The three markings may be close to each other, but they answer different questions. The term helps assess the shelf life, PAO refers to the period after opening selected cosmetics, and the batch identifies the series. It's a good idea to keep them together with the full product name.
Don't confuse the date with the code
The batch number may look like a string of digits, but does not have to be a date. Don't try to decipher it according to another brand's diagram. If the marking is illegible or questionable, show the photo to the manufacturer or seller. It is also helpful to know where the code is located on the packaging.
How to read PAO
The open jar symbol with the number of months refers to the period after opening the cosmetic, when such marking is applicable. It is not an automatic extension of the expiry date. Not all types of cosmetics require identical markings. Don't assign a universal 12 months to each bottle based solely on your experience with the cream.
Save the opening moment
A short note on the packaging takes the guesswork out of it. If you pour the product, you may lose important labeling and storage instructions. It is better to keep the original box or a clear photo of it. Changes in appearance or smell are not used to set a new date on your own.
Why the party helps in contact
When asking about the recipe, labeling or problem with the product, please provide the exact name, capacity, batch and date. This is much more precise than the brand itself. Do not mix data from several packages. Thanks to this, the answer may refer to a specific product instead of the manufacturer's general offer.
