How long is the shelf life of an unsealed lipstick

In life, many women like to put on makeup, and for some more straight men, a woman wearing lipstick is equivalent to putting on makeup. Every exquisite woman will have one or several high-end lipsticks, but because lipstick is used less frequently, sometimes when you buy a lipstick, the shelf life expires before you finish using it. This makes people feel a little regretful. So how long is the shelf life of an unsealed lipstick?

1. Unopened

The shelf life of unopened lipstick can be said to be quite long. The international standard is five years, and the domestic standard is three years. So how should you store unopened lipstick?

1. Place in a cool and dry place.

2. Take certain protective measures in extremely cold or hot conditions. For example, fairies in Northeast China must put their lipstick in a heated room in winter, while fairies in Hainan must put their lipstick in the refrigerator in summer.

2. Unpack the lipstick.

Although there is only a little bit of lipstick, the fairies' mouths are even smaller. Even if you apply it every day, it may take a year or two for a lipstick to run out. How could a beauty-loving fairy have only one lipstick? And what should she do with those unpacked lipsticks?

1. Place lipsticks in a clean cosmetic bag to avoid mixing with eyebrow pencils, eyebrow powders and other debris.

2. Take protective measures in extreme weather conditions. Do not put lipstick in your pocket as the temperature in your pocket is high and may cause the lipstick to deteriorate.

3. Giving roses to others will leave a lingering fragrance on your hands. It is also a good choice to give them to friends and relatives.

Lipstick is a girl’s “good friend” and should be treated with care. Even if it has a long shelf life, it should be used as soon as possible, especially once it has been opened. Have you gained anything after reading so many methods of maintaining lipstick today? Collecting lipstick is a hobby, but maintaining your own lipstick is an art.

1. The shelf life of general cosmetics is between 2 and 3 years, and lipstick is no exception. If it is lip gloss, the shelf life on the makeup refers to the storage period, and it generally has a shelf life of about one year after opening.

Therefore, girls should pay attention to the production date or shelf life on the label when purchasing, and try to buy those produced in the same year.

2. The main ingredients of lipstick include wax, oil and pigment. The basic ingredients are inseparable from Vaseline and wax, but now there are new formulas that do not contain wax. Antioxidant ingredients such as vitamins A and E, as well as SPF sun protection, are selling points of popular lipsticks.

3. Oils and waxes have strong adsorption properties and can adsorb harmful substances such as dust, viruses, bacteria, etc. in the air onto the oral mucosa and enter the body with food when people are not paying attention. Most of the dyes commonly used in lipsticks are non-food pigments that are harmful to the human body. Experts have confirmed through experiments that some inferior dyes also contain carcinogenic chemicals. Therefore, lipstick is actually a complex chemical substance, and there are hidden dangers behind its bright colors that people are not aware of.
