What does water resistant mean with respect to sunscreens?
A sunscreen is considered ‘water resistant’ if the SPF is effective after 40 minutes of water immersion. Some sunscreens are labeled as ‘very water resistant’ but the term ‘water proof’ is being phased out as it in misleading. One must recognize that sunscreen needs to be reapplied regularly throughout the day to maintain maximal effectiveness even they are considered water resistant.
