If a product is unopened, the shelf life is up to 3 years. Make sure to keep it in a dry place, away from direct sunlight (not that we get much here). Once opened and stored correctly you`ll need to refer to the `period after opening` symbol on the back of the label. This is a diagram of an open jar with a number next to it. This refers to the number of months the product will last after opening provided it’s properly closed and stored after each use.
