A-Derma batch code & expiration date

Where to find your A-Derma batch code

The A-Derma batch code is a short, usually embossed stamp of letters and numbers — never the barcode. Here’s what it looks like on typical packaging (the code is the short embossed stamp, not the long barcode):

The A-Derma batch code — also called the lot code, lot number or serial number — is a short 4–8 character stamp of letters and numbers, usually embossed rather than printed in ink, and it is never the barcode. On a bottle or jar look at the base; on a tube look near the crimp/seal at the end; on a boxed perfume or fragrance check a flap or side of the box; on makeup check the underside of the compact or inside the pan.

• Bottle / jar — stamped on the base.
• Tube — near the crimp or seal at the closed end.
• Boxed fragrance — a flap or side of the outer box (and often on the bottle base too).
• Compact / palette — the underside, or inside the pan.

About A-Derma batch codes

A-Derma doesn't publish how its batch codes work, and we have never been able to read one. Under EU rules a batch number doesn't have to contain a date at all. Use the pack instead: a printed "best before end" date, or the PAO open-jar symbol telling you how many months it lasts once opened.

Most unopened cosmetics and fragrances keep for about 30–36 months from manufacture. Once opened, follow the PAO (open-jar) symbol — it usually matters more than any printed expiration date.

Can the batch code tell me if my A-Derma is authentic? Not on its own. A code that decodes to a sensible date is a good sign, but counterfeiters copy real codes from genuine packs, so a valid code cannot prove a A-Derma product is authentic. Buy from A-Derma or an authorised retailer, and compare the packaging, print quality and seal with one you know is genuine.

Does A-Derma expire?

Yes — like all cosmetics and fragrances, A-Derma products have a limited shelf life. Unopened they typically last 30–36 months from the manufacture date, and the batch code above tells you how old yours already is. After opening, the PAO (open-jar) symbol — e.g. "12M" — is a better guide than any printed expiration date.

How long A-Derma products last

Unopened: general cosmetics guidance. Opened: general guidance by product type. A date or open-jar symbol on your pack always wins.
