The method to check the production date of Givenchy lipstick can be done by following these steps:
1. Observation location: The production date of Givenchy lipstick is usually marked at a certain position on the bottom or body of the cosmetic bottle, especially at the bottom of the outer shell, which needs to be carefully searched.
2. Interpretation of batch number: The production date of Givenchy lipstick is represented by a 4-digit batch number, which is composed of spray code letters and numbers. Among them, the first digit represents the year, for example, "8" represents 2018, "9" represents 2019, and so on. The second letter represents the month. There are multiple versions of letter representation for months, but common versions include starting from N or starting from A. The last two digits represent the specific production batch or date of the month, and for consumers, the main focus should be on the first two digits.
3. Determine shelf life: Givenchy lipstick typically has a shelf life of three years when unopened. Once opened and used, the shelf life is shortened to about one year. While checking the production date, it is also important to consider the usage and storage status of the lipstick to avoid using expired products.
Due to slight differences in the representation of production dates between different batches or versions of Givenchy lipstick, it is recommended to interpret them in conjunction with the batch number on the specific product. At the same time, some cosmetics production date query apps can also be used to assist in judgment, such as the True Self app, Weijian app, Beautiful Practice app, etc. These apps usually provide more accurate and convenient query services.
