One way to look younger is right under your nose, a UCLA-led study shows

From face lifts to facials and fillers, there are many ways you can reduce the inevitable signs of aging. But there is one cosmetic procedure that most people don’t consider a means that can make women look years younger.

According to a new study led by UCLA researchers that uses a type of artificial intelligence known as machine learning, a nose job, or cosmetic nose surgery, can make a woman look up to three years younger.

Researchers used the technology to examine before-and-after photos of 100 female patients, ages 16 to 72, all of whom had a Dr. Jason Roostaeian, a plastic surgeon at UCLA and senior author of the article. Twelve weeks or more later, standardized photos were analyzed using the technology that estimates a person’s age by clipping the face from a photo and then extracting a prediction through an algorithm.

“Rhinoplasty is widely recognized as a facial beautification technique, but not widely known for its anti-aging benefits,” said Dr. Robert Dorfman, lead study author and resident physician in the plastic and reconstructive surgery department at the David Geffen School of Medicine at UCLA. The study was published in the Aesthetic Surgery Journal.

Rhinoplasty involves making structural changes to bone and cartilage through small incisions in the nose and, if necessary, around the nostril while the patient is under general anesthesia. The rhinoplasty procedures in this study were tailored for each patient to best fit the person’s face.

Until now, Dorfman said, there has been little to no objective scientific evidence of the rejuvenating effects of rhinoplasty. “This technology enables us to accurately assess age in an objective manner and has been shown to detect patterns and features of aging that are beyond what the human eye can see,” he said.

The results were even more dramatic in women over 40, some of whom looked an estimated seven years younger after having a nose job. However, because the sample size of the group over 40 was small (25 women), the researchers said more studies would need to be done to validate the results. (The average age of the study participants was 32 years.)

The nose is usually not the focus of an antiaging treatment. But like other body features, the human nose, which is made up of soft tissues, cartilage and bones, ages.

“The nose loses its grip with age and can take on a more prominent or drooping appearance,” said Roostaeian, associate clinical professor in the Plastic and Reconstructive Surgery Department at the Geffen School.

The nose is also affected as other facial features age. “When we lose facial fat and volume in our cheeks, which are the canvas that our nose sits on, the nose becomes more prominent.”

By refining the nose, the youthful appearance of the entire face can be refined. “We thought that subjectively for many decades, but now we have objective evidence through artificial intelligence to support this.”
