Where SKIN1004 stamps its code: outer box base crimp + flacon base
Ink-jet printed on the bottom base of Madagascar Centella Ampoule dropper bottles and Light Cleansing Oil pumps, or embossed on the top crimp seal of Hyalu-Cica Water-Fit Sun Serum SPF 50+ PA++++ tubes.
- 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
Can I decode a SKIN1004 batch code?
SKIN1004 has not published how its lot code encodes the production date, so Beauty.net records the lot number and checks its format but does not estimate a date. Reported notes (from the batch-code reference cited below, not verified by Beauty.net): SKIN1004 stamps a 4-to-7-character alphanumeric lot code together with a direct Korean YYYY.MM.DD manufacture (제조) and expiration (까지) date on the bottom of Madagascar Centella glass bottles and Hyalu-Cica tube crimps. Unopened Hyalu-Cica sun serums, cleansing oils, and creams last 36 months (24 months for 100% Madagascar Centella Ampoules); follow the 6M–12M PAO symbol once opened. To check freshness, read the printed EXP or MFD date or the PAO (open-jar) symbol, or give the lot number to SKIN1004 customer service. A correctly formatted code never proves authenticity.
Where is the batch code stamped on a SKIN1004 box and bottle?
Ink-jet printed on the bottom base of Madagascar Centella Ampoule dropper bottles and Light Cleansing Oil pumps, or embossed on the top crimp seal of Hyalu-Cica Water-Fit Sun Serum SPF 50+ PA++++ tubes. 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 SKIN1004 last and where can I buy fresh-batch authentic products in Singapore?
Unopened, SKIN1004 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 SKIN1004 authorised counters and the brand's official online store, and check that the printed EXP / MFD date is recent before you pay.
