Debora Rasio’s sun‑melanoma claim sparks rebuttal from Italian dermatologists
Nutritionist and oncology specialist Debora Rasio posted an Instagram video asserting that increased solar exposure protects against melanoma, that sunscreen creams raise the risk of skin cancers, and that vitamin D generated by sun exposure is the most important protective factor. She cited several studies to support these statements.
The Italian Society of Dermatology and Sexually Transmitted Diseases (SIDeMaST) responded, calling the claims “mistificazione e follia.” The society reaffirmed that ultraviolet (UV) rays are carcinogenic and the primary cause of skin cancers and warned that false messages from medical professionals are especially dangerous. SIDeMaST emphasized the established protective role of sunscreen and proper photoprotection.
In line with the society’s guidance, health experts advise using broad‑spectrum sunscreen with at least SPF 30, applying it correctly and reapplying regularly, seeking shade, and avoiding peak UV hours. The World Health Organization recommends protective measures when the UV index reaches 3 or higher.
