In this Sun Bum Daily Face Liquid Moisturizer SPF 50 sunscreen lotion review, I find a decently performing sunscreen formulation. Thanks go to Chris for the sunscreen sample!
This sunscreen exhibited decreasing UV protection the longer the sample was in the testing machine (due to desiccation). At the end of the 2 hour testing routine, the detected UV was approximately 3-3.5. This means the UV blocking ability of the formula was roughly at 86-88% UV blocking effectiveness, this put the SPF at around a high SPF 30 level at around the 2 hour mark. The results below are the average of the entire 2 hour testing schedule, which I believe still produced decent results. But if one uses this product, I really recommend reapplying after 2 hours.
The Sun Bum Daily Face Liquid Moisturizer SPF 50 is a chemical sunscreen formula which contains Avobenzone at 3%, Homosalate at 9%, Octisalate at 5%, and Octocrylene at 10%.
The Sun Bum Daily Face Liquid Moisturizer SPF 50 sunscreen reduced 93.62% of irradiated UVA, 89.87% UVB, and 93.39% of total UVI. Not bad!

Testing notes:
Although testing indicated positive results, I really recommend reapplying after 2 hours as the protection decreased to about a SPF 30 at the end of the 2 hour testing duration.

Despite the decent test results, the tendency to decrease in UV protection makes me a little hesitant to give this a high rating.
