What does COSR.AI do?
COSR.AI is a straightforward web tool designed to help consumers check the freshness of their cosmetics. You select a brand, enter the batch code found on the product packaging, and the tool provides the manufacturing date, typical shelf life, and an estimated expiration date. It takes the guesswork out of deciphering those cryptic strings of letters and numbers, giving you a clear answer on whether your product is still good to use.
The tool works by referencing a database of brand-specific batch code formats. It covers hundreds of popular and niche brands, from Dior to Glossier, and is regularly updated. Beyond the core checker, COSR.AI serves as an educational resource, explaining key terms like shelf life, Period After Opening (PAO) symbols, and where to find codes on different types of packaging. The interface is clean and the process is fast, delivering results without requiring an account.
This tool is most useful for anyone who buys cosmetics, especially from online retailers, sales, or duty-free shops where product age might be uncertain. It helps you avoid using expired products that could be less effective or cause skin irritation, and it can help you prioritize which items in your collection to use first. It's a simple, practical resource for making more informed decisions about your beauty routine.
