Mascara should generally be replaced every 3-6 months, depending on the frequency of use and how well it’s been taken care of. After that, the mascara can start to dry out and become clumpy, making it harder to apply it smoothly and increasing the risk of bacterial infection.

It’s also important to replace your mascara if you’ve had an eye infection or any other eye ailment, as using old or contaminated mascara can make the problem worse.

To help extend the life of your mascara, make sure to tightly close the tube after each use and avoid pumping the wind in and out, as this can introduce the air and dry out the product more quickly. Additionally, try to avoid sharing your mascara with others to minimise the risk of spreading bacteria.
