La Mer FAQ
Where can I find the La Mer batch code?
For La Mer creams, serums, eye products, and premium skincare jars, start with the jar bottom, box bottom, bottle base, or small label-edge printing. Use one complete lot marking from one package location, not the barcode or shade reference.
What should I check before using older La Mer products?
Use the batch-code result with official labels, PAO symbols, packaging condition, and product changes. Be especially careful with expensive resale products, opened jars, and older backup stock.
What if a La Mer code cannot be read?
Recheck the brand, copy every character exactly, keep leading zeroes, avoid barcode numbers, and inspect whether the box or container has another printed lot marking.
Can a La Mer batch code prove authenticity?
No. It can support freshness and traceability checks, but authenticity still depends on seller reliability, packaging details, formula, and official brand information.
