Have an overflowing collection of nail polishes? We can’t blame you — there are so many dazzling seasonal and limited-edition collections, it makes sense why you’d want to collect them all. But just like your favorite mascara will run dry and your signature perfume may start to sour after a few years, nail polish has an expiration date too. Because we’re such huge nail polish enthusiasts, we wanted to find out exactly how long nail polish lasts, how to tell when the polish is expired and how to keep our favorite bottles fresher longer. Below, we turned to Jin Soon Choi, celebrity manicurist and founder of nail polish line JINsoon, and Tina Wang, owner of Lunula Salon in Brooklyn, New York. How Long Does Nail Polish Last?Both Choi and Wang say that nail polish will typically last about two years. However, Choi notes, “From my experience, it can last much longer provided you follow the sun and heat precautions and open the bottle as infrequently and for the shortest duration possible.”How to Tell if Your Nail Polish Is ExpiredThe Texture Is Sticky and Thick“The most obvious sign of expired nail polish is when the polish becomes thick,” says Choi. “You can tell because it clumps onto the brush and can't be readily distributed on the nail surface.” The nail polish may also look and feel sticky. You may be able to breathe new life into a thickened nail polish by adding nail polish thinner to the bottle and shaking well before applying. Otherwise, you can also try giving it “a good swirl” with the brush, says Wang. “If the texture is smooth with no solid bits or stickiness, the polish is likely usable.”  The Bottle Won’t Shake UpSome nail polishes, including those from Choi’s line, contain shaker beads, which she describes as “small, stainless steel ball bearings” that help mix up the nail polish inside the bottle. When you can no longer hear or feel the beads rattling when you shake up the bottle, that’s a sign your polish is getting thicker and may be on the verge of expiration. How to Make Nail Polish Last LongerTip #1: Limit How Long You Leave the Bottle OpenWhen you’re switching between nail polish shades or queueing up the perfect song to listen to during your DIY pedicure, make sure to close your bottle of polish. Choi says that every time you open a bottle of nail polish, the solvents inside the formula start to evaporate. “This is the main cause of nail polish getting thick and goopy,” she explains. Tip #2: Shake Up Separation“People sometimes mistake polish separation as a sign of polish being old and unusable, but the separation can happen to fresh polish too,” says Wang. “The separation happens from different densities of pigment and other product components.” Again, she says, give your nail polish a swirl and check if the consistency is thick, sticky or chunky. If not, it’s likely still OK to use.Tip #3: Keep Your Polish in the FridgeThe best way to keep nail polish fresher longer is to store it away from direct sunlight and heat. So, what better place to store it than in the fridge? “I have been refrigerating original samples of all my JINsoon polish since 2013 and can say firsthand that they still look true to their original color and viscosity,” says Choi. While you may not be able to stretch an extra decade of use out of all your favorite nail polishes, it’s still a smart way to keep the formulas from thickening. If you choose to refrigerate your nail polish, make sure to let it get to room temperature before you apply it to your nails.Don’t have the extra minutes to spare (or the extra room in your fridge)? A cool, dark corner in your room will also suffice. Tip #4: Use a Nail Polish ThinnerTo extend the lifespan of a thick, sticky nail polish, Choi recommends adding a few drops of nail polish thinner to the bottle and shaking vigorously before application. This bottle of nail polish thinner is available for less than $10 on Amazon. Tip #5: Curate Your Nail Polish CollectionAgain, while we understand the urge to collect every shade of pink, red and blue polish under the sun, sometimes less is more, especially when it comes to keeping your polishes fresh. Cut down on waste and save some money by keeping your collection minimal. “Invest in neutral colors and ones you especially love so that you don’t end up with too many options that you won’t have time to use,” says Wang. “At Lunula, we keep a similar mindset with a very concise product selection. By keeping product choices minimal and curated, we are able to fully use all polish bottles. This minimizes waste, which is essentially minimizing product expiration.” Classic Nail Polishes to Keep in Your RotationIf after reading through this list, you’ve realized a lot of your nail polishes are expired, don’t worry. These are the classic shades to refresh your collection with this year, from a universally flattering crimson hue to baby pinks, nudes and glitters.Essie Gel Couture in Rock the RunwayRed nails are a staple that will never go out of style, and Rock the Runway is one of our favorite shades.
