Sunscreen and Blue Light Protection
Anyone ever experience doing an actual clinical test for Blue Light Protection of sunscreen products? I understand SPF and PA rating already have established clinical protocols. But how can blue light protection be determined?

I haven’t any experience in testing for this specifically.
Perhaps this paper would be of interest.
https://onlinelibrary.wiley.com/doi/abs/10.1111/jocd.13854But their conclusion is relevant… “There is not a formal standardized method to test for blue light protection; however, spectrophotometers, imaging devices, measuring oxidative stress, and visual evaluations are some of the methods being used today.“
So, this is an emerging field and no one has really worked out the best way to measure.

If you are making a product and want to claim for blue light protection. DSM have a product called Pepha Age. It is supposed to protect your skin from blue light also coming from the computer.
Look and see if they have done any clinical trials, they usually do so they can back up the ingredients they make. They are also very nice and approachable. They may send you a sample to try.
hope this helps
