(FILES) Tourists enjoy sunbathing at Waikiki Beach in Honolulu, Hawaii, on January 1, 2010. Dismissively tossing a tube of sunscreen over his shoulder, a bare-chested TikTok influencer declares that the cream causes cancer. He instead promotes "regular sun exposure" to his 400,000 followers -- contradicting US dermatologists fighting a surge in such dubious misinformation. In the midst of a blazing summer, some social media influencers are offering potentially dangerous advice on sun protection, despite stepped-up warnings from health experts about over-exposure amid rising rates of skin cancer.
