It's one of many false claims about sunscreen doing the rounds on social media this summer and Australians are being warned not to fall for it.

Anti-sunscreen rhetoric has exploded on social media, according to a 2024 study from the International Society of Digital Health in Dermatology, and claims that sunscreen causes skin cancer or contains hormone-blocking chemicals are on the rise online.

"We have seen a huge spike in misinformation about the causes of skin cancer, in particular the role of sunscreen, which is very disturbing," Liz King, Manager of Skin Cancer Prevention at Cancer Council NSW, told 9news.com.au.

Young people are particularly at risk of encountering this kind of misinformation because almost half of Aussies aged 18–24 cited social media as their main news source in a recent ACMA report.

It has experts worried that young Aussies could be swayed to skip sunscreen by baseless claims pushed online, potentially increasing their risk of developing skin cancer.
