Has it ever happened that you're browsing through your dresser and you come across lipsticks you don't use, a kajal pencil from five years ago and some mascara that just smells foul? Well, like all good things, makeup expires too. And using expired makeup can cause infections, inflammation – basically, the works! Here's a checklist to keep track of what you need to throw out and when.

Water-based foundations last up to a year whereas oil-based foundations last up to 18 months. Use sponges or brushes to apply since fingers can contaminate the formula.

Eye pencils

These can last up to one to two years depending on the usage. If you are using a pencil, sharpen it regularly to keep bacteria away from the tip of the eyeliner.

mascara

Any mascara, even from the best brands should be discarded in about 9 months. If you see it going dry or smelling foul, stop using it immediately. Also, don’t pump your mascara—this helps stop the growth of bacteria.

Lip colours

Creme, matte based colours can last up to two years. Store them in the fridge to avoid losing texture and consistency. Lip glosses have a shelf life of six months, so use it as much you can and then buy another one.
