The method to check the production date of Balboa hyaluronic acid ampoules can be carried out according to the following steps:
1. Check the side of the packaging box: The production date of the Pattaya hyaluronic acid ampoule is usually marked on the side of the packaging box. Find a barcode like symbol with a line of numbers on it. This string of numbers consists of three parts: year, month, and day. The first two digits represent the last two digits of the production year, the middle two digits represent the production month, and the last two digits represent the production date. For example, "211021" indicates production on October 21, 2021.
2. Check the bottle body: If the information on the packaging box is not clear enough or has been lost, you can try searching for the production date on the bottle body. The production date is usually printed in the format of "YY/MM/DD" on the bottom or side label of the bottle. Similarly, the first two digits represent the year, the second two digits represent the month, and the last two digits represent the date.
3. Pay attention to the date format: As Pattaya is a German brand, its date marking method may differ from domestic customs. In Germany, dates are usually marked in the order of "day month year", but on product packaging, in order to be in line with international standards, the format of "year month day" may be used. When checking the production date, please pay special attention to the order in which the dates are arranged.
If none of the above methods can find the production date, it may be because the product packaging has been replaced or there are special circumstances. At this point, it is recommended to contact the official customer service of Pattaya or check the product information on the official website to obtain the most accurate production date information.
