All products have at least a 2-year shelf life (before opened) unless otherwise stated on the package. We guarantee all products purchased from the website are fresh. The only products with a true expiration date are our acne products, nutritional supplements, and suncare products. All others have a container symbol printed on the back of each container which has a number followed by the letter M (e.g. 12M, which stand for 12 months). This is the amount of time the active ingredients will be at their highest effectiveness after it is first opened. We hope this clarifies your concerns about freshness, and, would like to further reiterate that all of the products we sell are fresh and at their maximum effectiveness.
