DUOLAB skin care lot and date guide
Before you rely on the decoded date
- On DUOLAB products, inspect the capsule strip or pod tray, the carton flap, the device label. Where the outer box is available, read its mark alongside the container rather than choosing one without context.
- A DUOLAB lot code should not be confused with the device serial number or the barcode. Those label elements identify the retail product rather than its production run.
Common lookup mistakes
- Capture each DUOLAB concentrate capsule pack before loading it into the Formulator, preserving the pairing between formula and printed traceability mark.
- DUOLAB cartridges and the dispensing device need separate checks: verify cartridge sealing and formula appearance, then inspect the device for clean, reliable dosing.
