I mean ageing technology (what the person might look like after 5 years etc) was also created for human trafficking victims, and I haven’t seen it really being talked about in many years now since it came out. Seems weird to base something on whether or not you’ve heard of it.
If the family doesn’t have a recent picture of the person without makeup, then yeah, this would be useful, since people can look pretty different without makeup. I’m the only one who has recent pictures of my wife without makeup for example, her friends and parents only have pictures of her with makeup since she normally does some when meeting them. She’s also half Chinese, so depending on how she decides to do her make up, can look way more asian or barely asian at all. If I didn’t have those pictures and something happened, the make-up pictures wouldn’t be as useful in searching for her.
