Most likely La Mer code locations
For La Mer, start with the box bottom. If the outer box is missing, move to the jar base and then the bottle base.
Check the label around each marking to distinguish the production lot from product references; position and character count alone do not identify a lot.
- Check the box bottom under bright side light.
- Check the jar base under bright side light.
- Check the bottle base under bright side light.
Numbers to ignore
Do not enter the retail EAN/UPC product number, shade number, SKU, ingredient registration number, or volume marking as the batch. Some scannable codes contain additional fields; use only an explicitly identified lot field, not the entire scan.
If several La Mer codes appear, identify the production lot from its label and the instructions for that product. Length alone cannot identify it. Keep every mark with its original location and never trim a longer identifier to make it fit.
When the print is hard to read
Embossed or low-contrast batch codes are easier to read with side lighting. Take a photo, zoom in, and preserve leading zeroes, separators, and letter case.
If the box and container disagree, check whether one string is a product reference. Preserve both markings separately while confirming their purpose.
La Mer product and package context
Look beneath the jar or bottle, along a label edge, on a tube crimp, or on the carton flap. Long retail identifiers and jar molding marks are not the batch code.
Where is the La Mer cream batch code? Inspect the jar base and outer carton for a short printed or etched production mark, separate from the barcode and packaging molds.
