How long should I keep makeup?

CLEAN OUT YOUR MAKEUP BAG ALREADY!

When makeup has expired, the color can change and go on blotchy—but worse than that, "it can harbor all sorts of bacteria that you don't want near your skin or eyes," says makeup artist Laura Geller, founder of Laura Geller Beauty. To play it safe, replace mascara and eyeliner every three months, toss creams and liquids after a year, and chuck powders after two years. "It'll help if you write the date that you open a product on the tube or compact," Geller says.
