The production date of Armani lipstick can be viewed through the product batch number, and the specific method is as follows:

1. Find the batch number on the product package, which is usually located at the bottom of the bottle or on the side of the bottle.

2. Interpretation of batch number: The batch number of Armani lipstick usually consists of numbers and letters, such as "GA0 123" or "PC5J02".

3. The first digit indicates the year of production: "2" means 20 12, "3" means 20 13, and so on.

4. The second to fourth digits indicate the date of production: for example, "0 12" indicates the 12 day when the production date is 20 12.

5. Some batch numbers may have redundant letters or numbers, usually the code of the production factory or production line, which has nothing to do with the production date.
