How long does lipstick expire?

Lipstick is a kind of cosmetic that most women have, and its shelf life is also very long, but this does not mean that lipstick has no shelf life. Generally speaking, the shelf life of lipstick is three years. If it is not stored properly, its shelf life will be shorter. Using expired or deteriorated lipstick can cause great harm to the human body. Therefore, female friends must understand clearly how long lipstick will expire and what to do when lipstick expires!

1. How long does it usually take for lipstick to expire?

Generally speaking, the shelf life of lipstick is three years. Because lipstick is mainly made of beeswax and oil, the chance of deterioration is not very high if it is stored in a cool and dry place according to the correct method.

If not stored properly, it will easily soften and produce an unpleasant odor after being exposed to sunlight and high temperature radiation, especially dark lipstick. Do not use lipsticks that have a bad smell after oxidation, as they will increase the risk of dry lips and breakage, and may also allow toxic spoiled substances to enter the human body.

If you want to extend the shelf life of your lipstick, try to place it in the refrigerator's fresh-keeping layer after each use.

2. What to do if your lipstick expires

1. How to deal with expired products: Lipstick is a must-buy cosmetic for many girls, and there are so many colors of lipstick. Many girls will accidentally buy too much, and if they can't use up all the lipstick, it will expire. When faced with expired lipstick, most people would choose to throw it away, but in fact, expired lipstick can also be turned into treasure. For example, you can use expired lipstick as a crayon for painting, or you can apply a layer of lipstick on tissue paper to wipe silverware, then use a sponge dipped in detergent to wash it off to remove black stains.

2. It is best not to use expired lipsticks: Some expired lipsticks still look good, so some people can't help but continue to use them. However, this practice is not advisable, because some chemical ingredients are added during the production process of lipstick. After the shelf life, these chemical ingredients may deteriorate and produce harmful substances. Continued use may cause allergies and redness, swelling and ulceration of the lips. Therefore, it is recommended that you try to avoid using expired lipstick.

3. The harm of lipstick

1. The lanolin in lipstick has a strong adsorption capacity. Dust, bacteria, viruses and some heavy metal ions floating in the air are adsorbed on the lips and will directly enter the body as we eat.

2. Lipstick contains heavy metals, preservatives, etc. Long-term intake by the human body may lead to chronic lead poisoning, causing anemia, abdominal pain, acute renal failure, brain neuropathy and other problems.

3. Carcinogenic. Lipstick contains coal tar dyes, preservatives, antioxidants BHA, etc., which are all carcinogens. Intake of a certain amount will harm your health.
