How long is the shelf life of concealer? Can I use it if it is expired?

Concealer can cover eye bags, dark circles, and some shallow moles. It can be seen that concealer has many functions. So how long is the shelf life of concealer in general? Can concealer still be used after it expires?

If it is unopened, the shelf life of concealer is quite long. Different products can have a shelf life of two to four years. However, you don’t buy concealer to collect it. You must open it and use it. If it is opened, the shelf life is six to twelve months. Of course, in actual use, we still need to analyze whether it is expired based on the specific situation of the product. If you find that the concealer is difficult to blend into the skin and begins to dry, clump, or moldy and smelly, you should throw it away decisively because it means it has expired.

Expired cosmetics cannot be used. After opening, cosmetics will be contaminated by bacteria and dust in the air, and some active ingredients will undergo chemical changes, producing substances that are harmful to the skin. Its shelf life will be greatly shortened, usually about 6 months. Considering safety and use effect, concealer that has passed its shelf life cannot be used.
