CosmeticBatchTool

CosmeticBatchTool is a free browser-based reference tool for people checking cosmetic packaging. Select a brand and enter a supported batch code to estimate a production date and product age. Coverage varies by brand, code format, market and product range; some brand pages provide label guidance rather than a date decoder. The site also includes a searchable brand directory, illustrated guidance on finding batch codes, explanations of manufacturing and expiry labels, and a manual period-after-opening calculator using dates and periods entered by the user. It works without an account. Results are estimates. A batch-code match does not establish product authenticity, storage conditions, an exact expiry date or whether a product is safe to use. Follow the package instructions and contact the manufacturer when a code or result is unclear.
