Avene spf50
This sunscreen only protects us well from UVC as the graph plummets down after around 280 nm.
The graph about the percentage of blocked light clearly shows that the sunscreens with higher spf such as 50 or 50plus had a considerabley higher protection barrier than sunscreens which had 30 or less.
We know that these results are correct as we took an average of our readings.

We found that avene spf 50 was the worst sunscreen as it only protected UVC.
