There's some images attached to this post [0], if you've used snapchat or tiktok/douyin they have pretty decent filters baked in but I guess the magic is making the video quality low enough to 'smooth' out the effect.

Also found an article [1] that looks at how much people are willing to spend and how far people are willing to go to hide their real look, things like buying silicon upper body suit(?) to get better looking boobs/frame or voice changers
