Do skin care products have an expiry date?
Expiry dates on the packaging of skin care had been replaced with a PAO symbol.
. The Period After Opening (PAO) symbol was introduced as a harmonised approach by the Cosmetics Directive in Europe for labeling the useable lifespan of cosmetic products. This symbol is displayed on the product container and normally looks like a jar with an open lid with a number next to it (eg, 12 or 24). This refers to the number of months you ought to keep and use the product for before throwing it away once opened. This number can appear either on or next to the open jar symbol.
