When Your Skin-Care Products Expire

It's easy to forget that many active ingredients—found in anti-aging creams, acne treatments, peels, and more—are surprisingly fragile. It's only a matter of time until oxygen and heat render them useless.


ANYTHING IN AN AMPOULE
Toss after: One day, since formulas packaged in these single-use tubes typically contain vitamin C or E or other ingredients that oxidize upon exposure to air.

HYDROQUINONE CREAMS
Toss after: They turn brown (usually around the two-month mark). Choose products in an airtight pump and store them in the fridge, which will add another month to their life span.

SWIPE-ON PADS (GLYCOLIC PEELS, ACNE TREATMENTS)
Toss after: Two months, unless they're packaged individually—by then most will start drying out.

PEELS AND MASKS
Toss after: Three months. At that point their buffering agents can start to evaporate, making active ingredients such as glycolic and fruit acids more potent (and irritating).

ACNE PRODUCTS
Toss after: Four to six months. Benzoyl peroxide and salicylic acid, two of the most common pimple fighters, decay quickly. Keep them in the refrigerator for maximum potency.

RETINOID CREAMS
Toss after: Nine to 11 months, when their collagen-producing power starts to conk out.

SUNSCREENS
Toss after: One to two years—it varies, so check the expiration date on your tube. Wechsler suggests keeping sunscreen in a cooler when at the beach and trashing any tube that's been left sitting in a hot car.

MOISTURIZING CREAMS
Toss after: One year. Though a plain moisturizer without anti-aging ingredients will last well past this mark, you can contaminate it by dipping repeatedly into the jar.

GRAINY SCRUBS
Toss after: Two years. These hearty exfoliants are made of virtually indestructible materials, but an open tub will still become a breeding ground for bacteria over time.

The 10 Commandments of Lipstick

Step aside, gloss. Lipstick is back in a big way, making mouths look strong, rich, and thoroughly refined. Here, the rules for doing lipstick right, right now.



1. START FRESH
Start fresh. Exfoliate lips once or twice a week (Cantello uses a mix of salt and almond oil), then follow with balm.

2. AVOID TOO MUCH SPARKLE
"Shimmer can look cheap," says makeup artist Troy Surratt. Look for lipsticks with a creamy finish. "Light reflection should come from moisture in the formula, not metallic pigments," he says. Two hydrating options: Dolce & Gabbana Passion Duo Gloss Fusion Lipstick and Clinique Butter Shine Lipstick.

3. FIND THE RIGHT BRIGHT
Choose a bright shade based on your lips' natural color—not your skin tone. Women with pale lips look best in cherry red or coral; for naturally reddish lips, try hot pink, orange, or cranberry; for dark lips, brick red and burgundy are ideal. Try Yves Saint Laurent Rouge Pur Couture in 01 (for pale lips), M.A.C. Lustre Lipstick in Lustering (for reddish lips), or L'Oréal Paris Infallible Le Rouge in Bold Bordeaux (for dark lips).

4. LOOK GOOD NUDE
The prettiest nude lip color is slightly brighter or deeper than your skin tone. If you're pale, look for something with a hint of pink, like Burberry Beauty Lip Cover in Nude Rose. Those with yellow or olive undertones or dark skin look best with sandy beiges, like CoverGirl LipPerfection Lipcolor in Delish.

5. AVOID THE VAMPIRE EFFECT
Blue- or black-based shades that are too dark can be severe, aging, and even a little scary. Look for lipsticks with berry undertones instead.

6. DON'T WORRY ABOUT LINER
Liner is no longer a must—today's lipsticks don't bleed," says Surratt. To enhance your Cupid's bow or add symmetry, use a pencil that matches your lips, not your lipstick.

7. SOFTEN THE EDGES
Careful application is good; clinical precision isn't. Just smudge the border of your lips slightly.

8. START IN THE MIDDLE
When applying any shade of lipstick, start at the center of lips and blend color out toward the corners of your mouth. (Never apply it directly to the corners of your mouth—it will look clownish.)

9. DON'T OVERDO IT
Prevent a strong lipstick shade from looking heavy by swiping it on just your bottom lip, pressing lips together, and using your finger to distribute the color over your mouth.

10. BLOT, BLOT, BLOT
To make your lipstick last longer, apply it straight from the tube, blot with a tissue, then swipe it on again. "Blotting will create a base, and the second coat adds shine and coverage," says Surratt.
