Generally, most SK-II products have an approximate shelf life of six to twelve months after opening. This time frame ensures that the products maintain their efficacy and safety for use. It is advisable to pay attention to any specific storage instructions provided on the product packaging and to keep products in a cool, dry place away from direct sunlight.
