I actually find it very concerning indeed & it's happening to younger & younger children as well.
The modern phones & apps have filters that will whiten your eyes & teeth, clean up your skin, give you a glowing tan & put a shine to your hair.
This narcissistic behaviour is being compounded because whole generations are doing it so it is normalised behaviour but it's not healthy.
They are becoming more & more insecure with judgements made on people's character according to how they look.
It's doing long term damage to young minds who are only learning to emote.
