Does Nail Polish Expire?

As with any other beauty product, it helps to know the lifespan of your nail polish if you want it to keep working hard for you. We’re here to help you figure out how long nail polish lasts and how to spot expired products (and the potential hazards of using them). With our practical advice, you’ll find out how to keep your nail polish collection in primo condition so that every manicure is as flawless as the first.

Does Nail Polish Expire?

Yes, nail polish expires. Typically, nail polish has a shelf life of about 18 to 24 months after opening, but it varies depending on the brand and formulation. Over time, the solvents in the polish can evaporate, causing the consistency to thicken and the ingredients to separate—all of which makes it really hard to apply smoothly.

Expired nail polish may lose its vibrancy, become more prone to chipping, and deliver an uneven finish. That’s why it’s important to regularly review your nail polish collection and toss any bottles that show signs of advanced age.

What Happens If I Use Expired Nail Polish?

Thickened, Clumpy Consistency

Expired nail polish often becomes thick and clumpy, making it a challenge to apply smoothly. This can result in a streaky or uneven finish, detracting from the look of your manicure.

Dull or Altered Color

The vibrant hue of nail polish can fade over time, leading to a dull or altered color. This means your favorite shade may no longer look as attractive or match your expectations.

Increased Chipping and Peeling

Old nail polish is more prone to chipping and peeling, which shortens the longevity of your manicure.

Reduced Manicure Quality

In general, using expired nail polish compromises the quality of your manicure. For the best results and for the health of your nails, regularly check and replace old nail polish.

How Can You Tell If Nail Polish Has Gone Bad?

Thick and Clumpy Texture: When nail polish becomes thick, clumpy, or hard to apply smoothly, it’s probably expired.
Separation of Ingredients: Noticeable separation of the polish into layers, with the pigments settling at the bottom and a clear liquid on top, indicates that the polish is past its prime.
Color Changes: If the color appears faded, dull, or different from its original shade, the polish may no longer be good.
Difficulty Mixing: If shaking the bottle doesn’t restore the polish to a uniform consistency, it’s likely expired.
Chipping and Peeling: If the polish chips or peels easily after application, it may have lost its effectiveness due to age.

Does Nail Polish Have an Expiration Date On The Packaging?

Nail polish usually doesn’t have a specific expiration date printed on the packaging, but many brands include a Period After Opening (PAO) symbol, which indicates how long the product is expected to remain usable after it has been opened. This symbol, often depicted as an open jar with a number followed by the letter "M" (so 24M for 24 months), offers a shelf-life guideline for the product once it has been exposed to air.

While the PAO symbol is a useful reference, it's just as important to rely on visual and sensory cues—like changes in texture, and color—to determine if the nail polish has gone bad. Observe these factors regularly to help ensure that your nail polish stays in optimal condition.

How To Store Nail Polish For Maximum Shelf-Life

Keep Bottles Tightly Sealed: Check that the cap is closed securely to prevent air from entering, which causes the polish to thicken or dry out.
Store in a Cool, Dark Place: Keep nail polish away from direct sunlight and heat sources, as exposure to light and high temperatures can degrade the formula.
Avoid Humidity: Store nail polish in a dry place to fend off moisture that can affect quality and consistency.
Store Upright: Keep bottles standing to stop spills and help the polish stay evenly mixed. Consider a nail polish organizer to keep your collection neat and safe.
Refrigerate for Longevity: For long-term storage, you can stash nail polish in the refrigerator. The cooler temperature can help extend shelf life.

When Should You Throw Out Old Nail Polish?

Throw out old nail polish when it shows signs of expiration: a thick, clumpy texture; a noticeable separation of ingredients that shaking doesn’t solve; if the color has faded, dulled, or changed; if the polish chips and peels easily after application. Looking for these telltale signs will help you maintain a polish collection that delivers great manicures, not to mention sidestep potential health risks.

Keep or Toss? Now You Know

Knowing the lifespan of nail polish and recognizing signs of expiration matter when it comes to maintaining healthy nails. By properly storing nail polish and checking it often for changes in texture, color, and smell, you can extend the shelf life of your favorite shades and expect a like-new mani or pedi every time. Getting rid of expired polish also safeguards against health risks…because no one’s got time for that.
