Have Your Beauty Products Gone Bad?

If you do a quick check of any woman’s bathroom, and chances are you’ll find jars of rarely used face cream, the dregs of a favorite powder blush, and at least one tube of lip gloss squeezed within an inch of its life. Whether unused, or consumed to the last drop, squeeze, or swipe, these cosmetics are taking up shelf (and makeup-bag) space because we want to get every penny out of the precious dollars we spent on them. But this hoarding habit has a catch: Beauty products do go bad. At best, they stop performing as well as they used to; at worst, they can cause irritations or infections.
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.

Toss-it time: Six months for liquids; two years for powders Insider info: You increase the odds of bacterial growth — and, hence, of breakouts or irritation — when you repeatedly dip your brushes and fingers into liquid foundation. Also, as it ages, foundation can go on unevenly, creating a streaky, inconsistent finish. Oils rise to the top, and the consistency thickens. Powders present less of a problem because bacteria can’t grow where there’s no water. However, over time, powders with botanical ingredients like aloe or jojoba can become harder to blend and are more likely to crumble, as their trace amounts of water evaporate. 

                                                    Mascara

Toss-it time: Three months Insider info:  A mascara tube is a dark, wet environment — the perfect breeding ground for bacteria.  Preservatives in a mascara only work for so long.  Plus, three-month-old mascara is a nonperformer. It’s chalky and powdery, and any lengthening or thickening fibers often separate from the fluid, so the mascara stops going on in a smooth, even coat. To avoid hastening the demise of your mascara, never pump the wand — that pushes air into the tube, causing it to dry out faster. Instead, slowly draw out and twist the brush to scrape the tube’s interior and pick up product. 

Eyeliner and Eye Shadow

Toss-it time: Liquid eyeliners, three months; cream eye shadows, six months; pencil eyeliners and powder eye shadows, two years Insider info: As they do with mascara, bacteria tend to flourish in liquid-eyeliner tubes, and the product dries out. Pencil eyeliners have a longer shelf life because you can create a fresh, clean surface each time you sharpen them. (Just be sure to regularly sanitize your sharpener with rubbing alcohol.) Powder shadows, like pressed powders, are less prone to contamination because they, too, lack water (if you wet them, toss after six months). But aging eye shadows have performance issues: They get packed down, making it harder to pick up pigment with your brush. 

Lipstick and Lipliner

Toss-it time: Lipstick and gloss, two years; lipliner, two years or more Insider info: Lipsticks’ water content makes them potential mini reservoirs of bacteria. No surprise, they also dry out with age. They will no longer look creamy on the lips.  Long-wearing formulas may have an even shorter life span since they often contain ingredients that evaporate more quickly than creamier formulas. Pencil lipliners, like eyeliners, may last a little longer since putting them through a sharpener removes the old surface. 

Nail Polish

Toss-It Time: One to two years Insider info: When polish expires, the consistency turns gooey or stringy.  Formulas are especially sensitive to temperature extremes and humidity, so avoid storing in the bathroom.

Skin Care

Toss-it time: Acne creams and other over-the-counter products that contain drugs are FDA regulated and usually carry expiration dates. But cosmeceuticals (products claiming to have anti-aging and skin-changing benefits) are not regulated, and once they’ve been used, they shouldn’t be kept for more than six months — or, if they’re in pump bottles, a year — says Wilson. Insider info: Some ingredients [such as vitamin C, retinol, and hydroquinone] degrade even more rapidly if they’re left in direct sunlight or exposed to air. Less frequently — but more alarmingly — certain products can actually become more potent over time. The reason: Active ingredients like retinol and glycolic acid become more concentrated as their bases degrade, separate, or evaporate. And when proportions change, your skin may get irritated. To prevent problems, store cosmetics properly, discontinue use after six months, and look for products that come in a pump, which helps keep air out. Another option that’s starting to hit shelves: special jars that dispense creams through a tiny hole or slit when you press the top (an internal “floor” rises with each push).

Sunscreen

Toss-it time: Six months Insider info: Sunscreens are FDA regulated, and though they usually have expiration dates of at least one year, that date indicates the purchasing time frame. When you open a tube, water may start evaporating, causing the formula to eventually become unstable. Once that happens, the ingredients are no longer evenly distributed, so you may get a lot in one dose, but nearly none in another. Protect your tube by storing it out of the sun.

Hair Products

Toss-it time: One year Insider info: Always close the caps of shampoos, conditioners, and styling products tightly. Otherwise, water and air can get in, breaking down the formulas or causing them to separate. Good news for hairspray users: Aerosol cans are the best product protectors going, so sprays should stay good even longer.

Simple Stay-Fresh Secrets

1. Wash and dry your hands thoroughly before putting your fingers into a product.
2. Avoid reinfection. Stop using all eye makeup if you have an eye infection and lip products if you have a cold sore. The exceptions: lipsticks, lipliners, and eye pencils, which can be shaved clean with a knife or sharpener. (Just cleaning with a tissue won’t suffice.)
3. Smell your mascara when you first purchase it. If you recognize that scent, you’ll know when it goes bad: Expired mascara often takes on a funny, chemical odor.
4. Choose a cotton-tipped swab or disposable sponge to apply makeup to a pimple — and avoid double-dipping. Going back and forth from the product to the affected area with your finger or a sponge can lead to contamination.
