treat acne scars) takes three spaced-out sessions to see the final result that will last years.
