Patou Batch Code Guide

What is a Patou Batch Code?

A Patou batch code is a code composed of letters and numbers used to identify the production batch of a product. Through the batch code, you can determine the production date and assess whether the product is within its shelf life.

The Patou batch code is different from the product's Barcode. Barcodes are used for checkout and inventory management and do not contain production date information; the batch code is the key to finding the production date.

Patou Batch Code FAQ

Why can't I find my Patou batch code?+

Patou encoding rules may have updated, or the batch code is worn and unrecognizable. If it's a newly launched product, our database may not have been updated yet. You can also contact Patou official customer service to confirm.

Can Patou batch code checker verify authenticity?+

Batch code checking cannot be the sole basis for authenticity verification. Finding a batch code doesn't guarantee the product is genuine, but if the code cannot be found or the format is obviously suspicious, exercise caution. We recommend purchasing Patou products through official channels.

Can I use expired Patou products?+

We do not recommend using expired cosmetics. Expired products may cause skin allergies, acne, or infections, especially eye products. For your skin health, please use Patou products within their shelf life.

How to store Patou cosmetics to extend shelf life?+

Store Patou products in a cool, dry, dark place. The high temperature and humidity of bathrooms accelerate product deterioration. Products with active ingredients (like Vitamin C, Retinol) should be refrigerated.
