Why does my Derma product have no expiry date?
Derma explains that products with unopened shelf life longer than 30 months may omit one; look for PAO and the traceable batch instead.
Check Derma Cosmetic Batch Code
Derma is a Danish skin, body, baby and sun-care brand. Its own guidance says many products have no expiry date because unopened shelf life exceeds 30 months, while traceable batch numbers remain on the packaging. A jar symbol describes time after opening; it does not reveal when the product was made.
Derma FAQ
Where is the Derma batch number?
Check tube seam, bottle base, lower back label and any carton flaps.
Does 12M show manufacture date?
No. It means the recommended period after opening, not the factory date.
Derma batch numbers, expiry dates and PAO
Before you rely on the decoded date
- Look along tube crimps, bottle bases, back labels and carton flaps for an inked or embossed batch; sunscreen may place supporting date text near the lower seam.
- Only treat text explicitly labelled as manufacture or production as a manufacture date. An opaque batch, PAO jar and printed expiry serve different purposes.
Common lookup mistakes
- Retain the carton for sun and baby products until both batch and any expiry wording have been recorded.
- Replace sunscreen after heat exposure, separation, damaged packaging or a changed smell even when its printed period has not ended.
