Within the past several days, folks have been peeking into the future thanks to a mobile photo-editing app called FaceApp, which was created by a Russian startup.

The app features an aging filter that uses artificial intelligence to add a few extra pounds, some wrinkles and a bunch of gray hairs to your pictures.

Many, including celebrities, have participated, uploading photos of their old selves to Twitter and Instagram.

Lil Nas X, Ludacris, the Jonas Brothers, Ari Lennox, Lena Waithe and many more have taken on the challenge.

A few were surprised by how realistic the images looked.

And others joked that the trend was taking over their social media feeds. The hashtag #FaceAppChallenge was a trending topic on Twitter Wednesday.

While users have expressed concern about the privacy policy, which says FaceApp “cannot guarantee that information on the service may not be accessed, disclosed, altered or destroyed,” the company recently addressed the fears.

"We'd like to comment on one of the most common concerns: all pictures from the gallery are uploaded to our servers after a user grants access to the photos," the brand said in a statement to TechCrunch. "We don't do that. We upload only a photo selected for editing. You can quickly check this with any of network sniffing tools available on the internet."
