FAQs

Where can I find the batch code on my cosmetic product?

Batch codes are typically printed or embossed on the bottom, side, or crimped edge of the packaging, distinct from the barcode or product number.

How reliable is the cosmetic batch code checker?

COSR.AI strives for high accuracy by using publicly available data and common coding patterns. However, manufacturers may update their coding practices, so cross-checking with official expiration dates is recommended for critical purposes.

What should I do if my brand or batch code isn't recognized?

The database is continuously expanding. If your brand or code isn't identified, contact COSR.AI with the details to help improve the service.

How long do cosmetics typically stay fresh after manufacturing?

Unopened cosmetics usually last between 2.5 to 5 years if stored properly. Once opened, the Period After Opening (PAO) symbol indicates freshness, typically from 3 to 24 months.

Is it safe to use cosmetics past their expiration date?

Using expired cosmetics is not recommended. They may lose effectiveness, change in texture or color, and pose risks of skin irritation or infection. Adhering to freshness guidelines is safest.

How can I decode the expiry date of Japanese cosmetics?
