I don't get a reasonable result. Is my product genuine?
The calculator is able to convert batch code to a production date or expiration date. There isn't a common database for all the cosmetics products. So it cannot be used to check if your product is genuine. If you buy your product from a trustable source, you don't need to doubt.
If you put in other code instead of the correct batch code, the calculator can get a wrong result. Or if the cosmetics company has changed their way to make batch code, the calculator cannot get a correct result either.
Can the calculator calculate more products?
I would like to add more brands to the calculator. But some companies don't open their way to make batch code. I can only convert a small amount of brands that I know. If you know how to convert a brand's batch code, please kindly inform me so I can add it to the calculator.
