You probably don’t want to hear this, but you can’t keep using your makeup forever. Makeup can expire.
But expiry dates don’t really give you a clear indication of when to ditch your products. Why? Because the minute you open your makeup, you’re exposing them to oxidation and bacteria.
Powders, like compact foundation, eyeshadow and blush, will start to change color and texture after 12 months. Concealer, liquid foundation and lipstick will start to dry up, and the oil and coloring components will separate after six months. Mascara gives off a strange, chemical smell when it goes bad.
But why wait till everything smells or looks funky? As a rule, change your powders, liquids and lipsticks every six months. And anything that goes near your eyes should be replaced every three months. The last thing you want is an eye infection like conjunctivitis.
