FAQ
Common questions
What is a batch code?
It’s a short string of letters and numbers stamped or printed on the pack. Brands use it to trace a product back to the run it was made in. Many also hide the manufacture date inside it, and that’s the part Cosmetic Checker reads.
Where do I find it?
Usually on the bottom of a bottle or jar, along the crimped edge of a tube, or on the outer box. It’s often tiny and sometimes etched, so tilt it under a light. The batch code guide has more detail.
How accurate is the date?
When we know how a brand writes its codes, the date comes straight from the code. The shelf life is a general estimate for that type of product, not a promise from the manufacturer. Treat it as a guide, and trust your nose and eyes too.
Which brands are covered?
More than 500 makeup, skincare and fragrance brands are in the list. Some brands don’t use a readable system, so a few codes can’t be dated. When that happens, the app says so instead of guessing.
Batch code or PAO symbol?
They answer different questions. The batch code tells you when something was made. The PAO symbol, the little open jar with a number like 12M, tells you how long it lasts once opened. While a product is sealed, go by the batch code. After you open it, the PAO usually matters more.
Is it free? Do I need an account?
It’s free, and ads pay for it. There’s no account to create. Your history is saved on your phone.
What data do you collect?
Your history stays on your phone. The app uses Google AdMob for ads and Firebase for usage and crash reports, and it asks for your consent where the law requires it. The details are in the privacy policy.
