How long is the shelf life of nail polish?

In life, there are many women who love beauty very much. They especially like to apply nail polish on their nails. In fact, some harmful substances contained in nail polish are very bad for the human body. Moreover, it is not easy to breathe with nail polish on the nails. It will feel like there is a thick layer of stuff making the nails very uncomfortable. However, there are still some people who enjoy doing this. So how long is the shelf life of nail polish?

The shelf life of nail polish is usually marked as 12 months. Generally speaking, unopened, properly stored nail polish has a shelf life of at least 18 months. If the storage conditions are appropriate, a shelf life of 24 months is not a problem.

How to identify expired nail polish

The texture of nail polish is the most direct way to determine whether it is expired. Compared with new nail polish, nail polish with an earlier production date will appear thicker, more prone to clumping, and more difficult to apply evenly when used. This is because over time, the various ingredients in the nail polish begin to clump together, and it is no longer easy to mix them together.

How to store nail polish

Like all other cosmetics, nail polish can have a longer shelf life and usable life if stored properly. First of all, nail polish needs to be stored away from light and in a cool place, because light and heat will cause the nail polish to dry out. Do not keep the bottle open for a long time each time you use it. After use, tighten the bottle cap and store it. Air entering the bottle will greatly shorten the service life of the nail polish. You can keep it clean by cleaning the mouth of the bottle with acetone. Rub the bottle before each use (do not shake it up and down) to allow the nail polish to be fully mixed before use.

Try to expose nail polish to the air as little as possible. After use, it is best to wipe off the remaining nail polish on the bottle mouth with a tissue and tighten the cap immediately to prevent the nail polish from evaporating. As long as it does not thicken or dry out, it can be used for 3-5 years. It is best not to use toxic, harmful and carcinogenic chemical nail polish. Yellowing of the nails is a minor matter. The serious problem is that carcinogens will be inhaled into the lungs, which is many times more terrible than smoking! It is best to use healthy, environmentally friendly, non-toxic and odorless water-based nail polish (there is a good Canadian brand), which does not contain any harmful chemicals and is not afraid of washing with water after drying. It is absolutely safe and healthy, and can also meet the needs of beauty lovers. Also, if the nail polish becomes thick, you can add a drop of water and shake it thoroughly. If it is still not thin enough, add another drop of water to dilute it until you are satisfied. Don’t waste it until it’s used up!
