The ‘best before’ measure of your Aesop product is determined by the time of opening. The jar icon on the side of the label indicates the number of months the product will be at its best once open. For example, 12M equals one year from date of opening, 9M equals nine months from the date of opening.
Generally speaking—unless a shorter expiry date is printed on the product—Aesop products have a recommended shelf life of at least 36 months after manufacture with additional time as specified in the Period After Opening (PAO), which varies by product. Beyond this point, the aroma and texture of the formulation may vary, and its effectiveness—particularly relevant for active ingredients and sunscreens—may decrease. For best results, we recommend prompt initial use and observation of product specific storage recommendations.
