How long is the shelf life of lipstick in general

Every exquisite girl needs a lipstick, and women must choose relatively expensive lipsticks when choosing lipsticks, because human lips are directly related to the uterus. If you use some inferior lipsticks, it is likely to cause damage to the uterus. Moreover, the use time of lipstick is relatively long, so it is also worth choosing a better one. So how long is the general shelf life of lipstick?

The shelf life of lipstick is generally about three years, but it may vary depending on the brand.

Once the lipstick is opened, it comes into contact with oxygen and the environment, and its shelf life will be shortened. Generally speaking, unopened lipstick is fine within three years, but after opening it may be shortened to two years. Although some lipsticks may look fine on the surface, they may have deteriorated “inside”, so don’t use them.

Symptoms of lipstick deterioration

1. Lipstick is overflowing. Some people also call this phenomenon "sweating". If lipstick is not stored properly, such as in a hot or humid environment, the quality of the lipstick will deteriorate and liquid may overflow.

2. The lipstick has an oily smell. This phenomenon is more common in high-end lipsticks and is caused by rancidity and oxidation. Generally speaking, some high-end lipsticks will add natural ingredients such as high-grade grape seed oil and jojoba oil, which can easily produce a large amount of unsaturated fatty acids. When rancidity and oxidation occur, oily odors appear.

3. The product has exceeded its shelf life. Generally speaking, the shelf life of unopened lipstick is three years, while the shelf life of opened lipstick is less than two years. If the period has expired, do not use it again even if no problems are apparent.

The shelf life of lipstick depends on the situation

The shelf life of lipstick is divided into opened and unopened. Generally, the shelf life of opened lipstick is half a year to one year, while the shelf life of unopened lipstick is about three years.

Specific date

The shelf life of the lipstick will be written on the outer packaging of the lipstick, but this shelf life refers to the unopened lipstick. Therefore, once the lipstick is used, its shelf life will not be as long as written on the packaging.

How to tell if lipstick is expired

You can smell it and see the color. If the taste hasn't changed and the color remains the same, then it hasn't expired. If lipstick goes bad, the oil in it will oxidize and have a very noticeable smell.
