Most of us buy in bulk when grocery shopping or purchasing beauty products to avoid frequent trips to the store. However, sometimes products can sit around unused for a while, making us question if they’re still safe to use. A common question people have is whether unopened mascara expires.
Yes, mascara can last for a few years if unopened, but it will eventually expire. For those who keep their makeup for long periods, it’s useful to know how to tell if mascara has gone bad.
Cosmetic products, including makeup, come with expiration dates. These dates can be found on the packaging or the product itself. Let’s look into the shelf life of mascara and how to determine if it has expired.
How Long Does Unopened Mascara Last?
Generally, once opened, mascara lasts about 2 to 3 years. Even if it doesn’t visibly expire, the preservatives lose their effectiveness, allowing bacteria to grow. Mascara, being water-based, is particularly susceptible to bacteria. Therefore, it’s important to discard mascara if it’s been open for too long. Unopened mascara can last up to two years if stored at room temperature. Once opened, you should throw it out after four to six months.
What Is the Shelf Life of Unopened Mascara?
The shelf life of unopened mascara varies by brand and type, ranging from a few months to three years. While some brands use preservatives to extend shelf life, others do not. The expiration date listed on the package indicates how long the product can be used safely and effectively. After opening, contamination by bacteria can lead to eye infections.
How to Tell If Mascara Has Gone Bad
Mascara can spoil if not stored properly or if it becomes contaminated. Here are some signs that your mascara may be expired:
1. Change in smell: Over time, ingredients like castor oil and glycerin can develop an off-putting smell.
2. Change in texture: Mascara can thicken and form gooey clumps.
3. Examining the bottle: Look for any discoloration or leakage.
4. Change in consistency: Thicker than usual or clumpy texture indicates spoiling.
5. Clumpy and crumbly wand: Dried-up bits on the wand suggest the product has degraded.
6. Dry and stiff wand: Indicates possible bacterial growth and should be discarded.
7. Bubbles in the tube: Air introduced into the tube can cause bubbles, a sign it’s time to toss it.
8. Eye irritation: If it causes itching, burning, or swelling, stop using it immediately.
Is It Safe to Use Expired Mascara?
Using expired mascara can be risky, especially for those with sensitive skin. It can cause eye infections and inflammation. The biggest concern is bacteria, which can spread and lead to infections, particularly in people with compromised immune systems or contact lens wearers.
Can You Use Unopened Old Mascara?
You can use unopened old mascara, but there’s a risk of bacterial contamination. Even with preservatives, the risk of infection increases over time. For regular users, mascara should be replaced every three months.
How Do You Store Unopened Mascara?
Store mascara in a cool, dry place away from direct sunlight and heat. Ideally, keep it in its original box or a well-sealed container to prevent moisture from getting inside.
What Happens When Your Mascara Expires?
Expired mascara won’t harm you immediately, but it does lose its effectiveness. The preservatives can become irritating over time, which might cause breakouts or irritation.
Can Unopened Mascara Dry Out?
Yes, even unopened mascara can dry out due to evaporation. To prevent this, store it properly and avoid opening it until necessary.

2. L’Oreal Paris Voluminous Lash Paradise Waterproof Mascara

How Long Should Mascara Last?
Mascara should last about three months after opening. If it becomes clumpy, flaky, or dries out, it’s time to replace it. Likewise, if it starts smelling bad or causing irritation, discard it and get a new one.
Final Note
All mascara, opened or unopened, will eventually expire. Proper storage can extend its life, but it should still be rotated every few months to avoid drying out.
