If you're a regular on Facebook, Instagram or Twitter, you might be wondering why your newsfeed has been looking... well, a little wrinkly this week.  

The 'old face' selfie trend came about thanks to a photo editing app that allows users to get a glimpse into the future where wrinkles, grey hair, and a slightly enlarged nose have replaced arched eyebrows, smooth skin, and high cheekbones.

To help you better understand this strange phenomenon, we've gathered the details, the fine print, and a few of our fav celeb transformations. 

Face App
Picture: Face App

The app
FaceApp, an 'Artificially Intelligent Face Editor' that launched back in 2017, is used to edit and adjust your selfies in a myriad of ways so that you can try out blonde highlights, a Hollywood smile, a beard or different coloured eyes - without the hassle of hair dye and contacts.

We don't know who kicked off the trend, but the app has earned a spike in downloads this week thanks to the popularity of its 'old face' filter which gives users an idea of what they might look like in their golden years.

And while some people felt comforted by the results...

Others were left reaching for the anti-ageing cream...

The fine print
You know those pesky terms and conditions that you scroll through without reading? Well, it might be time to give them a glance.
