FAQs
-
How do I find the batch code on my cosmetic product?
Batch codes are typically printed or embossed directly on the product container (bottom, side, or crimped edge of a tube) or on its outer packaging. They are usually a short sequence of letters and numbers, varying in format from brand to brand. -
How accurate is the cosmetic checker?
COSR.AI strives for high accuracy by utilizing publicly available information, common batch code patterns, and data contributed by users and brands. However, manufacturers can change their coding systems without notice, so it's recommended to cross-reference with any explicit expiration date printed on the product. -
What if my brand is not listed or the batch code is not recognized?
The database is continuously expanding. If your brand isn't listed or a code isn't recognized, you can contact COSR.AI with the brand name and batch code to help improve the service. -
How long are cosmetics fresh after manufacturing?
Unopened, most cosmetics have a shelf life of 30 months (2.5 years) to 60 months (5 years) if stored properly in a cool, dark place. Once opened, the Period After Opening (PAO) symbol dictates freshness, typically ranging from 3M for eye products to 12M or 24M for other items. -
Can I use cosmetics after their expiration date?
It's generally not recommended. Expired cosmetics can lose their efficacy, change in texture or color, and harbor harmful bacteria, potentially leading to skin irritation, infections, or allergic reactions.
