How Long Do Sheet Masks Last?
Unfortunately, like every other product on the market, sheet masks have an expiration date, as stated on the packaging. While it is generally not recommended to use expired products, some masks can still be used six to eight months after, depending on whether the package was opened or not.
Essentially, unopened sheet masks aren't exposed to the same atmosphere and potential bacteria growth as already opened masks. Sometimes, when the product's ingredients are exposed to oxygen and bacteria, the mixture can cause more damage to the skin than good.
