Why do certain makeup products just smell so bad?

I don’t want everything to have fragrance or anything, but why can’t something be truly unscented instead of smelling off?

My huda beauty concealer smells like the natural kind of Play dough you make at home, it’s so weird. And I just bought a Kosas setting powder today and it also smells off, a little bit of that play dough smell and Pennies.

How come I’m paying for this shit for it to smell like that? It’s not even the normal makeup smell. These products aren’t cheap either, it’s big brands 🫩
