What is the difference between PAO and Expiration Date?

Period after opening (PAO) refers to the amount of time a product will remain stable and safe for use after it has first been opened. Expiration date (or “shelf life”) refers to the amount of time a product will remain safe for use, regardless of when it was opened. If the product is opened immediately, the PAO would indicate the new “safe period” for the product, if before the expiration date. All CaraGala products include a PAO symbol, indicating the number of months a product will remain stable and are stamped with an expiration date.
