You may not want to part with your favorite tube of mascara, but we hate to inform you that it has the earliest expiration date when it comes to makeup. Mascara lasts around three to six months, and shouldn’t be kept around for longer.
Think about it: You’re putting it right near your eyes. An old tube of mascara could be an eye infection waiting to happen, so consider swapping your old tube for a new one each season to stay on the safe side.
