Filters have never been more prevalent – and it’s leading some people to have fillers, Botox and other procedures. What’s behind the obsessive pursuit of a flawless look?

People used to call Anika the Snap Queen. Between the ages of 19 and 21, she was “obsessed with Snapchat, to the point where I had 4,000 followers”. At the peak of her “tragic” behaviour, she reckons now – a year after quitting the image-sharing app – she was taking 25 selfies a day.

She liked the sense of having a platform, she says, with the average selfie getting 300 replies. “It was like, ‘Oh my God, I’m so popular – I’ve gotta show my face.’” But the filters were also part of the appeal. The Londoner had long been insecure about the slight bump in her nose. Snapchat’s fun effects, which let you embellish your selfies with dog ears, flower crowns and the like, would also erase the bump entirely. “I’d think, ‘I’d like to look how I look with this filter that makes my nose look slimmer.’”
