Unopened products maintain their quality and perform as expected for approximately two years when stored at room temperature. Once opened, it’s advised to use the product within the specified timeframe indicated by the Period After Opening symbol, which varies by product. This symbol is used as a guideline to indicate the number of months the products should be used within after you have first opened it, provided the product has been stored under normal conditions and not exposed to extreme temperatures. The Period After Opening symbol looks like a small jar with a number and the letter M inside it. This can be found on the bottom or the back of the product. The number found next to the letter M indicates the recommended number of months the product should be used within after opening. For example, a product marked “12M” should be used within twelve months of opening. Non-SPF products do not have an expiration date unless otherwise indicated.
