Does Makeup Expire? How to Tell When It’s Time to Toss Your Beauty Products

Ever opened your favorite lipstick or mascara only to wonder if it’s still safe to use? You’re not the only one. Many of us hold onto makeup products far longer than we should—sometimes because they still look okay, or because we simply can’t part with our favorite shades. But here’s the truth: makeup does expire, and using expired cosmetics can do more harm than you think.

In this guide, LouisianaMart breaks down how to identify expired makeup, the average shelf life of different products, and how to make your beauty routine safer, fresher, and more effective.

Why Makeup Expiration Dates Matter

Every product you use—foundation, mascara, lipstick, or eyeshadow—contains ingredients that break down over time. These changes can affect texture, color, performance, and most importantly, safety. Using old makeup increases the risk of skin irritation, eye infections, and breakouts, even if it looks perfectly fine on the surface.

Think of it this way: just like food, makeup has a shelf life. The better you understand it, the easier it is to keep your beauty routine both clean and effective.

How to Find Makeup Expiration Dates

You don’t need to be a beauty detective to figure this out! Most makeup products come with symbols and markings that tell you when they expire. Here’s what to look for:

1. The PAO Symbol

The “Period After Opening” symbol looks like a small open jar printed on the packaging. Inside the jar, you’ll see a number like “6M” or “12M,” which stands for how many months the product stays safe after you’ve opened it. For example, “12M” means it’s good for one year after opening.

2. Batch Codes and Expiry Stamps

Some brands include batch codes or direct expiration dates—usually printed near the barcode or crimped edge of the tube. You can even use online batch code checkers to confirm the manufacturing date.

At LouisianaMart, we make sure our partner brands include clear labels so you always know when your beauty products are at their best.

Typical Shelf Life of Common Makeup Products

Here’s a general guide to help you gauge how long your favorite items typically last once opened:

💡 Pro Tip: If you can’t remember when you opened a product, it’s safest to replace it—especially for anything that goes near your eyes or lips.

Signs It’s Time to Toss Your Makeup

Even if the expiration date hasn’t passed, your makeup might show signs that it’s gone bad. Trust your senses—your eyes, nose, and fingertips can often tell you before the label does.

Here’s what to look for:

• Strange Smell: A sour, musty, or chemical scent means it’s time to say goodbye.
  

• Texture Changes: If your foundation starts to separate, your mascara feels dry, or your lipstick turns gritty, toss it.
  

• Color Fading or Darkening: Products that lose vibrancy or look uneven often indicate chemical breakdown.
  

• Poor Performance: If your makeup doesn’t blend, set, or apply like it used to, it’s likely expired.
  

Tip from LouisianaMart: When in doubt, throw it out. Your skin’s health is worth more than one last use.

How to Store Makeup for Longer Shelf Life

Proper storage can significantly extend your makeup’s freshness and performance. Here’s how to make your products last longer:

1. Keep It Cool and Dry: Store makeup in a cool, dry place away from sunlight and humidity (yes, that means avoiding bathroom storage!).
   

2. Seal It Tight: Always close lids and caps properly after each use.
   

3. Clean Tools Regularly: Brushes and sponges collect bacteria—clean them weekly.
   

4. Avoid Sharing Makeup: Especially products for eyes and lips, which are more prone to bacteria transfer.
   

5. Wash Your Hands Before Application: Keeps germs out of your favorite formulas.
   

At LouisianaMart, we carry brands that prioritize hygienic packaging and product safety—so your beauty essentials stay fresher, longer.

Why It’s Important to Replace Expired Makeup

Using expired products isn’t just a matter of performance—it can impact your health. Here’s what can happen if you keep using old makeup:

• Eye Infections: Old mascara or eyeliner can harbor bacteria that lead to redness or irritation.Skin Breakouts: Expired foundation or blush can clog pores and cause acne.
  

• Allergic Reactions: Ingredients that have degraded may irritate sensitive skin.
  

• Dull Results: Old formulas lose their pigment and effectiveness, making your look less vibrant.
  

Refreshing your makeup bag regularly keeps your skin healthier and your confidence higher. Plus, it’s a great excuse to try something new!

Frequently Asked Questions About Makeup Expiration

1. Does unopened makeup expire?

Yes, it does. Even if sealed, makeup ingredients can degrade over time. Most unopened products last between 2–3 years, depending on storage conditions. Always check for a printed expiration date or batch code.

2. Can I use expired makeup if it looks and smells fine?

It’s best not to. Even if it seems okay, the product’s formula and preservatives may no longer be effective, leading to irritation or poor results. Always err on the side of caution.

3. Do natural or organic products expire faster?

Typically, yes. Products with fewer preservatives have a shorter lifespan. Store them as directed and use them within the recommended timeframe.

4. How can I remember when I opened my makeup?

Use a small label or write the date on the packaging with a marker. It’s a simple trick that saves you guesswork later.

5. What should I do with expired products?

Dispose of them responsibly. Avoid flushing liquid products down the sink—check your local recycling options or cosmetic disposal guidelines.
