What I want to tell you is that the general L 'Oré al batch number consists of 5 yards, 2 English letters and 3 numbers.
The bottle batch number is different from the packaging batch number. That's right.
28 stands for French original, e stands for 2008, and 307 stands for the 307th day of 2008, so it should be produced around the end of 10!
One more thing: the L 'Oré al brand has different origins around the world. At present, there are three main producing areas: French/Indonesian/China.
The packaging of each place of origin is different, including the usage of the production batch number.
