Some sunscreens stay on in the water better than others, but no sunscreen is truly waterproof, so it's important to get out of the water and reapply if you are swimming for long periods no matter which sunscreen you use.

In 2011 The Food and Drug Administration (FDA) announced it was banning the use of the term “waterproof” by sunscreen manufacturers. According to the FDA, the terms "waterproof" and "sweat proof" are misleading because sunscreens resist the water only for a limited period of time. Eventually, they all wash off. Sunscreen labels must indicate how long (usually 40 or 80 minutes) the product remains effective in water as confirmed by standardized lab tests.
