The amount of sunscreen ultraviolet filters (UVF) rinsed off while swimming in the ocean varies based on the product’s formula, a new study has found.

Neutrogena parent company Kenvue conducted a study, in collaboration with nonprofit applied science and technology organization Battelle, on the rinse-off levels of certain sunscreens to determine how much product seawater removes from the skin while users are in the ocean.
