Q: I’ve seen several TikTok videos claiming that sunscreen is toxic and might even cause cancer. Some influencers suggest it’s better to skip sunscreen altogether. Is there any truth to these claims?

A: This is a concerning trend. Misinformation about sunscreen is spreading rapidly on social media platforms like TikTok, leading many, especially younger individuals, to question its safety. Some influencers and celebrities have made unfounded claims suggesting that sunscreen is harmful or that sun exposure doesn’t cause skin cancer.

However, dermatologists and health experts strongly refute these assertions. Sunscreen is a critical tool in protecting the skin from harmful ultraviolet, or UV, rays, which are a leading cause of skin cancers, including melanoma. This misinformation poses significant health risks.

Surveys indicate that this misinformation is influencing public perception. A study by the Orlando Health Cancer Institute found that 1 in 7 American adults under 35 believe using sunscreen daily is more harmful than direct sun exposure. This is particularly alarming given that melanoma is one of the most common cancers in young adults.
