FREE: Meaningful Beauty

"Unopened, well-formulated cosmetics can remain stable for a couple of years at room temperature," says Ni'Kita Wilson, a cosmetic chemist at Cosmetech Laboratories in Fairfield, NJ. "But the clock starts once you bring a product home and open it. When air hits the formula, certain ingredients start to oxidize and degrade." What's more, every time you touch your makeup or skin-care lotions and potions, you transfer germs to them — and, subsequently, to your face. Heat and humidity, which promote the growth of mold and yeast, are factors, too. That's one reason the bathroom, though convenient, isn't the ideal spot to store cosmetics. (High levels of airborne bacteria can contaminate beauty products, too.) A better place: a cool, dry linen closet.

Beyond the obvious signs — dried mascara or separated foundation — it can be tough to tell when something's past its prime. (U.S. labeling regulations don't require an expiration date on most cosmetics.) So read on for easy, expert, beauty-protecting tips on when to throw away what.

These have never been open and in a cool dry area in my closet shelving. Hope this helps more .
