Does Nail Polish Expire? Find Out When to Toss Yours

You’ve got a collection of nail polishes, right? Maybe there’s that glittery blue from last summer’s beach trip or the classic red you’ve sworn by for years.

Just like we check expiry dates on our favorite snacks, it’s worth pondering, “Does nail polish expire?” It might seem ageless, especially when the colors still pop, but let’s unlock the secrets of its longevity.

By the end of this post, you’ll know just when to keep or toss that bottle from three summers ago.

Does Nail Polish Expire?

Absolutely, nail polish does expire. While you might be wondering, “Where’s the expiration date?” nail polishes, unlike some pantry items, don’t typically come with a clear expiry date.

However, many do feature a PAO (Period After Opening) symbol either on the bottle itself or its packaging. Have you noticed symbols like 12M or 24M? These indicate how long the polish is expected to remain in good condition after opening.

The PAO symbol typically consists of a number followed by ‘M’, denoting the number of months the product is effective post-opening. For instance, ’12M’ suggests the polish has a lifespan of up to one year after being opened.

In optimal conditions—specifically, stored in a cool, dark place—an unopened polish can retain its quality for 5 to 8 years. Once opened, they usually last anywhere from 18 to 24 months. As for opened gel nail polishes, they tend to last between 24 to 36 months.

However, a bottle left in direct sunlight or not properly sealed can see its longevity reduced. Factors like sunlight exposure and fluctuating temperatures can accelerate the aging process of your nail polish.

It’s essential to note that even if a polish outlives its indicated PAO, it doesn’t necessarily mean it’s as good as new. Always be vigilant for signs that your nail polish is past its best.

Why Does Nail Polish Go Bad?

Did you ever think that tiny missteps could be the reason your nail polish loses its charm sooner than anticipated? Avoid these pitfalls, and your polish might just outlive its expected shelf life.

  • Cap Isn’t Tightly Secured: We’ve all been there. You’re chatting with a friend, and oops, you forgot to tighten that nail polish cap. A loose cap allows air to mingle with the formula, leading to potential evaporation of the polish’s solvents. So, whenever you’re done, double-check that cap!
  • Separation Inside the Bottle: Noticed strange layers in your polish? That’s the ingredients deciding they need some space from each other. It’s an SOS for your nail polish. Regular shakes can prevent this, but once they separate, getting the magic back is tough.
  • Light and Temperatures Changes: Sunny days are perfect for picnics, but not for storing your polishes. Sunlight, changing temperatures, or any direct heat can be a nail polish’s worst enemy. And, between you and me, the bathroom might not be the ideal place for them. Those frequent hot showers can cause temperature spikes.
  • Age of the Product: Simply put, the older the nail polish, the more likely it is to undergo changes in consistency. Even if it’s been stored in perfect conditions, its ingredients can naturally break down over time.
  • Contamination: If you’ve ever used a nail polish for nail art and dipped the brush into other substances (like glitters or pigments) and then back into the bottle, there’s a risk of contamination. This can introduce foreign particles and potentially bacteria, which might spoil the polish faster.
  • Frequent Use: Bottles that are used more often are exposed to air more frequently, every time they’re opened. This increased exposure can accelerate the thickening of the polish, especially if the bottle isn’t sealed tightly after every use.

How to Tell When Your Nail Polish Has Gone Bad

So, how do you tell if your nail polish is throwing up the white flag?

Check the Labels and Packaging

The “Period After Opening” (PAO) label is a quick reference. Typically found at the bottom of the bottle, this symbol indicates how many months the polish is expected to remain in optimal condition once opened. For instance, ’24M’ means the product is expected to last for up to two years post-opening.


Polish dyes and pigments can separate from the rest of the formula over time, leading to discoloration. While color separation can be a natural occurrence, due to varying densities of the ingredients, a noticeable change in the hue is a clear warning sign. Factors like exposure to direct sunlight or extremely high temperatures can further accelerate discoloration.

Texture and Consistency

Beyond mere appearance, the texture of nail polish is an unmistakable indicator of its condition. Separation can manifest as a clear distinction between the pigmented portion and the rest of the polish, often with pigments settling at the bottle’s bottom.

If shaking the bottle doesn’t homogenize the liquid or if the polish feels unusually thick, it’s probably past its prime. Furthermore, a gloopy or crumbly consistency indicates the evaporation of essential solvents in the polish.

Unwelcome Odors

An altered or strong odor is a definite sign that the nail polish needs to be discarded. Over time, some of the stable compounds in nail polish can deteriorate, giving rise to unpleasant smells. This is especially true for gel polishes, which are generally stored in opaque bottles; their scent becomes a primary means of gauging their freshness.

Difficulty Opening the Bottle

Difficulty in opening the nail polish bottle due to dried-out polish accumulating around the cap is a tangible sign of the polish’s decline. Not only does it indicate a breach in the bottle’s airtightness but also points to potential alterations in the polish’s composition.

Special Mention: Gel Polish

Gel polishes might present more challenges when it comes to determining their state, given their opaque bottles. A significant change in the original scent or issues related to setting under UV light are strong indicators that the gel polish is past its best.

How to Extend the Life of Your Nail Polish

You love your polishes, and they love you back. So, how can you keep the relationship going strong? Here’s how:

Storage and Handling Tips

  • Ideal Environment: Keep your polish in a cool and dark place, safe from the harsh rays of the sun or any direct heat. Bedroom cabinets can be an excellent choice!
  • Avoid Unnecessary Exposure: Refrain from opening the polish bottle unless you’re using it right away. Remember, nail polish starts its countdown to expiration once opened, so be mindful!
  • Cap It Right: A tight seal is essential! Make sure the cap is firmly screwed on, ensuring an air-tight fit. This not only maintains the polish’s consistency but also prevents unwanted chemical reactions and bacterial intrusion.
  • Shake It Up, But Gently: Ensure you shake or roll the polish bottle for about 30 seconds every couple of weeks. This keeps the formula consistent and prevents separation. However, avoid overzealous shaking, as it can introduce bubbles into the polish.
  • Maintain Cleanliness: Residue can be an enemy to a perfect seal. Before capping, ensure the bottle rim and the cap are free from dried polish. For a thorough cleaning, swipe them with a bit of non-acetone nail polish remover. This not only ensures an air-tight fit but also prevents future clumping or sticking.

Reinvigorating Old Polish

  • The Magic of Thinners: Over time, polish can thicken, but there’s a savior: nail polish thinner. A few drops can rejuvenate the consistency. However, use sparingly. Overusing can diminish the polish’s pigmentation. If the polish doesn’t restore after one or two attempts with thinner, it might be time to part ways.
  • The Revival Roll: If your polish has separated, simply roll the bottle between your hands. It’s a gentle way to remix the ingredients without introducing air bubbles. Remember, if the polish remains separated despite your efforts, it’s an indicator that its best days are behind.

By following these tips, you’ll ensure your nail polish stays in optimal condition for a longer time, ready to beautify your nails whenever you wish.

The Risks of Using Expired Nail Polish

Many might brush it off, thinking, “It’s just nail polish.” However, applying an expired polish can potentially compromise the beauty and health of your nails. Here’s why:

  • Compromised Application Quality: With time, nail polish loses its smooth consistency. An expired polish tends to become thicker, making the application uneven and challenging. Not only does it lose its vibrancy, but the polish might also fade, resulting in a lackluster manicure.
  • Short-lived Manicure: Fresh nail polish provides a long-lasting finish as intended by manufacturers. On the other hand, older polishes might start to peel shortly after being applied, making your manicure less durable.
  • Limited Physical Harm but Play Safe: While the chemicals in nail polish have antimicrobial properties, reducing the chances of contamination, it’s always prudent to prioritize your health. There isn’t a plethora of data regarding the tangible harm caused by expired polish. However, to eliminate any uncertainties, it’s recommended to opt for a fresh bottle when in doubt.

Frequently Asked Questions

Let’s address some common questions you may have regarding whether nail polish expires.

Is it OK to use expired nail polish?

Using expired nail polish isn’t harmful in terms of bacteria since the chemicals in nail polish are antimicrobial. However, the main concern with using expired nail polish is the degradation of its quality. Over time, polish can become thick, separated, and hard to apply. The color might also fade. It may result in a less-than-stellar manicure that may chip or peel soon after application.

How do you know if nail polish has gone bad?

Nail polish that has gone bad will typically exhibit one or more of the following signs:

  1. Separation: While it’s normal for the ingredients to separate over time, if you shake the bottle and the polish doesn’t mix back together, it has gone bad.
  2. Texture Changes: If the polish has become too thick, clumpy, or sticky.
  3. Discoloration: A noticeable change in the original color or faded color.
  4. Odor: A foul or unusual smell different from the typical solvent scent of nail polish.
  5. Application: It becomes challenging to apply smoothly onto the nails.
  6. Drying Time: Takes too long to dry or doesn’t dry properly.

Can you use nail polish from 10 years ago?

While it’s possible to use nail polish from 10 years ago, it’s not recommended due to the degradation in its quality. Over such a long period, the polish is likely to have experienced changes in texture, consistency, and color. The polish may not adhere to nails as effectively as when it was new, leading to a less-than-optimal manicure.

Can I use nail polish after 3 years?

It depends on the condition of the nail polish. If stored correctly (in a cool, dark place) and the polish hasn’t exhibited any signs of going bad (like those mentioned above), then it might still be usable.

However, remember that opened regular nail polish typically lasts around 18 to 24 months in optimal condition. After 3 years, even if it seems okay, the quality and finish might not be as good as when it was new. Always check its consistency, smell, and color before applying to ensure a good manicure result.


In conclusion, understanding the answer to “does nail polish expire” is crucial for every nail polish enthusiast.

This beauty staple, though enduring, does have its shelf life. Being attentive to its state and recognizing potential signs of expiration will ensure your manicures remain vibrant and long-lasting.
