To query the production date of Lisu facial mask, you can follow the steps below:
1. Check the product package: carefully check the outer package or box of Lisu facial mask. The production date is usually clearly marked in numerical form on the packaging, which may be directly printed on the front, side, or back of the packaging, or on the label or instruction manual on the packaging. The common annotation method may be "Production date: XXXX year XX month XX day" or simplified to "XXXX/XX/XX".
2. Check the bottle body or bottom: If Lisu facial mask is bottled or canned, check whether there is production date information on the bottle body or bottom. Some brands use laser engraving or coding to mark the production date on the bottom or side of the bottle. Similarly, this information may appear directly in the form of dates or be represented by abbreviations such as "MFG" followed by numbers.
3. Visit the official website or contact customer service: If you cannot find clear production date information on the packaging and bottle, you can try visiting the official website of the Lisu brand. Some brands provide product information inquiry services on their official websites, including production dates and expiration dates. You can also contact the customer service department of the Lishu brand and inquire about specific information about the production date by providing the product batch number or other relevant information.
Different batches and types of Lisu facial mask may have different production date marking methods, so it is recommended to try one by one according to the above steps until the correct production date information is found. At the same time, in order to ensure the quality and safety of the product, it is recommended to choose formal channels and reputable businesses when purchasing and using Lisu facial mask.
