The FaceApp filter has taken over the internet. From celebrities to commoners, everyone is using this application. While Varun looks hot in his oldie look, we can’t take our eyes over Arjun’s picture. FaceApp was launched back in 2017 and it appears to have gone viral again. The photos are being shared online with the hashtag #FaceAppChallenge or #agechallenge. Many fan clubs are also sharing pics of celebs using the filter.
