Where Anua stamps its code: outer box base crimp + flacon base
Printed on the bottom base of Heartleaf 77% Soothing Toner bottles, Heartleaf Pore Control Cleansing Oil pumps, and Niacinamide 10% + TXA 4% Dark Spot Correcting Serum dropper bottles.
- 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.

- Reported Notes
- Anua (The Founders Inc., Seoul) prints a 4-to-8-character alphanumeric batch number alongside an explicit Korean YYYY.MM.DD manufacture (제조) and expiration (사용기한 / 까지) date on the base of every bottle and carton. Unopened Heartleaf 77% toners, cleansing oils, and sunscreens remain stable for 36 months (24 months for Niacinamide 10% + TXA 4% and Azelaic Acid 10% serums); observe the 12M PAO symbol after opening.

Frequently Asked Questions
Can I decode a Anua batch code?
Anua 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): Anua (The Founders Inc., Seoul) prints a 4-to-8-character alphanumeric batch number alongside an explicit Korean YYYY.MM.DD manufacture (제조) and expiration (사용기한 / 까지) date on the base of every bottle and carton. Unopened Heartleaf 77% toners, cleansing oils, and sunscreens remain stable for 36 months (24 months for Niacinamide 10% + TXA 4% and Azelaic Acid 10% serums); observe the 12M PAO symbol after opening. To check freshness, read the printed EXP or MFD date or the PAO (open-jar) symbol, or give the lot number to Anua customer service. A correctly formatted code never proves authenticity.
Where is the batch code stamped on a Anua box and bottle?
Printed on the bottom base of Heartleaf 77% Soothing Toner bottles, Heartleaf Pore Control Cleansing Oil pumps, and Niacinamide 10% + TXA 4% Dark Spot Correcting Serum dropper bottles. 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 Anua last and where can I buy fresh-batch authentic products in Singapore?
Unopened, Anua 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 Anua authorised counters and the brand's official online store, and check that the printed EXP / MFD date is recent before you pay.
