Where should I look for the IOPE code?
Start with the bottle base and rear-label edge, the jar base or rim, the carton flap on the IOPE item and its carton.
IOPE skin care lot code
IOPE spans Retinol Super Bounce Serum, Super Vital Cream, Vitamin C Expert, Bio Conditioning Essence. Start with the exact item and pack format, then look for its short production mark rather than assuming one position covers the whole range.
IOPE FAQ
Should the barcode or volume be entered as an IOPE lot code?
No. Record the compact IOPE production mark and its position on the container or box.
IOPE — Do matching products always share one lot?
For the product in hand, no. Record the production mark on each item rather than assuming the same manufacturing run.
IOPE skin care lot and date guide
Before you rely on the decoded date
- On IOPE products, inspect the bottle base and rear-label edge, the jar base or rim, the carton flap. Keep the carton long enough to photograph both marks when the product and box are labeled separately.
- The IOPE production mark is separate from the barcode or volume. That information identifies the item, formula, size, shade, or required label.
Common lookup mistakes
- Tilt IOPE pump bottles and glossy cream jars to reveal pale base printing, and keep the Korean carton text in the same photo for context.
- IOPE cushions require clean puffs and a secure inner closure, whereas serums and creams need stable dispensing and texture. Apply the printed Korean expiry when present.
