You know how everything has a jar symbol on it now and a lipstick is meant to be binned after 12 months etc? Do you stick to that? I buy travel sized mascara and bin it every 6 months but that's about it. I've got a lipstick that's 3 years old is it realistic to think it's ok? Or is there going to be mould and stuff on it? They never used to have the jar symbols on.
