INRYU Batch Code Guide

What is a INRYU Batch Code?

A INRYU 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 INRYU 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.

INRYU Batch Code FAQ

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

INRYU 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 INRYU official customer service to confirm.

Can INRYU 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 INRYU products through official channels.

Can I use expired INRYU 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 INRYU products within their shelf life.

How to store INRYU cosmetics to extend shelf life?+

Store INRYU 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.
