What Does the Period After Opening Icon Mean?
The period after opening icon (or PAO) is found on skincare products and holds the purpose of identifying the lifetime of product after the packaging has been opened.
It means that even if a product has an expiry date of 2 years, once the product has been opened it needs to used within the time displayed on the icon.
Below is an example of this icon, with 6M standing for six months. This means after opening, the product should be used within that six months, with any remaining product after this period discarded.
