Where is a Conny sheet-mask code?
Look along the top and bottom seals and across the back, especially near the barcode.
Check Conny Cosmetic Batch Code
Conny's available range is led by Korean-style sheet masks, including aloe, charcoal, collagen, hyaluronic acid, ginseng, and animal-print variants. The line also includes Specialist eye cream, face-wash gel, and an overnight mouth mask, so the pack seam matters as much as the bottle or tube base.
Conny FAQ
Is 21 ml or 23 g the batch number?
No. That is the declared fill amount and repeats on the same mask format.
Do Conny cream and mask packs use the same placement?
Usually not; tubes and bottles use a base or crimp, while sachets use a sealed edge or back print.
Conny codes on sachets, tubes, and bottles
Before you rely on the decoded date
- For a single-use mask, inspect both heat-sealed edges and the back panel; for eye cream or cleanser, check the crimp, base, lower label, and cap area.
- The ingredient callout, mask character, 21 ml or 23 g fill, and 1 pc notation identify the variant and are not the production lot.
Common lookup mistakes
- Photograph a sachet before opening because the code can be cut through or smeared when the seal is torn.
- Keep unused masks flat and sealed; once a single-use pouch is opened, its printed lot does not make leftover essence suitable for storage.
