Kosas FAQ

Where is a Kosas production lot printed?

Look on the carton bottom, bottle or tube base, crimp, compact underside, or label edge.

Can I enter a Kosas shade number?

Kosas: No. Shade, SKU, size, and barcode text identify the retail item and should remain outside the lot lookup.

Do all Kosas products use the same freshness rule?

No. Complexion, lip, brow, deodorant, and skincare-hybrid formats differ in PAO, contact, hygiene, and formula behavior.

Separating Kosas production lots from makeup labels

Before you rely on the decoded date

  • Revealer shade names, color numbers, product references, and retail barcodes identify a Kosas variant rather than a manufacturing run.
  • Complexion liquids, lip products, brow products, deodorant, and treatment formulas need different opening and hygiene decisions.

Common lookup mistakes
