With regards to Ultrasun, I saw a post elsewhere about the batch codes and the year of manufacture. The poster had contacted Ultrasun and it transpires that some of the batch code sites aren’t correct.
Apparently with Ultrasun, a batch code ending in -44 was manufactured in 2019. If it ends in -45 it was manufactured in 2020 and if it ends in -46 it was in 2021 ….. and so on.
The month of January is an A, February is B through to December which is M instead of L. This is so there is no confusion with September which is the letter i
They also confirmed that any product manufactured from November 2019 has no shelf life as such because of the stability of the formula but they should be used within two years of opening.
i wonder if anyone else is as confused as I am?
