Overview

• In a video released July 28, Yannick Neuder condemned TikTok and Instagram challenges like “sun-tattoo,” “burn-lines” and “tan-lines” that encourage unprotected sun exposure for fleeting online views.
• These trends involve deliberately skipping sunscreen or using oils to create sharply defined tan or burn marks by exposing skin during peak UV hours.
• Santé publique France data show that between 112,960 and 194,800 skin cancers diagnosed annually are linked to excessive UV exposure, with childhood sunburns significantly elevating melanoma risk.
• The Institut national du cancer states there is no safe tan, explaining that any skin darkening from UV exposure indicates DNA damage.
• Health authorities recommend applying SPF 50+ sunscreen every two hours, wearing UV-protective clothing, hats and sunglasses, and avoiding sun exposure during peak hours.
