I hate when my mascara dries out. And it happens soon after I buy so it isn’t about it being old. It just dries out due to environmental conditions. You’re only supposed to keep mascara for three months because beyond that point, it can collect bacteria and lead to eye infections. But, if your mascara dries up within those three months, make sure you eye drops to refresh it.
