"There are no U.S. laws or regulations that require cosmetics to have specific shelf lives or have expiration dates on their labels, but there is a time frame for when they should be used after opening. We recommend using the product 90 days after opening maximum. Unopened and kept in a cool, dry environment away from direct sunlight, some products can last up to 2 years. While using older products may not be relatively harmful, the product may have lost some potency and may not be as effective as a newer, fresher product."
