Where Lab Series stamps its code: outer box base crimp + flacon base
3-character code embossed on the box crimp and printed on the flacon base sticker.
- Read the code off the box base crimp in raking light — authentic embossing has uniform depth.
- Read the flacon base or label code and enter it above — the two must match character for character.
- Check for scraped, re-embossed or stickered-over crimps: a classic way to hide aged gray-market stock.

Frequently Asked Questions
How do I decode a Lab Series batch code?
Lab Series is part of The Estée Lauder Companies and uses the Estée Lauder Companies Pattern: [Run / plant letter][Month 1–9 / A=Oct / B=Nov / C=Dec][Year digit]. Worked example: B64 reads as B = Batch run B (2nd), 6 = June, 4 = 2024 — produced June 2024. High — 3-character ELC code used across fragrance, skincare and colour. A correctly formatted code is necessary but never sufficient proof of authenticity, because counterfeiters copy real codes.
Where is the batch code stamped on a Lab Series box and bottle?
3-character code embossed on the box crimp and printed on the flacon base sticker. Look on the outer box base crimp and the flacon base. The code on the box and the code on the flacon must match character for character; a scraped, re-embossed or stickered-over box crimp is a classic sign of aged gray-market stock.
How long does Lab Series last and where can I buy fresh-batch authentic products in Singapore?
Unopened, Lab Series skincare is a fresh batch for 24 months from production and should be used within about 36 months, as vitamin C, retinoids and peptides degrade with time. In Singapore, buy from Lab Series authorised counters and the brand's official online store, and check that the decoded production date is recent before you pay.
