PHOENIX -- How long do you keep your makeup? Do you keep using it long after it's expired?
Let's face it; lots of the makeup we use is expensive, so we hate to throw it away. But the problem is, your makeup bag could be filled with cosmetics you shouldn't be using.
Kaley O'Kelley talked to celebrity makeup artist Zethina, to find out what to keep, and what to toss.
"If it starts to stink, it's got to go!" Zethina tells us with a laugh. Truth is, most cosmetics do have a certain shelf life.
For example, wet products like primers, foundations and concealers should only be used up to about two years. Lip glosses and lipsticks are also good for about two years.
How about eye makeup? "Your pencils, you can push those a little longer, maybe about three years," Zethina says. "Sharpening it is how you're going to keep it nice and clean and sanitary."
Powders, powder foundations and powdered eye shadows can also last about three years.
But if you keep a product too long, it can affect how it works, and how it looks. "Your body oils mix with it, and when you apply it, it looks dark and muddy," she says. "Wash your brushes, and toss your products when they get old.'
As for mascara, it has a much shorter shelf life. "No more than four months, max," Zethina tells us. "At three months it really should go."
