What causes this

Vs this

I thought you need a wide jaw and protruding cheekbones, to have hollow cheeks, but this tiktok fag doesn't have cheekbones nor, is his jaw very wide, so how does he have hollows? Even, if it's slight hollows?

There's plenty of people who are at 12% bf with not even slight hollows. I think how much your cheeks will hollow out at a low bf percentage is just genetic.(Water)

Also, apparently, johnny depp was in the 15-18% bf in that picture apparently. Someone mentioned it here. Don't know if it's true tho.
