Not Affiliated with Brands

CosmeticBatchTool is an independent utility application. We are not affiliated with, endorsed by, sponsored by, or associated with any of the cosmetic brands whose batch codes we decode (including but not limited to Estée Lauder, L'Oréal, LVMH, Shiseido, etc.). All product names, logos, brands, trademarks, and registered trademarks are property of their respective owners.

Accuracy of Production and Expiration Dates

The production dates and estimated expiration dates provided by CosmeticBatchTool are calculated using advanced algorithms based on historically known batch code formats. However, please be aware that:

• Algorithms may contain errors or logic flaws.
• Brands frequently change or reuse their batch code systems without public notice.
• The same batch code might mean different things depending on the product line or manufacturing facility.

Therefore, CosmeticBatchTool cannot guarantee that the dates displayed are 100% accurate. The results returned by our tool should be used as an estimate and a reference guide, rather than absolute fact.

No Health or Medical Advice

The use of expired cosmetics can cause skin irritation, allergic reactions, or infections. CosmeticBatchTool provides estimates on shelf life but does not provide health or medical advice.

Always use your best judgment: if a product smells off, has changed color, or has separated, it should be discarded regardless of what any batch code decoder says. When in doubt about a specific product's safety, please contact the manufacturer directly using the contact information on the physical packaging.

Limitation of Liability

Under no circumstance shall we have any liability to you for any loss or damage of any kind incurred as a result of the use of the site or our batch checking application. Your use of the site and your reliance on any information on the site is solely at your own risk.
