VIEW OUR TESTING
Sunscreen was applied as prescribed by test instructions. A static SPF test was performed and our products were rated SPF 44.83. Testing was then initiated. Subjects were subjected to 30-minute intermittent periods in water using whirlpool at 75-80 degrees F, circulation jets on and jogging in place for the duration of immersion periods.
Tests were performed for 16 periods of alternating 30-minute immersions, 10-minutes out, yielding 8 hours (480 minutes) of immersion time. (80 minutes in and out of water is normal testing time on sunscreen/sunscreen products. Look for this information on the product.)
At end of the initial testing, products maintained rating of SPF 44 or higher. No adverse effects or any unexpected reactions of any kind were observed on any of the subjects, during or after any of the tests.
