Although many people think facelifts simply make you look like you've had "work done", a new survey suggests that cosmetic surgery makes you look younger.
The study, from the Archives of Facial Plastic Surgery Journal, quizzed medical students on 'before' and 'after' pictures of 60 plastic surgery patients.
The students were asked to estimate the patients' ages in the photos, which were randomly mixed up.
On average, the students guessed that the 'after' patients were 7.2 years younger than their guesses for the same patient in a 'before' photo.
The main catch in the survey was that all the cosmetic surgery was done by the same, highly skilled surgeon – in the hands of an inferior surgeon the results could well have been completely different.
