16 April 2012The number of people choosing to have cosmetic surgery procedures to improve the look of their chin is on the rise. Changing attitudes towards cosmetic surgery in countries across the world, and the fact that it is not possible to use diet or exercise to change the shape of a chin, is believed to be behind the increase.Jennifer Aniston's chin is one that is admired by many who want to achieve the same "strong-jawed" look, said a report by Today Health. As Dr Darrick Antell, a Manhattan-based plastic surgeon and clinical professor of surgery at Columbia University, puts it: "You're either born with it or you see a surgeon to improve it." And figures from the American Society of Plastic Surgeons suggest people are increasingly doing just that. Data from the organisation has revealed that almost 21,000 people in the US had a chin procedure last year - a 71 per cent increase on 2010. Dr Antell believes that social media and new technology may be one reason why people have become more image conscious. He said: "People have cameras everywhere. You can be at a wedding at the buffet table and a moment later see pictures of your double chin on Facebook. We're a much more image-driven society than we were even five years ago."
