Shelf life varies from product to product. We recommend you consult the Open Jar symbol on packaging to determine how long a product will maintain its freshness after it has been opened. For example, an Open Jar symbol with “12M” indicates that a product will function as intended for 12 months after it is opened assuming normal use and storage. While there may not be anything wrong or unsafe once a product has passed this time frame, we can no longer be certain our strict standards of quality are satisfied and request that you no longer use the product.
