How Long Does Makeup Typically Last?

We’ve all been there: you find the perfect foundation, fall in love with a limited-edition lipstick, or splurge on a luxury eyeshadow palette. But after a few months—or maybe a few years—a nagging question arises: Is this still safe to use?

Makeup doesn’t last forever. In fact, using products past their prime isn’t just a cosmetic issue; it can lead to skin irritation, breakouts, or even serious infections. Understanding the typical lifespan of your beauty products is key to keeping both your skin and your application routine healthy.

Here’s a general breakdown of how long common makeup products typically last after opening.

Mascara and Liquid Eyeliner: 3 to 6 Months

These are the most delicate products in your kit. Because the wand goes back and forth between the tube and your eyes, it’s a breeding ground for bacteria. Mascara has the shortest lifespan—typically three months. If it starts to smell funky, dry out, or flake, toss it immediately. Liquid eyeliner follows the same rule. Using old mascara is the fastest route to conjunctivitis or a stye.

Foundation and Concealer: 6 to 24 Months

The longevity here depends largely on the packaging. Liquid foundation in a pump bottle usually lasts 12 to 18 months because the product isn’t exposed to air or fingers as often. However, jar packaging (where you dip your fingers or a sponge in) shortens the lifespan to about 6 to 12 months due to repeated contamination. Powder foundations and concealers last longer—usually up to 18 to 24 months—as they contain less water, which inhibits bacterial growth.

Lipstick and Lip Gloss: 1 to 3 Years

Lipsticks (especially bullet formulas) are relatively hardy, typically lasting 2 to 3 years. You’ll know it’s time to say goodbye if you notice a waxy smell, a change in texture, or small beads of moisture on the surface (which indicate temperature damage). Lip gloss, on the other hand, has a shorter shelf life of about 12 to 18 months because the applicator introduces bacteria back into the tube.

Powder Products: 2 to 3 Years

Eyeshadows, blushes, bronzers, and setting powders have the longest shelf life. Powder formulas typically last 2 to 3 years because they lack the moisture that bacteria need to thrive. However, if you notice a hard layer forming on top (often called “hard pan”) that won’t lift with tape, or if the product starts to smell like crayons or mildew, it’s time to let it go.

The PAO Symbol

To take the guesswork out of the equation, look for the Period After Opening (PAO) symbol on the back of your product. It looks like a small open jar with a number inside (e.g., “6M,” “12M”). This tells you exactly how many months the product is good for after you break the seal.

Final Tips

If you want your makeup to last its full lifespan, store it in a cool, dry place—never in a steamy bathroom. Clean your brushes regularly to prevent transferring old bacteria back into the products. And if a product ever changes in smell, texture, or color, throw it out immediately, regardless of the date.

When in doubt, throw it out. Your skin will thank you.
