In this Paula’s Choice Resist Youth-Extending Daily Hydrating Fluid review, I find a lower performing SPF 50 sunscreen. Thanks for the sample Jennifer!
The Paula’s Choice Resist Youth-Extending Daily Hydrating Fluid is a chemical sunscreen formula which contains Avobenzone at 2%, Octinoxate at 7.5%, Octisalate at 5%, and Octocrylene at 2%.
The Paula’s Choice Resist Youth-Extending Daily Hydrating Fluid reduced 64.16% of irradiated UVA, 54.40% UVB, and 63.57% of total UVI. Not the best results for a SPF 50 rated sunscreen!

Testing notes:
I can think of other sunscreen that I would choose before this one.
Not really recommended due to the subpar SPF 50 protection and desiccation problems.
