wtf it's for girls isn't it???! (To take a good " like face selfie?" To highlight their makeup and stuff?.. No? ...Why would a guy have / use one??! ) you don't take a physique picture with it correct? It's just for face close ups ....
For many, it's for proper lighting which is generally used for Zoom or Microsoft Teams calls. It's a 100% difference maker if your laptop is in a room without much natural light, and has gotten super popular for people who work out of their house as all their day to day work contact is over the internet.
I don't have one, but probably should, if I cared what I looked like. But if I was Client facing, etc, would definitely procure one.
