Why aren't these face gem things more common?

I believe these shiny things look really good on a woman's face but for some reason it's not common at all where I'm at, is there somewhere these might be more common? Women gotta wear this more, is there a reason why they don't wear it more often? Is it cause it takes long to apply or whatnot?
