In 2017, a viral trend swept the internet, titled ‘wavy brows’, it saw beauty influencers and fans of the trend drawing their eyebrows on in a wavy pattern – often created with a little help from Facetune. Two years on, there’s a brand new Instagram trend to match.

Though its origins are unknown, it’s believed to have been started by a Russian plastic surgeon (as many of the strangest beauty trends do) called Emelian Braude. Coined ‘devil lips’, or ‘octopus lips’, the procedure is said to involve inserting filler in the outer lip to create a wave effect across both the lips.
