I am not made of money, and if I were, I would not refresh my ENTIRE make up collection (and nail varnish) on a yearly basis! It would be a colossal waste of money!
I have eye shadows that I have had for nearly 10 years, nail varnishes the same. I use mascara for months and only change when it gets goopy! Nail varnish I throw away when that gets too goopy and any face powder or concealer (I don't use foundation) I change when I have used it all up!
AIBU or is there any basis for not keeping old make up?
