what are these little indent lines on my cheeks?

what are these little indent lines on my face?

i don’t know where they came from they just suddenly popped up one day.

they’re not smile lines because when i smile they don’t crease or when i scrunch up my face they don’t get deeper. i’ve tried facial expressions that would “cause” them but none match up.

my only guess is maybe weight loss? i lost 60lbs and i used to have a rounder face so maybe it’s just the skin stretch? my mom says it’s because of my use of KN95 masks during lockdown but i don’t think it would have done that.

i’d just like to find out what it could be. i’m not gonna get botox and other bs because i’m only 22 lol
