A new fad has swept through social media applications thanks to an Instagram filter that mimics the results of cosmetic surgery.

Videos of people using the filter on themselves—and their pets—have been shared on Twitter and TikTok in recent days, while the face-changing effect was first seen on Instagram by J. Augusto (@jhonyaugust), a filter content developer.

The “Pillow Face” filter imitates the effects of plastic surgery or botox, with ultra-smooth skin, expanded cheeks, and puffed-up lips.

It went viral over the weekend after singers Charli XCX and Hayley Williams, as well as Game of Thrones actor Sophie Turner, posted it on Instagram. Users shared the outcomes of a challenge with their family members.

Users are posting before and after photos of the filter on Instagram, and the hashtag #pillowface has been used in over 16,846 posts as of this writing. #pillowface has received over 966,000 views on TikTok, where people re-upload the results.

The craze has moved to Twitter, with at least one person displaying the filter on a pet cat and others joking or commenting on the photographs created with it.
