How long does a tube of mascara last?

In our lives, many people say that if mascara is not used frequently for a period of time, it will become dry, which makes it inconvenient to make it protruding again. In fact, the cosmetics used by women in life are the same as the food we eat. They all have a shelf life. If they are opened for too long, they may deteriorate even within the shelf life. Therefore, mascara should be used up as soon as possible after opening. So how long can a mascara be used?

1. How long can it be used before opening?

If it is unopened, the mascara can be kept for 3 years, but for safety reasons, it is recommended to use it up within one to two years.

2. How long can it be used after opening?

As for opened mascara, if you want to achieve obvious results, it is ideal to use it up within three months. If the mascara has been opened for half a year or more than a year, it will start to dry out and the final effect will be much worse than at the beginning.

3. Misconceptions about mascara

Usually, three to four years is the general shelf life of cosmetics, which often misleads many girls into thinking that a tube of mascara can be used for 3-4 years. In fact, this can only be achieved under good storage conditions. But once opened, this storage time is no longer appropriate. Generally speaking, it is not recommended to use mascara after three months of opening.

4. Reasons why mascara cannot be stored for too long

This is mainly because mascara is kept in a dark and humid environment for a long time, and after coming into contact with bacteria in the air, it will grow rapidly, increasing the risk of eye diseases. So I suggest you don't use it. Eyes are very important to girls. How can you bear to hurt them?

5. How to deal with air-dried mascara

Of course, over time, the mascara will dry out. At this time, we can use some methods to make it return to its previous appearance. For example: add vitamin E oil (or use olive oil or baby oil instead) into the bottle, put in eye drops, soak in hot water, and even use perfume.
