COSR.AI is a free online tool that takes the guesswork out of cosmetic safety. Simply enter a brand name and batch code to instantly discover the manufacturing date, estimated shelf life, and expiration details for thousands of beauty brands worldwide. Using expired makeup or skincare can lead to bacterial growth, skin irritation, diminished efficacy, or wasted money — COSR.AI helps you avoid all of that by empowering you to make informed decisions about your beauty routine. Beyond just checking dates, COSR.AI also serves as an educational resource, teaching users how to locate batch codes on packaging, decode PAO (Period After Opening) symbols, and follow best practices for safe cosmetic storage. Stay informed, stay safe, and get the most out of your beauty products.
