Do Murad products expire?
All Murad OTC (over-the-counter) products such as sunscreens, acne products and skin-lightening products (Salicylic Acid, Sulfur and Hydroquinone) have a two-year shelf life and an expiration date on the carton. Murad cosmetic products are validated to have a three-year shelf life.
There is a PAO (period after opening) symbol on Murad products that depicts an open cosmetics pot and is used together with a written number of months or years.
All Murad supplements have an expiration date stamped on the carton. Murad supplements have an expiration date based on the substantiation to support expiration. It could vary based on type and form of supplement.
As per the guidance for cosmetics in the U.S. and particularly label claims and expiration dating, there are no regulations or requirements under current United States law that require cosmetic manufacturers to print expiration dates on the labels of cosmetic products. It is left to the manufacturer to determine shelf life for products, as part of their responsibility to substantiate product safety.
International Murad expiration date standards follow that of the European Union (EU), which dictates the use of two different types of symbols.
PAO symbol: In the European Union, cosmetics products with a shelf life of at least 30 months are not required to carry a "best used before end of ..." date. Instead, there must be "an indication of the period of time after opening for which the product can be used without any harm to the consumer."
Hourglass symbol: For products with minimum durability less than 30 months a new “Hourglass” symbol is required.
