All of our sunscreens have the highest possible Water Resistance rating of 80 minutes. Waterproof is no longer a claim that can be made according to the ruling made by the FDA in 2011. There are only two allowed Water Resistant ratings, 80 minute or 40 minute. Advances in research have allowed companies to formulate sunscreens that adhere well to your skin. However, regardless of the claims, you will have to reapply if you’re sweating heavily or doing activity in the water.
