Can I use expired concealer?

I believe that every young woman who loves beauty has her own makeup bag, and there are a lot of cosmetics in that small makeup bag. Generally speaking, cosmetics can be used for a long time, and most cosmetics are expensive, so many women are reluctant to throw them away after the expiration date. Concealer is a must-have cosmetic for women, so can expired concealer still be used?

How much do you know about the shelf life of cosmetics?

Normally the shelf life of cosmetics is 3 years. The shelf life after opening can be as short as 3 months or as long as 2 years. Generally speaking, solid cosmetics with a single ingredient have a longer shelf life, while liquid cosmetics with complex ingredients have a shorter shelf life.

The main problem with cosmetics that have exceeded their shelf life is microbial contamination. After opened cosmetics are exposed to air for a long time, the active ingredients in them may undergo chemical changes, posing potential harm to the skin. Therefore, from the perspective of safety, effectiveness and comfort of use, it is emphasized that cosmetics should be used within the shelf life.

Concealer shelf life: 6-12 months

Liquid concealer is a breeding ground for bacteria. Of course, if it is not opened, the shelf life of concealer can reach 2 to 4 years, but no one buys concealer to use it as a decoration. Expired foundation will emit an unpleasant odor and change color, which means that the oil composition inside has changed and is very irritating to the skin.

If you find that the concealer is difficult to blend into the skin when you use it within the shelf life after opening it, or if the concealer has begun to dry out, clump, or become moldy and smelly, please throw it away without hesitation. It is not a big problem to try using expired lipstick once, but if you continue to use products such as concealer and foundation after they have expired, it is likely to cause skin allergies and damage the skin. Unopened liquid foundation can be stored for many years. Once opened, please use it up as soon as possible within six months to a year.

All cosmetics have a shelf life. Whether cosmetics beyond the shelf life can be used depends on the circumstances. For example, if concealer has an unpleasant odor, it is best not to use it, because anything you put on your face must be absolutely safe. If the concealer is the same as before it expires, it can still be used!
