The exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry. We do list expiration dates for the products on the website if they are available. Most products use the American Date Format (MM/YYYY or MM/DD/YYYY) for expiration date which you can see from the product page. Some products may only show the manufacturing date that is indicated often by abbreviations as (MFD, MFG, PROD). You can view the expiration date on the product page, next to the picture, in the details with the shipping weight and product code.
The shelf life of cosmetics depends on a 'period after opening' and 'production date'.
- Period After Opening (PAO): Some cosmetics should be used within a specified period of time after opening due to oxidation and microbiological factors. Their packaging has a drawing of an open jar and, inside it, there is a number representing the number of months. In the example below, the product expires 6 months after opening:
- Production Date: Unused cosmetics lose freshness and become dry. According to EU law, the manufacturer has to put the expiration date only on cosmetics whose shelf life is less than 30 months. The most common periods of suitability for use from the date of manufacture are:
- Skin Care: Minimum 3 years
- Makeup: Minimum 3 years for mascara type products to more than 5 years for powders.
