Where to find the batch code on Diadem products?

Finding the batch code on your Diadem product is essential for tracking its freshness. For skincare products like serums or creams, look at the bottom of the glass jar or plastic bottle. The code is often etched into the container or printed in a small, contrasting color.

If you have a tube (like a cleanser or hand cream), check the crimped seal at the very top. For boxed items, Diadem usually stamps the same alphanumeric code on the outer packaging near the barcode or ingredient list. Most Diadem batch codes consist of 3 to 6 characters, combining letters and numbers.

Important: Period After Opening (PAO)

While the batch code reveals the expiration date for unopened products, the **Period After Opening (PAO)** symbol is what you must follow once you use the product for the first time. Look for an "open jar" icon with a number followed by 'M' (e.g., 6M, 12M). This indicates how many months your Diadem product remains safe and effective after the seal is broken.

Frequently Asked Questions about Diadem

What is the shelf life of Diadem cosmetics?
Most Diadem products have a standard shelf life of 36 months when unopened. However, once a product is opened, you should refer to the PAO (Period After Opening) symbol on the packaging, which typically indicates a lifespan of 6 to 24 months.
Does Diadem print expiration dates on packaging?
Diadem often uses batch codes instead of explicit expiration dates for products sold in many regions. These alphanumeric codes allow you to determine the manufacturing date, which is the starting point for calculating its shelf life.
Can a batch code tell me if my Diadem product is authentic?
While a valid batch code indicates that the code format matches Diadem's manufacturing patterns, it is not a definitive proof of authenticity. Counterfeiters can sometimes replicate valid batch codes. Always purchase from authorized retailers to ensure product authenticity.
