Foundation: 3-6 months
Concealer: Wand applicator concealers should be tossed within 6 months since they’re likely to grow bacteria. Stick, twist-up tubes, or compact concealers can last up to 12 months, especially if you use a makeup brush to apply the product.
Pressed powder cosmetics: Facial powder, blush and eyeshadow should be thrown out after one year. If you get an eye infection, however, you’ll have to toss out any eyeshadow you’ve used, to avoid re-infecting yourself.
Lip gloss and lipstick: 1 year
Mascara: You should always replace mascara after 3 months. And toss it immediately if it becomes dry, or you develop an eye infection. Remember: Never, ever
share mascara!
Eye and lip pencils: If you sharpen them every few days, makeup pencils can last a year or longer. It’s time to trash them when they become dry, crumbly, and hard to apply.
All-natural cosmetics: Because these products do not contain preservatives, they should be used or discarded within 6 months.
Here are some more tips that will help you make the most of your makeup:
1. Don’t ever share cosmetics.
2. Don’t put your fingers into the product. Use the applicator provided, or a makeup sponge.
3. Keep containers tightly closed, and store them in a cool, dry place.
4. Don’t use water or saliva to ease the application of a product. Doing so introduces bacteria into the product, which can cause a host of problems.
5. Immediately toss the product out if there is a change of color, texture, or consistency; if the ingredients settle or separate; or if an odor develops.
