How Can You Tell if Nail Polish Has Gone Bad?

When nail polish has gone bad, you may not be able to use it anymore because it will be difficult to apply, and you would have no choice but to throw it out.

Some nail polishes you can still revive or restore when they have gone bad. If it has become clumpy, a nail polish thinner should work well to bring it back to its original consistency.

It is quite easy to tell if nail polish has gone bad. There are a couple of ways to tell.

Here are two ways to tell if nail polish has gone bad:

Check the appearance of the nail polish.

Most nail polishes come in a transparent bottle, so it is very easy to check their appearance without even opening the bottle. If the product has become thick and clumpy, then it means that it has gone bad.

If you open the bottle and lift the brush, you will see some nail polish sticking. You will also see that its consistency has turned thick, clumpy, and dry. If the nail polish has been exposed to high temperatures, its consistency is more watery.

When it has gone bad, it will be hard to apply as it does not go on smoothly as it used it.

Also, check the color of the nail polish. When nail polish has gone bad due to heat exposure, its pigments tend to separate from the mixture and become discolored.

If the color of your nail polish is different from when you first opened it, then it has gone bad.

Check the smell of the nail polish.

All nail polishes have pretty much the same smell.

This is because they are made of similar ingredients. So if you want to check if your nail polish has gone bad, then take a whiff.

Nail polish generally does not smell good – it smells of chemicals. If your nail polish has an unusual smell that is different from how it smelled when it was brand new, then it means that it has gone bad.

Does Nail Polish Go Bad After Sun Exposure?

Nail polishes are made of different substances that are not that stable, so they form a reaction when exposed to some elements.

When subject to sun exposure, nail polish can go bad.

Extreme heat from sun exposure can cause the solvents in nail polish to evaporate, making the product go bad and leaving it with a thick and clumpy consistency. And when this happens, the nail polish will be difficult to apply.

If you attempt to use it and apply it to your fingernails, it will not dry properly. The result will be a tacky manicure that smudges and gets nicked easily.

To prevent nail polish from being exposed to the sun, store it in a closed space that is not facing the sun. It should be kept at cool room temperature so its substances will not evaporate, causing it to go bad. In addition, always keep the bottle of nail polish tightly sealed.

At What Temperature Should You Store Your Nail Polish?

When storing nail polish, the rule is that you should keep it away from heat, light, and moisture. The best place to store it is in the bedroom or inside the closet.

The best temperature at which you should store your nail polish is 10 to 15 degrees Celsius.

With these temperatures, you can ensure that the nail polish does not go bad and retains its good quality and consistency.

Here are more tips on how to properly store your nail polish:

  • Keep the bottle of nail polish tightly sealed. This prevents air, heat, and moisture from forming a reaction with the product inside.
  • Always store the bottle in an upright position. When not in use, the pigments may separate, and it would be easier to mix them if the bottle of nail polish has been stored upright.
  • Keep the bottle away from direct sunlight. Exposure to direct sunlight can melt the product inside and cause it to become discolored.
  • Do not store your nail polish in the bathroom. The temperature and humidity in the bathroom are very inconsistent, especially if you have hot and cold showers, which can make the nail polish go bad.
  • You can store your nail polish inside the fridge – this is not necessary, but it helps. The fridge is a good place to store your nail polish as it is cool and dark. Plus, the temperature inside is constant.

The key to storing nail polish is to keep it away from high temperatures and sun exposure. If you keep these things in mind when storing opened bottles of nail polish, you can ensure that the product will not go bad easily.
