Where UniSkin prints the batch code

Bottom of the bottle
Bottom of the bottlePrinted in small type, or stamped straight into the material.
Crimp of the tube

This one is the barcode, not the batch code

A barcode is 12–14 plain digits. It identifies the product itself, not this particular batch — there is no date in it. This is the most common mix-up.

Common mistakes with UniSkin codes

  • Copy the code exactly as printed — keep leading zeros, keep letters, and drop any spaces or dashes you see between groups.
  • 0 and O, 1 and I, 8 and B are the three pairs people misread most. If the print is faint, tilt the package under a light before guessing.
  • The box and the bottle can carry different codes. They are usually filled at the same time, but if they disagree, trust the one on the item itself.

What the date does and doesn't tell you

  • It is the manufacture date, not an expiry date. Unopened shelf life runs from it; once opened, the period-after-opening symbol on the pack takes over.
  • It says nothing about how the product was stored. Heat, sunlight and a car glovebox age a product far faster than the calendar does.
  • It is not a proof of authenticity. A code that decodes cleanly only means it fits the brand's own scheme — it cannot tell a genuine item from a good copy.

UniSkin — frequently asked

Where is the batch code on UniSkin products?
Look on the base of the bottle or jar, the crimped tail of a tube, or the bottom flap of the box. It is a short string stamped or printed in small type — not the barcode.
Is a UniSkin lot number the same as a batch code?
Yes — lot number, lot code and batch code all mean the same string on your UniSkin packaging. American packaging and shoppers tend to say lot number; British and European ones say batch code. Enter it either way.
Can I tell the expiry date from a UniSkin batch code?
The code gives the manufacture date. Shelf life is counted from there — typically 36 months unopened, and 6–12 months once opened, depending on the product.
Is the barcode the same as the batch code?
No. The barcode is the 12–14 digit number under the striped label and identifies the product, not the batch — it contains no date at all. This is the single most common mistake.
