By then you probably are running out of product anyway, but if you’re not, you’ll start to notice the mascara is a bit clumpier and it doesn’t apply in the same smooth coat it once did. Those are signs it’s time to kiss that wand goodbye and invest in a new, fresh bottle of mascara. You’ll notice the difference when you put it on, we promise. And you’ll thank us when you don’t get an eye infection, which looks as bad as it feels.
