They are the trademark of celebrities such as Kim Kardashian and Justin Bieber.

Now, a rising tide of people are going under the knife desperate to enhance their image, driven by a desire to take a better selfie.

From rhinoplasty to eyelid lifts, plastic surgeons say they have seen a surge in patients keen to improve their image.

And the driving force? Selfies and the pressure people feel to improve their profile on social media sites.

A poll by the American Academy of Facial Plastic and Reconstructive Surgery found one in three surgeons have seen a rise in requests for procedures as a result of patients being more aware of their image on social media.

The 2,700 respondents noted a 10 per cent rise in nose jobs, rhinoplasty, in 2013 compared to 2012.

And in that time they said they have seen a seven per cent jump in hair transplants and a six per cent jump in eyelid surgery.

Dr Sam Rizk, a Manhattan-based plastic surgeon, said: 'There has been a 25 per cent increase over the past year-and-a-half to two years.

'That is very significant. They come in with their iPhones and show me pictures. Selfies are just getting to be so crazy.'

Dental hygienist Jennifer Reynolds has always been self-conscious about her looks.

She never indulged in selfies and felt uncomfortable being tagged in photographs posted on social media.

The 34-year-old from Costa Rica who lives in New York, opted for plastic surgery on her nose.

Since her operation she said she now feels ready for social media.

'I definitely feel more comfortable right now with my looks,' she said. 'If I need to take a selfie, without a doubt, I would have no problem.'

She is just one of a growing number of people who have turned to plastic surgeons to enhance their image.

But Dr Rizk, who specialises in rhinoplasty, said not everyone who requests surgery needs it because a selfie produces a distorted image that does not represent how a person really looks.

'We all will have something wrong with us on a selfie image,' he said.

'I refuse a significant proportion of patients with selfies because I believe it is not a real image of what they actually look like in person.'

Some patients get upset when Dr Rizk tells them surgery is not necessary, and he knows they will simply go to another surgeon.
