“Anytime you put on a sunscreen or a lotion, it can react with chlorine and byproducts can form, which are chlorinated byproducts that can potentially could be harmful and whether that's on your skin initially or it's floating in the pool and you get exposed, those are two main ways of having exposure,” Waldman said.
Waldman explained that the particular concern is ingesting it, such as “after swimming in a pool and putting your hand in your mouth or sucking your thumb,” she said.
Waldman's advice is to keep kids' hands out of their mouths, towel or shower off immediately after pool time, and consider look for a sunscreen with zinc.
Mothers told WFXT that they're going to make the switch.
“So yeah, we gotta think about that,” Brown said.
Waldman also said that despite all of this, people shouldn't stop using sunscreen altogether.
She said using sunscreen, even with avobenzone, is better than using nothing at all because going without it can lead to skin cancer.
