A study conducted by the researchers of UCLA says rhinoplasty or cosmetic nose surgery is a way to make women look younger up to three years. They used a specific type of artificial intelligence called machine learning to come to this conclusion. This was recently published in the journal - Aesthetic Surgery Journal. The researchers conducted the study by using the technology to study the before and after photos of a total of 100 females aged between 16 to 72. All of the women associated with the study had undergone rhinoplasty for cosmetic reasons by a UCLA surgeon and others.
