Like almost every other product, skincare items like sheet masks have a specific shelf life. And unless you’re planning on layering your masks or vow to use them every single day, you may want to veer away from buying more than you think you can use. “If you have the option to buy something like face sheet masks in bulk, you may want to reconsider,” consumer analyst Julie Ramhold shared with BestLife. “Even if the price is excellent, if you don’t use them all before they go bad, you’ll have to toss out any that are left over. While they might not harm you to use, they also probably won’t provide any benefit by that point.”
And even if you think it would be harmless to use an expired sheet mask, some of them may have gone stale, developed an off-putting scent or color, or generally be uncomfortable to put on the skin. Vince Spinnato, a chemist specializing in personal care products, cosmetics, and fragrances, also told Allure that skincare such as sheet masks might contain ingredients that, when expired, can cause a negative reaction. “Ingredients break down over time and chemicals could become altered, so those with particularly sensitive skin might develop a mild rash simply due to the change in chemical composition,” he explained.
