RESUMEN
Although social media ubiquitously supplementstraditional information sources such as newspapers,magazines, radio, and television, investigation of onlinehealth information related to sun protection and skincancer prevention has been scarce and largely limitedto English language sources. Using the search terms"sun protection," "sunscreen," "skin cancer prevention,""tanning bed" and "vitamin D," we investigated 281YouTube videos presented in 6 languages: English,German, French, Spanish, Swedish, and Danish. Foreach video, we used a four-sectioned checklist toassess general information, popularity, expert drivenmeasures, and heuristic driven measures. Differencesbetween languages were detected: English languagevideos were most frequently viewed (median numberof views: 5488 compared to 248 -1591 in otherlanguages). Approximately 60% of videos revealednegative effects of solar ultraviolet (UV)-exposure.The majority of videos (75%) targeted adults. Videoson tanning beds and sunscreen contained false ormisleading information 40% and 20% of the time,respectively. We confirm observations made withrespect to other medical disciplines that the generalquality of YouTube contributions is often inferiorand does not deliver sustainable information. Othersources of information should be included whensearching for health information online.

The incidence of malignant melanoma (MM) continues to rise in the United States. While sun protection and full body skin examinations remain the mainstay of preventative care, chemoprevention of the deadly disease has become an increasingly popular field of study. In this focused review, we discuss current findings and analyze the risks and benefits of various agents investigated for the primary and secondary chemoprevention of MM. Such agents include topical retinoids, vitamins, and supplements, Polypodium leucotomas extracts, non-steroidal anti-inflammatory agents (NSAIDs), statins, sunscreens, and field therapy with topical imiquimod for primary and secondary chemoprevention. We further identify a need for expanded high quality human research on the topic.
